Answer:

29.4

Step-by-step explanation:

The meal costs $30

Describe the continuity of the graphed function. Select all that apply.
victus00 [196]

Using continuity concepts, it is found that the correct options are:

  • The function is continuous at x = -4.
  • The function has an infinite discontinuity at x = -1.

-----------------------------

A function f(x) is continuous at x = a if:

\lim_{x \rightarrow a^{-}} f(x) = \lim_{x \rightarrow a^{+}} f(x) = f(a)

-----------------------------

  • At x = -4, there are no changes in the definition of the function, thus, it is continuous.
  • At x = -1, we have that:

\lim_{x \rightarrow -1^-} f(x) = 0

\lim_{x \rightarrow -1^+} f(x) = f(1) = 1

  • A different definition depending on the which side of -1 the function is, thus, it is a jump discontinuity.

Circle A has a radius of 21 meters . Circle B has a radius of 28 meters. Find the circumference if each circle in terms of pi
qwelly [4]

Answer:

Circle A= 42\pi

Circle B =56\pi

Step-by-step explanation:

Circumference of a circle =2\pi r

Since you are given the radius, you put it in place of r

Circle A = 2 *\pi *28\\21*2 = 42\\\\42\pi

                                            Circle B= \\2*\pi *28\\28*2 =56\\56\pi\\\\\\
