Im not 100% about how this question is explained or written but i think its 8
Answer:
The slope of the line is the ratio of the rise to the run, or rise divided by the run.
Step-by-step explanation:
HOPES THIS HELP :)
I believe it is -81k^2
-27k^3-81k^2-81k-27
x = 6.03 seconds
Step-by-step explanation:
The equation of motion of the rocket is
y = -16x^2 + 193x + 128
We can determine its maximum height ymax when its vertical velocity y' reaches zero. Taking the derivative of y, we get
y' = -32x + 193
The value nen of x that makes y' will give us the time needed by the rocket to reach its maximum height ymax. So setting y' = 0 we get
x = 193/32 = 6.03 second
Bonus:
Putting this value of x into y, we'll get
y(x = 0.59s) = -(16 ft/s^2)(6.03 s)^2 + (193 m/s)(6.03 s) + 128 ft
= 710 ft
I think the answer's B! Please don't quote me on this, but I'm almost positive! (:
i hope all is well, and you pass!
