Circle

Step-by-step explanation:

The given equation is

We know the standard equation of a circle is given by

Where, (h,k) is the center of the circle and r is the radius.

We can rewrite the given equation in this form

Hence, the center of the circle is (0,0) and radius is 4.

Thus, the given equation represents a circle.

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

step-by-step explanation:

example 2 – simplify: step 1: completely factor both the numerators and denominators of all fractions. step 2: change the division sign to a multiplication sign and flip (or reciprocate) the fraction after the division sign; essential you need to multiply by the reciprocal. step 3 : cancel or reduce the fractions.
