Answer:

Option B. (x - h)² + (y - k)² = r²

Step-by-step explanation:

Equation of a circle which passes through a point P(x, y) and center at (0, 0) then the equation of the circle is represented by

x² + y² = r²

If center of the circle is moved from origin (0, 0) to (h, k) then we have to find the equation.

(x - h)² + (y - k)² = PQ² = r² [Distance between two points P and Q]

Therefore option B is the correct answer.

Aleonysh [2.5K]

Answer:

16320

solution: 12 / 1/4 = 3.

4 divided by 1/4 = 20

4 1/4 divided by 1/4 = 17.

3 x 20 x 17 =

List of subsets of each set {1,3,5,7}

agasfer [191]

ANSWER

{},{1},{3},{5},{7},{1,3},{1,5},{1,7},{3,5},{3,7},{5,7},{1,3,5},{1,3,7},{3,5,7},{1,5,7},{1,3,5,7}

EXPLANATION

The given set is {1,3,5,7}.

This set has

${2}^{n} = {2}^{4} = 16$

subsets.

Where n=4 is the number of elements in the set.

Recall that the null set is a subset of every set and every set is a subset of itself.

The subsets are:

{}

{1},{3},{5},{7}

{1,3},{1,5},{1,7},{3,5},{3,7},{5,7}

{1,3,5},{1,3,7},{3,5,7},{1,5,7}

{1,3,5,7}

Is y = 0 the asymptote of all functions of the form f(x) = ab^x? Explain your reasoning.

xeze [42]

Y=0 would be a horizontal line. An asymptote is a line that a function approaches, but never reaches. Exponential functions such as these are a smooth curve. If both numbers are positive numbers greater than or equal to 1, the curve increases. If at least one of the numbers is a positive number between 0 and 1, the curve decreases. If a is a negative number, the curve decreases as well. If either a or b is zero, then the graph would stay constant at 0. However, as long as neither a nor b is zero, then this graph will never touch that point. The only way to get an answer of y=0 is to multiply by 0. If neither a nor b is zero, this won't happen.

*BRAINLIEST* (Easy Question: Warm UP) Find a positive solution to each equation: x2 = 9/4?

prisoha [69]

Answer:

A

Step-by-step explanation:

Given

x² = 9/4

Solving

Take the square root on both sides
√x² = √9/4
⇒ x = 3/2
Option A is the correct option.
