Assume that in October of a particular year about 215 billion text messages were sent or received in the US, and the prediction

Julli [10]

Answer:

There will be $243$ billion messages sent or received in November.

Step-by-step explanation:

Given.

Number of text messages sent or received $=215$ billion.

Increment on the very next month $=13\%=\frac{13}{100}=0.13$

Lets find what is $13\%\ of\ 215$

⇒ $13\%\ of\ 215$

⇒ $0.13\times 215=27.95$

So we will add this value to our previous months data.

Now

Number of text messages sent in the month of November $=(27.5+215)=242.95$ billion.

Rounding to the nearest tenth the answer will be $243$ billion.

So $243$ billion text messages were sent or received in November.

Find the average rate of change for the given function over the indicated values of x. If necessary, round your final answer to

Pavlova-9 [17]

Answer:

The average rate of change of the function in this interval is of 18.

Step-by-step explanation:

The average rate of change of a function $f(x)$ in an interval from a to b is given by:

$A = \frac{f(b) - f(a)}{b - a}$

In this question:

$f(x) = x^2 + 6x$

Where x goes from 5 to 7.

This means that $b = 7, a = 5$ . So

$f(7) = 7^2 + 6(7) = 49 + 42 = 91$

$f(5) = 5^2 + 6(5) = 25 + 30 = 55$

The rate of change is:

$A = \frac{f(7) - f(5)}{7 - 5} = \frac{91 - 55}{2} = 18$

The average rate of change of the function in this interval is of 18.
