Answer:
Therefore the required equation is
Y=5+3X
Step-by-step explanation:
Given that , Joey has 5 collector stamps.
He gets 3 more stamps each week.
The number of week is X.
1st week he got 3 stamps
2nd week he got (3+3)=2.3 stamps
3rd week he got (3+3+3)=3.3 stamps
Stamp that he got=( the number of week ×3)
Therefore at end of Xth week he got =(X × 3) =3X stamps
Total number of stamps that collected after x week
=5+3X
Therefore the required equation is
Y=5+3X
Answer:
A positive 11
Step-by-step explanation:
11 is your answer
12 multiplied by 12 equals 144.
A "derivative" is a rate of change.
The derivative of a plain old number is zero, since numbers never change.
Pi is a number. Its value never changes. Its derivative is zero.

Answer:
38.2°
Step-by-step explanation:
The law of sines tells you ...
sin(x)/15 = sin(27°)/11
sin(x) = (15/11)sin(27°) . . . . . multiply by 15
x = arcsin((15/11)sin(27°)) ≈ arcsin(0.619078) ≈ 38.2488°
x ≈ 38.2°

<em>Additional comment</em>
In "law of sines" problems, you need to identify a side and opposite angle that you know both values of. Then, you need to identify whether you're looking for an angle or a side, and whether its opposite side or angle is known. If two angles are known, you can always figure the third from the sum of angles in a triangle.
Here, we have angle 27° opposite side 11. We are looking for an angle, and we know its opposite side. This lets us use the ratio formula directly. Since the angle is the unknown, it is useful to write the equation with sines on top and sides on the bottom.
The given angle is opposite the shorter of the given sides, so this triangle has two solutions. We assume that we want the solution that is an acute angle (141.8° is the other solution). That assumption is based on the drawing. Usually, you're cautioned not to take the drawings at face value.
