Answer: -2 and 9

Step-by-step explanation:

Zeros are the numerical values that will make the value of a function 0.

To make g(x) equal 0, 2(x+2)(x-9) must equal 0.

That means that one of the three factors (2, (x+2), or (x-9)) must have a value of 0, because if 0 is multiplied by the rest, the result with always be 0.

2 cannot equal 0.

If (x+2)=0, x=-2

If (x-9)=0, x=9

Wilbur runs 3.2 km every morning how many feet are in 3.2 km given that 1 mile = 1.609 km and 1 mile = 5,280

Nonamiya [84]

1.609/5280 = 3.2/x....1.609 km to 5380 ft = 3.2 km to x ft
cross multiply because this is a proportion
(1.609)(x) = (5280)(3.2)
1.609x = 16896
x = 16896/1.609
x = 10,500 ft <===

The radius AND height of a cone are each doubled. What is the new volume? A) 4 3 πhr2 B) 8 3 πhr2 C) 4πhr2 D) 8πhr2

Jlenok [28]

Volume of cone:
$V = \dfrac{1}{3}\pi r^2h$

Double the radius to 2r, and double the height to 2h.
Volume of new larger cone:
$V = \dfrac{1}{3}\pi(2r)^2 \times 2h$

$V = \dfrac{1}{3}\pi \times 4r^2 \times 2h$

$V = \dfrac{1}{3}\pi \times 8r^2 h$

$V = \dfrac{8}{3}\pi r^2 h$
