Answer:

Option D [ $y=6.61\,*\,1.55^x$ ] in the list of possible answers

Step-by-step explanation:

For this problem you are supposed to use a calculator that allows you to do an exponential regression. There are many tools that can help you with that, depending on what your instructors has assigned for your class.

I am showing you the results of a graphing tool I use, and which after entering the x-values and the y-values in independent "List" forms, when I request the exponential regression to fit the data, I get what you can see in the attached image.

Notice that the exponential of best fit with my calculator comes in the form:

$y=A\,e^{k\, x}$

with optimized parameters:

$A \approx 6.6114\,\,\,and\,\,\, k=0.4378321$

Notice as well that since:

$e^{0.4378321} \approx 1.5490$

the exponential best fit can also be written:

$y=6.611403\,\,*\,e^{0.4378321\, x}=6.611403\,*\,1.549^{\,x}$

and this expression is very close to the last option shown in your list of possible answers

Two angles are supplementary if their sum is 180 degrees. One angle measures three times the measure of a smaller angle. If X re

Mkey [24]

So 3 times the measure of a small angle

3x + x= 180

4x = 180
X= 45

3(45) + 4(45) = 180

Hope this helps!

Step-by-step explanation:

$\text{The yellow area is half of the area of the square minus the area of the circle.}\\ \\ A_s=6^2=36\\ \\ A_c=\pi r^2=\pi 3^2=9\pi \\ \\ A_y=\frac{1}{2}(36-9\pi)\approx 3.9in^2$
