Answer:
$22.70
Step-by-step explanation:
First, find out how much 1 gallon costs. To do this, divide 15.89 by 7.
So, one gallon costs 2.27. Then multiply that by 10 to get 22.7.
Given the function, f(x) = 9 - x :
To evaluate f(4), we must substitute 4 into the given function as an input value for x:
f(4) = 9 - 4
f(4) = 5
Therefore, f(4) = 5.
Answer:
65
Step-by-step explanation:
If the intent of the question is to estimate, I would say do so through rounding. 12.95 is basically 13 and 5.2 is basically 5. So 13 x 5 = 65 would be a good estimate.
Answer: The table that represents a function is table A
Step-by-step explanation: This is because every time the input goes down once with a change of output, where as a nonlinear function doesn't do this
Well, the formula for the volume of a cylinder is V=πr²h so you would have to plug the numbers in next. The radius would be 6, because the diameter is 12. When you plug all of the numbers in, the equation would be V= 3.14×6²×4. Then you solve.
V= 3.14×36×4
V= 113.04×4
V= 452.16
The volume of the cylinder is 452.16 ft³.
