Answer:
(x-4)^2
square root everything in the equation
Amount of commission received by Steve for the first 4 sales of the month = $500
Amount of commission received by Steve for the next 6 sales of the month = $600
Amount of commission made by Steve
for the first 10 sales of the month = (500 + 600) dollars
= 1100 dollars
Average commission received by Steve per sale during the month = 1100/10 dollars
= 110 dollars
So the average commission received by Steve for a single sale during the month is $110. I hope the procedure is clear enough for you to understand.
Answer:
Angle rotation 120 ,90,60,45
The numbers are 17 and 13. 17+13=30 and 17-13=4.
Answer:
4cotα=tanα
4(1/tanα)=tanα
(4/tanα)=tanα
cross multiply
=> 4=tan²α
√4=√tan²α
±2=tanα
α=arc( tan) |2|
α=63.4° ( in first quadrant)
and
α=180+63.4=243.4 in the third quadrant
since we also found a negative answer( i.e –2) then α also lies in quadrants where it gives a negative value(i.e second and fourth quadrants)
α=180–63.4=116.6° in the second quadrant
α=360–63.4=296.6 in the fourth quadrant
therefore theta( in my case, alpha) lies in all four quadrants and is equal to:
α=63.4°,243.4°,116.6°and 296.6°
