Answer:
4 seconds.
Step-by-step explanation:
The given equation is
where, h is height in feet of a golf ball above the ground after being hit into the air and t is the number of seconds elapsed since the ball was hit.
We need to find the time for the ball to hit the ground.
At ground level the height of ball is 0, i.e., h=0.
Using zero product property, we get
Therefore, it will take 4 seconds for the ball to hit the ground.
Answer: D
The relation represents _y_ as a function of x, because each value of _x_ is associated with a single value of _y_.

Answer:
b
Step-by-step explanation:
The tangent- secant angle 55° is equal to half the difference of its intercepted arcs, that is
(170 - x) = 55 ( multiply both sides by 2 to clear the fraction )
170 - x = 110 ( subtract 170 from both sides )
- x = - 60 ( multiply both sides by - 1 )
x = 60 → b
