<span>An airplane travels 2004 km against the wind in 3 hours.
 
Thus, speed = 2004/3 = 668 km/hr ,

and

</span>An airplane travels 2544 km against the wind in 3 hours.
 
Thus, speed = 2544/3 = 848 km/hr

The speed of the plane in still air = (848 + 668 )/2
                                       = 758 km/hr
Thus, the speed of wind is 848 - 758 = 90 km/hr

Sav [38]
S = sally C = Chris J = Joe
sally is one year older than 3 times the age of joe, so
s = 3j + 1
chris is 5 years younger than 6 times the age of jo, so
c = 6j - 5
sally and chris are the same age so
s = c so
3j + 1 = 6j - 5
-3j -3j
1 = 3j - 5
+5 +5
6 = 3j or
3j = 6
3j/3 = 6/3
j = 2

check
s = c
3(2) +1 = 6(2) - 5
6 + 1 = 12 - 5

Answer:

Rx)=1/3x^2

Step-by-step explanation:

A horizontal stretch is simply making the parabola of the parent function wider, it's kind of like changing the slope of a line to make it less steep.

In the graph, the red line is the parent function and the blue line is the horizontally stretched function.  See how the blue line appears to be stretched (horizontally).
