Answer:

f(-2)=-2

Step-by-step explanation:

we know that

x -----> is the independent variable or input value

f(x) ---> is the dependent variable or output value

f(-2) is the value of the function f(x) when the value of x is equal to -2

For x=-2

Looking at the graph

f(-2)=-2

For an input value of -2 the output value is -2

Bearing in mind that an absolute value expression is in effect a piece-wise function with two cases, thus

$\bf |-n|=
\begin{cases}
+(-n)\\
-(-n)
\end{cases}\implies 
\begin{cases}
-n\\
n
\end{cases}
\\\\\\
n|-n|=2n\implies 
\begin{cases}
n-n=2n\implies 0=2n\implies &0=n\\
n+n=2n\implies 2n=2n\impliedby &inconsistent
\end{cases}$

A Right Triangle (ABC) has sides measuring 3 inches and 4 inches. The hypotenuse is 5 inches. A similar right triangle (A'B'C')

fenix001 [56]

Answer:

The length of hypotenuse is 12.5

Step-by-step explanation:

First 7.5 x 7.5 = 56.25

Then 10 x 10 = 100

Add them together 56.25 + 100 = 156.25

Then square root 156.25 and you get 12.5

Find the perimeter of this figure. Please show work.

Elena-2011 [213]

Answer:

40.56 ft

Step-by-step explanation:

The perimeter is the sum of the lengths of the "sides" of this figure. Starting from the left side and working clockwise, the sum is ...

P = left side (8 ft) + top side (10 ft) + semicircle (1/2×8 ft×π) + bottom side (10 ft)

= 28 ft + 4π ft

= (28 +12.56) ft

P = 40.56 ft
