Step-by-step explanation:
Answer:
B) 36 ft
Step-by-step explanation:
Given:
The height as a function of time is given as:
At maximum height, the instantaneous velocity becomes 0. The instantaneous velocity is the first derivative of the height function.
So, the derivative of the the given function is 0 at the maximum height.
Differentiating the above function with time, we get
Now, equating the derivative to 0 and finding time.
Therefore, time taken to reach maximum height is 1.5 s.
Now, maximum height is obtained by plugging in 
in the height equation.
Maximum height is given as:
Against the wind 100 m 15 sec = 6.67 mtrs / sec
With the wind 100 m 10 sec = 10 mtrs / sec
psa means plane velocity in still air
ws means wind speed
psa -ws = 6.67
psa + ws = 10
Adding both equations we get:
2 * psa = 16.67
psa = 8.34 meters per second
Since psa + ws = 10 and psa = 8.34 then wind speed = 1.66 meters per second

➷ Multiply 4.6 by 4 to get the sum of the numbers after 5 was added:
4.6 x 4 = 18.4
^ This is the new total
Subtract 5 from this:
18.4 - 5 = 13.4
Divide this value by 3 to get the original mean:
13.4/3 = 67/15

Answer: Choice D</h3>
Explanation:
For now, let's ignore the blue curve.
If we kept the red curve completely fixed in place, and only moved the xy axis, then we can move the xy axis 5 units to the right to give the illusion the red curve is moving (even though it's fixed in place).
Moving the xy axis 5 units to the right means each x input is 5 units larger. So x jumps up to x+5
In other words, going from f(x) to f(x+5) will shift the f(x) curve 5 units to the left. So that's why we go from x^2 to (x+5)^2 which is what choice D shows.
