Answer:
D. the ball has been traveling for 5 seconds when it reaches the bottom of the ramp
Step-by-step explanation:
f(x) = x²- 10x + 25
We can factor this.
What 2 numbers multiply to 25 and add to -10
-5 *-5 = 25
-5+-5 = -10
f(x) =(x-5) (x-5)
Using the zero product property, we know that it will cross the axis at x=5
At 5 seconds f(x) =0. This means the height is zero at 5 seconds
5.7 kilograms = 5700 grams. You have to multiply the mass value by 1000 :)
(5.7 x 1000 = 5700)

Step 1: Find the slope
Slope formula = (y2 - y1) / (x2 - x1)
---You can choose any two points when finding the slope!
Point 1 = (-2,-10)
Point 2 = (-1,-3)
Slope = (-3 - - 10) / (-1 - - 2)
Slope = 7 / 1
Slope = 7
Step 2: Find the y-intercept
Now that we have the slope, we'll plug that and one point into slope-intercept form. Then, we'll solve for b.
Slope-Intercept Form: y = mx + b
---m is the slope, b is the y-intercept
Point = (-1, -3)
Slope = 7
-3 = 7(-1) + b
-3 = -7 + b
b = 4
Step 3: Put it all together
Now that we know the slope and y-intercept, all that's left to do is plug them into slope-intercept form.
Slope-Intercept Form: y = mx + b
Slope = 7
Y-Intercept = 4
Line: y = 7x + 4
Correct Answer: A
Hope this helps!
