Find the altitude of a triangle whose area is 100 cm² and whose base is 20 cm.
Altitude = Cm.

Answers

Answer 1

Answer:

altitude = 10 cm

Step-by-step explanation:

Finding the altitude of triangle when area and base is given:

         [tex]\sf \boxed{\text{\bf Area of triangle = $\dfrac{1}{2}*base*altitude$}}[/tex]

                               base = 20 cm

          Area of a triangle = 100 sq.cm

               [tex]\sf \dfrac{1}{2}*20*altitude = 100\\\\\\[/tex]

                   10 * altitude = 100      

                          altitude = 100 ÷ 10

                         altitude = 10 cm

Answer:

8

Step-by-step explanation:

To solve this, you can add 2/5 b to both sides of the equation. You now have 3 + 5/5 (or 1) b = 11. => 3 + b = 11 => Now, subtract 3 from both sides, and you have b = 11 - 3, and then b = 8.

Step-by-step explanation:

3 + 2/5 b =11 - 2/5 b (this is the given question is it?)

2/5 b + 2/5 b= 11 - 3 (like terms together, you transpose -2/5b to the other side as shown.)

2b+2b = 8 ( at that stage you would find t

5 hat 5 is the common value to go into 5 itself, as shown.

4b = 8 ( you just add 2b + 2b to have 4b)

4b = 8 × 5 ( simple math as shown)

4b = 40 ( you multiply 8 × 5 to obtain 40)

Which equation represents the line that is perpendicular to graph of 4x+3y=9 and passes through (-2,3)

Answers

Final answer:

The equation of the line which is perpendicular to the line 4x + 3y = 9 and passes through the point (-2,3) is y = 3/4x + 4.5.

Explanation:

The original equation is 4x + 3y = 9. To start off, rewrite this equation in slope-intercept form (y = mx + b) to help find the slope. After isolating y, the equation turns into y = -4/3x + 3. So, the slope of the original line is -4/3.

Perpendicular lines have slopes which are negative reciprocals of each other, thus the slope of the line perpendicular to the given line is the negative reciprocal of -4/3, which is 3/4 (m = 3/4 for the second line)

We are also given that the line we are looking for passes through the point (-2,3). Use the point-slope form of a line, given by y - y1 = m(x - x1), where m is the slope, and (x1, y1) is the given point. Substituting in the values, you get:

y - 3 = 3/4(x - -2).

Simplifying the equation, we find that the line perpendicular to 4x + 3y = 9 and passing through (-2, 3) is y = 3/4x + 4.5

Sphere radius 7 inches what's the volume

Answers

Answer:

The volume of sphere is 1436.03 inches³.

Step-by-step explanation:

Given:

The radius of sphere = 7 inches.

Now, to find the volume.

So, to get the volume we put the formula:

[tex]Volume=\frac{4}{3} \pi r^3[/tex]

Taking the value of π = 3.14

[tex]Volume=\frac{4}{3}\times 3.14\times {7}^3[/tex]

[tex]Volume=\frac{4}{3}\times 3.14\times 343[/tex]

[tex]Volume=\frac{4}{3}\times 1077.02[/tex]

[tex]Volume=\frac{4308.08}{3}[/tex]

[tex]Volume=1436.03\ inches^3[/tex]

Therefore, the volume of sphere is 1436.03 inches³.

Step-by-step explanation: To find the volume of the sphere, start with the formula for the volume of a sphere.

Volume = [tex]\frac{4}{3} \pi r^{3}[/tex]

Notice that our sphere has a radius of 7 inches so plugging into the formula, we have [tex](\frac{4}{3})(\pi)(7 in.)^{3}[/tex].

Start by simplifying the exponent. (7 in.)³ is equal to 7 inches x 7 inches x 7 inches or 343 in³ so we have [tex](\frac{4}{3}) (343 in.^{3})(\pi)[/tex].

Next, 4 x 343 is 1,372 which gives us [tex]\frac{1,372\pi }{3}[/tex]. Notice that 1,372 doesn't divide by 3 so this is our final answer for the volume of the sphere.

