Answer:
D(4,-3)
Step-by-step explanation:
Given three of the vertices of the square: A(4, -7), B(8, -7),C(8, -3)
Let the coordinate of the fourth vertex be D(x,y).
We know that diagonals of a square are perpendicular bisector. So, the midpoint of both diagonals is the same.
The diagonals are BD and AC
Midpoint of BD = Midpoint of AC

The coordinates of the fourth vertex is D(4,-3)
X^1/2 - x
-2x^3 - x^1/2 - x
-2x^3 - 2x
i think this is it
Answer: C
Step-by-step explanation: As they are interested in the amount of time a client exercises in a week, the population would be all the clients that use the fitness center for a given week.
Clients that do not go on this week are not part of the population. The amount of time is what they want to know, so it cannot be the population.
