A whole number? ok. 24x10^4. usually though you would use standard form so it would be 2.4x10^5
To travel to Orlando is time=300/70=4.29 hours
x=hours traveller
Since there is 30 miles left in trip, the distance already traveled is 300-30=270
Set proportion
300/4.29=270/x
300x=(270)(4.29)
300x=1158.3
300/300x=1158.3/300
x≈3.86 hours ☆☆☆☆☆☆☆SOLUTION
Cos(x+2x) + cosxcos2x - sinxsin2x
whatttttttt? i have no idea what that is
You probably did 350*tan(28) instead which gave the wrong value of y.
You can verify this answer by testing if the 3 values form a pythogorean triplet.
Which gives an error ~0.1%, consistent with our 4 s.f. rounding above.
