Answer:
The domain of x for the given function, y = + 4, in interval notation is [ 0,
)
Step-by-step explanation:
The given function is y = + 4
We cannot have square root of a negative number.
The minimum of x can be only 0.
The maximum of x can tend to .
Therefore the domain of x in interval notation is [ 0, )

I am too lazy to do question 6 if u want the answer tell me
We have been given a chord and tangent to a circle. We have been minor arc measure that is equal to .
Since we know that angle formed by a secant and tangent of circle is half of the measure of intercepted arc.
We can find intercepted arc by subtracting minor arc measure from 360 degrees because minor and major arcs add up to 360 degrees.
Now we will plug given values in our formula,
Therefore, the measure of d is 121 degrees.
