Should be B.
as x represents the week number you simply plug in 8 for X so,
y=-1.2(8)+23.5
y=13.9 that is just 14 then
<span>I think the answer would be:
B) y= 4 cos 2 theta</span>
Volume of the cylinder

r = 4
h = 9
Volume

</h2><h3>Option A is the correct answer </h3>
Hope this will help....
Answer:
x = 142
Step-by-step explanation:
√x+2 - 15 = -3 (Given)
√x+2 = 12 (Add 15 on both sides)
x + 2 = 144 (Square both sides to get rid of the radical)
x = 142 (Subtract 2 on both sides)
20. (a) a rectangle
(b) a circle
(c) triangle
22. volume = pi r^2 h
10 = pi r^2 * 2
r^2 = 10 / 2pi = 1,5915
r = 1.262
diameter = 2 *1.262 = 2.52 feet to the nearest hundredth Answer
