hey give me a break i didn't know how and at least I tried

Learn from Alan's answer how to solve problems of this type.
Let the distance between where he starts from and Austin be L miles
Time taken to get to Austin = L/40 hours
Time taken to return from Austin = L/60 hours
Average speed = total distance/total time = 2L/(L/40 + L/60) → 2/(1/40 + 1/60) → 48 mph
.
explain to me how that is not right
No, not right!.
50 mph
good
Well i guess thats good?
tired and bored but other than that good
Great and you may i ask?
FV = PV (1+i)^n FV= future value =4928.33 PV = present value =4200 i = interest = .0325 n = years
4928.33 = 4200 (1.0325)^n
1.173411 = 1.0325^n
LOG(1.173411) = n LOG (1.0325)
LOG(1.173411)/LOG(1.0325) = n = 5 years
immpretty great and you?
It is the first answer. The reason is because Sqrt(a/b) = Sqrt(a) / Sqrt(b)
So - sqrt(5/9) = - Sqrt(5)/Sqrt(9) = - sqrt(5) /3
Thanks
Is 'x' an angle between legs of 5 and 12 of a right tringle ? Or is 'x' a hypotenuse? Or what?
- sqrt(5/9) = - sqrt 5 / sqrt 9 = - ( sqrt 5) / 3
Be aware of where and how you use brackets.....they change the value of the answer if misplaced !
sin ? = 2/3
arcsin (2/3) = 41.81 degrees
Hi how r you
