31 x 7.875 = 244.125
244.125 inches altogether
He rowed 31.5 miles in half of an hour, to get speed per hour, you multiply by two.
31.5*2=63
Doug's average speed is 63 miles per hour~_~
X=4/log(2) Hope this helps!
The inverse of this function would be f(x) =
.
You can find the value of any inverse function by switching the f(x) and the x value. Then you can solve for the new f(x) value. The end result will be your new inverse function. The step-by-step process is below.
f(x) =
- 1 ----> Switch f(x) and x
x =
- 1 ----> Add 1 to both sides
x + 1 =
-----> Take the logarithm of both sides in order to get the f(x) out of the exponent
Log(x + 1) = f(x)Log3 ----> Now divide both sides by Log3
= f(x) ----> And switch the order for formatting purposes.
f(x) = 
And that would be your new inverse function.
