Find the midpoint, M, of the line segment joining the points A = (-4,2) and B = (2,-3)

the correct option is 2.

step-by-step explanation:

according to the given information triangle abc is a right angle triangle with right angle at a. segment ab is 5 and segment ac is 7. point d is on segment bc and angles adb and adc are right angles.

it is given that triangles abd, cad, and cba are similar.

two triangles are similar if their corresponding sides are proportional.

in triangle cba, using pythagoras theorem

                      )

triangle abd and cba are similar,

                            (2)

triangle cad and cba are similar,

                      )

using (1), (2) and (3), we get

hence proved.

therefore option 2 is correct.

step-by-step explanation:

a fish tank full of water and then fish, regardless of the shape of it, has a certain volume.   volume is how much of something fills up the inside of a shape.   if the shape of the tank is a sphere, thr volume formula for a sphere is

we are given that the diameter of the sphere is 14, so that means that the radius is half of that at 7.   filling in to find the volume of the sphere:

do the math on that and you find that the volume of the tank is 1436.755

if there is to be 1 fish for every 693 cubic inches, we must divide the total volume of the tank by 693 to get the number of fish that will fit comfortably.

1436.755/693 = 2.07

since you can't have .07 of a fish, we round down to the nearest whole number to get that 2 fish will be able to swim comfortably in the tank.
