Find the constant of proportionality (r) in the equation y = rr.

r = 1

Step-by-step explanation:

We know that x and y are proportional, with the the equation y = rx representing the proportional relationship. Where r = constant of proportionality

Thus the constant of proportionality would be:

r = y/x

Using any of the given pair of values from the table, say (5.8, 5.8),

r = 5.8/5.8

r = 1

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
