Answer:
square root of 25=5 and square root of (x+9)=(x+9) so the answer is.... x+9=+-5
Step-by-step explanation:
G = number of green = 7
S = number of striped = 8
T = number total = 10+7+8 = 25
probability of picking green = P(G) = G/T = 7/25
probability of picking striped = P(S) = S/T = 8/25
P(green and striped) = P(G)*P(S) ... events are independent
P(green and striped) = (7/25)*(8/25)
P(green and striped) = (7*8)/(25*25)
P(green and striped) = 56/625
P(green and striped) = 0.0896
--------------------------------
In summary, the answer as a fraction is 56/625
In decimal form, the answer is 0.0896
The value 0.0896 can be converted to percent form to get 8.96%
We want to find 
such that 
. This means
Integrating both sides of the latter equation with respect to 
tells us
and differentiating with respect to 
gives
Integrating both sides with respect to gives
Then
and differentiating both sides with respect to 
gives
So the scalar potential function is
By the fundamental theorem of calculus, the work done by 
along any path depends only on the endpoints of that path. In particular, the work done over the line segment (call it 
) in part (a) is
and does the same amount of work over both of the other paths.
In part (b), I don't know what is meant by "df/dt for F"...
In part (c), you're asked to find the work over the 2 parts (call them 
and 
) of the given path. Using the fundamental theorem makes this trivial:
