Part A: Plot the points A(-8,7) and B(6,-9). Mark the halfway point on AB and label it point M. What are the coordinates of M? Part B: Plot point C(2,7). If M is the midpoint of CD, what are the coordinates of D? please help me

a.

b.

Step-by-step explanation:

Given

A(-8,7) and B(6,-9).

Solving (a):

Determine the Midpoint M;

This is calculated as follows;

Where

Substitute these values in the formula

Hence; the midpoint is (-1,-1)

Solving (a):

Here, we have

C = (2,7)

M; Midpoint = (-1,-1)

Required: Determine D

This is calculated as follows;

Where

Substitute these values in the formula

Solving for x2

Multiply both sides by 2

Subtract 2 from both sides

Solving for y2

Multiply both sides by 2

Subtract 7 from both sides

Hence, the coordinates of D is

80π/3 or about 83.775

step-by-step explanation:

since a cone is 1/3 of a cylinder, we need to find the base's area. since area = πr^2, we get 16π. then, multiplying this by 5, we get 80π. dividing by 3, since the cone's volume is 1/3 of that of a cylinder's, we get 80π/3.

hope this !

step-by-step explanation:

you can add the two numbers and divide the result by 2. or you can find the gap between the two numbers and add half of this to the smaller number.
