Answer:
66.14inches
Step-by-step explanation:
pyhtgreom therom
75^2+b^2 = 100^2
5625 + b^2 = 10,000
subtract both sides by 5625
b^2 = 4375
square root both sides
b = 66.14
I'm not 100% sure if I am right, but for number 9 you would pick two points on , let's just say you pick points (0, 1) and (2, -2). Then you would find those points in the table. So in this case the answer would be D. And I'm not really sure how to explain #10 but you basically work out each problem with the graph to see if it makes sense. For example if you try working out problem F it wouldn't make sense since you start of with 10 dollars and earn 2 each day. But on the graph it shows that you are loosing two. Sorry if I didn't explain it right, if you have more questions let me know!
