Answer:
27 ft
the maximum height of the arrow is 27 ft
Step-by-step explanation:
Given;
The height of the arrow is given by the function;
h(t) = -16t^2 + 32t + 11
Maximum height is at point when dh(t)/dt = 0.
Differentiating h(t), we have;
dh/dt = -32t + 32 = 0
Solving for t;
-32t = -32
t = -32/-32 = 1
t = 1 (time at maximum height is t = 1)
Substituting t=1 into h(t), to determine the value of maximum height;
h(max)= -16(1^2) + 32(1) + 11
h(max) = 27 ft
the maximum height of the arrow is 27 ft.
Answer:

Step-by-step explanation:


Answer:
2 + x + y
Step-by-step explanation:
3x+6y-1=0
All the letters and all the numbers should be on seperate sides so...
The -1 is added onto the zero like this:
3x+6y=0+1
3x+6y=1
Answer: The sample mean and sample standard deviation is 74.004 millimeters and 0.005 millimeters respectively.
Step-by-step explanation:
The given values : 74.001, 74.003, 74.015, 74.000, 74.005, 74.002, 74.007, and 74.000.

The sample standard deviation is given by :-

Hence, the sample mean and sample standard deviation is 74.004 millimeters and 0.005 millimeters respectively.
