Twenty rivits are used to fasten two steel plates together. the plates are 3.4m long, and the rivits are equally spaced, with the rivit at each end. find the distance between the rivits.

distance = 0.17 m/rivet

Step-by-step explanation:

if the plates all are riveted along its length then the distance between the rivets is

distance = total distance of the plates/ number of rivets= 3.4 m/20 rivets = 0.17 m/rivet (distance between the centre of the rivets respect to each other without considering the diameter)

  y= -3x is the required function.

step-by-step explanation:

we have been given a table:

x             y

0             0

1             -3

3             -9

-2             6

we can see that the values of y is -3 times the value of x

hence, the function would be: y= -3x.

put the values of x will give the same y as in the table that means function is satisfying the given table.
