I think you divide 20 and 8 ... I just took a wild guess, I'm not the best at shape/figure questions, so I'm really sorry.
Hopefully that helped! :)
Answer:
<h2>x = 88.2</h2>
Step-by-step explanation:
Look at the picture.
Use tangent:
We have a measure of the angle and length of the adjacent:
Substitute:
<em>multiply both sides by 500</em>
Answer:6%
Step-by-step explanation:
Decrease = 1500 - 1410= 90
% decrease = (90/1500)*100%
= 6%
The general formula for geometric series is tn = a×rⁿ⁻¹. In this question, a (or a1) is 3, and r is 1.1, therefore the first ten terms would be 3×1.1⁰ (3) , 3×1.1¹ (3.3), 3×1.1² (3.63) and so on up until you get to 3×1.1⁹ or 7.07.
