Answer:
it came up to 28/31 which is 93%/ .90 so the answer is D. 0.90

Answer:
I see where you could be confused, i hope this will help

Yes!! the line AED is cut with a perpendicular line. The rule for perpendicular lines is that the angles made =90.
-This can also be proven by the fact that lines =180, 90+90=180
You have to add 23 and 45 will get 68 then divide 68 by 4 and that is your answer
Recognize that the given graph resembles the right half of a parabola that opens down. The general form of such a function is f(x) = -x^2. Next, see that the approx. vertex of the parabola is (0,88). This is the max value of the function. Thus, the general form of the function represented by this graph is g(x) = b - ax^2, where a is the coefficient of the x^2 term and b is the vertical intercept of the graph (equivalent here to the vertex of the graph).
Based upon this info, we must eliminate answer choices A and B.
Now we have to determine which answer choice, C or D, best models the graph. Note that P = 88 - (n/4)^2 is similar in form to P = 88 - ax^2, as pointed out earlier. Take a look at the graph, and draw a real or imaginary vertical line through x=n=10. Letting n=10 in 88 - (n/4)^2, we get 88 - (10/4)^2, or 88 - 4, or 84. Either this agrees with or does not agree with the value of the parabolic function shown in the graph. Does 88-4 = 80 seem to be represented by the graph for n = 10? I would say yes. So choose the answer C.
