Answer:
440cm²
Step-by-step explanation:
*Area= (a+b)/2×h
(19+25)/2*20
= _ * 440cm². *_
By solving a quadratic equation, we will see that the ball hits the ground after 2.6 seconds.
<h3>How long does it take for the ball to hit the ground?</h3>
Here we need to solve the equation:
h(t) = 0 = -16t² + 40t + 4
This represents that the ball hits the ground.
So we just need to solve that quadratic equation, using the general formula we get:
We only care for the positive solution, which is:
t = (-40 - 43.1)/-32 = 2.6s
So the ball hits the ground after 2.6 seconds.

Answer:
your answer is 15/4. have fuun
Answer:
Yes
Step-by-step explanation:
Using the Pythagorean theorem, you would square 8, 15, and 17. 8^2 is 64. 15^2 is 225. If you add those, you get 289. Now, 17^2 is 289. Because 289=289, it is a square triangle.
