Answer:
A constant
Step-by-step explanation:
Well, ideally I'd like more details, but a number that doesn't change in a mathematical equation is called a constant.
That is a ratio. If you mean the simplified version, then 2:7
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.)
