Answer:
The maximum height is reached after 3.75 seconds.
Step-by-step explanation:
Assuming the deceleration due to gravity is unaided by air resistance, gravity causes the ball to lose vertical speed at the rate of 32 ft/s every second. The initial vertical speed of 120 ft/s will decline to zero when t satisfies ...
... 120 ft/s - (32 ft/s²)t = 0
... (120 ft/s)/(32 ft/s²) = t = 3.75 s
The ball will not go any higher after its vertical speed is zero.
880 is the answer for this arithmetic sequence
Mean number simply means average.
Just substitute it into the gradient formula which is: y2 - y1 / x2 - x1. So 2-3/2-9 = -1/-7 = 1/7
You have an equation and a table with the x value given.
Replace x in the formula with the x value in the table and solve for y.
y = x^2 + 1
y = (-3)^2 + 1 = 9+1 = 10
y = (-2)^2 +1 = 4+1 = 5
y = (-1)^2 +1 = 1+1 = 2
y = (0)^2 + 1 = 0+1 = 1
y = (1)^2 +1 = 1+1 = 2
y = (2)^2 +1 = 4+1 = 5
y = (3)^2 +1 = 9+1 = 10
