Final answer:
To find the value of a when p(a) = 13, use the given function p(a) = 3a - 10 and set it equal to 13. Solve for a to find the value.
Step-by-step explanation:
To find the value of a when p(a) = 13, we need to set the function equal to 13 and solve for a.
Using the given function p(a) = 3a - 10, we have:
3a - 10 = 13
Adding 10 to both sides of the equation:
3a = 23
Dividing both sides by 3:
a = 23/3
So, the value of a when p(a) = 13 is approximately 7.67 (rounded to two decimal places)
