It is 2/13. Divide number and denominator by 8.
Answer:
y = 1/40x + 20
Step-by-step explanation:
Slope-intercept equation format:
y = mx + b
m = slope/ gradient/ constant of variation/ rate of change
b = y-intercept
To find the slope, use the formula:
Find two random points:
1 - (0.5, 40) , 2 - (1, 60)
Plug in:
Solve:
Divide:
The y-intercept is when the x-coordinate is equal to 0.
The y-intercept is always the beginning.
So observing the graph, the first point is (0, 20)
The x-coordinate is 0.
Y intercept = 20.
Plug in both slope and y-intercept:
y = 1/40x + 20
Answer:
Any projectile that is under the rules of gravity can be modeled by a parabola!
Picture a football player kicking the ball up: it will follow a parabolic orbit, <u>and the vertex is the highest point it will reach.</u>
Picture a roller coaster: it will most likely follow a parabolic orbit, with the vertex being that scary moment on the top of the roller coaster track.:)
From the equations given above, you can graph them by the slope and the y-intercept. I will be solving this by substitution method. It will be giving the same values as with graphing. We do as follows:
-2x + 30 <span>= -x + 21
-x = -9
x = 9
y = -9+21 = 12
Hope this helps. Have a nice day.
