= 14r+11</em>
the constant of proportionality
Step-by-step explanation:
proportional relationships are relationships between two variables where there are ratios equivalent. another way to think about them is that in a proportional relationship that one variable is always constant value times the other that constant is known as the constant of proportionality
Answer:
Step-by-step explanation:
The trigonometric function;
has zeroes at 
where 
is an odd integer.
The trigonometric function; 
. This also has zeroes at where is an odd integer.
-15 so that is negative. so that is negative 15÷15 so 15 ÷15 is 1 so it would be -15÷-15=-1
