(ii) The scale 1 cm represents 50m can be written in the form 1:k. Find the value of k.
k=
[1]

k = 50

Step-by-step explanation:

The scale 1 cm represents 50m

It means that 1 cm length of pictorial representation of any obejct  is equivalent to 50m in reality.

In scale terms it can be represented in ratio form of a:b

where

a is the length of picture and b is actual length

here length of pictorial representation is 1 cm

and 50m is actual length

thus scale will be  1:50

But is given that The scale 1 cm represents 50m can be written in the form 1:k.

1:50 is same as 1:k

thus

1:50 = 1:k

we know that in ratio

if a:b = c:d

then

a= c  and b = d

Thus,

k = 50 Answer

y = 5x + 17

step-by-step explanation:

a perpendicular line will be the opposite reciprocal slope of the given equation.   the slope given is -1/5 so the opposite reciprocal is 5

find b:

7 = 5 (-2) + b

7 = -10 + b

17 = b

write equation

y = 5x + 17

vertical asymptote .

horizontal asymptote .

step-by-step explanation:

given function is .

vertical asymptote is given by setting

denominator =0

when degree of numerator and denominator are same then divide first term of numerator by first term of denominator to get horizontal asymptote.
