Answer:
- Interests charged for 4 years: $80
- Total amount to pay back:$480
Step-by-step explanation:
- To know the future value of an specific amount that is borrowed from a bank we use the following equation:
, where FV is future value, PV present value, n the amount of periods and i the interest rate. - In this particular case, the present value of the loan is $400, n=4 (4 years), i=5%. Then the future value equals:
. Then FV= $480, which is the total amount of money she would have to return in 4 years. - The interest paid can be calculated as the total amount paid ($480) minus the inicial loan ($400), which means that total interests paid= FV- PV= $80.
Answer:
330
Step-by-step explanation:
the change in hirght = 120 - 90 = 30
so 90 + (30 x 8)
= 90+240
= 330//
Answer:
$619.56
Step-by-step explanation:
Think ALOE: Assets = Liabilities + Owner's Equity (capital)
Assets- anything of value you own (+)
Add 400.25, 612.84, 58.72, 468.22
400.25 + 612.84 + 58.72 + 468.22
= 1540.03 (this is Zana's total assets and owner's equity - both sides of the aloe equation have to stay equal)
Owing someone is a liability, therefore subtract 807.58 and 112.89 from your assets and owner's equity
1540.03 - 807.58 = 732.45
732.45 - 112.89 = $619.56
Zana's capital is $619.56
Have a lovely rest of your day! :)
This one is so easy that your brain refuses to accept it.
It's looking for a harder answer, but can't find it !
You're totally correct, as far you went. x² + 2x does = -1
Now add ' 1 ' to each side: x² + 2x + 1 = 0
Can you factor that quadratic ?
Can you mash it through the quadratic formula ?
Actually, it's the simplest possible perfect square.
x² + 2x + 1 = (x + 1)²
So the solutions of x² + 2x + 1 = 0 are both x = -1 .
Don't say anything.
I know it's embarrassing.
