Write an
equation for the circle with centre (0,0), if (12,5) lies on its circumference

Answers

Answer:

x² + y² = 169

Step-by-step explanation:

The equation of a circle centred at the origin is

x² + y² = r² ( r is the radius )

Given (12, 5 ) lies on the circumference , then the point will satisfy the equation.

Substitute (12, 5 ) into the equation

12² + 5² = r²

144 + 25 = r²

169 = r²

Then equation of circle is

x² + y² = 169

If

represents the number of hours required to travel
x
miles, what is the domain of the function,
f
(
x
)
?

Answers

Given that f(x) is a function that represents number of hours required to travel, the domain of the function is: distance travelled in miles (x)

Recall:

In a relation that is a function, the domain of the function is the set of input values (x-values).The range of the function is the set of output values (y-values or f(x)).

Thus, given that f(x) is a function that represents number of hours required to travel, therefore:

x = input values (domain) = distance travelled in milesf(x) = output values (range) = number of hours.
