Find the domain of the function f of x equals square root of the quantity twelve x plus twenty four
Orlov [11]
The domain is related to the x-value of the function. In this case, the goal of finding the domain is to make sure that the number under the radical sign is positive. The number that makes the function under the radical sign is -2. Hence this is the minimum number and the domain is from -2 to positive infinity.

In circle P, BC = 24 ft. What is the length of ABC
natulia [17]

Answer:

C) 22 pi

Step-by-step explanation:

Here the diameter of the circle = 24.

Therefore, radius of the circle = 24/2 = 12 ft

Here we have to use the formula to find the arc length.

Arc length = (central angle / 360) * 2*pi*r

Central angle ABC = 360 - 30 = 330 degrees and radius (r) = 12

Now plug in these values in the formula, we get

Arc length ABC = (330/360) *2*pi*12

Now we have to simplify it.

= 11/12 *2 *pi*12

= 11*2*pi

Arc length of ABC = 22pi

Therefore, the answer is C) 22 pi

Hope you will understand the concept.

Thank you.
