Answer:
Step-by-step explanation:
Remark
Assume all of the sheet of plywood is to be used.
Front and back = 2 * 2x *h
Top and Bottom = 2 * 2x * x
Left/Right side = 2 * x * h
Total area = 4xh + 4x^2 + 2xh
Total area = 6xh + 4x^2
Total area = 600
6xh + 4x^2 = 600
h = (600 - 4x^2)/6x
h = 100/x - 2/3 x
Volume = x * 2x * h
Volume = 2x^2 * (100/x - 2/3 x)
Volume = 200x - 4/3 x^3
I can do this without calculus (I think), but it is much easier to use it.
dV/dx = 200 - 4x^2
This is a maximum when dV/dx = 0
dV/dx = 200 - 4x^2 = 0
4x^2 = 200
x^2 = 50
x = 5√2
Part A: No, he is not correct because when both rounded to the nearest hundredth they equal the same weight. Jayden's fish is 2.12 rounded to the nearest tenth and Leah's fish weighed 2.12.
Part B: 2.12 = 2.120
I hope this helps you!
Answer:
0 is the answer
Step-by-step explanation:
4-4=0
7-7=0
For acceleration use this formula: (v-u) /t
V is the final velocity
U is the intial velocity and t is time.
For speed u hav to calculate the the total distance and total time then use this formula:
Average speed=
Total distance / Total time
