Hope this helped! :)

In the expression 3x+10, there are two terms: 3x and 10. The coefficient is 3, which multiplies the variable x, and the constant is 10, which is the term without a variable.

In the expression 3x+10, the terms are 3x and 10. A term is a single mathematical expression. The coefficient is a numerical or constant quantity placed before and multiplying the variable in an algebraic expression, so here the coefficient is 3, which is the number multiplying the variable x. The constant is a term without a variable, and in this case, it is 10.

Answer:

x = 4

Step-by-step explanation:

Step 1: Combine like terms

9x + 6 = 42

Step 2: Isolate x by subtracting 6 on both sides

9x = 36

Step 3: Isolate x by dividing by 9 on both sides

x = 4

3x+6+6x=42

9x+6=42

9x+6-6=42-6

9x= 36

Divide by 9 for 9x and 36

9x/9=36/9

x=4

Check answer by using substitution method

3(4)+6+6(4)=42

So you have 64 possible combinations.

Answer: fixed costs of production

The business application that would utilize the slope-intercept form of a linear equation is 1."break-even analysis." therefore, option 1.break-even analysis is correct.

In break-even analysis, you are trying to find the point at which your total revenue equals your total costs, resulting in zero profit (break-even point). This analysis often involves linear equations, and the slope-intercept form (y = mx + b) is commonly used to represent cost and revenue functions. The slope (m) represents the variable cost per unit, and the y-intercept (b) represents the fixed costs.

The other options, "fixed cost of production," "scheduling employee vacation," and "scheduling of employee," may involve mathematical modeling and equations, but they do not typically use the slope-intercept form of a linear equation for the primary analysis. Instead, these applications may involve other types of equations or mathematical models.

Answer:

(g ° h)(-3) = 8/5 ⇒ first answer

Step-by-step explanation:

* Lets explain the meaning of the composition of functions

- Composition of functions is when one function is inside of an another

 function

# If g(x) and h(x) are two functions, then (g ° h)(x) means h(x) is inside

  g(x) and (h ° g)(x) means g(x) is inside h(x)

* Now lets solve the problem

∵ g(x) = [tex]\frac{x+1}{x-2}[/tex]

∵ h(x) = 4 - x

∵ (g ° h)(x) means h(x) is inside g(x)

- Find (g ° h)(-3) means find h(-3) at first and then replace the value of

 h(-3) by the x of g(x)

* Lets find h(-3)

∵ h(x) = 4 - x

- Replace the x by -3

∴ h(-3) = 4 - (-3) = 4 + 3 = 7

- Now find g(7), means replace x by 7

∵ g(x) = [tex]\frac{x+1}{x-2}[/tex]

∴ g(7) = [tex]\frac{7+1}{7-2}=\frac{8}{5}[/tex]

∴ (g ° h)(-3) = 8/5

Answer:

 [tex]y_1=-\frac{1}{2}\\\\y_2=-\frac{3}{2}[/tex]

Step-by-step explanation:

The Quadratic formula is:

[tex]y=\frac{-b\±\sqrt{b^2-4ac} }{2a}[/tex]

Given the equation [tex]4y^2+ 8y +7 =4[/tex], you need to subtract 4 from both sides:

[tex]4y^2+ 8y +7 -4=4-4[/tex]

[tex]4y^2+ 8y +3 =0[/tex]

Now you can identify that:

[tex]a=4\\b=8\\c=3[/tex]

Then you can substitute these values into the Quadratic formula. Therefore, you get these solutions:

[tex]y=\frac{-8\±\sqrt{8^2-4(4)(3)} }{2(4)}[/tex]

[tex]y_1=-\frac{1}{2}\\\\y_2=-\frac{3}{2}[/tex]

Answer:

The solutions are y=-1/2 and y=-3/2

Step-by-step explanation:

Ok, for this problem we need to use the quadratic formula:

For [tex]ax^{2} +bx+c=0[/tex]

The values of x which are the solutions of the equation:

[tex]x=\frac{-b+-\sqrt{b^{2}-4ac}}{2a}[/tex]

In this case your variable is y, so:

