6 0

Answer:

Step-by-step explanation:

Because this whole problem focuses on the addition of mixed numbers, we can drop the parentheses right now without affecting the problem solution.

The two denominators shown are 4 and 3; the LCD is therefore 12.

Rewriting the problem, we get:

1 3/12 + 3 8/12 + 5 9/12, or

3 + 8 + 9

1 + 3 + 5 + ----------------

This simplifies to 9 20/12, or 10 8/12, or 10 2/3 (answer)

DaniilM [7]

Answer: The required exponential model is $1804(1.04)^t$

Step-by-step explanation:

Since we have given that

Initial cases = 1804

Rate of growth = 4%

Since it is increasing exponentially,

So, it becomes,

$A=ab^t$

Here, a = 1804

b = $1+r=1+0.04=1.04$

So, it becomes,

$A=1804(1.04)^t$

Hence, the required exponential model is $1804(1.04)^t$
