Answer:

I think it's 96 not sure though

Answer:

64 is a perfect square, because the square root of 64 is 8. If you mean divided by 64, it would be 16 because 16x4=64.

-11x+9 is the answer

Answer:

[tex]x - 1 + ( - 12x) + 10 \\ x - 1 - 12x + 10 \\ x - 12x - 1 + 10 \\ = - 11x + 9[/tex]

Answer:

y – 1= Three-halves(x + 3)

Step-by-step explanation:

line goes through  (-2, -4) and (2, 2)

goes through (-3, 1)

slope =  (-4 - 2) / (-2 -2)  = -6/-4 = 3/2

1 =  (3/2)*-3 + b

1 = -9/2 + b

b = 1 + 9/2 = 11/2 = 5.5

y = (3/2)*x + 11/2

(y - 1) = (3/2)(x + 3)

The line goes through  (-2, -4) and (2, 2)

goes through (-3, 1)

If slope = (-4 - 2) / (-2 -2)  = -6/-4 = 3/

1 =  (3/2)*-3 + b

1 = -9/2 + b

b = 1 + 9/2 = 11/2 = 5.5

y = (3/2)*x + 11/2

(y - 1) = (3/2)(x + 3)

So the correct answer is option d. y – 1= Three-halves(x + 3).

A coordinate plane is a graphing and description system for points and lines. A vertical (y) axis and a horizontal (x) axis make up the coordinate plane. There are four quadrants in the coordinate plane. The point where these lines connect is called the origin (0, 0).

Answer:

cytokineses

Step-by-step explanation:

The phase of the cell cycle where the cytoplasm splits apart and the cell separates into two identical daughter cells is referred to as cytokinesis.

The phase of the cell cycle in which the cytoplasm splits apart and the cell separates into two identical daughter cells is called cytokinesis.

Cytokinesis usually follows the other stages of the cell cycle. To put these stages in context: anaphase is the phase in which the chromosomes separate, followed by telophase, in which the separated chromosomes reach opposite ends of the cell. Cytokinesis then occurs, physically splitting the cell in two and thereby creating two identical daughter cells.

Answer:

its 6

Step-by-step explanation:

A soccer ball is in the form of a Sphere.

Volume of a Sphere: V = (4/3)πr3

In this case, V = 288π cm3. So:

1) Substitute the known value into the equation: 288π = (4/3)πr3

2) Notice the π value is on either side of the equation. It cancels: 288 = (4/3)r3

3) Simplifying: r3 = 216

4) Solving for r yeilds : r = 6 cm

The radius (r) of a soccer ball with a volume of 288 cm3 is 6 cm

Answer:

y = 30.85

10.85

Step-by-step explanation:

One complete cycle is between:

x = 4 and x = 44

Period: 44-4 = 40 cm

Range: 41.7 - 20 = 21.7

Amplitude: 21.7/2 = 10.85

Mean line:

y = 20 + 10.85

y = 30.85

The period of the cosine function is 20, its midline equation is y = 32, and its amplitude is [tex]$\boxed{12}$[/tex].

To analyze the given data, we can notice the sinusoidal nature of the relationship between the number of seconds an object has been moving (x) and its velocity (v(x)$. This indicates that a cosine function can model the data.

Now, let's find the period, midline, and amplitude of the cosine function that models this data.

The period of a cosine function is the distance it takes for the function to complete one full cycle. Looking at the data, we can see that the interval between consecutive peaks or troughs (e.g., between 4 and 24, or 24 and 44) is 20 seconds.

Hence, the period of the cosine function is 20.

The midline of a cosine function is the horizontal line that divides the maximum and minimum values of the function. In this case, since the data oscillates around a central value, it suggests that the midline is not at y = 0.

Instead, it's the average of the maximum and minimum values of the data. The maximum value is 44 and the minimum value is 20, so the midline would be the average of these, which is (44 + 20)/2 = 32.

The amplitude of a cosine function is half the difference between the maximum and minimum values.

In this case, the maximum value is 44 and the minimum value is 20, so the amplitude is (44 - 20)/2 = 12.

So, completing the statements:

- The period of the cosine function is 20.

- The equation of the midline of the cosine function is y = 32.

- The amplitude of the cosine function is [tex]$\boxed{12}$[/tex].

Answer: [tex]x^{2} +4x - 12 = 0[/tex]

Step-by-step explanation:

To find the quadratic equation when the roots are given , we will use the formula:

[tex]x^{2} -[/tex] sum of roots[tex](x)[/tex] + product of roots = 0

sum of roots = -6 + 2 = -4

product of roots = -6(2) = -12

substituting into the formula, we have

[tex]x^{2} - (-4) +(-12) = 0[/tex]

[tex]x^{2} +4x - 12 = 0[/tex]

Step-by-step explanation:

Answer:

7 book cases

Step-by-step explanation:

Add 115 to itself until you reach past 360 (there is a remainder). 115 added 3 times is 345. 115 books=2 bookcases. So you multiply: 2×3=6. Since there is not enough room for all 360 books in 6 bookcases, you need 1 more, which makes it 7 bookcases.

This is a vertical parabola open upward

The vertex represent a minimum

The vertex is the point (-5,-6.5)

The domain is all real numbers

The range is the interval [-6.5,∞)

so

At the left of the x-coordinate of the vertex the function is decreasing and at the right of the x-coordinate of the vertex the function is increasing

therefore

The function is increasing in the interval (-5,∞) and the function is decreasing in the interval (-∞,-5)
