For this case we have an equation of the form:
h (t) = (1/2) * a * t ^ 2 + vo * t + h0
Where,
a: acceleration
vo: initial speed
h0: initial height
t: time
We have then that the equations:
h (t) = - 16t ^ 2 + 19t + 110
Therefore, the initial velocity is given by:
vo = 19 feet / s
Answer:
The initial velocity when the rock is thrown is:
vo = 19 feet / s
150 = 1*150 = 2*75 = 3*50 = 5*30 = 6*25 = 10*15
Your numbers are 15 and 10.
Answer:
9:17 P.M.
Step-by-step explanation:
If the drive is 2 hours and 45 minutes and they need to be there by 12:02 am, you subtract two hours from that number. This means that if the drive was only two hours, they would have to leave home at 10:02 pm. However, it is 45 minutes longer than that so you have to subtract 45 minutes from 10:02 pm which gets 9:17 pm. Hope this helps!
The transformation is a reflection in the line
followed by a reflection in the line
.
The mapping for a reflection in the line
is
.
That is simply swapping the coordinates.
Now we reflect the resulting coordinates in the line
which has the mapping
So we transform the resulting coordinates as follows:
Hence we have
