Answer:
5.3 s
Step-by-step explanation:
a) since the height is defined by a function, we can find the turning point of the quadratic , which is where the ball will have the highest point. The turning point is where the gradient is equal to zero so we differentiate first
Answer:
4.8 pounds!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Answer:
3 7 8 2 6 4 1 10 3 5 9 the answer
So basically the height is divided by a certain number to evenly divide it
Exact Surface Area = 378pi
Approximate Surface Area = 1186.92
The approximate surface area uses pi = 3.14
The units are cm^2 or "square cm".
=========================================================
Work Shown:
SA = surface area of cylinder
SA = 2*pi*r^2 + 2*pi*r*h
SA = 2*pi*7^2 + 2*pi*7*20
SA = 2*pi*49 + 2*pi*140
SA = 2*49*pi + 2*140*pi
SA = 98pi + 280pi
SA = 378pi ..... exact surface area
SA = 378*3.14
SA = 1186.92 ..... approximate surface area

Side note: The diameter 14 cuts in half to get the radius r = 7
