Answer:
Option B
Step-by-step explanation:
Slope
And
These are acceleration
Y intercept is (0,2) as x coordinate is 0
This is initial velocity 2m/s
The runner stopped at 8s
For this case we have the following variables:
t: time in seconds.
f (t): height as a function of time.
By the time Grace reaches the pool, the height is equal to zero.
We have the following table:
Time (t) (in seconds) Height f(t) (in meters)
1 25
2 20
3 15
4 0
We observe that the height is equal to zero after 4 seconds.
Equivalently:
Answer:
the following represents the x-intercept of f(t):
Grace reaches the swimming pool after 4 seconds
Answer:
y =-1/4x -8
Step-by-step explanation:
3x+12y=-96
Slope intercept form is y = mx +b where m is the slope and b is the y intercept
Subtract 3x from each side
3x -3x+12y=-3x-96
12y = -3x-96
Divide each side by 12
12y/12 = -3x/12 -96/12
y =-1/4x -8
