Roger invested a certain amount into an account with an interest rate of 10 percent compounded annually. It will take approximately A. 10.4 B. 11.5 C. 15.2 years before Roger’s investment is triple the original amount invested. If his friend invested twice as much as Roger in the same bank, it takes A. less B. more C. time for his investment to triple the original amount invested.

the answer is here: : )

:

e) none of the above because the measure of angle cba is 101°

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)
