Answer:
27
Step-by-step explanation:
Given :
Total number of people : 36
Ratio of people who prefer red to blue
Red : Blue = 3 : 9 = 1 : 3
according to the ratio, for every 4 people, 1 prefers red and 3 prefers blue.
Expressed mathematically:
People who prefer blue = 3/4 of the total number of people
In our case, total number is 36 hence,
People who prefer blue (and hence the number of blue pens he should order),
= 3/4 x 36 = 27
Answer:
2 rays that meet at an endpoint
Step-by-step explanation: A ray starts with a dot, or point and continues on forever with an arrow. There are two rays in that drawing that start at the same endpoint.
The formula to this question is the amount of rows and how many fruit are in each row.
So 4x12=48
There are 48 apples in the apple orchard
and 6x15=90
so 90+48=138
There are 138 pieces of fruit in total
We conclude that both functions f(x) and g(x) are positive on the interval (4, ∞)
<h3>
In which interval both functions f(x) and g(x) are positive?</h3>
On the image we can see two graphs, the blue one is the graph of f(x) and the red one is the graph of g(x).
A function is positive when its graph is above the horizontal line.
For the case of f(x), it is positive on the intervals:
(-∞, -2) and (1, ∞)
And for function g(x), we can see that it is positive on the interval:
(4, ∞)
Now, the interval where both functions are positive is in the intersection between the intervals (in this case is the smaller of the intervals, so it is the correspondent to g(x)), which is (4, ∞)
We conclude that both functions f(x) and g(x) are positive on the interval (4, ∞).

The functions and their descriptions are:
- Polynomial: and
- Logarithm:
- Exponential
<h3>How to describe the functions?</h3>
The functions are given as:
The functions would be described based on the type of function they represent.
Functions that use the "ln" keyword are logarithmic functions, while functions that use the "e" keyword are exponential functions.
