The value of a small airplane depreciates exponentially every year after it is purchased. The value, in thousands of dollars, a(t), of Plane X, t years after purchase can be approximated by this function. a(t) = 131.5(0.8)
What does the number 131.5 in the function above represent in the context of the situation?

assuming you mean addition: addition and subtraction are reverse operations.

step-by-step explanation:

d

step-by-step explanation:

6(h+1)/2=a

a=area

step-by-step explanation:

its the same thing as a square or rectangle but after multiplying two sides you need to divide it by two.

hi there!

step-by-step explanation:

a roof pitch is basically for every inch rise there is 12 inches run.

the height of the roof is also known as the rafter.

formula: rafter^2 = rise^2 + run^2

rafter^2 = 5^2 + 12^2

rafter^2 = 25 + 144

rafter ^2 = 169"^2

the height of the roof from the lowest point to the highest point is 169"^2.

hope this : )
