If h = 18 units and r = 8 units, then what is the volume of the cone shown above? A. B. C. D.
katen-ka-za [31]

1,205.76 units^3 or 384 π

<u><em>Here is why:</em></u>

The formula for the volume of a cone is:

V=\frac{1}{3}\pi r^2 h

We can plug in.

V=\frac{1}{3}*3.14*8*8*18

= 1,205.76 units^3

~

If you are looking for the exact answer, we will leave π.

V=\frac{1}{3}*\pi*8*8*18

= 384 π

A company is selling books. It has to pay $500 to start printing the books, and once they have done that, the books sell at $14.99 each. How many books must they sell to make a profit?

First we would model an equation. X will be the amount of books sold, and Y will be profits (in dollars obv). They had to pay $500 before they could start selling, so we must account for that too.

This equation would be y=14.99x-500 because for every book sold, X increases by 1, increasing Y by 14.99

The answer would be 34 books sold in order to turn a profit. (500/14.99=

Which values of P and Q result in an equation with no solutions?
Ad libitum [116K]

Try this solution/explanation:

<u>way 1</u>:

rule: for an equation where no roots P+Q=0. It means, Px-Qx=0, ⇔ x(P-Q)=0, ⇔ P=Q.

for answer 'D' P=Q=15.

<u>way 2</u>:

rule: if an equation of the line has a form y=kx+b, then y₁||y₂ if k₁=k₂. It means, for y₁=Px-45 || y₂=Qx+75, then P=Q. P=Q, if 'D' answer.

Answer: D
