Answer:
6-2=4
31/5 x 8 = 248/40
15/8 x 5 = 75/40
248-75=173
4 13/40
answers in order
6-2=4
6 1/5 - 1 7/8 = 4 13/40
Hope this helps
Step-by-step explanation:
A=2
F(2)=2^4-2*2^3+3*2^2-10*2+3
=16-16+12-20+3=-5
a) The coordinates of A (2,9)
b) The coordinates of C (5,6) [Refer image]
How is the midpoint of AB calculated?
Point A =
= (2,9)
Point B =
= (2,3)
Midpoint of AB is

How is the point C calculated?
Given:
Point C is three squares directly to the right of midpoint of AB.
So, the point C lies at :
(2 + 3 ,6 ) = ( 5 , 6)
What is midpoint ?
- The midpoint is a line segment's centre point in geometry.
- It is the centroid of the segment and the endpoints and is equally spaced from both endpoints.
- It splits the area in half.
- The construction of a compass and straightedge can be used to calculate the midpoint of the line segment ,they determine given two points of interest.
- A lens can be built using circular arcs of equal radii centred at the two endpoints to determine the midpoint of a line segment contained in a plane and the lens' cusps are then connected.
