What function is the inverse of the exponential function y = (1.5)x?

vagabundo [1.1K]

Correct question is;

What function is the inverse of the exponential function y = 1.5^(x)?

Answer:

y = log_1.5_x

Step-by-step explanation:

The inverse of exponential functions is usually written in form of logarithm.

For example inverse of y = p^(x) will be written as; y = log_p_(x)

Similarly applying this same pattern to our exponential function y = 1.5^(x), we have the inverse as;

y = log_1.5_x

The cylinder is 10 meters wide and the volume is 300 cubic meters what's the height of the cylinder?

daser333 [38]

Cylinder is 10 meters wide, so its diameter is 10 meters. You get radius of it by dividing 10 by 2, which equals 5.
As you count volume of cylinder from that equation
$V=A*h= \pi r^{2}*h$
You get an equation to count height:
$h= \frac{V}{ \pi r^{2} }$
h≈3.82 meters
