Consider the scale drawing of a skate park. A skate park has side lengths of 2 feet, 4 feet, 1.5 feet, and 3 feet.

The 2 ft side length of the scale drawing corresponds to a side length of 120 feet for the actual skate park.

What is the scale factor?

What operation will find the dimension of the actual skate park that corresponds to 4 ft on the scaled drawing?

The scale factor is 1/60

we know that

The scale factor is equal to the ratio between the side length of the scale drawing to the corresponding side length in the actual

so

2/120 = 1/60

first one is a: renaming a fraction. second one is c: de-c

step-by-step explanation:

my explanation is that these were the answers on edg : )

solution:

the given function is ,

      =

the three roots of this quadratic function is , 0 ,8 and 10.all the roots are real and rational.

if a quadratic equation is of the form ,

sum of the roots = a + b +c= 0+8+10=18=  

product of roots taken two at a time = a b + b c+ c a = 0+80+0=80 =  

product of roots = a b c = 0=  

there are 11 doors in a hall starting from 0 to 11.the entry in the hall is permitted through gate number 0 and exit is allowed through only gate number 8 and 10.so, three roots(0,8,10) of quadratic function is given by entry and exit route of this hall.
