Write the equation in standard form of a circle with center (-7,2), tangent to the y-axis.
Vesna [10]

Answer:

(x+7)^2+(y-2)^2=7^2

Step-by-step explanation:

Tangent to y-axis means that the side of the circle TOUCHES the y axis.

Since the center is at (-7,2) and it touches the y axis, we can figure out the radius. It goes from (-7,2) to y-axis. Horizontally, the center is 7 units left of y-axis, so that is the radius -----  7 units

The standard form of a circle is:

(x-h)^2+(y-k)^2=r^2

Where

(h,k) is the center

r is the radius

Putting the information into the form, we have:

(x-h)^2+(y-k)^2=r^2\\(x-(-7))^2+(y-(2))^2=7^2\\(x+7)^2+(y-2)^2=7^2

THis is the standard form.

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.
