Write an equation for computing a tip in a restaurant. does your equation represent a function? if so, what are your choices for the independent and dependent variables? if not, select none in the appropriate blanks.

Say the tip is 11% of the bill. That's 0.11 times the amount of the bill.

Let b = amount of the total bill

Let T = amount of the tip

An equation that describes the situation is

T(b) = 0.11b,

where T is the amount of the tip and b is the amount of the bill.

This equation represents a function. It determines T as a function of b (because the equation is solved for T, and only b appears on the right side).

none of the option is correct.

step-by-step explanation:

it says to find which expression equals 9^3 sqrt 10 = ?

9^3 sqrt 10 = 729 sqrt 10.

checking option a. 5 sqrt 10 + 4 sqrt 10

5 sqrt 10 + 4 sqrt 10

= 9 sqrt 10.

checking option b. 5^3 sqrt 10 + 4^3 sqrt 10

5^3 sqrt 10 + 4^3 sqrt 10

= 125 sqrt 10 + 64 sqrt 10

= 189 sqrt 10.

checking option c. 5 sqrt 10 + 4^3 sqrt 10

5 sqrt 10 + 4^3 sqrt 10

= 5 sqrt 10 + 64 sqrt 10

= 69 sqrt 10.

checking option d. 5^3 sqrt 10 + 4 sqrt 10

5^3 sqrt 10 + 4 sqrt 10

= 125 sqrt 10 + 4 sqrt 10

= 129 sqrt 10.

hence, none of the option is correct.
