Answer:

  (d -21) is the number of days the book is late

Step-by-step explanation:

There is no fee if the book is returned within 21 days, so d-21 represents the number of "late days" for which a fee is charged.

Answer:

(d -21) is the number of days the book is late

Answer:

  6 yards by 11 yards

Step-by-step explanation:

Factors of 66 are ...

  66 = 1·66 = 2·33 = 3·22 = 6·11

The last pair of factors differ by 5, so represent the solution to the problem.

The width of the parking lot is 6 yards; the length is 11 yards.

Final answer:

The parking lot's dimensions are found by setting a quadratic equation w × (w + 5) = 66 based on its area. Solving for w, the width is 6 yards, hence the length is 11 yards, making the dimensions 6 yards by 11 yards.

Explanation:

To find the dimensions of the parking lot when the length is 5 yards more than the width and the area is 66 square yards, we can set up an equation based on the area of a rectangle (area = length × width). We can define the width as w and the length as w + 5 since the length is 5 yards more than the width.

The equation representing the area will then be:

w × (w + 5) = 66

Solving this quadratic equation (w^2 + 5w - 66 = 0) by factoring or using the quadratic formula, we find that w = 6 or w = -11. We discard the negative value since a width cannot be negative, so the width is 6 yards and the length is 11 yards (since it's 5 yards more than the width).

Therefore, the dimensions of the parking lot are 6 yards by 11 yards.

Answer:

  D.  (x-5)^2 = 36

Step-by-step explanation:

If you add 11 to the given equation, you get ...

  x^2 -10x = 11

Then you can add the square of half the x-coefficient to complete the square.

  x^2 -10x +25 = 11 +25

  (x -5)^2 = 36 . . . . simplify to the appropriate form

Answer:

Step-by-step explanation:

No solution means that the 2 lines will never intersect in a coordinate plane.  The only kinds of lines that can exist within the same coordinate plane and never intersect are lines that are parallel.  The slopes have to be the same for lines to be parallel.  The y-intercept, or where they go through the y axis, won't be the same, but the value of the slope has to be.  The slope of the equation on the right is 33, so if these lines are parallel, then Q has to equal 33.  P can then be any real number NOT equal to 25.

Answer:

x = 3.1 ft

Step-by-step explanation:

Use Pythagoras' Theorem to find the base of the triangle. The base of the triangle is half of 'x'. Let's call the base 'y' for now.

To find 'y' we must use this formula,

[tex]y^{2} = c^{2} -b^{2}[/tex]

'c' is the hypotenuse, the longer side, and 'b' is the other short side.

Sub in the numbers for 'c' and 'b',

[tex]y^{2} = 2.1^{2} -1.4^{2}[/tex]

               = 2.45

Square root both sides to get 'y' by itself,

y = 1.5652.....

Remember that 'y' is half of x? Simply multiply 'y' by 2 to get an answer for 'x',

x = 1.5652.... x 2

  = 3.1 ft (1 d.p. nearest tenth)

Answer:

The correct answer is B. The number of rides and the total cost are both dependent variables, as both depend on the amount of money that Nia has.

Step-by-step explanation:

Both the number of rides and the total cost are variables that depend on the amount of money that Nia has. This is so because the passage has a cost, and that cost can not exceed the amount of money that Nia has, because if she exceeds her $ 19.50 she won't be able to pay the ticket. Then, Nia has a possible amount of 26 rides as maximum (19.5 / 0.75 = 26), and the maximum total cost that can be paid is $ 19.50.

Final answer:

The correct answer is: C) The number of rides is the independent variable, and the total cost is the dependent variable.

Explanation:

In the scenario where Nia has $19.50 to ride the subway around New York, at a cost of $0.75 per ride, the correct identification of the dependent and independent variables is crucial for understanding the relationship between these quantities.

The independent variable is the number of rides Nia can take. This is because it is the variable over which we have control or can set at different levels; in other words, Nia decides how many trips she takes.

The dependent variable is the total cost of these rides. The cost depends on how many rides she takes, changing accordingly with that number.

Therefore, the correct answer is: C) The number of rides is the independent variable, and the total cost is the dependent variable.

[tex]x \ge 10,000[/tex].

Step-by-step explanation:

What's the total income of Ms. Wolf in a year?

The annual income of Ms. Wolf comes in two parts:

How many commission does Ms. Wolf receive for each share she sold? [tex]\$\;50 \times 4\% = \$\;50 \times 0.04 = \$\;2[/tex].

Let the number of shares that Ms. Wolf sold be [tex]x[/tex]. Ms. Wolf will receive a commission of [tex]\$\;2x[/tex].

Total annual income of Ms. Wolf: [tex]\$\; (50,000 + 2x)[/tex].

The phrase "at least" indicates that [tex]\$\; (50,000 + 2x)[/tex] shall be greater than or equal to $70,000. That is:

[tex]\$\; (50,000 + 2x)\ge \$\;70,000[/tex].

[tex]2x + 50,000 \ge 70,000[/tex].

[tex]x \ge 20,000[/tex].

Answer:

Cost of yard silk fabric : $35

Cost of yard of woolen fabric: $60

Step-by-step explanation:

This problem must be represented as a linear system of equations

Let

x = the cost of 1 yard of woolen fabric

y = the cost of 1 yard of silk fabric

The problem tells us

4 yards of woolen fabric costs $30.00 more than 6 yards of silk fabric.

