A car factory can build 14 cars in 4 hours. How many cars can it build in 7 hours?

1 answer:

3 0

You can do rate. 14 divided by 4 equals 3.5. A car factory can build one car in 3.5 hours. 3.5 multiply by 7 equals 24.5.

Answer:

$g(t) = -16t^2+80t$ .

Step-by-step explanation:

We are given that $v=80$ and $h=0$ (because that's the ground), so substituting that into $g(t) = -16t^2+vt+h$ gives $g(t) = -16t^2+80t$ .

Part (b)

We use the result of part (a) and plug in (x,y) = (0,0). This is directly from the initial condition y(0) = 0.

$\arcsin(4y) = x^2 + C\\\\\arcsin(4*0) = (0)^2 + C\\\\\arcsin(0) = C\\\\0 = C\\\\C = 0\\\\$

-----------------

This means,

$\arcsin(4y) = x^2 + C\\\\\arcsin(4y) = x^2 + 0\\\\\arcsin(4y) = x^2\\\\4y = \sin(x^2)\\\\y = \frac{1}{4}\sin(x^2)\\\\$

is the solution with the initial condition y(0) = 0.
