Help help help if u can answer this I’ll mark u brainliest (6) (the one in the middle)
Hoochie [10]

You just have to plug in each thing:

So f(0):

3(0)^2 - 4 = -4

so its not A

f(-2) and f(2):

3(-2)^2 - 4

3(2)^2 -4

now we don't even have to calculate these, anything to the power of an even number is a positive number so -2^2 and 2^2 both equal 4

B is correct, so you can do the others if you want to check, but if B is true the others shouldn't be true.

Pyramid A is a square pyramid with a base side length of 14 inches and a height of 6 inches. Pyramid B has a volume of 3,136 cub
mash [69]

Answer:

12.5%    Step 1  to find volume of Pyramid A  Step 2 is find percentage through division then multiplication of 100  

Step-by-step explanation:   Length of one side of the base (a) = 14 in

Height of square pyramid (h) = 6 in

Using the square pyramid volume formula,

Volume = 1/3 x a^2 x h

Volume = 1/3 x 14^2 x 6

Volume = 392 in3

The volume Pyramid A is 392 cubic inches.

Pyramid A has a volume = 392 cubic units     Pyramid B has a volume of 3,136 cubic inches.    to find percentage 392 of 3136 we divide then * 100   To find percentage, we need to find an equivalent fraction with denominator 100. Multiply both numerator & denominator...  = (392/3136 ) x 100% = 12.5%   Proof is  (12.5 * 3136 ) / 100 = 392
