Hey there,
<span>y = 90 + -45x + -10x2 + 5x<span>3
</span></span><span>-6x + -3x = -9x
y = 5(18 + -9x + 1x2 + -3x2 + x3)
</span><span> (-2 + x) * (3 + x)
y = 5(-2(3 + x) + x(3 + x))(-3 + x)
y = 5((3 * -2 + x * -2) + x(3 + x))(-3 + x)
y = 5((-6 + -2x) + x(3 + x))(-3 + x)
y = 5(-6 + -2x + (3 * x + x * x))(-3 + x)
y = 5(-6 + -2x + (3x + x2))(-3 + x)
</span>y = 90 + -45x + -10x2<span> + 5x</span><span>3=
</span><span> 10 15
115+-45=70
X=70
</span>
X+x+10+2(2x+10) = 180
2x + 10 + 4x+20 = 180
6x + 30 = 180
6x = 150
X = 25
Plug in 25 to find angle

Answer: the total amount that you can earn in 15 years is $737245. Option C
Step-by-step explanation:
You receive an annual salary of $32,900 and each year, you are assured of a 5.5% raise. Assuming there was no raise, you get 100% of your previous salary each year. With a raise of 5.5%, you will get 100 + 5.5 = 105.5% of your previous salary for each year. This is a geometric progression and we want to determine the sum of 15 terms(15 years).
The formula for the sum of terms in a geometric progression is
Sn = [a(r^n - 1)]/ r - 1
Sn = sum of n terms
a = the first term
n = number of terms
r = common ratio
From the information given,
a = 32900
n = 15
r = 105.5/100 = 1.055
S15 = [32900(1.055^15 - 1)] / 1.055 - 1
S15 = [32900(2.23247649 - 1)] / 0.055
S15 = 32900 × 1.23247649) / 0.055
S15 = 737245.0277
S15 = $737245
