The ball takes 6 seconds to reach the ground.
<u><em>Explanation</em></u>
Height of the ball after seconds is represented by....
The height of the ball is 0 feet when it hits the ground. So, for finding the number of second the ball takes to reach the ground, <u>we will just plug into the above equation and then solve for .</u>
Thus...
Using zero-product property....
and
(Negative value is ignored as time can't be negative)
So, the ball takes 6 seconds to reach the ground.
8 + 0.4 + 0.07 + 0.008 is your answer. But all you had to do is separate your numbers with working on the biggest number to the smallest number.
Answer:
Step-by-step explanation:
y=mx+b
m=(y2-y1)/(x2-x1)
m=(90-65)(/(200-100)=25/100=1/4
y=x/4+b, using point (100,65)
65=100/4+b
65=25+b
b=40
y=x/4+40 or more neatly
y=(x+160)/4
Following these steps you should have no problem with second problem.
