6=5/2(6)+b
6=15+b
subtract 15 from both sides
b=-9
You would take 10 and divide that by 16 to get .63, so you take .63 and minus that from 100 and you get 37. so the officer had a 37% decrease.

Answer:
Area of sector = 21.75 units.
Step-by-step explanation:
Given, BAC is a sector of radius 8.
⇒ AB = 8; AC = 8.
Now, let a line from A passing through O meets the curve BC at P.
⇒AP = 8. (radius of sector).
Given, radius of inscribed circle is 2.
⇒AO = AP- OP = 8-2 = 6.
let the inscribed circle meets AB at Q. so, triangle AQO forms right angle triangle(since, AB is a tangent).
⇒ cos(∠AOQ) = 2/6 (adjacent / hypotenuse)
⇒ ∠AOQ = 70.53° ⇒ ∠OAQ = 180 - 90- 70.53 = 19.47°
⇒ total ∠A = 2× 19.47° = 38.94°.
⇒ area of sector = π×r²×, where r = 8
⇒ area of sector = 21.75 units.

================================================
Explanation:
Choice A is true assuming we have
In this case, and
--------
Choice B is false. See choice A above.
--------
Choice C is true. The sequence is decreasing. As n gets larger, gets smaller. This is because the denominator is growing larger with the numerator held constant.
--------
Choice D is false. This contradicts choice C.
--------
Choice E is true since the denominator is growing forever
This is similar to
--------
Choice F is true due to choices C and E being true.
--------
Choice G is false because it contradicts choice F.
