Answer: (4,-5)
Step-by-step explanation:
50=16t^2
Divide both sides by 16
3.125=t^2
Find the square root of both sides (approximated)
1.77= t
Final answer: F
Answer:
63
Step-by-step explanation:
so this question has 10 seats each takes 3 people 10*3=30 people
The bus also has 12 seats that can take 2 people 12*2=24 people
standing spaces=9
So the answer to this question would be 30+24+9=63
1) A parallel line has the same slope as this one y=-2x+5 whose slope is -2
So to find out which parallel line to y=-2x+5contains
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.
