A scale for a scale drawing is 10cm:1mm. which is larger the actual object or drawing explain

Answers

If I'm understanding your question, the drawing is 10cm and for every 10cm, the drawing is etched 1mm. This means that no matter how big the drawing gets, the actual object will always be bigger since it's 10cm larger always than the drawing. Hope this helped!

Who knows the answer to this question?

Answers

Every function associates input values with output values. The domain of a function is the set of all the inputs the function accepts.

You will basically always find your function graphed with the inputs on the horizontal axis and the outputs on the vertical axis. This means that every point on the graph has coordinates $(x,f(x))$ , and the domain is the set of all the x values.

The points on your red line have all coordinates $(d,70)$ , where d starts from 0 and ranges up to 12. So, the domain of the function is $[0,12]$
