Answer:
It comes from correct solution steps and is not a valid solution of the equation.
Step-by-step explanation:
When we use arcsine, we are finding the angle while giving the trigonometric ratio.
Arcsin(u) = theta can be rewritten as:
sin(theta) = u
Sine is opposite over hypotenuse, so u/1 means that the side opposite to theta (the y value) is u, and the hypotenuse is 1.
We can use Pythagorean Theorem to find the adjacent (x value).
1^2 - u^2 = x^2
x = sqrt(1-u^2)
Back to the original question, we are trying to find cos(arcsin(u)). We just solved all the sides for our triangle using arcsin(u). Now we need to do cos(u).
Cosine is adjacent over hypotenuse.
So our answer is sqrt(1-u^2)/1
Or just sqrt(1-u^2)
Answer: 10 I believe
Step-by-step explanation:
The correct answer is -2
Can you mark me as brainliest?
The answer is 7b+35 because the seven multiplies by the b and the 5 meaning that you multiple the number that’s on the outside with what’s on the inside and be b is a variable it cannot be multiplied so you combine 7 and b which gives you 7b and then you multiply 7 and 5 which gives you 35
