The scale on the map is stated as 1 : 2. a main road connects two towns which are 28 kilometres apart. how far will it be on the map, in centimetres, between the two towns along the main road

The distance on the map between the two towns=14 cm

Step-by-step explanation:

Step 1

Express the scale as;

1:200,000 this means that 1 cm on the map represents 200,000 cm on the road, 1 cm:200,000 cm

Step 2

Convert 28 kilometers to m

1 meter=1,000 kilometers

28 kilometers=28×1,000=28,000 meters

Convert 28,000 meters to centimeters

1 meter=100 centimeters

28,000 meters=28,000×100=2,800,000 centimeters

Step 3

Using the scale factor of 1:200,000 convert 2,800,000 cm on the road can be converted to map measurements as follows;

Distance on the map=scale factor×distance on the road

where;

scale factor=1/200,000

distance on the road=2,800,000 cm

replacing;

Distance on the map=(1/200,000)×2,800,000

Distance on the map=14 cm

The distance on the map between the two towns=14 cm

The given polynomial is in factored form. So in order to find the zeros of the polynomial, set each factor equal to zero and find the value of x. All such values of x will be the zeroes of the polynomial.

So,
x - 6 = 0 
⇒ x = 6

x - 2 = 0
⇒ x = 2

x + 7 =0
⇒ x = -7

Thus the zeros of the given function are x = 6, x = 2 and x = -7
