<span>Given:
s=4m/s
t=2m
d=?
Convert
1min=60sec
2 min x 60 sec / 1min = 120 sec
d=vt
= 4m/s * 120s
= 480 m
Example:
The given terms here are: Distance = 150 km Time = 7200 s Speed =? To express the speed in appropriate units, in this given we can simply kilometer to meter which is the SI unit for distance. Hence, we do the conversion first. </span><span><span>
1. </span>Conversion</span><span> 150 km = m? 1 km = 1000 m 150 km x 1000 m / 1 km = 150, 000 m </span><span><span>
2. </span>To find speed, we drive the formula d = vt where v = velocity or speed to v= d/t</span>
<span>V = d / t </span>
<span>V = 150, 000m / 7200 s </span>
<span>V = 20.83 m/s </span>
Hence, 20. 83 m/s is the speed.<span>

Answer:
f(x)= -2(x-8)²+6
Step-by-step explanation:
First graph the points
you will get a parabola that has a vertex in (8,6) wich means h= 8 and k=6
so the equation is
to get a we will replace by the coordinates of a point for example (6,-2)
- -2 = a(6-8)²+6
- -2 = a*4+6
- -2-6 = 4a
- -8 = 4a
- a = -2
a is negative wich makes sense since the parabola opens down
Answer:
Step-by-step explanation:
X = -4 – -2 = -2
Y = 4 – 10 = -6
Equation of the line:
y = 3x + 16
When x=0, y = 16
When y=0, x = -5.3333333333333
