Question

The aspect ratio is used when calculating the aerodynamic efficiency of the wing of a plane for a standard wing area, the function A(s)=s^2/36 can be used to find the aspect ratio depending on the wingspan I’m feet. If one glider has an aspect ratio of 5.7, which system of equations and solution can be used to represent the wingspan of the glider? Round solution to the nearest tenth if necessary.

Y=s^2/36 and y=5.7;14.3 ft
Y=5.7s^2 and y=36; s=2.5ft
Y=36s^2 and y=0; s=0.4 ft
Y=s^2/36 +5.7 and y=0; s=5.5 ft

Answer 1

Answer: y=s^2/36 and y=5.7;s=14.3ft or A

Explanation:

Answer 2

Option 1 - Y=s^2/36 and y=5.7;14.3 ft

Explanation:

Given : The aspect ratio is used when calculating the aerodynamic efficiency of the wing of a plane for a standard wing area, the function
`A(s)=(s^2)/(36)` can be used to find the aspect ratio depending on the wingspan I’m feet. If one glider has an aspect ratio of 5.7.

To find : Which system of equations and solution can be used to represent the wingspan of the glider?

Solution :

The required function is
`y=(s^2)/(36)` ,

One glider has an aspect ratio of 5.7.

i.e. y=5.7

Substitute in equation,

`5.7=(s^2)/(36)`

`s^2=5.7* 36`

`s^2=205.2`

`s=√(205.2)`

`s=14.3`

Therefore, the solution of equation is 14.3 ft.
