We have been given that Sarah invests her graduation money of $1,750 in an annuity that pays an interest rate of 6% compounded annually. We are asked to write an exponential function for her investment growth.
We will use compound interest formula to solve our given problem.
, where
A = Final amount after t years,
P = Principal amount,
r = Annual interest rate in decimal form,
n = Number of times interest is compounded per year,
t = Time in years.
Since interest is compounded annually, so .
Therefore, the function describes Sarah's investment growth.
I think this is how you solve this
We can think of it as being 6 congruent triangle whose vertices are at the center of the hexagon so it will map onto itself 6 times
Answer:
Step-by-step explanation:
let x be apple juice and y be orange juice
12 = x + y
x = 12 - y
15 = 1x + 1.5y
x = 15 - 1.5y
set the equations as equal
12 - y = 15 - 1.5y
solve for y
12 + .5y = 15
.5y = 3
y = 6, you bought 6 bottles of orange juice
so, 12 = x + 6 , x = 6 , you bought 6 bottles of apple juice