The function f is such that f(x) = x^2 – 2x + 3
Solve f(x) = 27

(The bottom question in the photo)

Answers

Answer:

x = - 4, x = 6

Step-by-step explanation:

Given

f(x) = x² - 2x + 3 and f(x) = 27, then equating the 2 gives

x² - 2x + 3 = 27 ( subtract 27 from both sides )

x² - 2x - 24 = 0 ← in standard form

Consider the factors of the constant term (- 24) which sum to give the coefficient of the x- term (- 2)

The factors are - 6 and + 4, since

- 6 × 4 = - 24 and - 6 + 4 = - 2, thus

(x - 6)(x + 4) = 0

Equate each factor to zero and solve for x

x - 6 = 0 ⇒ x = 6

x + 4 = 0 ⇒ x = - 4

f(x)= 27

x^2 -2x+3=27

×^-2x+3-27=0

x^2x-24=0

(x-6)(x-4)=0

Option B is correct. The required composite function where f(g(x)) is x is f (x) = StartFraction 2 Over x EndFraction and g (x) = StartFraction 2 Over x EndFraction

Composite functions are functions written inside another function e.g f(g(x))

Given the expressions

f(x) = 2/x

g(x) = 2/x

We are to find the composite function f(g(x))

f(g(x)) = f(2/x)

f(2/x) =  (2/(2/x))

f(2/x)  = 2 * x/2

f(2/x) = x

Hence the required composite function where f(g(x)) is x is f (x) = StartFraction 2 Over x EndFraction and g (x) = StartFraction 2 Over x EndFraction

[tex]1. \( (f \circ g)(x) = \frac{1}{x^2} \)\\2. \( (f \circ g)(x) = x \)\\3. \( (f \circ g)(x) = -x \)\\4. \( (f \circ g)(x) = \frac{1}{4}x - 1 \)[/tex]

let's break down each pair of functions and find their composition:

1. For [tex]\( f(x) = x^2 \) and \( g(x) = \frac{1}{x} \):[/tex]

  To find [tex]\( (f \circ g)(x) \)[/tex], we substitute [tex]\( g(x) \) into \( f(x) \):[/tex]

  [tex]\[ (f \circ g)(x) = f(g(x)) = f\left(\frac{1}{x}\right) = \left(\frac{1}{x}\right)^2 = \frac{1}{x^2} \][/tex]

  So, [tex]\( (f \circ g)(x) = \frac{1}{x^2} \).[/tex]

2. For [tex]\( f(x) = \frac{2}{x} \) and \( g(x) = \frac{2}{x} \):[/tex]

  Here, [tex]\( (f \circ g)(x) = f(g(x)) = f\left(\frac{2}{x}\right) \).[/tex]

  When you substitute [tex]\( \frac{2}{x} \) into \( f(x) \),[/tex]  you get:

 [tex]\[ (f \circ g)(x) = f\left(\frac{2}{x}\right) = \frac{2}{\frac{2}{x}} = x \][/tex]

  So, [tex]\( (f \circ g)(x) = x \).[/tex]

3. For [tex]\( f(x) = \frac{x-2}{3} \) and \( g(x) = 2 - 3x \):[/tex]

 [tex]\( (f \circ g)(x) = f(g(x)) = f(2 - 3x) \).[/tex]

  Substituting  [tex]\( 2 - 3x \) into \( f(x) \),[/tex]we get:

 [tex]\[ (f \circ g)(x) = f(2 - 3x) = \frac{(2 - 3x) - 2}{3} = \frac{-3x}{3} = -x \][/tex]

  So, [tex]\( (f \circ g)(x) = -x \).[/tex]

4. For [tex]\( f(x) = \frac{1}{2}x - 2 \) and \( g(x) = \frac{1}{2}x + 2 \):[/tex]

  Here, [tex]\( (f \circ g)(x) = f(g(x)) = f\left(\frac{1}{2}x + 2\right) \).[/tex]

  When you substitute [tex]\( \frac{1}{2}x + 2 \) into \( f(x) \),[/tex] you get:

 [tex]\[ (f \circ g)(x) = f\left(\frac{1}{2}x + 2\right) = \frac{1}{2}\left(\frac{1}{2}x + 2\right) - 2 = \frac{1}{4}x + 1 - 2 = \frac{1}{4}x - 1 \][/tex]

  So, [tex]\( (f \circ g)(x) = \frac{1}{4}x - 1 \).[/tex]

So, summarizing:

1. For [tex]\( f(x) = x^2 \) and \( g(x) = \frac{1}{x} \), \( (f \circ g)(x) = \frac{1}{x^2} \).[/tex]

2. For [tex]\( f(x) = \frac{2}{x} \) and \( g(x) = \frac{2}{x} \), \( (f \circ g)(x) = x \).[/tex]

3. For [tex]\( f(x) = \frac{x-2}{3} \) and \( g(x) = 2 - 3x \), \( (f \circ g)(x) = -x \).[/tex]

Find the equation of the image of a line y=3x-8 after reflection over the x-axis

Answers

Answer:

The required image line is 3x + y = 8

Step-by-step explanation:

We have to find two points on the given straight line then find their reflection points over the x-axis and then finally the straight line passing through those two image points will give the required straight line.

Now, the given straight line is y = 3x - 8.

Now, two any points on this straight line are say (1,-5) and (2,-2).

So, the image of (1,-5) point reflecting over the x-axis will be (1,5) and the image of the point (2,-2) reflecting over the x-axis will be (2,2).

Therefore, the straight line passing through those two image points will have equation  

[tex]\frac{y - 5}{5 - 2} = \frac{x - 1}{1 - 2}[/tex]

⇒ y - 5 = 3(1 - x)

A bicycle wheel with the diameter 70cm is making 25 revolutions while travelling. Find the distance covered by the bicycle

Answers

Final answer:

The total distance covered by the bicycle is calculated using the circumference of the wheel and the number of revolutions made. With a wheel diameter of 70 cm, the total distance comes to approximately 55.0 meters after 25 revolutions.

Explanation:

The question involves calculating the distance covered by a bicycle wheel making a certain number of revolutions. Given that the diameter of the wheel is 70 cm, we can find the circumference, which is the distance the wheel covers per revolution. The circumference is equal to \\(\pi\cdot d\\), where \\(d\\) is the diameter. Substituting the given diameter:

Circumference = \\(\pi \times 70 \\text{cm}\\)

Since the wheel makes 25 revolutions, the total distance covered (\\em{D}}) can be found by multiplying the circumference by the number of revolutions:

Total distance covered = Circumference \\(\times\\) Number of revolutionsTotal distance covered = \\(\pi \times 70 \\text{cm} \times 25\\)

Thus, the bicycle covers a distance of \\(25 \times \pi \times 70 \\text{cm}\\), or \\(25 \times \pi \times 0.7 \\text{m}\\), since 100 cm equals 1 meter.

To find the exact value, you would calculate:

Total distance covered = \\(25 \times \pi \times 0.7 \\text{m} \\approx 55.0 \\text{meters}\\)

$13,957 is invested, part at 7% and the rest at 6%. If the interest earned from the amount invested at 7% exceeds the interest earned from the amount invested at 6% by $833.73, how much is invested at each rate?

Answers

Answer:

The Amount invested at 7% interest is $12,855

The Amount invested at 6% interest = $1,102  

Step-by-step explanation:

Given as :

The Total money invested = $13,957

Let The money invested at 7% = [tex]p_1[/tex]  = $A

And The money invested at 6% = [tex]p_2[/tex] = $13957 - $A

Let The interest earn at 7% = [tex]I_1[/tex]

And The interest earn at 6% = [tex]I_2[/tex]

[tex]I_1[/tex] -  [tex]I_2[/tex] = $833.73

Let The time period = 1 year

Now, From Simple Interest method

Simple Interest = [tex]\dfrac{\textrm principal\times \textrm rate\times \textrm time}{100}[/tex]

Or,  [tex]I_1[/tex] = [tex]\dfrac{\textrm p_1\times \textrm 7\times \textrm 1}{100}[/tex]

Or,  [tex]I_1[/tex] = [tex]\dfrac{\textrm A\times \textrm 7\times \textrm 1}{100}[/tex]

