No if you divide by 2 anything will work
Answer:
1152 ways
Step-by-step explanation:
There are 4 married coupes i.e. four women and four men.
Let us treat four women as one unit together and 4 men as one unit together.
We have 2 units which can be arrangedi in 2!= 2 ways
Among 4 women they can arrnage themselves in 4! = 24 ways
Similarly 4 men can sit in 4! ways together
Hence total number of ways
they can arrange themselves if all the women sit together and all the men sit together
= No of ways 2 units arranged * no of ways men arranged * no of ways women arranged
=2*24*24
= 1152
Answer:
D. 80 mph
Step-by-step explanation:
d- distance
- d/50= 0.6d/40+0.4d/x
- 1/50= 0.3/20+0.4/x
- 0.4/x= 0.02- 0.015
- x= 0.4/0.005
- x= 80 mph
Differentiate using the chain rule:
d/du [ln(u)] d/dx[2x^3+3x]
derivative of ln(u) = 1/u
1/u d/dx[2x^3+3x]
1/2x^3+3x d/dx[2x^3+3x]
Differentiate
(6x^2+3) 1/2x^3+3x
Simplify
Dy/dx = 3(2x^2+1) / x(2x^2 +3)
