The arc length is the measure of the distance along the curved line making up the arc<span>. It is longer than the straight line distance between its endpoints. To calculate this we simply multiply the angle to the circumference of the circle. It is expressed as:
Arc length = 2</span>πr(angle / 360)
Arc length = 2πr(50 / 360)
Arc length = 5πr / 18
Just multiply the radius then you're good. Hope this helps. Have a nice day.
Answer: 
Multiply both sides by -6 to undo the operation of "division of -6" that is happening to x. This will isolate x and lead to the answer. Keep in mind that multiplying both sides by a negative number will flip the inequality sign.
Answer:
option (b) df = 1, 24
Step-by-step explanation:
Data provided in the question:
levels of factor A, a = 2
levels of factor B, b = 3
Subjects in each Sample, s = 5
n = 5 × 3 × 2 = 30
Now
df for Factor A = a - 1
= 2 - 1
= 1
df for Factor B = b - 1
= 3 - 1
= 2
df for Interaction AB = ( a - 1 ) × ( b - 1 )
= 1 × 2
= 2
df for Total = n - 1
= 30 - 1
= 29
df for error = 29 - 5
= 24
Hence,
df values for the F-ratio evaluating the main effect of factor A is 1, 24
The correct answer is option (b) df = 1, 24
The first one
1 because if your see it on the scale it shows -2 and 2 then add that up there you go
Answer:
Yes, both shapes appear to be congruent.
Step-by-step explanation:
Both shapes are congruent.
<u>Reasoning:</u>
1) Both shapes are ovals.
2) Both shapes are of the same size.
3) Both shapes are just in a different position.
4) Shape 1 is rotated 90 degrees left or right to form shape 2.
