Answer:
Step-by-step explanation:
I think the missing equation in your question is: h(t) = -16 + 16t + 480
Here is my answer:
As we know that the vertex form of a parabola, y=a + k where(h,k) is the vertex
h(t) = -16 + 16t + 480
= -16 ( + 480
= -16 + 484
So the vertex is ( , 484)
a. It take for Joseph second to reach his maximum height
b. The highest point that Joseph reached is the vertex of the function, it is 484 ft
c. Joseph hit the water after how many seconds?
<=> h(t) = 0
<=> -16 + 16t + 480 = 0
<=> t = second = 6 sec
Hope it will find you well
Answer:
10 days to complete
Step-by-step explanation:
for mixed rate problems, the sum of each individual reciprocal rates equals the sum of the combined rate
i.e
we are given,
A's rate = 15 days to complete
Combined rate = 6 days to complete
B's rate = need to find
substituting' the given info into the equation above,
1/15 + 1/ (B's Rate) = 1/6
1 / (B's Rate) = 1/6 - 1/15 (convert right side to same denominator)
1 / (B's Rate) = 5/30 - 2/30
1 / (B's Rate) = 3/30
1 / (B's Rate) = 1/10 (taking reciprocal of both sides)
B's rate = 10 days to complete
