Answer:

D.

Step-by-step explanation:

A function, by the easy-to-understand definition, is a relation where no x values are shared.  The only set where each x value is different is in D.  All the other sets share the same x value.  Example:  Set C has coordinates (-2, 1) and (-2, 2).  The x coordinates are the same, so this isn't a function.  It is only a relation.

Consider a circle whose equation is x2 + y2 – 2x – 8 = 0. Which statements are true? Select three options.
Alla [95]

Considering the given equation of the circle, the true statements are given as follows:

  • The radius of the circle is of 3 units.
  • The center of the circle lies on the x-axis.
  • The circle has the same radius as the circle with equation x² + y² = 9.

<h3>What is the equation of a circle?</h3>

The equation of a circle of center (x_0, y_0) and radius r is given by:

(x - x_0)^2 + (y - y_0)^2 = r^2

The equation given is:

x2 + y² - 2x - 8 = 0.

Completing the squares, the equation is given as follows:

(x - 1)² + y² = 8 + 1

(x - 1)² + y² = 9.

Researching the problem on the internet, the true statements are:

  • The radius of the circle is of 3 units.
  • The center of the circle lies on the x-axis(y_0 = 0).
  • The circle has the same radius as the circle with equation x² + y² = 9.

Anna has been studying a type of bacteria that triples every month. Originally, there were 4 bacterial cells. She wants to know
bija089 [108]

As per the given information;

Bacteria triples every month.

Originally, there were 4 bacterial cells.

We are suppose to find how many there will be after 15 months.

Hence we can say , the number of bacteria after n month can be given using the exponential growth function

a_n=4*3^n

So number of bacteria after 15 month will be

a_{15}=4*3^{15}
