Example 2 Converting inches to centimeters in inch ,
an obvious observation is that as the number of inches, 1, in a measurement of a particular
length
ali need to determine
how many centimeters long
a particular table measures and all I have
increase, the length's measurement in centimeters, sc will also increase. So 1, the number of
width of my calculator to be sav. inches and about et sentimine the linear model that relates inches
iniches, is directly proportionalement tine cumiperters centimeters. I used the ruler to measure the
to centimeters and then use the model to find the length of the table in centimeters if it has a label
on the bottom that indicates the length to be 84 inches.

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.

(sin 42)/31. = sinx)/37

sinx = 37 (sin42)/31

= 37× 0.66/31 = 0.787

x= 51.9

other angle opposite to y = 180-51.9-42

= 180- 93.9 =86.1

so

sin42)/31 = sin 86.1)/y

0.021 = 0.997 /y

y= 0.997/0.021 =47.47

answer: haha (: i’ll go see what it is
