4) Convert the rectangular coordinate (1/2,-√3/2) to a polar coordinate

step-by-step explanation:

point m is on plane r

one way is to plot 2 points and connect them which is what the answer choices seem to be doing

it seems to be using the y intercept and the slope

y=mx+b, m=slope, b=y-intercept (where the line hits the y axis)

slope=rise/run

y-intercept is where the line croses the y axis which is the y value where x=0

you seem to have given the wrong slope (you didn't put a number in front of te x, it should be 2/3 or 3/2 looking at the answer options)

y=? x-1

m=? because of your fault

b=-1

so it has a slope of ? and y intercept of -1, meaning it pases through (0,-1)

so draw point (0,-1) (so answer is one of the first 2 option)

if slope is 2/3, then go up 2 and right 3 then draw line through those 2 points

if slope is 3/2, then go up 3 and right 2 then draw line through those 2 points

believe that your asking for two answers. the volume of the pyramid is 15 cubic centimeters and if the slant increases by 4 centimeters and its hheight increases by 2 centimeters the volume increases by 6 centimeters because the answer would be 21. 21-15=6. formula to get the volume of a pyramid is v=1/3*(l*w)*h. i could be wrong.
