Find all the real square roots of –(9/16)
2 answers:
Answer:
Option A. no real root.
Step-by-step explanation:
We have to find the real square roots of .
We can write the term as
= [ As we know √(-1) = i ]
Since it's an imaginary number therefore we can say square root of any negative number is an imaginary number.
Therefore Option A. no real roots is the correct option.

Answer:
The function is y = 40 * 2^(x/2)
The graph is in the image attached
Step-by-step explanation:
The function that models this growth is an exponencial function, that can be described with the following equation:
y = a * b^(x/n)
Where a is the inicial value, b is the rate of growth, x is the time and n is the relation between the time and the rate (the rate occurs for every two hours, so n = 2).
Then, using a = 40, r = 2 and n = 2, we have:
y = 40 * 2^(x/2)
If we plot this function, we have the graph shown in the image attached,
It is an exponencial graph, where the value of y increases very fast in relation to the increase of x.
