Answer:
The ball reaches a height of 29.25 ft after 1.125 seconds
Step-by-step explanation:
The maximum height of a parabola can always be found by looking for the vertex. You can find the x value (or in this case the t value) of a vertex by using -b/2a in which a is the coefficient of x^2 and b is the coefficient of x.
-b/2a
-(36)/2(-16)
-36/-32
1.125 seconds
Now to find the height, we input that value in for t
h = -16t^2 + 36t + 9
h = -16(1.125)^2 + 26(1.125) + 9
29.25 feet
Answer:
![y = - x + 2](https://tex.z-dn.net/?f=y%20%3D%20%20-%20x%20%2B%202)
Step-by-step explanation:
![y = mx + b](https://tex.z-dn.net/?f=y%20%3D%20mx%20%2B%20b)
![y = \frac{ - 2}{2} x + 2](https://tex.z-dn.net/?f=y%20%3D%20%20%5Cfrac%7B%20-%202%7D%7B2%7D%20x%20%2B%202)
![y = - x + 2](https://tex.z-dn.net/?f=y%20%3D%20%20-%20x%20%2B%202)
Answer:
8 is the right answer
Step-by-step explanation:
in triangle swu,, wT bisect and perpendicular on su
so the triangle is isosceles triangle
therfore,Sw =, 8
Answer:
33
Step-by-step explanation
22 divided by 2 is 11
it says four years ago so add 11 and 4 and that equals 15
she is 15 right now. then add 22 which is 37 and subtract 4 which your answer would be 33
1 and 5/16 pounds
Divide 7/8 with 2/3
