Answer:

-4°C

Key:

( | | ) = these in between numbers is the absolute value. EXAMPLE: |-8| = 8

Step-by-step explanation:

If it was -9°C and it INCREASED by 5°C, you need to ADD.

-9°C + 5°C

*Because -9°C is a NEGATIVE NUMBER and is on the LEFT side of the number line, unlike 5°C, you need to count 5 units to the RIGHT of -9°C (Basically subtract the absolute values of each number (-9 = |9|) (5 = |5|) and make it either positive or negative, depending on which absolute value is the greatest (|9|).*

-9°C + 5°C OR |9| - |5|

|9°C| - |5°C| = |4°C| = -4°C

(because the greatest absolute value, |9|, is negative, the answer is too.)

How much money should be deposited today in an account that earns 6% compounded monthly so that it will accumulate to $1000000 (

aleksandr82 [10.1K]

Answer:

The principal investment required to get a total amount of $ 1,000,000.00 from compound interest at a rate of 6% per year compounded 12 times per year over 45 years is $ 67,659.17.

Step-by-step explanation:

Given

Accrued Amount A = $1000000

Interest rate r = 6% = 0.06

Time period t = 45 years

Compounded monthly n = 12

To determine:

Principle amount P = ?

Using the formula

$A\:=\:P\left(1\:+\:\frac{r}{n}\right)^{nt}$

$P\:=\frac{A}{\left(1\:+\:\frac{r}{n}\right)^{nt}}$

substituting A = 1000000, r = 0.06, t = 45, and n = 12

$P\:=\frac{1000000}{\left(1\:+\:\frac{0.06}{12}\right)^{12\cdot 45}}\:$

$=\frac{1000000}{1.005^{540}}$

$P = 67659.17$ $

Therefore, the principal investment required to get a total amount of $ 1,000,000.00 from compound interest at a rate of 6% per year compounded 12 times per year over 45 years is $ 67,659.17.
