let's recall that d = rt, or namely distance = rate * time.
b = speed of the boat
c = speed of the current
now, we know that going downstream the boat went 16 miles total, that's going only one way, so the distance the boat travels downstream as well as upstream to return is 16 miles flat.
when going downstream, the boat is not really going at "b" speed, is really going at "b + c" speed, because the current is adding its speed to it, so is really going faster than "b".
when going upstream, the boat is not really going at "b" speed" either, is really going slower at "b - c" speed, because the current is against it and thus subtracting speed from "b".
let's take a look at those in a table
1. multiply 1 and 3 to equal 3 then subtract 4 to equal -1
Answer: 274.75
Step-by-step explanation:
To find the volume of a cylinder you find the area of the base and then multiply it by the height. The base is the radius (half the diameter) squared times pi which we will use 3.14. That gets us 78.5. Then we multiply by the height to get 274.75!
Hope this helps!
Slope=change in y/change in x
so
from (-4-2) to (-2,-10)
change in y is from -2 to -10, that is -8 change
change in x is from -4 to -2 which is 2 change
-8/2=-4
slope is -4
B
realk way
for
(x1,y1) and (x2,y2)
slope is (y2-y1)/(x2-x1)
so
(-4,-2) and (-2,-10)
slope=(-10-(-2))/(-2-(-4))=(-10+2)/(-2+4)=-8/2=-4
B is answer
