PLZ HELP!! PLZ !!!!!!!!!!!!!
adoni [48]

Answer:The volume of the reservoirs in in^3 is:

V = 30*14*(3/2)*12* (since 1 ft = 12 in)

1 gal = 231 in^3

((7/8)V) : 231 = ((7/8)30*14*(3/2)*12)/231 = 28.64 gal

28.64 gallons of oil are required to fill the reservoir to 7/8 of its depth.

Step-by-step explanation: i hope this help you if not please let me know :)

Whats the domain for this equation?
fgiga [73]

Strictly speaking an equation does not have a domain. A function does. Though it may make sense to speak about a solution set to this equation over a domain.

The following could be helpful towards an answer: The equation has two sides. The left hand side is a non-linear function and the right hand side is a line with slope -1 and y-intercept of 1.

The function\log_5(6-5^x) has a domain over all Reals x for which it holds 6-5^x > 0 \\6 > 5^x\\\log_5 6 > x so the domain of the nonlinear function is -\infty.

The domain of the linear function 1-x is all Reals: -\infty

So, together you could say the equation's solutions are defined over the domain -\infty.

Lmk if you have questions.