[tex]ay^{2} +by+c=0[/tex]

[tex]y=\frac{-b+-\sqrt{b^{2}-4ac}}{2a}[/tex]

So, a=4, b=8 and c=3

[tex]y=\frac{-(8)+-\sqrt{(8)^{2}-4(4)(3) } }{2(4)}[/tex]

[tex]y=\frac{-(8)+-\sqrt{(16)}}{8}[/tex]

[tex]y=\frac{-8+4}{8}[/tex] and [tex]y=\frac{-8-4}{8}[/tex]

The solutions are

[tex]y=\frac{-1}{2}[/tex] and [tex]y=\frac{-3}{2}[/tex]

    f(x)⇒-∞ as x⇒-∞ and f(x)⇒∞ as x⇒∞

7. Length =x+10=8+10=18 inches

   Width=x=8 inches

Step by step explanation;

6. The graph represent an odd-degree polynomial function.

The graph enters the graphing box from the bottom and goes up leaving through the top of the graphing box.This is a positive polynomial whose limiting behavior is given by;

f(x)⇒-∞ as x⇒-∞ and f(x)⇒∞ as x⇒∞

7.

The area of a rectangle is given by l×w, where l is length and w is the width

Let=w=x  , l=x+10  and A=144 in² then;

l×w=144

(x+10) × x = 144

x²+10x =144......................complete squares on both sides

x²+10x+25=144+25

x²+10x+25=144+25................factorize

(x+5)²=169.......................square root the right-hand side

x+5= ±√169

x+5=±13.

x+5=13⇒⇒⇒x=8

x+5=-13⇒⇒⇒x= --18

x=8 inches....................value of width should be positive

Length =x+10=8+10=18 inches

Width=x=8 inches

Answer:

6. Since, by given graph,

The end behavior of the function f(x),

[tex]f(x)\rightarrow -\infty\text{ if }x\rightarrow -\infty[/tex]

[tex]f(x)\rightarrow +\infty\text{ if }x\rightarrow +\infty[/tex]

Thus, the function f(x) must has odd number of roots ( where the graph of a function intersects the x-axis )

⇒ The function must has odd number of solutions,

Again by the graph,

Graph of the function intersects the x-axis 5 times ( it touches the origin so it have the repeated root of x = 0 ),

Hence, the total number of real solution of f(x) is 5.

7. Let x represents the width of the rectangle( in inches ),

Given,

The length is 10 inches longer than the width,

⇒ Length of the rectangle = ( x + 10 ) inches

Thus, the area of the rectangle,

A = length × width = x(x+10)

According to the question,

A = 144 in²

⇒ x(x+ 10) = 144

[tex]x^2+10x=144[/tex]

[tex]x^2+10x-144=0[/tex]

[tex]x^2+18x-8x-144=0[/tex]  ( Middle term splitting )

[tex]x(x+18)-8(x+18)=0[/tex]

[tex](x+18)(x-8)=0[/tex]

⇒ x = -18 or x = 8    ( By zero test property )

The width can not be negative,

Hence, the width of the rectangle would be 8 inches.

EXPLANATION

The equation that expresses the approximate height h, in meters, of a ball t seconds after it is launched vertically upward from the ground is

[tex]h(t) = - 4.9 {t}^{2} + 25t[/tex]

To find the time when the ball hit the ground,we equate the function to zero.

[tex] - 4.9 {t}^{2} + 25t = 0[/tex]

Factor to obtain;

[tex]t( - 4.9t + 25) = 0[/tex]

Apply the zero product property to obtain,

[tex]t = 0 \: or \: \: - 4.9t + 25 = 0[/tex]

[tex]t = 0 \: \: or \: \: t = \frac{ - 25}{ - 4.9} [/tex]

t=0 or t=5.1 to the nearest tenth.

Therefore the ball hits the ground after approximately 5 seconds.

