Ok so
8000=cost
profit-8000
then
another cost is 15rand per mug
but profit of 35 rand
35-15=20
profit of 20rand per mug
profit=R20m-R8000
where m=number of mugs sold
(R20 means 20 rand)
f(m)=R20m-R8000
break even means cost=earned
basically, when profit=0
0=R20m-R8000
add 8000 to both sides
R8000=R20m
divide both sides by 20
400=m
break even is 400 mugs
graph should be easy enough
put a point at (0,-8000) and at (400,0) then connect them
profit
f(x)=R20x-R8000
break even is 400 mugs
put points (0,-8000) and (400,0) and connect them
Slope is found when you put y2-y1/x2-x1. So your equation would be (-2)-2/6-3.
That answer would be -4/3. Nothing can be simplified further, so that is your answer
Area of the whole circle = 3.14 * 7.5^2
area of the sector = (3.14 * 7.5^2 * 210) / 360
= 103 cn^2 to nearest whole number
Step-by-step explanation:
D 28 miles you want to multiply by 4 so 7x4 =28
