An exponential function is expressed in the form y=axb^x. The relation represents a growth when _______ and a decay when ______.

seropon [69]

Answer:

Growth when: b>1.

Decay when: 0<b<1.

Step-by-step explanation:

Any function in the form $f(x)=a{\times}b^x$ , where a > 0, b > 0 and b not equal to $1$ is called an exponential function with base b.

If 0 < b < 1 this is an example of an exponential decay.

The general shape of an exponential with b > 1 is an example of exponential growth.

Hence,

An exponential function is expressed in the form $f(x)=a{\times}b^x$ , The relation represents a growth when b >1 and a decay when 0<b<1.

Find the circumference of a circle with a radius of 35 inches in terms of 7 and to the nearest tenth of an inch.

Lera25 [3.4K]

Answer and Step-by-step explanation:

The circumference formula for a circle is:

C = $2\pi r$

Plug 35 in for r (radius) and solve.

C = $(35) 2\pi\\\\C = 70\pi\\\\C = 219.9$

So, approximately 219.9 $in^2$ is the answer.
