Geometry

Step-by-step explanation:

9). Dimensions of the logo = 4 inch by 6 inch

   ∵ 12 inches = 1 feet

    ∴ 1 inch = feet

   Therefore, dimensions of the logo (in feet) will be,

    feet by feet  Or feet by feet

   Dimensions of the logo which are 6 times larger than the original one.

    Dimensions of the advertisement = feet by feet

                                                            = 2 feet by 3 feet

    Area of the advertisement = 2 × 3

                                                = 6 feet²

10). By the property of similar polygons,

     "Corresponding sides of two similar polygons are proportional"

     If the dimensions of two similar polygons are 'x' and 'kx'

     Ratio of the perimeter of two polygons = = k

     Ratio of area of two similar polygons = = k²

     Ratio of volumes of two similar polygons = = k³

yes because there is exactly one y value for every x value

for function there can't be more than one value for every x value
