Explanation:

⇒ (a + b)²

⇒ (a + b)(a + b)

Answer:

In 4 years, you will have $2,635.38

Step-by-step explanation:

The formula for annual compound interest, including principal sum, is:

A = P (1 + r/n) ^ (nt)

Where:

A = the future value of the investment/loan, including interest

P = the principal investment amount (the initial deposit or loan amount)

r = the annual interest rate (decimal)

n = the number of times that interest is compounded per year

t = the number of years the money is invested or borrowed for

Note that this formula gives you the future value of an investment or loan, which is compound interest plus the principal. Should you wish to calculate the compound interest only, you need this:

Total compounded interest = P (1 + r/n) ^ (nt) - P

Use inverse operations and properties of equality to isolate the variable m+31=307
otez555 [7]

ANSWER

m = 276

EXPLANATION

The given equation is

m + 31 = 307

We add the additive inverse of 31 which is -31 to both sides of the equation to get,

m + 31   +  - 31= 307 +  - 31

Simplify;

m +0= 307 - 31

m = 276

Which quadrant contains -11pi/18 and what is the reference angle?
vekshin1

Answer:

Option 1 is correct.

Step-by-step explanation:

Given angle \frac{11\pi}{18}. we have to find the quadrant and the reference angle.

Angle given is \frac{11\pi}{18} i.e \frac{11}{18}\times 180^{\circ}=110^{\circ}

Hence, the angle is 110° lies in second quadrant.

Now reference angle, the smallest angle that you can make from the terminal side of an angle with x-axis.

which is \pi-\frac{11\pi}{18}=\frac{7\pi}{18}

Hence, option 1 is correct.
