The first thing that comes to mind that an absolute value cannot have a nagative output, in other words, if you have an function that is equal to a negative number, then there is no solution.

blagie [28]

Answer:

37.5 miles

Step-by-step explanation:

We can find the rate of conversion by dividing kilometers by miles. 5÷8=1.6, so 1.6 km = 1 mile. Now we can divide 60 by 1.6 to find miles.

$60/1.6=37.5$

If f x equals x -3 + g x equals 1 - x 2 - 9 find ( f og) (x and give any restrictions on its domain

evablogger [386]

$\begin{gathered} f(x)=x-3 \\ g(x)=\frac{1}{x^2-9} \\ (\text{fog)(x)}=\frac{1}{x^2-9}-3 \end{gathered}$

the denominator cannot be zero, because the division by zero is not defined, therefore:

$\begin{gathered} x^2-9=0 \\ \text{Solving for x:} \\ x^2=9 \\ \sqrt[]{x^2}=\sqrt[]{9} \\ x=\pm3 \end{gathered}$

Therefore the domain of (f o g)(x) is:

$D\colon(-\infty,-3)\cup(-3,3)\cup(3,\infty)$

If a = 2 cm and r = 3.4 cm, find the area of the regular pentagon.

cricket20 [7]

Answer:

$Area = 3.4\ cm^{2}$

Step-by-step explanation:

Assume a pentagon has equal length where a be the side of the pentagon and r be the apothem of the pentagon.

Given:

Sides of pentagon $a=2\ cm$

apothem of pentagon $r=3.4\ cm$

The area of the pentagon formula is given below.

$A = \frac{1}{2}\times bh$

Where b = length of the base or side

And h = height of apothem

Now, we substitute side and apothem length in above formula.

$A = \frac{1}{2}\times 2\times 3.4$

$A = 3.4\ cm^{2}$

Therefore, the area of the pentagon is $3.4\ cm^{2}$
