The side length, s, of a cube is x – 2y. If V = s3, what is the volume of the cube?

hope this helps :)

Step-by-step explanation:

dh/dt=-32t+32

When velocity, dh/dt, is equal to zero, the object is at its maximum height.

dh/dt=0 only when 32t=32, t=1 second, so the maximum height is h(1)

h(1)=-16+32=16ft

Using algebra

The maximum height will occur at the midpoint between the two zeros of the height function because of a quadratics symmetry...

h(t)=0 when

-16t^2+32t=0

-16t(t-2)=0

so t=0 and 2

The midpoint is t=1

And of course this will give you the same as we found earlier.  The maximum height is h(1) ft

Step-by-step explanation:

Answer:

This is because this equation equals 0 when x = -5

Step-by-step explanation:

To find this, plug the value in for x.

-1.3x - 6.5

-1.3(-5) - 6.5

6.5 - 6.5

0

The expression -1.3x - 6.5 evaluated at x=-5 equals zero, which is why it is neither positive nor negative.

To verify this let's evaluate it step by step.

Substitute x = -5 into the expression:

-1.3(-5) - 6.5

Then, multiply -1.3 by -5:

-1.3 * (-5) = 6.5

Then, subtract 6.5:

6.5 - 6.5 = 0

The expression -1.3x - 6.5 evaluated at x=-5 equals zero, which is why it is neither positive nor negative.

Circumference is found by multiplying the diameter by PI,

so a circumference of 6PI means the diameter is 6 inches.

Area is found using the formula PI x r^2

r = 1/2 the diameter

r = 6/2 = 3

The area becomes 3^2 x PI = 9PI inches.

The answer is C.

The "-4" tacked onto the 2x^2 term will move the entire parabola down 4 units. This is because y = 2x^2 becomes y-4 = 2x^2-4

The y-4 means we move every y coordinate down 4 spots. The x coordinate stays the same.

Step-by-step explanation:

Answer: The figure has 1 line of symmetry.

Step-by-step explanation:

A figure is said to has a line of symmetry if we can draw a line that divides the entire figure into two equal halves, so that each half appears as a reflection image or the mirror of the other.

In the given picture , if given a figure of alphabet W.

It has only a vertical symmetry ( see below the line of symmetry divides W into two Vs) but no horizontal symmetry and any other symmetry.

Therefore , it has only one line of symmetry.

Hence, the figure has 1 line of symmetry.

Answer:

D.) 2.5 miles

Step-by-step explanation:

The first step required for solving this problem is to calculate the midpoint between the theater and the mall (2, 1.5). Then use the distance formula to calculate the distance from the bowling alley to the mall.

The distance from the bowling alley to the mall is 2.5 miles. The coordinates of the midpoint, which is the location of the bowling alley, are calculated first. Then, using the Pythagorean theorem, the distance to the mall is found by calculating the square root of the sum of the squares of the horizontal and vertical distances.

The task is to calculate the distance from the bowling alley to the mall if the bowling alley is at the midpoint between the movie theater at (0,0) and the mall at (4,3). First, we find the coordinates of the midpoint, which is the average of the x-coordinates and the y-coordinates of the two points respectively. Thus, the midpoint is located at:

So, the bowling alley is at point (2, 1.5). Secondly, we use the Pythagorean theorem to find the distance from the bowling alley to the mall:

Applying the distance formula (or Pythagorean theorem):

Distance = √( Δx² + Δy² ) = √( 2² + 1.5² ) = √( 4 + 2.25 ) = √6.25 = 2.5 miles

Therefore, the approximate distance from the bowling alley to the mall is 2.5 miles, which corresponds to answer (D).

The total surface area of a square pyramid with a side length of 4 feet and a height of 6 feet is 64 square feet.

To find the total surface area of a square pyramid, we need to calculate the area of the base and the area of all four triangular faces. The area of the base (a square) can be found using the formula side². In this case, that's 4² which equals 16 square feet. To find the area of a triangular face, we use the formula 0.5 * base * height. Since we have 4 identical triangular faces, we calculate this once and then multiply by 4. The base of each triangle is the side of the square, which is 4 feet, and the height is given as 6 feet. Plugging these values into the formula we get 0.5 * 4 * 6 = 12 square feet for one triangular face. Since there are 4 of these faces, the total surface area of the faces is 4 * 12 = 48 square feet. Adding this to the area of the base, we find the total surface area of the pyramid is 16 + 48 = 64 square feet.

To find the total area of a square pyramid, calculate the area of the base and the area of the four triangular faces. The total area is 64 square feet.

To find the total area of a square pyramid, you need to calculate the area of the base and the area of the four triangular faces. Since the base is a square with sides measuring 4 feet, its area is 4 x 4 = 16 square feet.

To find the area of each triangular face, you can use the formula for the area of a triangle: (base x height) / 2.

