The area of the park will be 375 ft squared (rectangular shaped park that is)
To find avg downstream is 39/3 = 13 mph
upstream is 20/4 = 5mph
the average of the 2 is the still water speed which is 8 mph
For dA in a circle, the r value varies , but its area is still rdrd(theta) but r (and theta) differs depending where the region is
and the regions could be any regions as long as it is a continuous region
hope this helps

Good evening ,
_______________
a) p(rat)=1-(0,35+0,4+0,1)
b) p(cat ∪ hamster)=0,35+0,1
c) p(dog then dog)= (0,4)²

Answer:
Step-by-step explanation:
The Perimeter, P (feet) = 2 x Width(ft) + 2 x Length(ft)
P = 2*(3x-5) + 2*(2x+8)
P = 6x -10 + 4x + 16
P = 10x + 6 (in feet)
Total cost = P(ft)*(Cost ($/ft)) [The Cost is $5/ft]
Total cost = ((10x + 6)ft)*(5 ($/ft)) = <u>$(50x + 30)</u>
Since no value is given for x, this is the closest we can get to an answer.
[I notice that x must be greater than (1 2/3), otherwise, (3x-5) would be negative. Perhaps a negative distance is valid for the Klingons, but let's assume this is on Earth.]
