Answer: First option 108°
Each label is equivalent to an angle of:
Angle=360°/n
Number of label: n=10
Angle=360°/10
Angle=36°
To map label i to label f in a counterclockwise rotation, we must pass by 3 regions: i to h, h to g, and g to f; each one of 36°. Then the measure of a counterclockwise rotation about the spinnercenter that maps label i to label f is:
Measure=3(36°)
Measure=108°
Answer:
18:19
Step-by-step explanation:
Given that,
The radius of circle A = 9 cm
The diameter of circle B = 19 cm
We know that,
Radius = diameter/2
The radius of circle B = 19/2 cm
The circumference of circle A is :
....(1)
And that of circle B is :
....(2)
Dividing equation (1) and (2) :

Hence, the ratio of circumferences of Circle A and Circle B is 18:19.
Answer:
Step-by-step explanation:
The function is

Correct description is the first option with the exception of point (2,0), it should read (2, 0.5)
- On a coordinate plane, a piecewise function has 2 lines. The first line has an open circle at (2, 0) and then goes up through (1, 2) with an arrow instead of an endpoint. The second line has a closed circle at (2, 6) and goes up through (3, 7) with an arrow instead of an endpoint.

The slope is 0.
Using the formula (y2-y1) / (x2-x1), we wee that when subtracting y2 from y1 we get zero in the numerator and 7 in the denominator.
0/7 = 0
Another way to determine this is by plotting the two points and seeing that they form a horizontal line, indicating that there is a slope of 0.
