Convert the cartesian equation x2 +y2=16 to a polar equation

Mathematics

VARVARA [1.3K]4 years ago
3 0
X^2+y^2 = 16
can be written as
(x-0)^2+(y-0)^2 = 4^2

We see that the second equation is in the form
(x-h)^2 + (y-k)^2 = r^2

where
(h,k) = (0,0) is the center
r = 4 is the radius

The polar form of the equation is simply r = 4. Why is this? Because the radius is fixed to be 4 no matter what happens with theta. As theta goes from 0 to 360, the points generated all form a circle centered at (0,0) with radius 4. 

Answer: r = 4

write an expression that describes the number of points scored on touchdowns t and points after touchdowns p by one team in a ga
Len [333]
A touchdown is scored 6 points for each touchdown and the points made after a touchdown is scored 2 points each. We are given the following variables:

t = number of touchdowns
p = number of points after a touchdown

Total score = 6t + 2p

Where 6 times t is the total score given by the number of touchdowns multiplied by 6 points, the same goes for the expression 2p.
