PLEASE HELP Kristina invested $2,500 in a brokerage account that is expected to appreciate at a rate of 9% per year. How long will it take her investment
to be worth $25,000. Make sure to show your work for each question.
a.) Does this situation represent growth or decay? (1 pt.)
b.) Write the explicit function that models the situation. (2 pts.)
c.) Use your model and logarithms to calculate the number of years it will take for the value to reach $25,000. Round to the nearest tenths
place if necessary. (2 pts.)

step-by-step explanation:

c: y > - 1/6x + 1

step-by-step explanation:

dashed line - meaning this < or > also not equal

solid line - meaning this < or > also equal

your answer is c because y > means up & it's shaded up, but y < means down

hope this ! : )

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional
