Convert the equation r equals negative 14 cosine thetar=−14cosθ to cartesian coordinates. describe the resulting curve.

Multiply the equation by r to get

... r² = -14·r·cos(θ)

Then make the usual substitutions:

x² +y² = r²

x = r·cos(θ)

This gives

... x² +y² = -14x

... x² +14x +49 +y² = 49 . . . . . add 49+14x

... (x +7)² + y² = 49 . . . . . . . . . equation of circle of radius 7 with center (-7, 0)

x = 25/2304

step-by-step explanation:

the median here is 25. your lowest value is 14 and highest value is 48. to find the third quartile, find the medium number in between 25 and 48 which would be 42 i believe.
