Answer:
t = 0, t = - 2
Step-by-step explanation:
Given
- t² - 2t = 0 ← factor out t from each term
t(- t - 2) = 0 ← in standard form
Equate each factor to zero and solve for t
t = 0
- t - 2 = 0 ( add 2 to both sides )
- t = 2 ( multiply both sides by - 1 )
t = - 2, thus
solutions are t= 0, t = - 2
Answer:
Step-by-step explanation:
If you graph there would be two different regions. The first one would be

And the second one would be
.
If you rotate the first region around the "y" axis you get that

And if you rotate the second region around the "y" axis you get that

And the sum would be 2.51+4.188 = 6.698
If you revolve just the outer curve you get
If you rotate the first region around the x axis you get that

And if you rotate the second region around the x axis you get that

And the sum would be 1.5708+1.0472 = 2.618
Answer:

Answer:14127
Step-by-step explanation:
Po=2100
T=11
D=4
Pt=po•2 t/d
Pt=2100•2 11/4
Pt=14127.0598=14127
