An open-topped glass aquarium with a square base is designed to hold 444 cubic feet of water. What is the minimum exterior surfa

In-s [12.5K]

Answer:

291.05ft²

Step-by-step explanation:

Volume of the aquarium = L³

L is the length of one side of the aquarium

444 = L³

L = cuberoot[444]

L= 7.63ft

Since the glass aquarium is opened at the top

Total surface Area = 5L²

Total surface Area = 5(7.63)²

Total surface Area = 291.05ft²

Hence the minimum exterior surface area of the aquarium is 291.05ft²

Given the function f(x) = 2|x + 6| -4, for what values of x is f(x) = 6?

photoshop1234 [79]

Answer:

f(x) = 2|x + 6|-4

6=2|x + 6|-4

10= 2|x + 6|

divide by 2

5=|x + 6|

x = 5-6

x = -1

so x should be -1
