Answer:
477 yards
Step-by-step explanation:
1 foot to a yard is 0.333333.
1431 times 0.333333=477yards
Answer:
810 ft³
Step-by-step explanation:
The given
equation in this case is:
<span> y = -16 t^2 + 400</span>
We can see
that the slope of the equation is negative (-16) which means that the position
of Kay is on the positive y-axis , while the bottom of the river is in the
origin. This is supported by taking t = 0, the initial y becomes y = 400.
Therefore the position of Kay now is at (0, 400).
So to find
for the time when the camera hits the water, then y must be zero (t, 0) so we
have to find for t in this case.
When y = 0
0 = -16 t^2
+ 400
16 t^2 = 400
t^2 = 25
t = 5 s
<span>Therefore it
takes 5 seconds for the camera to hit the water and for Kay to see a splash.</span>
