The slope is 2 I’m pretty sure
Find surface area
SA=2pir^2+2hpir
h=42
r=1.5
SA=2pi1.5^2+2(42)pi1.5
SA=4.5pi+126pi
SA=130.5pi square inches
area/areacoverdperspray≤numberofsprays
130.5pi/150
2.73
so buy 3 cans because you can't get 0.73 cans
A
The beginning of the line segment starts at 5, and ends at 9.
Therefore,
5 - 9 = 4
The length of the segment is 4.
Answer:
Step-by-step explanation:
Initial class size = 30 students
<u>Class size now is 40% larger:</u>
- 30 + 40% =
- 30 + 30*40/100 =
- 30 + 12 =
- 42
follows from the fact that the cosine function is
-periodic, which means
. Roughly speaking, this is the same as saying that a point on a circle is the same as the point you get by completing a full revolution around the circle (i.e. add
to the original point's angle with respect to the horizontal axis).
If you make another complete revolution (so we're effectively adding
) we get the same result:
. This is true for any number of complete revolutions, so that this pattern holds for any even multiple of
added to the argument. Therefore
for any integer
.
Next, because
, it follows that
is also true for any integer
. So we have
The rest follows from considering either case and solving for
.
