(-1,-9) because if we substituted 1 into x y would be 9 and if we substituted 1/2 into x y would be 3 but if we substituted -1 into x y would be 1/9 so therefore that value is incorrect
reflection of
over the y axis we get 
Step-by-step explanation:
We need to find the reflection of f(x)=sqrt x over the y axis
So, reflection over y- axis
If the function f(x) is transformed over y-axis then the new function g(x) will be 
So, finding reflection of
over the y axis we get:

So, reflection of
over the y axis we get

The height of the balloon from ground is 100√3m.
Justification:
<u>The above situation forms a right angled triangle ABC in which length of cable 200m indicates the hypotenuse side and angle of inclination is 60°</u>.
So, In ΔABC
sinθ = p/h
sin60° = AB/AC
√3/2 = AB/200
AB = 200√3/2
AB = 100√3m.
<u>Note</u>: Figure attached with answer.
Since each cube has a volume of 1 cubic meter and the box and fit 48 unit cubes the volume of the box is 48 cubic meters.
