Answer:
35 m/s
Step-by-step explanation:
Let gravitational acceleration g = 9.8m/s2. We can calculate the amount of time for the ball to fall vertically a distance of 1.6 m



This is also the time it takes for the ball to fly horizontally, assume constant horizontal speed, we can calculate the speed it takes to travel across 20m in 0.571s
v = 20 / 0.571 = 35 m/s
Answer:
so where are the 3 consecutive numbers?
The equation for working out the slope of a linear line is:
, where x and y are the coordinate pairs.
So just pick two of the purple dots on the graph and fill in the equation.
I'll pick the dot that's (-4, 1) and (4, -7).
Now I just do
, which is just
when simplified.
Answer:
6u^3
Step-by-step explanation:
Answer:
y = (-13/11)x - 5/11
Step-by-step explanation:
Where's the list of equations from which you're to choose?
The line that connects points (-8 ,9) and (3, -4) has the following slope:
9 - (-4)
m = ----------------- = -13/11
-8 - 3
Then the new line with this slope is y = (-13/11)x + c
and because (-8, 9) satisfies this equation, 9 = (-13/11)(-8) + c, and we need to calculate c from this. 9 = 104/11 + c, or
-c = 104/11 - 99/11, or - 5/11
Then the desired equation is y = (-13/11)x - 5/11
