why polar coordinates seem better suited for circular-type functions, while the rectangular coordinate system seems better suite
irina1246 [14]
Because "circular-type" functions can be more easily described by the periodic functions \sin and \cos, which are deeply involved in the behavior of "circular-type" functions. Also, using a polar coordinate plane allows you to draw graphs of equations that typically aren't functions.

For example, the unit circle requires two equations to be graphed to fully represent the circle in the rectangular coordinate plane.

x^2+y^2=1\implies y=\pm\sqrt{1-x^2}

On the other hand, in polar coordinates, substituting x=r\cos\theta and y=r\sin\theta reduces this to a constant function,

(r\cos\theta)^2+(r\sin\theta)^2=r^2(\cos^2\theta+\sin^2\theta)=r^2=1\implies r=1 (since by definition, r\ge0)

timofeeve [1]
In this question, every cups will be filled with 4 ounces yogurt. That mean, the lowest possible of the cups weight would be 4 ounces. After that the customer can the topping without exceeding 6 ounces of total weight. Since it total weight, that means from the 6 ounces there should be 4 ounces of yogurt. Then the maximum weight is 6 ounces
Minimum weight is 4 ounces and maximum weight is 6 ounces, so the answer would be 4,5,6 or any number between 4-6

Use complete sentences to explain how the coordinate plane is a useful tool for geometric proofs.
Masja [62]

the facilitate verification is a proof of a geometric hypothesis which utilizes "summed up" indicates on the Cartesian Plane make a contention. 


The strategy for the most part includes doling out factors to the directions of at least one focuses, and afterward utilizing these factors in the midpoint or separation equations . 


For instance, the accompanying is an arrange evidence of the Triangle Midsegment Theorem , which expresses that the fragment interfacing the midpoints of two sides of a triangle is parallel to the third side and precisely a large portion of the length.
