Answer:
150°
Step-by-step explanation:
It is given that CosФ < 0 i.e CosФ is negative.
Therefore, the minimum the value of Ф for which CosФ <0 will be in the second quadrant i.e 90° < Ф < 180°.
Now it is also given that, Sin Ф =0.5 {the value of SinФ is positive because Sin value is positive in second quadrant.}
⇒ Ф =180° - Sin⁻¹ (0.5) = 180°-30° =150° (Answer)
Answer:
The elevation is a nonlinear function.
Step-by-step explanation:
Im gonna assume you are solving for x, the equation (x + 3)2 = 49 x is equal to 21.5 or 21 and 1/2. however the rest aren’t equations they’re just x = number and there isn’t much to do with that
Answer:
She can chose 2 books from 8 books in 28 different way.
Step-by-step explanation:
In the given scenario the member has to chose 2 books from a group of 8 books. The order of choosing books does not matter. For example if the books are A,B,C,D,E,F,G and H, and the member picks books A and B or books B and A, she is picking up the same books. This means order of selection does not matter here, so this is a problem of combinations.
We have to form combination of 8 books taken 2 at a time i.e. 8C2
The general formula of combination is:
Using the values of n=8 and r=2, we get:
This means, she can chose 2 books from 8 books in 28 different ways.
