Answer:
Option B and C are correct.
are the expression incorrect for slope
Step-by-step explanation:
Slope is defined as the change in the dependent variable relative to the change in the dependent variable
or the ratio of the horizontal changes to vertical changes between any two points on the graph of the line.
The vertical changes between any two points is rise
The horizontal changes between any two points is run.
Formula for slope is given by:
For any two points 
and 
then slope is:
or we can write this as:
Δy = 
Δx = 
⇒
Therefore, the expression which are incorrect for slope are;
Answer:
Step-by-step explanation:
13500/3 = 4500
4500 x 2 = 9000
62% because 200 silver coins out of 323 (total of all coins) is .619..., resulting in 62%
Answer:
(x^2-6)(x+2)(x-2)
Step-by-step explanation:
x^4-10x^2+24
(x^2-6)(x+2)(x-2)
I will use this notation m arc AB to name the measure of the arc AC in degress, going from A to B counterclock wise.
Also, note that the measure of an arc is equal to the measure of the central angle from which the arc is generated.
With that:
1) m arc AB
m arc AB is equal to the angle AOC
The angle AOC is indicated to be 49°, so m arc AB is also 49°.
Answser: 49°
2) m arc ABC
m arc ABC is equal to 360° - angle COA = 360° - 107° = 253°
3) m arc BAC
m arc BAC is equal to angle AOB + angle COA
m arc BAC = 49° + 107° = 156°
Answer: 156°
4) m arc ACB
m arc ACB = 360 ° - angle AOB = 360° - 49° = 311°
Answer: 311°
