Answer:
Ratio is 9
Step-by-step explanation:
Common ratio can be obtained by dividing second term by first term, third term by second term etc
Therefore
99/11 = 9
891/99 = 9
The common ratio is 9
Answer:
y=x-1
Step-by-step explanation:
those lines by the x are absolute value lines and the absolute value of x is x so the equation basically stays the same
Answer:
The interior angle measure of a convex decagon is 144.
Step-by-step explanation:
The sum of the interior angle formula for a convex polygon is (n-2)180
where n is the number of sides.
A decagon has 10 sides.
10-2 = 8
8 times 180 = 1440
A decagon has 10 sides-10 angles.
To find the measure of each angle divide by 10.
1440/10=144
The interior angle measure of a convex decagon is 144.
The sequence for the nth term is (6n+6)+1
Hence the 77th term would be
( 6(77) + 6 ) + 1
=469