Answer:

The ball will hit the ground after 5 seconds ⇒ first answer

Step-by-step explanation:

* Lets study the information in the problem

- The ball is lunched vertically upward from the ground with an initial

  velocity 25 meters per second

- The ball will reach the maximum height when its velocity becomes 0

- The ball will fall down to reach the ground again

- The equation of the height (h), in meters of the ball t seconds after

  it is lunched from the ground is h = -4.9t² + 25t

- When the ball hit the ground again the height of it is equal 0

∵ h = 0

∴ 0 = -4.9t² + 25t ⇒ Multiply the two sides by -1 and reverse them

∴ 4.9t²  - 25t = 0 ⇒ factorize it by taking t as a common factor

∴ t(4.9t - 25) = 0 ⇒ equate each factor by 0

∵ t = 0 ⇒ the initial time when the ball is lunched

∵ 4.9t - 25 = 0 ⇒ add 25 to both sides

∴ 4.9t = 25 ⇒ divide each side by 4.9

∴ t = 5.102 ≅ 5 seconds

* The ball will hit the ground after 5 seconds

Answer:

y = 3x - 14

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = 3x - 4 is in this form with slope m = 3

• Parallel lines have equal slopes, hence

y = 3x + c ← is the partial equation of the parallel line

To find c substitute (4, - 2) into the partial equation

- 2 = 12 + c ⇒ c = - 2 - 12 = - 14

y = 3x - 14 ← equation of parallel line

The line that is parallel to y=3x-4 and passes through the point (4,-2) has the equation y=3x - 14. This is determined by knowing that parallel lines have the same slope and using the point-slope form of a line equation.

In Mathematics, two lines are parallel if they have the same slope. The line provided in this case is y=3x-4. The slope is 3, which we identify by taking the coefficient of x. Thus, any line parallel to this one will also have a slope of 3.

We also know the line we're seeking passes through the point (4,-2). We will use the point-slope form of a line equation, which is y - y1 = m(x - x1), where m is the slope, and (x1,y1) is a point on the line. Substituting the known values, we get: y - (-2) = 3(x - 4).

Simplifying this equation gives us the equation of the line that is parallel to y = 3x - 4 and passes through the point (4,-2) as: y = 3x -14.

Based on the analysis of the residual plots, Runner B's data is best fit by the regression line. This means that Runner B kept the most consistent pace throughout the race.

Analyze the residual plots to determine the best-fit regression line and identify the runner with the most consistent pace.

Observations from the Residual Plots:

- Runner A: The residual plot shows a clear U-shaped pattern, indicating a non-linear relationship and a poor fit for the regression line.

- Runner B: The residual plot exhibits a relatively random scatter of points around zero, suggesting a better fit for the regression line compared to Runner A.

- Runner C: The residual plot displays a distinct downward trend, also indicating a non-linear relationship and a poor fit for the regression line.

Conclusion:

Based on the analysis of the residual plots, Runner B's data is best fit by the regression line. This means that Runner B kept the most consistent pace throughout the race, as their actual pace closely aligned with the predicted pace from the linear model.

Therefore, the answer is B. Runner B.

The correct option is A. A. Runner A because if Runner A’s residual plot fits the criteria of a good linear fit.

To determine which runner kept the most consistent pace based on their residual plots, you need to understand the interpretation of residual plots in the context of linear regression.

Understanding Residual Plots

1. Residuals are the differences between the observed values and the values predicted by the regression line.

2. A residual plot displays these residuals on the vertical axis and the corresponding explanatory variable on the horizontal axis.

3.Consistency in Pace: For a runner to have a consistent pace, the residuals should be randomly scattered around zero with no discernible pattern. This indicates that the linear model is a good fit.

Interpreting Residual Plots

- Runner A: If the residuals for Runner A are randomly scattered around zero with no pattern, it means Runner A's data is well-fitted by the regression line, indicating a consistent pace.

- Runner B: If Runner B's residual plot shows a pattern (e.g., residuals increase or decrease systematically), it suggests that the regression line does not fit Runner B's data well, indicating inconsistency in pace.

- Runner C: Similarly, if Runner C's residual plot shows randomness around zero with no pattern, it means Runner C's data is well-fitted by the regression line, indicating a consistent pace.

