My answer was deleted but ill post it again. it is a line plotted at the point (-2,-0.5) and the slope is down 1, right twice. this is a negative line.
Answer:
Step-by-step explanation:
Always , sum of exterior angle of any polygon = 360
sum of exterior angle of 11- sided polygon = 360
Measurement of an exterior angle of 11-sided polygon = 360/11
= 32.73
Measurement of an interior angle of 11-sided polygon = 180 - 32 8/11
= 180 - 32.73= 147.27
Answer:
= 2n - 3
Step-by-step explanation:
Note the difference in consecutive terms is constant, that is
1 - (- 1) = 3 - 1 = 5 - 3 = 7 - 5 = 2
This indicates that the terms are an arithmetic sequence with
= a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = - 1 and d = 2, thus
= - 1 + 2(n - 1) = - 1 + 2n - 2 = 2n - 3
Answer:
The height is 11/2
Step-by-step explanation:
We know SA = 30n
and r = 2
We are solving for h. So plug in our values
30n = 2n(2)^2 + 2n(2)h
Multiply and square on the right side terms
30n = 8n + 4nh
Divide everything by n
30 = 8 + 4h
Subtract 8 on both sides
22 = 4h
Divide by 4 on both sides
h = 22/4 = 11/2
Check:
30n = 2n(2)^2 + 2n(2)(11/2)
30n = 8n + 22n
30n = 30n
