So you have to find the velocity (or first derivative) from the position function of h=-16t^2+48t+6
the velocity is -32t+48 which you then have to set equal to 0 in order to find t
-32t+48=0
-32t=-48
t=1.5
you then take your t value and sub it back into your original position function
-16(1.5)^2+48(1.5)+6 which will give you a maximum height of 42 feet
so the time it takes is 1.5 seconds to reach a maximum height of 42 feet
I can’t answer it without a picture of the graph
Answer:
7.25
Step-by-step explanation:
In the question, the term at least means less than or equal to is represented by ≥
Let the cost of each gift = c
He is buying gifts for 8 friends = 8 gifts
Hence, our Inequality equation is written as:
(c + $1.50)× 8 ≥ $70
8c + 12 ≥ 70
8c ≥70 - 12
c ≥ 58/8
c≥ 7.25
Therefore, the amount Claudio needs to spend on each gift in order to receive free shipping is 7.25
