Answer:hope help
Step-by-step explanation:
Find the range by listing all the y values from the ordered pairs. Repeated values within the domain or range don't have to be listed more than once. In order for a relation to be a function, each x must correspond with only one y value.
When you solve proportions, you have to cross multiply.
9 x
--- = --- Multiply each numerator by the opposite denominator.
11 22
(9)(22) = 11x Then, multiply.
198 = 11x Then, divide.
18 = x
Explanation is in the photo
Well we know that the volume of a cylinder equals (area of base) (height)
225pi=a*9
divide both sides by 9
25pi=a
a=pir^2
25pi=pir^2
cancel out pi
25=r^2
5=r so the length of the radius is 5
Answer:
No. The amounts of change are the same, but the original amounts are different.
