Answer:
(-1.85, -0.15)
Step-by-step explanation:

Here,
x1 = -5.1
x2 = 1.4
y1 = -2
y2 = 1.7
Now substituting the values we have in the equation, we get:-


The coordinates of the midpoint would be = (-1.85, -0.15)
Answer:

Step-by-step explanation:
Given
See attachment for her sketch
Required
Which equation do not represent the perimeter
From the attached sketch:
--- Length
--- Width
Perimeter (P) is calculated as:

This gives:
---- This represents (A)
Open bracket
---- This represents (B)
In algebra:
means 
So, the expression becomes
--- This represents (D)
<em>This implies that (C) does not represent the perimeter</em>
The formula to find the volume of the composite solid is: C. V = πr²h + ⅔πr³.
<h3>How to Find the Volume of a Composite Solid?</h3>
The volume of the composite solid in the image given = Volume of cylinder + volume of hemisphere.
Volume of cylinder = πr²h
Volume of hemisphere = ⅔πr³
Therefore, formula to find the volume is: C. V = πr²h + ⅔πr³.
