I don't know, I tried to learn it- even the basics- but I vomited on the kitchen table as soon as I practiced an equation.

I'm allergic to algebra.

If a number is divided by a negative number will the outcome be positive?

Zielflug [23.3K]

That would depend...

-4 / -2 = 2........4 / 2 = 2 <== if the signs are the same
but
4 / -2 = -2.......-4 / 2 = -2 <== if the signs are different

So basically, if the signs are the same, the result is positive and if the signs are different, the result is negative

A toy ball in the shape of a sphere expands and contracts. When it is completely closed, it has a diameter of 12.5 inches.Find

lana [24]

The volume of the sphere is $1022.65 \ in^3$

Explanation:

Given that the diameter of the toy ball is 12.5 inches

We need to determine the volume of the toy ball.

The radius of the toy ball is given by

$r=\frac{d}{2}$

$r=\frac{12.5}{2}$

$r=6.25 \ in$

Thus, the radius of the toy ball is 6.25 in

The volume of the sphere can be determined using the formula,

$V=\frac{4}{3} \pi r^{3}$

Substituting the values, we get,

$V=\frac{4}{3} \pi(6.25)^{3}$

Multiplying, we get,

$V=\frac{976.5625 \pi}{3}$

Substituting $\pi=3.14$ , we have,

$V=\frac{976.5625 (3.14)}{3}$

Simplifying, we get,

$V=1022.65 \ in^3$

Thus, the volume of the sphere is $1022.65 \ in^3$

Simplify the expression. What classification describes the resulting polynomial? (3x^2-11x-4)-(2x^2-x-6)

Gnoma [55]

The expression can be simplified to a polynomial of degree 2.

$x^2 - 10x + 2$

<h3>How to simplify the expression?</h3>

Here we have the expression:

$(3x^2 -11x - 4) - (2x^2 - x - 6)$

We can directly simplify this by taking the variable as common factor:

$(3 - 2)*x^2 + (-11 + 1)*x + (-4 + 6)\\\\x^2 - 10x + 2$

This is a polynomial, as you can see, the maximum exponent is 2, so the degree of the polynomial is 2.

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.
