Write down each of the following statement using the symbol a and the constant of pro-
portionality, k.
(a) p is directly proportional to q.
(b) y varies directly as the square of x.
(c) y varies directly as the cube of x.
(d) T varies directly as the square root of l.
(e) y is directly proportional to the cube
root of x.

Step-by-step explanation:

Option (e) is the right answer.

step-by-step explanation:

if you want to solve percent error follow these steps.

1. subtract the accepted value from the experimental value.

2. take the absolute value of step 1.

3. divide that answer by the accepted value.

4. multiply that answer by 100 and add the % symbol to express the answer as a percentage.

if you want to solve percent of change just do this.

1. work out the difference (increase) between the two numbers you are comparing.

2. divide the increase by the original number and multiply the answer by 100. if your answer is a negative number then this is a percentage decrease.

hope this : )
