A.) y = ut - 1/2gt^2 + 12
y = 6t - 1/2(9.8)t^2 + 12
y = 6t - 4.9t^2 + 12
b.) The y-intercept is 12
c.) The y-intercept represent the height of the ball at time t = 0
d.) At the time the ball reaches the ground, y = 0
-4.9t^2 + 6t + 12 = 0
t = 2.29 seconds
Therefore, it took the ball 2.29 seconds to reach the ground.
<h2>
B)</h2>
It is <em><u>400</u></em>. Since 5 x 8 = 40 add the 0 to the end its 400!!
Hope this helps <33!!
Answer: try multiplication for the answer or use photomath
Step-by-step explanation:
Andrew walked for 3/4 miles after his break
<h3>
How to calculate the number of miles Andrew walked after the break ? </h3>
Andrew went for a walk
The trail he took is 1 1/4 miles long
He walked for 1/2 miles before stopping for a water break
After the break, he continued the journey
He continued the journey without stopping
The distance Andrew walked after his break can be calculated as follows
5/4 - 1/2
= 5-2/4
= 3/4
Hence Andrew walked for 3/4 miles after taking the break
