Answer:

B.  (x - 2)^2 + (y + 2)^2 = 4.

Step-by-step explanation:

The general form of the equation is

(x - a)^2 + (y - b)^2 = r^2 where (a,b) is the center and r is the radius of the circle.

The radius is 2 so r^2 = 4.

The center of the circle is at  (2, -2) so the equation is:

(x - 2)^2 + (y + 2)^2 = 4.

Rewrite the following radical expressions as equivalent exponential expressions. <br> a. √5
vivado [14]

Answer:

So in exponential form \sqrt{5} will be equivalent to 5^{\frac{1}{2}}

Step-by-step explanation:

We have given the expression in radical form as \sqrt{5}

We have to find its equivalent in exponential form

We know that if any fraction is in radical form then if we write this in exponential form then in exponential form the exponent come inverse of its number

So \sqrt{5} can be written as 5^{\frac{1}{2}}

So in exponential form \sqrt{5} will be equivalent to 5^{\frac{1}{2}}

Find the absolute maximum value for the function f(x) = x^2 − 4, on the interval [–3, 0) U (0, 2].
Andreyy89

Answer:

5

Step-by-step explanation:

The function y=x^2 -4 is

  • decreasing for all x\in [-3,0);
  • is increasing for all x\in (0,2]

(see attached diagram for details).

The maximum value of the function is at endpoints -3 or 2. find y(-3) and y(2):

y(-3)=(-3)^2-4=9-4=5\\ \\y(2)=4^2-4=0

So, the maximum value is 5.
