It is 50% because it is half of the total
1. First calculate the positive root of the quadratic using your preferred formula. I got a solution
. That gives you the distance the ball traveled from d=0 (small hill). So the answer is A.
2. The domain is [0,2.121...]. The range is from 0 to the max height. The d for which the ball is the highest is given by the formula x = -b / 2a = -3.3/(-3.2) = 1.031... so the max is 1.902... So the range is [0,1.902...] So the answer is C.
Step-by-step explanation:
In my opinion Option A is the correct answer because
Product of 3 and x = 3x
7.5 more than that = 3x + 7.5
Answer:
B!
