Answer:
8π in^2 or 25.13 in^2 to the nearest hundredth.
Step-by-step explanation:
The total area = π * 8^2 = 64π in^2
so each slice has an area of 8π in^2.
Answer:
123
Step-by-step explanation:
The given function is :

We need to find the value of f(9). It can be done by putting x = 9 in the above function as follows :

So, the value of f(9) is 123.
No this isn’t a function because it doesn’t pass the vertical line test.
Answer:6 seconds
Step-by-step explanation:
Answer:
-7/13
Step-by-step explanation:
(1 + 7x) - 6 * (-7 - x) = 36 Distribute the 6 into (-7 - x)
1 + 7x + 42 + 6x = 36 Combine like terms (1 + 42) & (7x + 6x)
43 + 13x = 36 Subtract 43 from both sides
13x = -7 Divide by 13
x = -7/13
