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.

Answer:
£2.00
Step-by-step explanation:
Badly worded, as they oftena are! But to me it means
30% spent
60% saved (I.e also taken away and put somewhere else)
10% leftover equals 20p
So 20p equals 10% of what she originally had, so 100% must be £2.00, does that make sense?
Answer:
f(x)=2x-10 ______(given)
f(x)=8 _______(given)
Therefore, according to the above problem
2x-10=8
2x=10+8
2x=18
x=18/2
<u>x=9</u>
<h3><u>9</u> is the right answer.</h3>
