Answer:
Below in BOLD.
Step-by-step explanation:
h(t) = -0.2t^2 + 2t
We can find the maximum height and the time by converting to vertex form:
h(t) = -0.2(t^2 - 2t)
= -0.2[(t - 1)^2 - 1)
= -0.2(t - 1)^2 + 0.2
The time to get to maximum height = 1 second and the maximum height is 0.2 m.
When the ball reaches the ground h = 0 so
-0.2(t - 1)^2 + 0.2 = 0
(t - 1)^2 = -0.2 / -0.2 = 1
t - 1 = 1
t = 2 seconds.
Answer:
Step-by-step explanation:
the tangent of an angle is equal to the opposite side length over the adjacent side length
tan(P) = 3/5 = 0.6
Answer:
y = 3x +21
Step-by-step explanation:
m= 3
The y-intercept of the line that passes through the given point (-7,0) is
0 = -7(3) + b
b= 21
The equation of the line that passes through the given point (-7,0) is
y =mx +b
y = 3x +21
Answer:
-25
Step-by-step explanation:
You can take 10÷-⅖=-25
To figure this out just multiply:
6 people had 3 servings = 6 x 3
6 x 3 = 18 There's your answer!
