Divide 331 by 4.5
331/4.5= 73.555555555555 so you can round to 73.6 mph
Answer:
The ball will take 2.6 seconds to hit the ground again.
Step-by-step explanation:
Sam kicks a soccer ball from the ground. The height of the ball (in feet) can be modeled with the function, h(t) = −16t(t − 2.6), where t is the time in seconds after the ball is kicked.
So, the ball will be at ground when h = 0 = - 16t(t - 2.6)
⇒ t = 0 or t = 2.6.
Therefore, the ball will take 2.6 seconds to hit the ground again. (Answer)
<h3>Part A</h3>
<u>Factoring the area:</u>
- 4x² + 20x + 25 =
- (2x)² + 2*2x*5 + 5² =
- (2x + 5)²
<u>The length of the side is:</u>
<h3>Part 2</h3>
<u>Factoring the area:</u>
- 4x² − 9y²=
- (2x)² - (3y)² =
- (2x + 3y)(2x - 3y)
<u>The sides of the rectangle are:</u>
Im pretty sure its A, but dont count on me!!! i hope it helps :/