Decision

Given the prompt, if you have residual plots for each runner:

1. Look for the plot with residuals randomly scattered around zero.

2. This runner’s data is best fit by the regression line and indicates the most consistent pace.

- Choose Runner A if Runner A’s residual plot shows randomly scattered residuals around zero.

- Choose Runner B if Runner B’s residual plot shows randomly scattered residuals around zero.

- Choose Runner C if Runner C’s residual plot shows randomly scattered

Since the question prompt explicitly mentions Runner A, the implication is that Runner A has the most consistent pace if their residual plot indeed shows a good fit with no pattern. Thus, based on the information given and assuming the residual plots for Runner A are the best fit, the answer would be:A. Runner A

The complete questionis:

Three runners competed in a race. Data were collected at each mile mark for each runner. If the runner ran at a constant pace, the data would be linear. A regression line was fitted to their data. Use the residual plots to decide which data set is best fit by the regression line, and then identify the runner that kept the most consistent pace.

A. Runner A

B. Runner B

C. Runner C

We can rewrite the equation of the circle as

[tex](x-0)^2+(y-0)^2=10^2[/tex]

so that we can be in the form

[tex](x-h)^2+(y-k)^2=r^2[/tex]

When you write the equation of a circle in this form, then the center is [tex](h,k)[/tex] and the radius is [tex]r[/tex].

So, in our case, the radius of the circle is 10.

To find the length of the bridge, we find the two points where the bridge crosses the lake (i.e. we solve the system between the equations of the line and the circle), and compute the distance between those points:

[tex]\begin{cases}y=x+2\\x^2+y^2=100\end{cases}\implies\begin{cases}y=x+2\\x^2+(x+2)^2=100\end{cases}[/tex]

Solving the second equation for x, we have

[tex]x^2+(x+2)^2=100 \iff x^2+x^2+4x+4=100\iff\\2x^2+4x-96=0 \iff x^2+2x-48=0\\\iff x=-8\ \lor\ x=6[/tex]

We use the first equation to compute the correspondent values of y:

[tex]x=-8\implies y=x+2=-6 \implies P_1 = (-8,-6)[/tex]

[tex]x=6\implies y=x+2=8 \implies P_1 = (6,8)[/tex]

Now, the distance between these two points is given by the pythagorean's theorem:

[tex]d = \sqrt{(-8+6)^2+(-6+8)^2} = \sqrt{4+4}=2\sqrt{2}[/tex]

The radius of the lake is 10 units. The length of the bridge is 14√2 units. We found this by solving the equations of the circle and the line representing the bridge.

The equation of the circular lake is given as  [tex]x^2 + y^2 = 100[/tex] . This equation is of the form  [tex](x -b)^2 + (y - c)^2 = r^2,[/tex] where the center of circle is at (b, c) and the radius is r. In this case, the center is at (0, 0), and the radius squared is 100. Therefore, the radius (r) is:

r = √100 = 10

So, the radius of the lake is 10 units.

The bridge is represented by the function y - x = 2, which can be rewritten as y = x + 2.

To find the points of intersection between this line and the circle, substitute y = x + 2 into the circle's equation  

[tex]x^2 +[/tex][tex]y^2 = 100:[/tex]

[tex]x^2 + (x + 2)^2 = 100[/tex]

Simplify this to:

[tex]x^2 + x^2 + 4x + 4 = 100[/tex]

[tex]2x^2 + 4x + 4 = 100[/tex]

[tex]2x^2 + 4x - 96 = 0[/tex]

Divide everything by 2:

[tex]x^2 + 2x - 48 = 0[/tex]

To solve this quadratic equation, use the quadratic formula x = (-b ± √([tex]b^2[/tex] - 4ac))/(2a), where a = 1, b = 2, and c = -48:

x = (-2 ± √([tex]2^2[/tex] - 4*1*(-48)))/(2*1)

x = (-2 ± √(4 + 192))/2

x = (-2 ± √196)/2

x = (-2 ± 14)/2

This results in two solutions:

x = (12)/2 = 6

x = (-16)/2 = -8

Thus, the points of intersection are (6, 8) and (-8, -6).

