Use an algebraic equation to find the measures of the two angles described below. Begin by letting x represent the degree measur
Romashka [77]

Answer:

Step-by-step explanation:

For two angles x and y to be supplementary, the sum of the angles must be 180°

x+y = 180

x = 180-y... 1

If the measure of the angle is five times greater than its supplement this is expressed as:

x = 5y…. 2

Substitute equation 2 into 1

5y = 180-y

5y+y = 180

6y = 180

y = 30°

Hence the measure of the supplement is x = 5y

x = 5(30)

x = 150°

Find the accumulated value of an investment of $14,000 at 10% compounded semiannually for 11 year
kifflom [539]

Given:

Principal = $14000

Rate of interest = 10% compounded semiannually.

Time = 11 years.

To find:

The accumulated value of the given investment.

Solution:

Formula for amount or accumulated value after compound interest is:

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

Where, P is the principal values, r is the rate of interest in decimal, n is the number of times interest compounded in an year and t is the number of years.

Compounded semiannually means interest compounded 2 times in an years.

Putting P=14000,r=0.10,n=2,t=11 in the above formula, we get

A=14000\left(1+\dfrac{0.10}{2}\right)^{2(11)}

A=14000\left(1+0.05\right)^{22}

A=14000\left(1.05\right)^{22}

A\approx 40953.65

Therefore, the accumulated value of the given investment is $40953.65.