4.x = 6.y + 30

cost of the silk is $25.00 less than the cost of the wool

y = x - 25

The system of equations is

4x - 6y =  30

x - y  = 25

If we solve this system of equations using a calculator or computational tool, we get the following values

x = $60

y = $35

Answer:

  = (x +4)(x -7)(x^2 +25)

  roots are -4, 7, ±5i

Step-by-step explanation:

You have not said what "solve" means in this context. An expression by itself doesn't have a solution. We have assumed you want to find the factoring and/or roots of it.

I like to use a graphing calculator to find the real roots. For this expression, there are two of them, one positive and one negative. (You know there will be one positive real root, and at least one negative real root, from Descartes's rule of signs.)

Then those roots can be factored out and the solution to the remaining quadratic determined. That factoring can occur by polynomial long division, synthetic division, or other means.

I like to see what happens when I plot the graph of the function divided by the known factors. (We expect a parabola that doesn't cross the x-axis.) The vertex of that parabola can be used to find the remaining roots.

The x-intercepts of the given expression are -4 and +7, so two of the factors are (x+4) and (x-7). Dividing these from the given expression (by synthetic division or other means) gives (x^2 +25). This only has imaginary roots (±5i).

____

If you're constrained to doing this "by hand" with only a scientific calculator, Descartes's rule of signs tells you there is one positive real root. (Only one sign change in the sequence of coefficient signs: +----.)

The rational root theorem tells you it will be a divisor of 700. Various estimates of the maximum magnitude of it will tell you it is probably less than 14 (easily checked). So, the numbers you can test as roots would be 1, 2, 4, 5, 7, 10, 14. You will find that 7 is a root, and then you can reduce the problem to the cubic x^3 +4x^2 +25x +100.

When odd-degree term signs are changed, there will be 3 sign changes (-+-+), hence at least one negative real root. The rational root theorem tells you it is a divisor of 100, so possible choices are -1, -2, -4, -5. By trial and error or other means, you can find the root to be -4. Then the problem reduces to the quadratic x^2 +25.

Roots of that are ±√(-25) = ±5i.

This process generally entails a fair amount of trial-and-error work, which is why I prefer one that makes some use of technology.

Answer:

center at (6, -4) r = √7

Step-by-step explanation:

(x – 6)^2 + (y + 4)^2 = 7

This is in the form

(x – h)^2 + (y - k)^2 = r^2

Where (h,k) is the center of the circle and r is the radius of the circle

Rearranging the equation to match this form

(x – 6)^2 + (y -- 4)^2 = sqrt(7) ^2

The center is at (6, -4) and the radius is the sqrt(7)

Answer:

Answer:

13/18

Step-by-step explanation:

We need to get a common denominator for 9,6,3

That would be 18

5/9 *2/2 = 10/18

5/6 * 3/3 = 15/18

2/3 *6/6 = 12/18

5/9+5/6 = 10/18 +15/18 = 25/18

Then

25/18 - 2/3 = 25/18 - 12/18 = 13/18

Answer:

[tex]x =26\°[/tex]

Step-by-step explanation:

For this case we have 2 secant lines and an exterior angle x.

Then by definition the measure of the outer angle is equal to half the difference of the arcs formed by the sides.

This means that the angle x is equal to:

[tex]x =\frac{66\°-14\°}{2}\\\\x =26\°[/tex]

the answer is:

[tex]x =26\°[/tex]

Area of a triangle = height x base ÷ 2

When ever you have an isosceles triangle, remember that you can split it in half to form two right angled triangles - which allow you to use Pythagoras' Theorem.

So we split 10cm in half to get 5cm.

We can then use 13cm and 5cm to work out the height:

Height = √(13²  - 5²)      (Note: you subtract because you are using the    

           = √144              (hypotenuse)

           =  12

---------------------------------------------------------

Now to get the area, we just multiply the base (which is 10) by the height (which is 12) and divide by 2:

Area = 12 x 10 ÷ 2

        = 6 x 10               (note: 12 ÷ 2 = 6 )

        = 60 cm²

Answer:

c(x) = –8x^2 + 3x – 5 is a quadratic function.

Step-by-step explanation:

At first, we will define what a quadratic function is.

A quadratic function is a polynomial with one or more variables with degree 2.

So, from the given functions

a(x) = -2x^3+ 2x – 6 has highest degree 3. So it is not a quadratic function.

b(x)=5x^3 + 8x^2 + 3 has highest degree 3. So it is not a quadratic function.

c(x) = –8x^2 + 3x – 5 has highest degree 2. So it is a quadratic function.

d(x) = 6x^4 + 2x – 3 has highest degree 4. So it is not a quadratic function.

Answer:

x = 34

Step-by-step explanation:

The 3 given angles form a straight angle and sum to 180°, hence

x + 12 + 100 + x = 180

2x + 112 = 180 ( subtract 112 from both sides )

2x = 68 ( divide both sides by 2 )

x = 34

Answer:

x=34

Step-by-step explanation:

Alright.

x+12+100+x=180

         2x+112=180

                2x=68

                   x=34

The answers are:

[tex]MaximumDistance=1200.1ft\\MinimumDistance=1199.9ft[/tex]

Since we are given the margin of error and it's equal to ±0.1 feet, and we know the surveyed distance, we can calculate the maximum and minimum distance. We must remember that margin of errors usually involves and maximum and minimum margin of a measure, and it means that the real measure will not be greater or less than the values located at the margins.

We know that the surveyed distance is 1200 feet with a margin of error of ±0.1 feet, so, we can calculate the maximum and minimum distances that the reader could assume in the following way:

[tex]MaximumDistance=ActualDistance+0.1feet\\\\MaximumDistance=1200feet+0.1feet=1200.1feet[/tex]

[tex]MinimumDistance=ActualDistance-0.1feet\\\\MaximumDistance=1200feet-0.1feet=1199.9feet[/tex]
