Answer:
From what I understand the answer is B
Step-by-step explanation:
calculate the difference between the averages that we're dated from each month them look between your answers and from there calculate till you can an answer that fits for each one. The correct one being B
x is the average yearly temperature so another way to work this out as add all of the averages up and then work through by diving each average by twelve them look at the difference between the two
The area of a circle is A= pi*r^2
So we get
Area= 3.14* 4^2= 50.24ft^2
Number 4 and 6 are correct because you can only add variables with other variables so that is why 4 and 6 are correct
Answer:
(3x + 4)° + 50° = 90° (complement angle)
3x° + 4°+ 50° = 90°
3x° +54° = 90°
3x° = 90°- 54°
x° = 36°/3
x° = 12°

Sin(A+B) = SinACosB + CosASinB
Cos(A+B) = CosACosB - SinASinB
Note pi is taken as pi radians = 180 degrees. Cospi = Cos180 = -1.
Sinpi = Sin 180 = 0
Cos(A+pi) = CosACospi - SinASinpi = (CosA) * (-1) - (SinA) *(0) = -CosA.
Sin(A+pi) = SinACospi + CosASinpi = (SinA)* (-1) + (CosA) * (0) = -SinA.
Cos(A+pi) - Sin(A+pi) = -CosA - -SinA = -CosA + SinA = SinA - CosA.
Answer = (a).