And

[tex]I_2[/tex] = [tex]\dfrac{\textrm p_2\times \textrm 6\times \textrm 1}{100}[/tex]

Or,  [tex]I_2[/tex] = [tex]\dfrac{\textrm (13,957 - A)\times \textrm 6\times \textrm 1}{100}[/tex]

∵  [tex]I_1[/tex] -  [tex]I_2[/tex] = $833.73

So, [tex]\dfrac{\textrm A\times \textrm 7\times \textrm 1}{100}[/tex] -  [tex]\dfrac{\textrm (13,957 - A)\times \textrm 6\times \textrm 1}{100}[/tex] = $833.73

Or, 7 A - 6 (13,957 - A) = $833.73 × 100

Or, 7 A - $83,742 + 6 A = $83373

Or, 13 A = $83373 + $83742

Or, 13 A = $167,115

∴ A = [tex]\dfrac{167115}{13}[/tex]

i.e A = $12,855

So, The Amount invested at 7% interest = A = $12,855

And The Amount invested at 6% interest = ($13,957 - A) = $13,957 - $12,855

I.e The Amount invested at 6% interest = $1,102

Hence,The Amount invested at 7% interest is $12,855

And The Amount invested at 6% interest = $1,102   . Answer

Final answer:

The total amount invested and the difference in interest earned. Then, using algebraic techniques such as substitution or elimination, we solve for the amounts invested at 7% and at 6%.

Explanation:

To solve the problem of allocating investments at different interest rates, we can set up a system of equations. Let's designate x as the amount invested at 7% and y as the amount invested at 6%. Given the total investment is $13,957, our first equation will be:

x + y = 13,957 (1)

The interest from the amount invested at 7% exceeds the interest from the amount invested at 6% by $833.73. The second equation, reflecting the interest earned, will be:

0.07x - 0.06y = 833.73 (2)

y = 13,957 - x (3)

Now, substitute equation (3) into equation (2) and solve for x:

0.07x - 0.06(13,957 - x) = 833.73

Simplify and solve this equation to find the value of x.
Once we have the value for x, we can use equation (3) to find the corresponding value for y, giving us the amount invested at each interest rate.

Interior angles of a rhombus always add up to 360 degrees. Thus we can set up an equation:

g+g+2g+2g=360

Now let's combine all the like terms (g's).

6g=360

Now we divide both sides by six to isolate g.

g=60

We can now substitute g into angle B, to find its value.  

2g

2(60)

120

Thus, the measure of angle B is 120, or option D.

John is selling candy bars the equation is p=c^2+2c-5 determines the profit,p, where c is the number of candy bars sold what is the minimum number of candy bars he needs to sell to make profit

Answers

Answer:

2

Step-by-step explanation:

Find the value of c where p = 0.

0 = c² + 2c − 5

6 = c² + 2c + 1

6 = (c + 1)²

±√6 = c + 1

c = -1 ± √6

c must be positive, so c = -1 + √6 ≈ 1.45.  So John must sell at least 2 candy bars to make a profit.

We can also show this using trial and error.

If c = 0, then p = -5

If c = 1, then p = -2

If c = 2, then p = 3

Answer:

∠2 = 78°

Step-by-step explanation:

Angle of a straight line is 180°.

So, that would mean ∠1 + ∠2 = 180°.

⇒ ∠2 = 180° - ∠1

⇒ ∠2 = 180° - 102°

∠2 = 78°

Hence, the answer.

A boat rental charges $7.50 for the first hour and $2 for each additional hour. Which rule gives the cost for x hours of renting a boat?

Answers

c = 7.50 + 2(x - 1) is the rule that gives cost for "x" hours of renting a boat

Solution:

Given that a boat rental charges $7.50 for the first hour and $2 for each additional hour.

