How do I calculate volume

9966 [12]

Answer:

Volume = length x width x height.

You only need to know one side to figure out the volume of a cube.

The units of measure for volume are cubic units.

Volume is in three-dimensions.

You can multiply the sides in any order.

Which side you call length, width, or height doesn't matter.

Coach kunal stacks all of the tennis balls in a square pyramid. The number of tennis balls, P(n), in n layers of the square pyra

Zolol [24]

Answer:

D. 9

Step-by-step explanation:

We are told in the question that: The number of tennis balls represented by P(n), in n layers of the square pyramid is given as

P(n) = P(n - 1) + n²

Let's take the first layer

n = 1

P(1) = P(1 - 1) + 1²

P(1) = 1 tennis ball.

It is important to note that the first layers we have one tennis ball.

Let's take the second layer

n = 2

P(2) = P(2 - 1) + 2²

P(2) = P(1) + 2²

Note that: P(1) above = 1

P(2) = 1 + 2²

P(2) = 5 tennis balls

It is important to note that the second layer we have five tennis balls

Let's take the third layer

n = 3

P(3) = P(3 - 1) + 3²

P(3) = P(2) + 3²

Note that: P(2) above = 5

P(3) = 5 + 3²

P(3) = 14 tennis balls

It is important to note that the second layer we have fourteen tennis balls

Let's take the fourth layer

n = 4

P(4) = P(4 - 1) + 4²

P(3) = P(4 - 1) + 4²

P(3) = P(3) + 4²

Note that: P(3) above = 14

P(3) = 14 + 4²

P(3) = 30 tennis balls

It is important to note that the fourth layer we have thirty tennis balls

Hence, the number of tennis balls from the first four layers will be: 1, 5, 14, 30,

So, the number of tennis balls that Coach Kunal could not have is 9.

I need help with this

lana66690 [7]

16: 10(-9) +4 = -90 +4 = -86

17. 7^2 - 7 = 49-7 = 42

18. -9^2 - -9 = 81+9 = 90

19. 10(5) +4 = 54, 3*54 = 162

20. 3*5 = 15, 10(15) +4 = 154

Find the zeros of the polynomial function: <br> f(x) = 9x^3 - 27x^2 - 4x + 12.

hichkok12 [17]

Answer:

{-2/3, 2/3, 3}

Step-by-step explanation:

The equation can be factored by grouping.

f(x) = (9x^3 -27x^2) +(-4x +12)

f(x) = 9x^2(x -3) -4(x -3)

f(x) = (9x^2 -4)(x -3)

We recognize the first factor as the difference of squares, so know it can be further factored to give ...

f(x) = (3x -2)(3x +2)(x -3)

The zeros are the values of x that make these factors be zero:

3x -2 = 0 ⇒ x = 2/3

3x +2 = 0 ⇒ x = -2/3

x -3 = 0 ⇒ x = 3

The zeros of the polynomial are x = -2/3, 2/3, 3.
