Here we go ~
1. A circle can be named by their Centre, so here in the diagram it's :
- Circle A
2. Name 4 radii :
Radii are the line segments that joins the centre and boundary of circle.
They are :
- FA
- GA
- BA
- CA
3. 2 Major arcs :
considering two points on a circle, and joining them forms a curve ( you can say part of circumference )
When we consider two points two arcs are formed and the arc with more length is known as Major Arc
That is :
- Major arc ECF
- Major arc BEC
4. A Semicircle :
Semicircle is special arc which is formed when two arcs formed by the points are equals to one another... it's also half the Perimeter of circle.
that is :
- Arc CF is a Semicircle
5. 3 minor arcs :
The arc formed by two points having lesser length is known as minor arc.
that is :
- Arc EF
- Arc BG
- Arc FG
6. 3 Central angles :
Central angles are angles formed by arcs on centre of the circle ~
that is :
- Angle FAB
- Angle BAC
- Angle GAB
7. A diameter :
Diameter is a chord that passes through centre of the circle.
- CF
8. Congruent Angles :
In the given figure, there are two equal/congruent angles that are ~
- Angle BAG and Angle GAF
9. Adjacent arcs :
The arcs that have one common end point are known as Adjacent arcs ~
that are :
- Arc FG and Arc GB
<u>Answer:</u>
The correct answer option is D.
<u>Step-by-step-explanation:</u>
We are given the following two functions:
and
We are to find so we will subtract the function g from function f, arrange the like terms together and combine them like shown below to get:
Therefore, is equal to
so the correct answer option is D.
.
Answer:
no solution
Step-by-step explanation:
Given the 2 equations
y = x + 4 → (1)
- x + y = - 5 → (2)
Substitute y = x + 4 into (2)
- x +
x + 4 = - 5 , that is
4 = - 5 ← not possible
This indicates the system has no solution
