Answer:
0.60, 2/3, 70%, 3/4, .85
Step-by-step explanation:
The distacne between the points (x1,y1) and (x2,y2) is

so the distance between (4,5) and (10,13) is
well, first
x1=4
y1=5
x2=10
y2=13
so



D=√100
D=10
the distance is 10 units
The quadratic equation that models the height of the rocket after t seconds is:
s(t) = -4.9t² + 39.2t.
<h3>What is the quadratic function for a projectile's height?</h3>
Considering the height in meters, the equation is given by:
s(t) = -4.9t² + v(0)t + h(0)
In which:
- v(0) is the initial velocity, in m/s.
- h(0) is the initial height, in m.
In this problem, we have that v(0) = 39.2, h(0) = 0, hence the equation is:
s(t) = -4.9t² + 39.2t.
