Answer:
f^-1 = 4(x-3)
Step-by-step explanation:
If f(x) = 1/4(x) + 3 we ned to find f^-1.
To find the inverse function, we need to solve the equation for "x", as follows:
f(x) = 1/4(x) + 3
y = 1/4(x) + 3
y-3 = 1/4(x)
4(y-3) = x
Now, change the "x" for an "y". And change the "y" for an "x":
4(x-3) = y
The solution is the last one.
Answer:
2
Step-by-step explanation:
We take the equation
and substitute the values for each individual variable in the problem. It looks like this:
Now we can solve the equation.
When solved, it equals 2.
Answer:
AC = 52.8
Step-by-step explanation:
33/20 = 1.65
12*1.65 = 19.8
BA = 19.8
CB + BA = AC
33 + 19.8 = 52.8
The answer would be 14 cm.
The formula to find diameter is d=2r
D= diameter
R= radius
The 2 is there because you have half of the diameter so just times by 2 to get the diameter.
