Answer:
5ft
Step-by-step explanation:
According to the scenario, computation of the given data are as follows,
Volume = 25π ft cubed
Depth = 3 ft
So, we can calculate the radius by using following formula,
V = 1/3 ×π ×radius squared×depth
25π = 1/3×π×radius squared ×3
Radius squared = 25
Radius = √25
Radius = 5 ft
Hence the radius of the hole is 5 ft.
Answer:B
Step-by-step explanation:
Answer:
a) The domain of f(x) is .
b)
The inverse function is:
So we need
Applying ln to both sides
So the domain of f(x) is .
(b) Find F −1 and its domain.
is the inverse function of f.
How do we find the inverse function?
To find the inverse equation, we change y with x to form the new equation, and then we isolate y in the new equation. So:
Original equation:
f(x) = y = \ln{e^{x} - 3}
New equation
Here, we apply the exponential to both sides:
Applying ln to both sides
The inverse function is:
The domain is
is always a positive number, so it is always going to be larger than -3 no matter the value of x. So the domain are all the real values.
Circumference of the circle = pi * diameter = 3.14 * 13 = 40.82
Length of EG = 40.82 * 280 / 360 = 31.7 cm.
