Answer:
874.6
Step-by-step explanation
Profit = Sales - Costs
Profits by day:
Mon:
225 - (225*0.12) -9 = 189.0
Tue
260 - (260*0.12) -9 = 219.9
Wed
230 - (230*0.12)-9 = 193.4
Thu
180 - (180*0.12) - 9 = 149.4
Fri
150 - (150*0.12) -9 = 123.0
Total:
189+219.9+193.4+149.4+123 = 874.6
The question ask to find the rate of change of the distance from the paticle to the origin at this instant where as a particle is moving along the curve y = 5sqrt(5x+4) and base on my calculation, I came up with an answer of 254/sqrt(226). I hope you are satisfied with my answer and feel free to ask for more
10 1/3= 31/3
31/3= 93/9
11 5/9= 104/9
93/9 + 104/9 = 197/9
197/9= 21 8/9
your answer is 21 & 8/9
Good Luck
