Answer:

f(9) = 189

Step-by-step explanation:

Plug 9 into x

f(9) = 2(9)^2 + 3(9)

f(9) = 2(81) + 27

f(9) = 162 + 27

Thus, f(9) = 189

Since the model is 1/13 the size of the tent, you multiply 6” by 13 to get 78”. Since you want feet, you divide 78” by 12” because there are 12 inches in a foot and you want to convert the unit to feet. The answer is 6.5 feet or 6.5’

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
leonid [27]

The Volume of PYRAMID A is 8 times greater than the Volume of PYRAMID B as obtained by taking the ratio of the volume of both pyramids.

Volume of a square based pyramid is given as :

V = a^2h/3

Where; h = height ; a = base edge

Hence, Volume of PYRAMID A :

V = 14^2 * (6/3)\\\\V = 392 in^3

Volume of PYRAMID B = 3,136 in³

Divide Volume of pyramid B by pyramid A :

3136 in^3 / 392 in^3

= 8 times

Expressing as a percentage, multiply by 100% ;

8 * 100% = 800%

Therefore, The volume of PYRAMID B is 800% times GREATER THAN that of PYRAMID A.
