Answer:
She is incorrect; Paloma's ratio of seconds travelled to feet travelled is 1:10.
Step-by-step explanation:
Her ratio is 1:10 because the first number is the number of seconds, and the second number is the number of feet. So for every 1 second, she travels 10 feet, as indicated in the original problem.
Hope this helps.
The slope-intercept form: y = mx + b
m - the slope
b - the y-intercept
m = -2; (0; 3) → b = 3
subtitute
y = -2x + 3
You need to calculate the two zeros of the function. The first zero is the "start", the second zero is the "end" of the trajectory.
Well...
0 = x(-16x+80)
First zero is x=0 (the start of trajectory)
Second zero:
-16x+80=0.... x=5! (The end of the trajectory!)
Good luck!
