Answer:
The width which gives the greatest area is 7.5 yd
Step-by-step explanation:
This is an application of differential calculus. Given the area as a function of the width, we simply need to differentiate the function with respect to x and equate to zero which yields; 15-2x=0 since the slope of the graph is zero at the turning points. Solving for x yields, x=7.5 which indeed maximizes the area of the pen
Answer: None of the above
Step-by-step explanation:
Given


Now, integrating both sides



Answer:
0.36
Step-by-step explanation:
0.6 squared is 0.36
it is essentially 6 times 6 but as a decimal
A) 0 represents the surface of the pool.
B) The height of the pool is 10 above the pool surface
C) It should be -3 since it is going down so it is going to be a negative number and it is also below the pool's surface.
19=1-5h-4h
19-1=-5h-4h
18=-9h
18/-9=h
h=-0.5
