What is a procedural text? a. a document explaining the importance of safety in the workplace b. a manual that describes how a machine is constructed c. a document that gives directions on how to perform a task or operation d. a manual offering advice on how best to use a product or service

Option C is the correct answer.

Step-by-step explanation:

In simple language, procedure is defined as the way or process of making or doing something. In the text format, this information is represented in a sequence of events, denoted by steps. The easiest example of such a procedural text is- recipe.

As per the definition, we can say that option C is the correct answer.

A document that gives directions on how to perform a task or operation.

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.
