There are different types of parallelograms,and you probably have the notes determining what type it is. So like it could be a square, rectangle, rhombus..
I’m not sure what you’re looking for but I got 11x - 1 = 11 x - 1 and the statement is true
Answer:
The solutions of the equation are -41.8° , 0.0° , 41.8°
Step-by-step explanation:
∵ 3 sin²Ф - 2 sinФ = 0 is a quadratic function
∵ The domain of the function is -90° ≤ Ф ≤ 90°
- Lets take sinФ as a common factor
∴ sinФ (3 sinФ - 2) = 0
- Two terms multiplied by each other = 0
∴ One of them must be equal zero
∴ sinФ = 0 or 3 sinФ - 2 = 0
- If sinФ = 0 ⇒ Ф = 0.0°
- If 3 sinФ - 2 = 0 ⇒ 3 sinФ = 2 ⇒ sin Ф = 2/3
∵ sinФ 2/3
∴ Ф = 41.8° ⇒ Ф ≤ 90° (in first quadrant)
∵ -90° ≤ Ф ≤ 90°
∴ Ф = -41.8° ⇒ Ф ≥ -90° (in fourth quadrant)
∴ The solutions of the equation are -41.8° , 0.0° , 41.8°
I hope this helps I got it from my math book, Rational numbers are used everyday. Write three instances in which you use each representation of a rational number--fractions, decimals,and percentages-- in your daily activities. Does a certain representation appear to be used most often?
Hope this helps & if you don’t understand something just ask :)
