Mathematics
1 answer:
Soloha48 [4]2 years ago

Answer:

Account A: Decreasing at 8 % per year

Account B: Decreasing at 10.00 % per year

Account B shows the greater percentage change

Step-by-step explanation:

Part A: Percent change from exponential formula

f(x) = 9628(0.92)ˣ

The general formula for an exponential function is

y = ab^x, where

b = the base of the exponential function.

if b < 1, we have an exponential decay function.

ƒ(x) decreases as x increases.

Account A is decreasing each year.

We can rewrite the formula for an exponential decay function as:

y = a(1 – b)ˣ, where

1 – b = the decay factor

b = the percent change in decimal form

If we compare the two formulas, we find

0.92 = 1 - b

b = 1 - 0.92 = 0.08 = 8 %

The account is decreasing at an annual rate of 8 %.The account is decreasing at an annual rate of 10.00 %.

Account B recorded a greater percentage change in the amount of money over the previous year.

HELP!!!!!!!!!!!!!!!!!!!!! !PLEASE SOLVE!<br> y-63=1/2(x-64)
yarga [219]
Y - 63 = 1/2 (x - 64)       (distribute 1/2)
y - 63 = 1/2x - 32          (add 63 to both sides)
y = 1/2x + 31                 (this is your answer)
