18 - (-f) = 91
Subtracting a negative value changes to addition:
18 + f = 91
Subtract 18 from both sides:
F = 73

Answer:
0.300 30%
Step-by-step explanation:
Area circle 4^*pi =50.272
Area pentagon =area of the sum of 5 triangles
area of 1 triangle
(b*h)/2=
4.7* 3.2 divided into 2 =7.5
7.5*5 =37.5
subtract the area of the pentagon from the area of the circle:
50.272-37.5= 12.772
Divide the area remaining of the circle into the area of the whole circle to kow the probability:
12.772/50.272=0.254 (rounded to 0.300)

The first word of the question is cut out of the picture, so we don't exactly know what the assignment is. But we can see that the graph of f(x) will do something weird when x=-3, because the denominator will be zero, and division by zero doesn't even have a definition or meaning. Just for fun, you should go ahead and calculate the numerator when x=-3, and that totally blows your mind, because the numerator is zero too. So you've got. f(-3)= 0/0 , and I can pretty much guarantee that you won't be able to plot that point anywhere on the graph. (I'm pretty sure that f(-3) is actually going to turn out to be -13, but even if I'm correct, you probably haven't learned that little calculus trick yet, so don't worry about it. As far as you're concerned, f(-3) is 0/0, and can't be plotted.)