To find: Rule that gives the cost for x hours of renting a boat

Let "x" be the total hours of renting a boat

[tex]c = f + (v \times x - 1)[/tex]

"c" is the total cost for the boat rent

"f" is the fixed cost for boat rent for first hour

"v"  is the cost for each additional hours of rent

"x" is the total hours of renting a boat

In the expression we have used "x - 1" to represent the additional hour of boat rent after first hour

Here f = $ 7.50

v = $ 2

[tex]c = 7.50 + 2 \times x - 1\\\\c = 7.50 + 2(x - 1)[/tex]

Thus c = 7.50 + 2(x - 1) is the rule that gives cost for "x" hours of renting a boat

Final answer:

The cost for renting a boat for x hours can be found using the formula y = 7.50 + 2(x - 1), where y is the total cost and x is the number of hours.

Explanation:

Based on the given information, the boat rental company charges $7.50 for the first hour and then an additional $2 for each subsequent hour. Therefore, if x is the number of hours you rent the boat, the total cost would be calculated using the formula y = 7.50 + 2(x - 1). Here, y represents the total cost of renting the boat for x hours. The formula subtracts the one-hour charge included in the initial payment.

the sum of three numbers is 50 the second number is three times the first number and the third number is twice the second number what are the numbers​

Answers

Answer:1st is 5 2nd is 15 last is 30

Step-by-step explanation:

1st = 5

2nd = 3 x 5 = 15

3rd = 15 x 2 = 30

5 + 15 + 30 = 50

Final answer:

The three numbers in question are 5, 15, and 30. This has been achieved by setting up and solving algebraic equations based on the given conditions.

Explanation:

To solve this problem, we should set up equations based on the information given. Let's define:
First number = x
Second number = 3x (since it is three times the first number)
Third number = 2 * 3x = 6x (since it is twice the second number)

According to the problem, the sum of these three numbers is 50. Therefore, we can write the equation as:
x + 3x + 6x = 50

Solve for x:
10x = 50
x = 50 / 10 = 5

So, the three numbers are:
First number = x = 5
Second number = 3x = 3 * 5 = 15
Third number = 6x = 6 * 5 = 30

Kim drove from Mathtown at (-2, 5) to Geometryville at (3, -1) to Algebra Springs at (-6, -5), and then back to Mathtown. Find the total distance Kim traveled to the nearest hundredth.

Answers

Answer:

33.38 km

Step-by-step explanation:

Kim drove from Math Town at (-2, 5) to Geometry Ville at (3, -1) to Algebra Springs at (-6, -5), and then back to Math town.

Now, the distance from (-2,5) point to (3,-1) point will be  

[tex]\sqrt{(- 2 - 3)^{2} + (5 - (-1))^{2}} = \sqrt{61}[/tex] km.

Again, the distance from point (3,-1) and (-6,-5) point will be  

[tex]\sqrt{(3 - (- 5))^{2} + (- 1 - (- 5))^{2}} = \sqrt{80}[/tex] km.

Therefore, the total distance Kim traveled will be = [tex]2(\sqrt{61} + \sqrt{80}) = 33.38[/tex] Km. (Answer)

The distance between two points [tex](x_{1},y_{1})[/tex] and [tex](x_{2},y_{2})[/tex] on the coordinate plane is given by

Step-by-step explanation:

Let x represent the number of days , then

(1) The exponential function to represent the spread of Ben's social media spread implies :

f(x) = 2([tex]3^{x}[/tex])

(2) The exponential function that represent carter;s social media spread implies

f(x) = 10([tex]2^{3}[/tex]

(3) the graph of the three functions is attached below

color red graph represents  Ben's social media spread , the graph with color blue represents Carter;s social media spread and the graph with green color represents Amber's social media spread

(4) on the 3rd day

Amber will receive 192 shares .

The equation for the spread of his shares is

f(x) = 3([tex]4^{x}[/tex]

where x is the number of days , so we have

3([tex]4^{3}[/tex])

= 3 ( 64)

= 192 shares

Ben's shares on the 3rd day will be

f(x) = 2([tex]3^{x}[/tex] )

= 2([tex]3^{3}[/tex])

= 2 ( 27)

= 54

Therefore , Ben will have 54 shares on the third day

Carter's share on the third day

f(x) = 10 ( [tex]2^{x}[/tex] )

= 10 ([tex]2^{3}[/tex] )

= 10 (8)

= 80

Therefore , Carter will receive 80 shares on the 3rd day
