Answer:
The % growth rate is 15.8%.
Step-by-step explanation:
Let the function is given by
, where f(w) is the number of a specific product produced after w weeks.
Now, given for w = 0, f(0) = 190 = a
So, the function becomes
............. (1)
Now, it is also give that at w = 1, f(1) = 220.
So, from equation (1) we get,

⇒ b = 1.15789.
Now, b = 1 + r
⇒ 1.15789 = 1 + r
⇒ r = 0.15789
Therefore, the % growth rate is 0.15789 × 100% = 15.8% (Approx.)
Answer:

Step-by-step explanation:
We are given that fraction

We have to find the expression which is equivalent to given fraction .


Substitute the values then, we get

We know that

Using the property then, we get


This is required expression which is equivalent to given expression.
The answer to this is 19. The reason why is because the median falls between 18 and 20. After that, you have to take the middle number that falls between 18 and 20. In this case, 19.
