Answer:
100 degrees
Step-by-step explanation:
Angle on a straight line = 180
angle 5 = 180 = 80 = 100 degrees
Answer:
The correct answer is option A. 90°
Step-by-step explanation:
<u>Points to remember</u>
Measure of angles on the semicircle is 90°
From the figure we can see a semicircle and a triangle inscribes on it.
<u>To find the measure of <XYZ</u>
Here <XYZ is on the semicircle that is angle XYZ is a right angle.
Therefore m<XYZ = 90°
The correct answer is option A. 90°
Answer:
-5/2
Step-by-step explanation:
Slope m = (y2-y1)/(x2-x1)
m = (-2 - 8)/(6 - 2) = -10/4 = -5/2
so y = mx + b
y = -5/2x + b
Using (2,8)
8 = -5/2(2) + b
8 = -5 + b
b = 13
then y = -5/2x + 13
Answer:
B. 3/4
Step-by-step explanation:
Care with these types of graphs as the values are 2 rather than one on each axis.
Away from that, rate of change can also be named "slope" in which how many units up or down the y-value goes per x value. To find the slope or "rate of change" you want to use 
.
To find the rise over run you want to go up from any point where the x and y value line up to another. The origin or (0,0) can be used to do this. Look at point (8,6) to see this. Rise from the origin 6 times and run to the right 8 times. Rise OVER run so the rate of change can be shown as 6/8 which can be simplified to 3/4.
The graph is touching the x-axis at x= 2 and is turning away.
When a graph exhibit such a behavior at a root, we say that the multiplicity of the root is 2. So the roots of the polynomial are x = 2 and x = 2. The factors of the polynomial are (x - 2) and (x - 2)
The polynomial thus can be written as product of its factors as (x-2)(x-2)
So the correct answer to this question is option B
