IF the central angle is in degrees then the
arc length = (12 / 360) * circumference
arc length = (1 / 30) * 2 * PI * 30
arc length = 2 * PI inches

Answer:
0
Step-by-step explanation:
let the vertices on either side of the 0 be A and B
then let the vertex opposite of O be C
First, angle ACB will be equal to 90° as it is the angle that lies on the same arc as the diameter. From there you can find angle y with angle A+ angle B+ Angle C=180°
then you can find the angle complementary to x with the same formula then you can subtract that angle with 90° to get x.
Answer:
x= -0.785
Step-by-step explanation:
12x plus 2x equals 14x
negative 14 plus 3 equals negative 11
negative 11 divided by 14 equals x
Answer:
B. The rate of change of item I is equal to the rate of change of item II.
Step-by-step explanation:
The rate of change can be calculated using formula
where and are two points on the line.
<u>Item I:</u>
Then the rate of change is
<u>Item II:</u>
Chosse two points the line passes through. For example, (0,-3) and (1,-3).
Then the rate of change is
Hence, the rate of change of item I is equal to the rate of change of item II.
