Using Pythagoras:-
x^2 = 6^2 + (sqrt18)^2
= 36 + 18 = 54
x = sqrt54 = 3 sqrt6
Answer:
2/3 × 9/5 = 18/15 = 6/5 if need to simplify. or 1 1/5
Step-by-step explanation:
The second option is the answer
The average value is given by

Setting

, you get

, and the integral becomes


I don't know if this helps but an equivalent rate is:Rates that represent the same comparison; for example 90km
2h Fraction<------
and 45km/h Confusing i know
