Answer:
Step-by-step explanation:
To find the reference angle of a given angle, first of all, the quadrant of the given angle is determined.
So for 7pi/12
The quadrant is 2nd.
For the angle belonging to 2nd quadrant the equation for reference angle will be:
r=180 - theeta
The answer is B.
1. Use the quadratic formula
2. Solve everything under the square root
3. Solve the denominator

Answer:
150 million square kilometres
Step-by-step explanation:
hope this is right
15 mil x 10 = 150 mil
10% x 10 = 100%
Answer:
b Superscript positive
Step-by-step explanation:
Negative exponents in the denominators can be evaluated by moving the function from the denominator to the numerator and changing the power from negative to the positive.
We have
1/b⁻² = b²
Moving the function with a power from denominator to numerator or from numerator to denominator changes the sign of the power. It is not equal to zero.
This is the property of exponents.
