Answer:
5.25 seconds
Step-by-step explanation:
The vertex of the parabola defined by ax²+bx+c is located at x = -b/(2a).
The time to maximum altitude is ...
x = -(168)/(2(-16)) = 168/32 = 5.25
The time at which maximum height is reached is 5.25 seconds after launch.
Answer:
No Solution
Step-by-step explanation:
| −2n | + 10 = −50
Subtract 10 on both sides
|-2n|+10-10=-50-10
Simplify
|-2n=|=-60

Answer:
The plot is attached.
Step-by-step explanation:
Plot the function y(x)=e^–0.5x sin(2x) for 100 values of x between 0 and 10. Use a 2- point-wide solid blue line for this function.
The step value for x is (10-0)/100=0.1.
Plot the function y(x)=e–0.5x cos(2x) on the same axes. Use a 3-point-wide dashed red line for this function.
The step value for x is the same as the previous function.

W= 34, thats what the answer is.
