A circle is centered at the orgin and contains thr point (-4,-3) . What is the are of this circle?

25π≈78.5 square units

Step-by-step explanation:

The equation for the area of a circle is

We need to determine the radius of the circle. Since the circle is centered at the origin, and the point (-4,-3) is on the circle, we can use the Pythagorean theorem () to calculate the radius of the circle.

Therefore, the radius of the circle is 5. Now we go back and plug it into the equation to find the area of the circle.

the inequality is:

250c+180g≥950

step-by-step explanation:

let c denotes the number of days in a week   miyoko worked as a cryptographer.

and g denotes the number of days in a week she works as a geologist.

now we are given that she earns $250 for every day she works as a cryptographer,and earns $180 for every day she works as a geologist.

now miyoko's goal is to earn more than $950 this week.

hence, the inequality could be represented as:

250c+180g≥950

step-by-step explanation:

descending order means to order the polynomials from the term with the largest exponent to the term with the smallest exponent.  

therefore, the correct answer is d.
