Answer:
The ball will take approximately 2.165 seconds.
Step-by-step explanation:
The height of the ball is represented by the function , the time taken by the ball to hit the ground is a value of such that , we proceed to solve the following equation for :
(1)
The ball will take approximately 2.165 seconds.
4y+80=180
i think it's like this

x=-11
Step-by-step explanation:
Answer:
200+2w>400 and w>100.
Step-by-step explanation:
The perimeter of a rectangle can be found using 2*l + 2*w = P. If the length is 100 cm then 2(100)+2w > 400. Simplified this is 200+2w>400.
You can solve for the width and you find
200+2w>400
2w>200
w>100.
Answer:
The answer would be 18
Step-by-step explanation:
the formula for area of a triangle is 1/2b*h
so would mulitply 3*3 and get 9/2 which would be 4.5 do that on the otherside and you would get 4.5 again add together and you would get 9
for the square you would calculate the area by multplying b*h to get 9 so 9+9=18
