First, we find the distance between the two points. The equation is

d = √[(x1 - x2)² + (y1 - y2)²]
d = √[(-2 - 4)² + (-3 - 1)²]
d = 52

In a right triangle, the legs are the hypotenuse, the shorter and the longer side. The hypotenuse is the longest side, so this must be 62 units. So, she found the length of the longer side, which is 52 units.

The number of fish in the bucket before Jasper feeds the dolphins was 12.

Since Jasper won the raffle at the zoo and gets to feed the dolphins, and the dolphin trainer gives Jasper a bucket of fish to divide evenly among 4 dolphins, and each dolphin gets 3 fish, to find the number of fish F in the bucket Before Jasper feeds the dolphins, the following equation must be performed:

  • Number of dolphins = D
  • Fish for each dolphin = E
  • Total fish = F
  • D x E = F
  • 4 x 3 = F
  • 12 = F

Therefore, the number of fish in the bucket before Jasper feeds the dolphins was 12.
