Determine which equation is belongs to the graph of the limacon curve below.
[-5,5] by [-5,5]
a. r= 4 + cose
b. r= 2 + 3 cose
c. r= 3 + 2 cose
d. r= 2 + 2 cose

Find the value of a. the diagram is not to scale. a quadrilateral is drawn. the upper and lower sides are parallel. the interior angle in the upper left corner is labeled a degrees. the angle in the upper right corner is labeled 113 degrees. the angle in the lower right corner is labeled b degrees. the angle in the lower left corner is labeled 36 degrees. a. 36 b. 144 c. 54 d. 126

Which graph shows a function with a range of all real numbers greater than or equal to -1

Can someone check if i did this right since i really want to make sure it’s correct. if you do you so much
