Answer:
4 inches
Step-by-step explanation:
The radius of a circle is its diameter divided by 2.
8/2 = 4
Ans = 4 inches
The given function has no undefined points nor domain constraint. Thus, the domain is:
.
<h3>Domain and Range</h3>
The domain of a function is the set of input values for which the function is real and defined. In the other words, when you define the domain, you are indicating for which values x the function is real and defined. An example, there is a restriction for the domain of fractions. The variable x in the denominator should be different of zero.
While the domain is related to the values of x, the range is related to the possible values of y that the function can have.
In this question, the function
has no undefined points nor domain constraint. Therefore, the domain is: ![-\infty \: < x < \infty](https://tex.z-dn.net/?f=-%5Cinfty%20%5C%3A%20%3C%20x%20%3C%20%5Cinfty)

Answer:
z = -17
Step-by-step explanation:
If the average of x and y is 11, then;
x+y/2 = 11
x+y = 2 + 11
x+y = 22 .... 1
similarly, if average of x, y and z is 5, then;
x+y+z/3 = 5
x+y+z = 3*5
x+y+z = 15
Since x+y = 22
22 + z = 5
z = 5 - 22
z = -17
Hence the value of z is -17
