Answer:
y = -1x -3
Step-by-step explanation:
Check the pictures below.
if we knew the roots/solutions of the equation, we can set h(s) = 0 and solve for "s" to find out how many seconds is it when the height is 0.
if you notice in the first picture, when f(x) = 0, is when the parabola hits a root/solution or the ground, for David he'll be hitting the water surface, and the equation that has both of those roots/solutions conspicuous is
h(s) = -4.9(s - 2)(s + 1).
The arrival time in london of a train that leaves Leicester to london at 11:50 A.M is 13:05 pm.
To calculate the arrival time in london of a train that leaves Leicester to london at 11:50 A.M, use use the formula below.
Formula:
- Ta = [(d/s)+11:50]....... Equation 1
Where:
- Ta = Arrival time
- d = distance from Leicester to London
- s = Speed
From the question,
Given:
Substitute these values into equation 1
- Ta = [(100/80)+11:50]
- Ta = 1.25h+11:50
- Ta = 1 hours 15 minutes +11:50
- Ta = 13:05 pm
Hence, the arrival time in london of a train that leaves Leicester to london at 11:50 A.M is 13:05 pm.
