Answer:
The radius is: 1
Step-by-step explanation:
The equation of a circle in center-radius form is:

Where the center is at the point (h, k) and the radius is "r".
Given the equation of the circle:

You can identify that:

Then, solving for "r", you get that the radius of the circle is:

Answer:
and
.
Step-by-step explanation:
We have been given a system of equations. We are asked to solve our given system.


From equation (1), we will get:

Upon substituting this value in equation (2), we will get:





Now, we will substitute
in equation (1).



Therefore, the point
is solution for our given equation.
Answer:
The best way to know weather the formula y=x⁴-4x³+3x² is growing or not, is by graphing it.
As you can see in the attached picture:
- For -inf<x< 0 the graph decreases.
- For 0<x<0.634 the graph is growing
- For 0,634<x<2.366 the graph decreases
- For 2.366<x<+inf the graph is growing.
Therefore, the polynomial grows in the intervals stated before.
Answer: There are approximately 8 restaurants that have hawaiian pizzas on their menus.
Step-by-step explanation:
Total number of pizzas restaurants in Gotham = 100
Percent of pizza orders in Gotham are for hawaiian pizzas = 7.5
Number of Gotham restaurants that have hawaiian pizzas on their menus is given by

So, there are approximately 8 restaurants in Gotham that have hawaiian pizzas on their menus.
