Answer:
B. 2.9
Step-by-step explanation:
3(2y - 0.3) = 19.4 - y
An easier way to find y is to try using all of your answer choices. For example, let's try using our answer choice, B.
3(2 × 2.9 - 0.3) = 16.5
19.4 - 2.9 = 16.5
Now, we have our answer, B. 2.9.
Answer:
Part A: the answer is $3.70 (A)
Part B: the answer is $38.60 (D)
Step-by-step explanation:
If the arrow is in the air, then when it hits the ground, h(t)=0. So:
0=-16t²+63t+4
16t²-63t-4=0
(16t+1)(t-4)=0
t= -1/16 or 4
Using the positive result of 4, we get t=4 seconds as the time the arrow was in the air
