Answer:
6
Step-by-step explanation:
Given data:
x=area
f(x)=the length of one side of the square
Also the model of f(x)= 
Now determining length of one side of the square f(x), when Area x of square is 26:
Putting the value x=26 in given equation of f(x)
f(x)= 
= 
= 5 +1
= 6
Hence length of one side of the square f(x) is 6, when Area x of square is 26 !
1. Place your compass point on X and measure the distance to point Y. Swing an arc of this size above (or below) the segment.
2. Without changing the span on the compass, place the compass point on Y and swing the same arc, intersecting with the first arc.
3. Label the point of intersection as the third vertex of the equilateral triangle.
4. Use you straight edge and connect the points.
Answer:
720 kph
Step-by-step explanation:
The ratio of times is ...
new time/original time = (1 2/3 h)/(5 h) = (5/3 h)/5 h) = 1/3
For the same distance, the ratio of speeds must be the inverse of this:
new speed/original speed = s/240 = 1/(1/3) = 3
s = 240(3) = 720 . . . . km/h
The aeroplane must travel at a speed of 720 km/h.
