Answer:

<h2>f(-2) = 12.5</h2>

Step-by-step explanation:

f(t)=2(0.4)^t

f(-2) → put t = -2 to the equation of the function:

f(-2)=2(0.4)^{-2}=2\left(\dfrac{4}{10}\right)^{-2}=2\left(\dfrac{2}{5}\right)^{-2}

Use a^{-n}=\left(\dfrac{1}{a}\right)^n

f(-2)=2\left(\dfrac{5}{2}\right)^2=2\left(\dfrac{25}{4}\right)=\dfrac{25}{2}=12.5

A triangular frame has sides that measure 15'-7",20'-4" and 26'-2". What is the total length of three sides?
meriva

Answer:

The total length of three sides is 62'-1"

Step-by-step explanation:

We know that 1 foot = 12 inches and 1' = 12''

Part 1)

We also know that side 1=15'-7", side 2=20'-4", side 3=26'-2"

To find the total length of three sides sum the three sides

So the total length=side 1+side 2 +side 3

Now we substitute

Total length=15'-7"+20'-4"+26'-2"

Total length=(15'+20'+26')+(7"+4"+2")

Total length=(61')+(13")

Remember that 12"=1'

13"=12"+1"=1'+1"

Substitute again

Total length=(61')+(1'+1")

Total length=(62')+(1")---------> 62'-1"

<u>Therefore the answer is the total length of three sides is 62'-1"</u>
