Two angles are supplementary when they add up to 180 degrees ⇒
m∠1 + m∠2 = 180°
4y + 7 + 9y + 4 = 180
13y + 11 = 180
13y = 180 - 11
13y = 169
y = 169/13
y = 13

m∠2 = 9y + 4 = 9 * 13 + 4 = 121°

Say you have $14,000 to invest into an investment account. You can either invest your money into an account with a 7% annual int

taurus [48]

Answer:

You should choose an account with a 7% annual interest rate which is compounded quarterly

Step-by-step explanation:

we know that

The compound interest formula is equal to

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

where

A is the Final Investment Value

P is the Principal amount of money to be invested

r is the rate of interest in decimal

t is Number of Time Periods

n is the number of times interest is compounded per year

part 1)

we have

$t=15\ years\\ P=\$14,000\\ r=0.07\\n=4$

substitute in the formula above

$A=14,000(1+\frac{0.07}{4})^{4*15}$

$A=14,000(1.0175)^{60}$

$A=\$39,645.43$

part 2)

we have

$t=15\ years\\ P=\$14,000\\ r=0.068\\n=12$

substitute in the formula above

$A=14,000(1+\frac{0.068}{12})^{12*15}$

$A=14,000(1.0057)^{180}$

$A=\$38,713.11$
