h(t) is the height of the diver in feet above the water
Now it asks about the time at which diver reaches the water
When diver reaches the water , the height of diver from water should be zero
So we plug h(t) =0
So
divide whole equation by -16
we can now factor the quadratic equation
So we get
(t+4)(t-3) =0
plug each factor equal to zero and solve for t
t+4 =0 and t-3 =0
So t=-4 and t=3
Now time cannot be negative , So t=3
So time = 3 seconds
It takes 3 seconds for the diver to reach the water
<u>Given</u>:
The coordinates of the triangle JKL are (1,2),(4,2) and (3,5)
We need to determine the coordinates of the triangle J'K'L' rotated 360° clockwise with the origin.
<u>Coordinates of the triangle J'K'L':</u>
The rule to rotate the triangle 360° clockwise with the origin is given by
The coordinates of the point J' is given by
The coordinates of the point K' is given by
The coordinates of the point L' is given by
Therefore, the coordinates of the triangle J'K'L' are (1,2), (4,2) and (3,5)
Hence, Option D is the correct answer.
