Hello there!

So, as we see here, we can see that they start out with 20,000 members. 25% of 20,000 would be 5,000 members.

So, every year, they lose 25% which is 5,000 members of they team. But then they gain 10,000 more.

So, practically, they get 5,000 every year even though they get 25% off.

5,000 would be the answer.

Question 1
sergey [27]
For a rectangular prism, the volume is,
the area of one of the faces * the length of the other unit
so say the base is 9 * 9, then, that base times the height of 16

now, for the triangular prism, the volume is,
the area of one of the triangular faces * the length of the other unit,
so... say, find the area of one of the triangular faces
recall 1/2 b*h

and then multiply that times the other length of 20

Write a quadratic equation with the given roots. Write the equation in the form ax2 + bx + c = 0 where a, b, and c are integers.
Vikki [24]

A quadratic with roots at 8 and 5 is f(x) = x^2 +12x + 20

In order to find an equation given roots you can create statements that equal 0 in order to create parenthesis. For instance we know x = 8 at one point. So, we can solve that to equal 0.

x = -2 ----> add 2 to both sides

x + 2 = 0

We can do the same for the other zero.

x = -10 ----> add 10 to both sides

x + 10 = 0

Now that we have both of these, we can multiply these two things together. This will give us the function we need.

f(x) = (x + 2)(x + 10)

f(x) = x^2 + 10x + 2x + 20

f(x) = x^2 + 12x + 20
