We have been given that Clare made $160 babysitting last summer. She put the money in a savings account that pays 3% interest per year. If Clare doesn't touch the money in her account, she can find the amount she'll have the next year by multiplying her current amount 1.03.
We are asked to write an expression for the amount of money Clare would have after 30 years if she never withdraws money from her account.
We will use exponential growth function to solve our given problem.
An exponential growth function is in form 
, where
y = Final value,
a = Initial value,
r = Growth rate in decimal form,
x = Time.
We can see that initial value is $160. Upon substituting our given values in above formula, we will get:
To find amount of money in Clare's account after 30 years, we need to substitute 
in our equation.
Therefore, the expression 
represents the amount of money that Clare would have after 30 years.
The formula to solve these is the square root of X x Y, So the problem would be 242 * 8 which = 1,936. Then you find the square root of 1,936 which = 44 . So that is your answer :) Hope it helps
-3 + 8i is in quadrant II
4i is on the vertical axis
6 is on the horizontal axis
5 - 2i is in the quadrant IV

Answer:
Therefore he paid $10440 in 4 year.
Step-by-step explanation:
Given, Rachit borrowed $15000 from his friend. He gave $3000 at the rate 15% for 4 year.
Interest(I₁)= Prt here P= $3000, r=15% and t = 4 year
=$(3000×0.15×4)
=$1800
He gave $(15000-3000)= $12000 at the rate of 18%.
Interest(I₂)= Prt here P= $12000, r=18% and t = 4 year
=$(12000×0.18×4)
=$8640
Therefore he paid =$(1800+8640)=$10440 in 4 year.