In this case, the base of each triangular face is 4 feet and the height is 6 feet, so the area of each face is (4 x 6) / 2 = 12 square feet. Since there are 4 triangular faces, the total area of these faces is 4 x 12 = 48 square feet.

Finally, you can find the total area of the pyramid by adding the area of the base and the area of the faces: 16 + 48 = 64 square feet.

Therefore, the total area of the square pyramid is 64 square feet.

Original measurements:

L = 4; W = 6; H = 7

surface area = 2(LW + LH + HW)

surface area = 2(4 * 6 + 4 * 7 + 6 * 7)

surface area = 2(24 + 28 + 42)

surface area = 2(94)

surface area = 188

Doubled measurements:

L = 8; W = 12; H = 14

surface area = 2(LW + LH + HW)

surface area = 2(8 * 12 + 8 * 14 + 12 * 14)

surface area = 2(96 + 112 + 168)

surface area = 2(376)

surface area = 752

The surface area was 188 square inches and it became 752 square inches.

752/188 = 4

As the side lengths increased by a factor of 2, the surface area increased by a factor of 4.

Answer:

x=2 ; x=-4 or x=-3/2

Step-by-step explanation:

We are given a cubic polynomial

[tex]2x^3+7x^2-10x-24=0[/tex]  

Here as we are having a cubic equation to factorize, we have to find some value of x such that when we put that value in place of x , it gives us a 0. We have to try it randomly like first we try it for x=1 then x=2 and so on.

On trying for x=2 , we see that the equation becomes 0=0 and hence x=2 is one of the solution. And also as x=2 is one of the solution, (x-2) must be one of the factor. Now we use this property to determine the other factor like this.

[tex]2x^3+7x^2-10x-24=0[/tex]

Adding and subtracing [tex]4x^2[/tex] to [tex]2x^3[/tex] we get

[tex]2x^3-4x^2+4x^2+7x^2-10x-24=0[/tex]

Now we take out [tex]2x^2[/tex] as GCF

[tex]2x^2(x-2)+11x^2-10x-24=0[/tex]

Now subtracting and adding [tex]22x[/tex] to [tex]11x^2[/tex]

[tex]2x^2(x-2)+11x^2-22x+22x-10x-24=0[/tex]

taking [tex]11x^2[/tex] as GCF out  

[tex]2x^2(x-2)+11x(x-2)+22x-10x-24=0[/tex]

[tex]2x^2(x-2)+11x(x-2)+12x-24=0[/tex]

[tex]2x^2(x-2)+11x(x-2)+12(x-2)=0[/tex]

Now taking [tex](x-2)[/tex] out as GCF

[tex](x-2)(2x^2+11x+12)[/tex]

Now we need to split the middle term of [tex](2x^2+11x+12)[/tex] to factorize it in such a way that their product is 2*12 and sum is 11. We have 8 and 3 as these factors.

Hence it can be factored like this

[tex](2x^2+11x+12)\\2x^2+8x+3x+12\\2x(x+4)+3(x+4)\\(2x+3)(x+4)[/tex]

Hence our answer will be

[tex](x-2)(2x+3)(x+4)=0[/tex]

And thus the solutions will be

x-2=0 : x=2

x+4=0 ; x=-4

2x+3=0 ; x=-[tex]\frac{3}{2}[/tex]

To find intervals of increase or decrease, analyze the function's derivative or slope. Linear regression uses a straight line equation to estimate these trends graphically. Graphs are helpful for visually representing increase or decrease rates and other numerical relationships.

To find intervals of increase or decrease in a function, you need to analyze the function's derivative. If the derivative is positive over an interval, the function is increasing; if the derivative is negative, the function is decreasing. An example of observing such behavior is through graphical analysis, where you look for portions of the graph that have an upward or downward slope, respectively.

Linear regression is a tool used to determine the rate of increase or decrease over a set of data points. By fitting a line X = S\u00d7t + I, where S is the slope and I the intercept with the vertical axis, one can estimate the trend or rate of change, assuming a linear relationship.

To describe the rate of growth in various contexts, such as population growth or economic data, graphs can display these trends visually. For different applications, such as contour mapping in geography, the interval of change might be adjusted to represent details accurately. A constant rate of growth assumption, however, isn't always correct and must be adjusted depending on the circumstances.

Answer:

3/8 or 37.5%

Step-by-step explanation:

There are a total of 8 possible outcomes. B appears only 3 times in those 8 outcomes. Therefore, the chances of landing on B is 3 out of 8 or 3/8.

The probability of B in percent is 37.5 %.

Probability can be defined as the ratio of the number of favorable outcomes to the total number of outcomes of an event.

Here, Total outcomes = {A, A, B, B, B, C, C, C}

                 n(S) = 8

Now, possibility of B = {B, B, B}

                n(B) = 3

Probability of B = Favorable outcomes/ total outcomes

                           = n(B)  / n(S)

                           = 3/8

                           = 0.375

                           = 37.5 %

Thus, the probability of B in percent is 37.5 %.