Finally, to find the length of the bridge, calculate the distance between these two points using the distance formula: d = [tex]\sqrt{ ((x2 - x1)^2 + (y2 - y1)^2)[/tex]

[tex]d = \sqrt{((6 - (-8))^2 + (8 - (-6))^2)[/tex]

[tex]d = \sqrt{((6 + 8)^2 + (8 + 6)^2)[/tex]

d = [tex]\sqrt{(14^2 + 14^2)[/tex]

d = [tex]\sqrt{(196 + 196)[/tex]

[tex]d = 14\sqrt{2}[/tex]

Therefore, the length of the bridge is [tex]14\sqrt{2}[/tex] units.

Answer:

• 800 pavilion seats

• 800 lawn seats

Step-by-step explanation:

Let p represent the number of pavilion seats sold. Then 1600-p is the number of lawn seats sold. Total revenue is ...

25p +20(1600 -p) = 36000

5p + 32000 = 36000

5p = 4000

p = 800 . . . . . . . . . . number of pavilion seats sold

1600-p = 800 . . . . . number of lawn seats sold

_____

You can work these problems in your head. Consider that all seats were sold at the lower price. Then revenue would be 1600·20 = 32000. It was 36000 -32000 = 4000 more than that. The difference in ticket price is 25 -20 = 5 dollars, so there must have been 4000/5 = 800 higher-priced tickets sold. (Compare this working to the math above. You will find it substantially similar.)

The horizontal cross-sections of the pyramid and the cone at the same height must have the same area.

Step-by-step explanation:

We are given that a pyramid and a cone are both 10 centimeters tall and have the same volume and we are to determine a statement which must be true for both the solids.

The horizontal cross-sections of the pyramid and cone at the same height must have the same area.

This is because

Answer:

Tbase area is same for both pyramid and cone

And cross section at same height the cross sectional area is same

Step-by-step explanation:

Points to remember

Volume of pyramid = (a²h)/3

Where a -  side of base

h - height of pyramid

Volume of cone = (πr²h)/3

Where r - Radius of cone and

h - Height of cone

To find the correct answer

We have height of pyramid and cone is 10 cm

(a²h)/3 = (πr²h)/3

(a² * 10)/3 = (πr² * 10)/3

10a² = 10πr²

From this we get base area is same for both pyramid and cone

And cross section at same height the cross sectional area is same

One-fourth of x is represented by x/4.
Now, we take one-third of that amount, which means we multiply (x/4) by 1/3, giving us (x/4) * (1/3).
Finally, we take one-sixth of the result from the previous step, so we then multiply by 1/6, yielding (x/4) * (1/3) * (1/6).
The expression we have is:
(x/4) * (1/3) * (1/6) = 5
To solve for x, we must clear the fractions by performing the multiplications:
(x/4) * (1/3) * (1/6) can be simplified before we do anything else:
* 1 * 1 = x
--
4 * 3 * 6   72
So we have:
x/72 = 5
To solve for x, multiply both sides of the equation by 72:
x = 5 * 72
Now, let's do the multiplication:
x = 360
Therefore, one-sixth of one-third of one-fourth of 360 is equal to five.

Answer:

∠C and ∠R

Step-by-step explanation:

The ASA postulate represents angle / side / angle

where the included side is the side between the vertices of the two angles.

∠H and ∠I and the sides HC and IR are the AS

The required angles would be ∠C and ∠R for ASA

Answer:

The mean of the worker's salary would be $26,667

The standard deviation is $2915.43

Step-by-step explanation:

Add the salaries together and divide by the number of workers for the mean

Use the formula for standard deviation s=√∑(x¹-x⁻)²/n-1

Answer:

The teacher can hand out pizza to 8 students.

Step-by-step explanation:

To find how many slices of pizza the teacher can hand out , you can divide 7 by 7/8 and round down the nearest whole number.

7 ÷ 7/8 = 8

8 is already a whole number. No need to round down.

The teacher can hand out pizza to 8 students.

Answer is 8 students

N= 7/(7/8)

N= (7*8)/7

N= 56/7

N= 8
