Answer:
<em>The domain of f is (-∞,4)</em>
Step-by-step explanation:
<u>Domain of a Function</u>
The domain of a function f is the set of all the values that the input variable can take so the function exists.
We are given the function
It's a rational function which denominator cannot be 0. In the denominator, there is a square root whose radicand cannot be negative, that is, 4-x must be positive or zero, but the previous restriction takes out 0 from the domain, thus:
4 - x > 0
Subtracting 4:
- x > -4
Multiplying by -1 and swapping the inequality sign:
x < 4
Thus the domain of f is (-∞,4)
The answer is b. 25.12
because we are finding the amount of rope to go around the circle, we are looking for the circumfrence of the circle, and the formula for the circumfrence of the circle is diameter(pi). because the radius of the circle is 4 inches, the diameter iss 8 inches because the diameter is 2(radius) and using multiplication, we can find the the circumfrence to be 25.12 inches
