Answer:
h(t) = –16t^2 + 46*t + 6
Step-by-step explanation:
To quickly solve this problem, we can use a graphing tool or a calculator to plot the equation.
Please see the attached image below, to find more information about the graph
The projectile formula is
h(t) = -16*t^2 + v*t + h0
Where,
v = initial vertical velocity of the ball in feet per second
h0 = initial height of the ball in feet
We need to fill the equation
h(t) = –16t^2 + v*t + 6
Where
v is the missing speed
If we go through many values of v until we find the same graph as the one showed in the first picture, we can find that
v = 46 ft/s
Answer:
220 lifeguards
Step-by-step explanation:
We have to divide the length of the beach by the interval of the stationed lifeguards.
13.2 / 0.06 = 220 lifeguards
There are 220 lifeguards.
Ok hun from what i see i think its D :)
First, we want to find the difference in monthly fee and per minute costs.
20 - 15 = 5
0.25 - 0.05 = 0.20
So basically we now know that we need to make up for 5 dollars of monthly cost difference, and for every minute we talk with the two plans at the same time, it's different by 0.20.
Now, we just can divide 5 dollars by the difference of 0.20, which you would get 25 minutes from.
So you would have to talk for 25 minutes for the two plans to be the same cost.
Assuming that you used them at the same time, not just used B or A.
