Answer:
t = 4.5 seconds
Step-by-step explanation:
It is given that, a golfer hits a ball from a starting elevation of 4 feet with a velocity of 70 feet per second down to a green with an elevation of −5 feet.
The number of seconds t it takes the ball to hit the green can be represented by the equation as follows :
......(1)
We need to find time taken by the ball to land on the green. Solving the quadratic equation (1) we get :
t = -0.125 s and t = 4.5 s
Ignoring t = -0.125 s, we get the time taken by the ball to land on the green is 4.5 seconds.
<h3>The common ratio of the sequence is -3</h3>
<em><u>Solution:</u></em>
<em><u>Given sequence is:</u></em>
-2, 6, -18, 54
We have to find the common ratio of sequence
Common ratio is the ratio between two consecutive numbers in the sequence
<em><u>Find the ratio of a term to its previous term</u></em>
Thus the common ratio of the sequence is -3
