Answer: D) 5832

Step-by-step explanation:

The y values are the x values cubed. Since the x values are increasing by 3, the last x would be 18. 18 cubed is 5832.

Answer:

Step-by-step explanation:

Any side to side movement of a function will be reflected inside a set of parenthesis with the x.  For example, if the function was a parabola, the parent graph could be, very simply,

[tex]y=x^2[/tex]

Side to side movement would make the equation look like this:

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

where h is the x coordinate of the vertex.

Up or down movment would make the equation look like this:

[tex]y=x^2+k[/tex] for movement upwards, or

[tex]y=x^2-k[/tex] for movement downwards.  The k represents the y coordiante of the vertex in this parabola.

Because our function has NO numbers inside the parenthesis with the f(x), but it has a -1 after, we are moving the parent graph of this function, whatever it is, down one from its starting position.

The transformation from the graph of a function f(x) describes the graph of f(x) - 1 is a vertical shift down by 1 unit

From the question, we have the following parameters that can be used in our computation:

The function f(x)

Also, we have

The function f(x) - 1

Subtracting a value from a function means that the function is shifted down

In this case, the subtracted value is 1

This means that f(x) - 1 is a vertical shift down by 1 unit from f(x)

The special at Big Bob's Pizza which will give you more pizza for your money is Choice #1. Per square inch, Choice #1 will cost less and give more overall pizza at $0.10 a square inch then Choice #2 at $0.13 per square inch. You can find more pizza for your money, by using the area formula for a circle for each pizza and finding the price per square inch of each serving. This is called a unit rate and is the cost per unit.

a. Find the radius of each pizza.

Since a pizza is a circle shape, it has a diameter and radius. The diameter is the distance across the pizza and the radius is half the diameter. We use the radius to find the area.

b. Find the area of each pizza using [tex]A = \pi r^{2}[/tex].

       [tex]A = \pi r^{2} \\A = \pi (11)^{2} \\A = 121\pi \\A= 379.94[/tex]

       The area of one slice is [tex]\frac{379.94}{8} = 47.49.[/tex]

       [tex]A = \pi r^{2} \\A = \pi (3)^{2} \\A = 9\pi \\A= 28.26[/tex]

c. Divide each area by the price.

        [tex]\frac{4.95}{47.49} = 0.10[/tex]

       [tex]\frac{3.75}{28.26} = 0.13[/tex]

The slope of the line of best fit is 1.5.

Answer:

The slope of the line of best fit is 1.5 degrees Fahrenheit per gallon.

Step-by-step explanation:

If a line passes through two points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex], then the slope of the line is

The answer is:

The length of the longer side of the rectangle is equal to 45 units.

To solve the problem, we need to use the formula to calculate the perimeter of a rectangle, then, isolate the variable and finally, calculate the length of the longer side.

We can calculate the perimeter of a rectangle using the following equation:

[tex]Perimeter=2Length+2Width\\[/tex]

Let be the length the longer side and the width the short side of the rectangle.

Then, substituting the given information and calculating we have:

Answer:

  No

Step-by-step explanation:

Not all relations have either an infinite domain or an infinite range. Some have no "end behavior". A sine function, for example, continues to oscillate between -1 and +1 forever.

The graphs of some relations are simply a collection of points, so the "end behavior" would be the points at either extreme of the domain.

Answer:

The sixth term is -243/2048 ⇒ answer B

Step-by-step explanation:

* Lets explain the geometric sequence

- There is a constant ratio between each two consecutive numbers

- Ex:

# 5  ,  10  ,  20  ,  40  ,  80  ,  ………………………. (×2)

# 5000  ,  1000  ,  200  ,  40  ,  …………………………(÷5)  

* General term (nth term) of a Geometric sequence:

# U1 = a  ,  U2  = ar  ,  U3  = ar²  ,  U4 = ar³  ,  U5 = ar^4

# Un = ar^(n-1), where a is the first term , r is the constant ratio

  between each two consecutive terms  and n is the position of the

  number in the sequence

- Ex: U5 = ar^4  ,  U7 = ar^6  ,  U10 = ar^9  ,  U12 = ar^11

- Lets solve the problem

∵ The sequence is 1/2 , -3/8 , 9/32

- Lets find the constant ratio r

∵ The first term is a = 1/2

∵ The second term is U2 = ar

∵ The second term  U2 = -3/8

∴ ar = -3/8

∴ 1/2 r = -3/8 ⇒ multiply both sides by 2

∴ r = -3/4

- Lets find the sixth term

∵ a = 1/2 and r = -3/4

∵ n = 6

∴ U6 = ar^5

∴ U6 = 1/2 (-3/4)^5 = 1/2 × -243/1024 = -243/2048

* The sixth term is -243/2048

Step-by-step explanation:

The value of the 8, in 2781, is 10 times the value of the 8, in 948.

Answer:

I believe you mean what square number that is less than 100 has the most factors.  

The square numbers under 100 are 1, 4, 9, 16, 25, 36, 49, 64, and 81.  

1 obviously only factors to 1*1.

4, 9, 25, and 49 are square of prime numbers. If we call the original number n and the root p (for prime) each of them can only be factored as 1*n or p*p. example: 1*4, 2*2 .We can eliminate those.  

16 and 81 are not only squares, but the fourth power of a prime (2 and 3) respectively. They can be factored as 1*n, (p^3)*p, or (p^2*p^2). Example: 1*16, 8*2, or 4*4.

But 36 is 2*2*3*3 as it’s prime factoring. This allows us to find more combinations of factors: 1*36, 2*18, 4*9, 12*3, or 6*6.

Final answer:

The largest even square number smaller than 100 is 64, which is the square of 8.

Explanation:

To find an even square number smaller than 100, we can look at the squares of the even numbers less than 10, since 10² (which is 10 times 10) equals 100. Squaring each even number from 2 to 8, we get the following even square numbers: 2²=4, 4²=16, 6²=36, and 8²=64. Among these, 64 is the largest even square number that is less than 100.

Answer:

  20

Step-by-step explanation:

The ratio of rise to run is 5:2, so if the run is 8, the rise is correspondingly 4 times as much:

  rise : run = 5 : 2 = 20 : 8

A similar right triangle would be created by a run of 8 and a rise of 20.

Answer:

20

Step-by-step explanation:

Step-by-step answer:

Between similar figures, if the ratio between the sides is k, then

- ratio between linear measurements, such as diagonals, perimeter, width, heights, etc, are also linear.

Therefore, if the ratio of the corresponding sides is 1:4, the ratio of their perimeters is also 1:4.

Note:

the ratio of area measurements,  or surface areas of similar solids, are proportional to k^2.

Similarly, the ratio of volumes of similar solids are proportional to k^3.

Answer:

The equation is: y = 5x - 268

Explanation:

We are given that:

At 73°F, the chirp is 97 times per minute .........> first point is (73, 97)

At 80°F, the chirp is 132 times per minute .......> second point is (80, 132)

The general equation of the linear line is:

y = mx + c

where m is the slope and c is the y-intercept

1- getting the slope:

The slope can be calculated using the following rule:

[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

Substitute with the given points to get the slope as follows:

[tex]m = \frac{132 - 97}{80 - 73} = 5[/tex]

The equation, now, became:

y = 5x + c

2- getting the y-intercept:

To get the y-intercept, use any of the given points and substitute in the rule we got in part 1. I will use the point (80, 132)

Therefore:

y = 5x + c

132 = 5(80) + c

c = 132 - 5(80) = -268

The equation, therefore, is:

y = 5x - 268

Answer:

Los Angeles

Step-by-step explanation:

Los Angeles has the least variability in temperatures.

To determine which location has the least variability in temperatures, we need to calculate the range or variance of the temperatures for both Miami and Los Angeles.

For Miami:

Temperatures: 76 75 83 73606676 81 83 85 83 87 8080 74

To calculate the range, we subtract the minimum temperature from the maximum temperature:

Range = Maximum temperature - Minimum temperature

Range = 87 - 73

Range = 14

For Los Angeles:

Temperatures: 63 62 65 72 67 | 65 | 6565 69 64 64 61 3639 62

Again, to calculate the range, we subtract the minimum temperature from the maximum temperature:

Range = Maximum temperature - Minimum temperature

Range = 72 - 61

Range = 11

Comparing the ranges, we see that Miami has a range of 14, while Los Angeles has a range of 11. Therefore, Los Angeles has the least variability in temperatures.

[tex]h(x) = -0.01 (x-150) (x + 4)[/tex]

Step-by-step explanation:

The javelin will have reached its maximum horizontal distance when it touches the ground.

Then the maximum horizontal distance occurs when the height h (x) is equal to zero.

So we must equal h(x) to zero and solve the equation for x.

Therefore the form that is most useful to determine the horizontal distance that the javelin covers is the one that is factored. Because it allows us to find the zeros of the quadratic function more easily

[tex]h(x) = -0.01 (x-150) (x + 4) = 0[/tex]

[tex]-0.01 (x-150) (x + 4) = 0[/tex]

The equation is equal to zero when [tex]x = 150[/tex] or when [tex]x = -4[/tex]
