Answer:

Correct choice is B

Step-by-step explanation:

The exponential regression model can be written as exponential function

$y=a\cdot b^x.$

Then

$5,000=a\cdot b^0=a,\\ \\5,510=a\cdot b^2\Rightarrow 5,510=5,000\cdot b^2,\\ \\b^2=\dfrac{5,510}{5,000}=\dfrac{551}{500}\Rightarrow b\approx 1.05.$

Thus,

$y=5,000\cdot (1.05)^x.$

When $x=12,$ you get

$y(12)=5,000\cdot (1.05)^{12}\approx \$8,980.$

How do I find the measurements of this triangle

Rudik [331]

Using sine law:

9/sinc = 15/sin22

sinc = 9sin22 / 15 = 0.225

so c = sin^-1(0.225) = 12.99 degrees ~~ 13 degrees

if B was required:

B = 180 - C - A ~~ 145
