Answer:

∠ CBA = 67°

Step-by-step explanation:

∠ BAD = 90° ( angle in a semicircle )

The sum of the 3 angles in the triangle = 180° , that is

∠ CBA + 90° + 23° = 180°

∠ CBA + 113° = 180° ( subtract 113° from both sides )

∠ CBA = 67°

Question 10 (7 points) d Elizabeth borrowed $20,000 for five years at a 5% annual interest rate, what is her monthly payment, to

zhenek [66]

Answer:

monthly payment is $377

C is the correct option.

Step-by-step explanation:

The formula for the monthly payment is given by

$C=\frac{Prt(1+r)^n}{(1+r)^n-1}$

Given that,

P = $20,000

n = 5 years = 60 months

r = 0.05

Substituting these values in the formula

$C=\frac{20000\cdot \frac{0.05}{12}(1+\frac{0.05}{12})^{60}}{(1+\frac{0.05}{12})^{60}-1}$

On simplifying, we get

$C=\$377.425\\\\C\approx \$377$

Therefore, the monthly payment is $377

C is the correct option.
