Answer:
cosR = 
Step-by-step explanation:
assuming the right triangle has ∠ Q = 90° with legs 5 and 12
then this is a 5- 12- 13 right triangle with hypotenuse PR = 13 cm
then
cosR =  =
 =  =

Answer:
   {2.96, 12.66}
Step-by-step explanation:
A graph shows the rocket will be 600 feet up after 2.96 seconds, and again at 12.66 seconds.
__
You can solve the equation h = 600 to find the times.
   -16t^2 +250t = 600
   -16(t^2 -15.625t) = 600
   -16(t^2 -15.625t +7.8125²) = 600 -16(7.8125²)
   -16(t -7.8125)² = -376.5625
   t -7.8125 = √(376.5625/16) ≈ ±4.8513
   t = 7.8125 ± 4.8513 ≈ {2.9612, 12.6638}
The rocket will be 600 ft above the ground 2.96 and 12.66 seconds after launch.
