You take out a student loan for $80,000 with 2.75% annual interest to pay for your first year of college. This loan will cover a

yKpoI14uk [10]

Exponential growth equation would be

Amount= 80,000 (1+2.75/100) ⁴

At the end of 4 years I would have to repay an amount of $ 89,169.70

Step-by-step explanation:

Since, the amount is loaned it would vary exponentially i.e. in a compounding manner.

We know that for compound interest, the equation is written as-

Amount= principal(1+r/100) ˣ

Where r- rate of interest which is 2.75% annually

And x= time period= 4 years as in the question

Principal= $ 80,000

Therefore, Equation becomes-

Amount= 80,000(1+2.75/100) ⁴

On solving this Amount would equal $ 89,169.70

Hence, at the end of 4 years I would have to repay an amount of $ 89,169.70.

Constant of Proportionality

nadya68 [22]

Answer: The constant of proportionality is 8 for the the problem on your left! The constant of proportionality for the one on you right is 6! Hope this helps!

Step-by-step explanation: Vincent earned $24 for 3 hours and so you find out how much he gets paid for 1 hour, then you divide 24 by 3 and get 8! Later he earned $72 for 9 hours, and you do the same thing which is to divide 72 by 9 which also give you 8 and so your unit rate or constant of proportionality is 8. So for the other one Justene can bike for 12 miles in 2 hours and so you find out how many miles she can bike for 1 hours and so you divide 12 by 2 which give you 6 and she can bike 6 miles in 1 hour. Then she biked 36 miles in 6 hours and you divide 36 by 6 which give you 6 and so your constant of proportionality is 6!

Fantom [35]

Answer:
100 times bigger

Explanation:
The given number is:
35.3186

Let's take a look at the first 3 on the left (the one in bold).
We will find that this 3 is in the tens position (10)

Now, let's take a look at the other 3 (the one directly after the point).
We will find that this 3 is in the tenth position (0.1)

Now, when multiplying the digit in the tenth position by 100, this digit would be in the tens position.
This means that the difference between the two positions is 100

Based on this:
The 3 in the tens position is 100 times greater than the 3 in the tenth position.

Hope this helps :)
