Given b(x) = |x+4| , what is b(-10)
2 answers:
Answer:
Step-by-step explanation:
We are given the function:
We want to find b(-10). Therefore, we must plug -10 in for each x.
Solve inside of the absolute value symbol. Add 4 to -10 ⇒ -10+4= -6
Absolute value represents how far away a number is from 0. It is always positive.
-6 is 6 away from 0. Therefore, the absolute value of -6 is 6.
b(-10) is equal to 6.

<h3>How to get the angle?</h3>
We know that the terminal side passes through a point of the form (√2/2, y).
Notice that the point is on the unit circle, so its module must be equal to 1, so we can write:
We know that y is positive because the point is on the first quadrant.
Now, we know that our point is:
(√2/2, 1/√2)
And we can rewrite:
√2/2 = 1/√2
So the point is:
( 1/√2, 1/√2)
Finally, remember that a point (x, y), the angle that represents it is given by:
θ = Atan(y/x).
Then in this case, we have:
θ = Atan(1/√2/1/√2) = Atan(1) = 45°
