<span>f(x)=5(x+4)^3/2, let y = f(x).
</span>
<span>y =5(x+4)^3/2. The y intercept is value of y when x = 0
y intercept = </span><span>5(0+4)^3/2 = 5* 4^3.2 = 5*6 = 30. Use your calculator.
y intercept = 30

48.9 / 4 = 12.225
distance = 100m
time = 12.225 sec
v = d/t
The answer is 8.1799
ok that is easy but it is sideways so I cant read it well I am dislexic
