A=x+y+z/3
a-x=y+z/3
a-x-z/3=y
so y=a-x-z/3

Gemiola [76]

It would be 8.5 because all you have to do is add 3 to 2.5 then you’ll get 5.5 then do that one more time.

The volume of a cylindrical container

Ray Of Light [21]

Answer:

A. $\frac{3}{4}\textrm{ gal}$

Step-by-step explanation:

Given:

Volume of the cylindrical container before dilation, $V_{i}=1\textrm{ gal}$

Scale factor of the dilation, $SF=\frac{3}{4}$

Therefore, the volume of the dilated cylinder is given as:

$V_{f}=SF\times V_{i}$

Plug in 1 gal for $V_{i}$ and $\frac{3}{4}$ for SF. Solve for $V_{f}$ . This gives,

$V_{f}=\frac{3}{4}\times 1\\V_{f}=\frac{3}{4}\textrm{ gal}$

Therefore, the volume of the dilated cylinder is $\frac{3}{4}$ gallons.

SHOW that (x + 3) and (x - 2) are factors of f(x) = x4 + 10x3 + 23x2 - 34x - 120.

Anna35 [415]

If f(x) = 0 then it is a root

x + 3 = 0
x=-3
f(-3) = (-3)^4 + 10(-3)^3 + 23(-3)^2 - 34(-3) - 120 = 0

x - 2 = 0
x=2
f(2) = (2)^4 + 10(2)^3 + 23(2)^2 - 34(2) - 120 = 0
