Answer:

Step-by-step explanation:
Given:

To solve:
The given equation.
Solution:
First of all, let us consider an important property of sine and cosine.

OR

We can apply above property to solve for
as per given equation.

Changing
to sine form:



So, solution to the equation
is:

Answer:
the third one
Step-by-step explanation:
the square root of 25 is 5. 5+2 = 7.
this is a rational number (the set of all integers and fractions).
the other 2 portions contain at least one element that is not rational. and so the sum with such a number is not rational.
45 and 7 are no square numbers, and therefore the square root of these numbers contains a neverending chain of digits after the decimal point without having any repeating pattern. these are real numbers but not rational numbers.
Answer:
Step-by-step explanation:
I assume we are finding the slope of the line. It is positive since it runs from the lower left to the upper right, so forget B and D. Since slope is defined as rise over run, in order to get from one point on the line that goes through right where the grids meet to another point that goes through right where the grids meet we count up 1 unit and then to the right 6 units. This is a slope of 1/6.
Answer:
3x+12
Step-by-step explanation:
-0.5x*2+4x+12
Multiply 0.5x*2=x
= -x+4x+12
Add similar elements -x+4x+12
= 3x+12
The answer to your question is 12b^2
Because 3-12 is -9 pal :)
