First you need to find the Circumference
C = 2 pi r = 2 * 3.14 * 5.5 = 34.54

Arc measure / 360 = 7.7 / 34.54
Arc measure = 7.7 * 360 / 34.54
Arc measure = 80.25

Answer:
80.25 if you are using pi = 3.14
80.2 if you are using pi = 3.141592....

The population of a certain species of bird in a region after t years can be modeled by the function P(t)= 1620/1+1.15e^-0.042t
natka813 [3]

Answer:

A

Step-by-step explanation:

The function is  \frac{1620}{1+1.15e^{-0.042t}}

To find the maximum population, we need to set t towards infinity to get our answer.

So, we replace time with maximum (\infty). Let's check:

\frac{1620}{1+1.15e^{-0.042t}}\\=\frac{1620}{1+\frac{1.15}{e^{0.042t}}}\\=\frac{1620}{1+\frac{1.15}{e^{0.042(\infty)}}}\\=\frac{1620}{1+\frac{1.15}{\infty}}\\=\frac{1620}{1+0}\\=\frac{1620}{1}\\=1620

The population of birds approaches 1620 as t goes towards infinity. So we can say the max population of the species is 1620.

Correct answer is A

I need some help with this
marshall27 [118]
[-2 3] times [2
                    1] 

comes out to -2(2)+3(1) = -1.  Eliminate the first answer choice, due to 
                                                 the presence of that -7 instead of -1.

[-2 3] times [0
                    -3]

comes out to - 9.  This matches answer choices #2, #3 and #4.

[3,-4][2
           1]

comes out to 6-4, or 2.  Matches #2, #3, #4.


[3, -4][0
           -3]

comes out to +12, which matches answer choice #4.

Answer choice #4 is the correct one.

Review matrix multiplication if need be.  Feel free to ask questions here and now if need be.
