Answer:

B. 15 ft.

Step-by-step explanation:

We have been given that the circumference of a circle is 47.1 feet. We are asked to find the diameter of the circle.

We will use circumference of circle formula to solve our given problem.

$C=\pi D$

Upon substituting the measure of circumference in formula, we will get,

$47.1=3.14* D$

Now, we will divide both sides of our equation by 3.14.

$\frac{47.1}{3.14}=\frac{3.14* D}{3.14}$

$15=D$

Therefore, the diameter of our given circle is 15 feet and option B is the correct choice.

Find the limit , picture provided

V125BC [204]

Answer:

d. does not exist

Step-by-step explanation:

The given limits are;

$\lim_{x \to 4} f(x) =5$ , $\lim_{x \to 4} g(x) =0$ and $\lim_{x \to 4} h(x) =-2$

We want to find

$\lim_{x \to 4} \frac{f}{g}(x)= \lim_{x \to 4} \frac{f(x)}{g(x)}$

By the properties of limits, we have;

$\lim_{x \to 4} \frac{f}{g}(x)= \frac{\lim_{x \to 4} f(x)}{\lim_{x \to 4} g(x)}$

This gives us;

$\lim_{x \to 4} \frac{f}{g}(x)= \frac{5}{0}$

Division by zero is not possible. Therefore the limit does not exist.

Two angles are supplementary. The first angle measures 40 degrees. What is the measurement of the second angle

Dmitrij [34]

Supplementary angles add up to 180º
If one is 40º, then the other is (180º-40º) = 140º

None of those choices describes a plane.
choice C is the only example of a plane.
