If $12001200 is invested at interest rate i, compounded annually, in 55 yr it will grow to an amount A given by Aequals=$1200 (1 plus i )Superscript 51200(1+i)5. a) Find the rate of change, StartFraction dA Over di EndFraction dA di b) Interpret the meaning of StartFraction dA Over di EndFraction dA di.

c. y = 1/4 x + 5

step-by-step explanation:

first, put the equation of the line on the graph into slope-intercept form

(y = mx + b):   y = -4x + 8

second, a perpendicular line has to have "an opposite/reciprocal slope" to the original slope. so, find the "m" value in your original equation (it's -4, right? )

original slope: m = -4   perpendicular slope: change the sign to its opposite and find the reciprocal ("flip" the number)

new slope is now positive (b/c the original slope was negative 4), and it's 1/4 (not the original slope of 4 or 4/1)

answer is because 4×10=40

and 98×4= is 392

40,392
