<h3>
Answer: Choice B) -471,861</h3>
=====================================================
Explanation:
This is a geometric sequence because each new term is found by multiplying the last term by -4.
The common ratio is r = -4. The first term is a = -9. We want to sum up n = 9 terms.
Use the geometric nth partial sum formula below to plug in the terms mentioned

Should be 37 degrees
We know the lengths of the adjacent and opposite sides when looking at the angle x, so we use those two sides to find the trig ratio.
So we use Opposite/adjacent (Tangent) Which is 54/72=0.75
Now we get out the trig ratio table. Because we used the tangent ratio (O/A) , we use that column to look for the closest number to 0.75.
The closest is 0.754, and the degree for it is 37 degrees
Rlly hope this helps :)))
Answer:
10x2 + 2x + 13.
Step-by-step explanation:
10x2 + 3 - (-2x - 10) (Note you have to put the -2x - 10 in brackets).
= 10x2 + 3 + 2x + 10 (Distributing the negative over the brackets).
= 10x2 + 2x + 13.
