Answer:
The length of arc PQ is 8.1 inches.
Step-by-step explanation:
First, you have to find the angle of POQ. Given that total angles in a circle is 360°, so you have to subtract to get ∠POQ :
Next, you have to apply length of arc formula, Arc = θ/360×2×π×r where θ represents the angle of arc and r is the radius of circle :

Answer:
Approximate percent error = 15%
Step-by-Step Explanation:
Let the percentage of error be "e"
Anticipated sales = 2,500
Actual sales = 2,125
The percentage error "e" can be calculated as per the equation below:
2500*(1-e) = 2125
(1-e) = 2125/2500
1-e = 0.85
e = 1-0.85
e = 0.15
e = 15%
Approximate percentage error = 15%
Answer:10.67
Explanation:The given series is a geometric series:
8 , 2 , 0.5 , ...... etc
The general formula of the geometric sequence is:
a1 , a1*r , a1*r² , ......
Comparing the general form with the given, we would find that:
a1 = 8
a1 * r = 2
Therefore:
8*r = 2
r = 2/8 = 0.25
We can double check using another term as follows:
a1 = 8
a1*r² = 0.5
8r² = 0.5
r² = 0.5/8 = 0.0625
r = √0.0625 = 0.25
Now, we will get the sum of the sequence as follows:
S =
=
= 32/3 = 10.67
