If (a,b) is the center and r is the radius of the circle defined by the parametric equationswhat is the value of a+b+r ?
x= 10cos 3t, y= 10sin 3t 0≤t≤ 2pi
This is a bonus problem it is extremely difficult

Answers

Answer 1
Answer:
Those particular parametric equations generate a circle with its
center at the origin (0, 0).  So ' a ' and ' b ' are both zero.

The (radius of the circle)² is (10² + 10²) = 200

Radius = √200

So (a + b + r) = √200 .  ( about 14.1421 )

The significance of the ' 3t ' in the argument of the 'x' and 'y' is just that as
't' goes from zero to 2π , the parametric equations draw the circle 3 times.

Why does x/7= 2???????????
Help!!!!!

Answers

Yes cos you are trying to solve for X 
so you the equation is x/7=2
you can use the opposite of division to solve for x
which will be multiplation
here is how u solve for x
x/7=2
x=7*2
so x is 14
hope the helped :)
14 . because here X is 14 . so 14/ 7 is 2

Why are 1,4,9,16,and 25 sometimes are called perfect square please HELP ME!!!!!!

Answers

They are all perfect squares because if you took the square root of them you will get a single number. Like the square root of 25 is 5 bc 5(5) is 25
16 is 4 bc 4(4) is 16
9 is 3 bc 3(3) is 9
1 is 1 bc 1(1) is 1
& so on & so forth
