Answer:
156
Step-by-step explanation:
s8 = n/2 [2t + (n-1)(d)]
= 8/2 [2(2) + (8-1)(5)]
= 4 [4 + (7)(5)]
= 4 (4 + 35)
= 4 (39)
= 156
18/24 = 3/4 (divide top and bottom by 6)
answer is <span>A. 3:4</span>
Answer:
a=-1
Step-by-step explanation:
1/2a=1/4a+2
by cross multiplying,
2a=4a+2
2a-4a=2
-2a=2
a=2/-2
a=-1
hope you understood :)
We're looking for
such that
, which requires



Integrating both sides of the first PDE wrt
gives

Differenting this wrt
gives


but we're assuming
is a function that doesn't depend on
, which is contradicted by this result, and so there is no such
and
is not conservative.
