Answer:
See explanation. I added a photo and tried to explain everything. Please tell me in the comments if I explained it well and if handwriting was ok :)
Step-by-step explanation:
1.4•1.58= 2.212 is your answer because if it cost 1.58 per pound and it is 1.4 lbs your answer will be 2.212
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.
