Answer: it will take 36 years for the account balance to reach $1,200.
Step-by-step explanation:
We would apply the formula for determining compound interest which is expressed as
A = P(1+r/n)^nt
Where
A = total amount in the account at the end of t years
r represents the interest rate.
n represents the periodic interval at which it was compounded.
P represents the principal or initial amount deposited
From the information given,
P = 70
A = 1200
r = 1.5% = 1.5/100 = 0.015
n = 1 because it was compounded once in a year.
Therefore,.
1200 = 700(1 + 0.015/1)^1 × t
1200/700 = (1.015)^t
1.714 = 1.015^t
Taking log of both sides,
Log 1.714 = log 1.015^t
0.234 = tlog 1.015 = t × 0.0065
t = 0.234/0.0065
t = 36 years
The answer is A: square root.
If she knows the area is x feet squared, then you have to find the square root of the number, to find the side length. Hope that helps!
Answer: The answer is 14 units I believe.
Answer:
-3.786 × 10^7
Step-by-step explanation:
Put an decimal behind a number 1-10
but keep the negative sign
so you should get
-3.7860000
Then you count how many numbers are to the right of the decimal which is 7.
That number will become the exponent and then you take away the zeros
You should then have
-3.786 × 10^7 as your answer.
