Answer:
17.03 units
Step-by-step explanation:
The distance formula for the distance between two points (x1, y1) and (x2, y2) is ...
d = √((x2 -x1)^2 +(y2 -y1)^2)
For the given points, the distance is ...
d = √((8-(-3))^2 +(-6-7)^2) = √(11^2 +(-13)^2)
d = √(121 +169) = √290
d ≈ 17.03
The distance between the points is about 17.03 units.
well, we know the shaded region has an area of 5x²+3x-4, there are three more sections of equal shape, so their areas must also be equal, meaning there are four regions of the same area of 5x²+3x-4, thus 4(5x²+3x-4) = 20x²+12x-16.
It would take them 1 hour and 30 min to get across, and 2 hours to cross back. In total it would take them 3 hours and 30 min to complete the trip.
