The arc length of the circle is 5π/9 units
<h3>How to determine the arc length?</h3>
From the question, we have the following parameters
Angle, ∅ = 5π/9
Radius, r = 1 unit
The arc length (x) is calculated as
x = r∅
Substitute the known values in the above equation
x = 5π/9 * 1
Evaluate the product
x = 5π/9
Hence, the arc length of the circle is 5π/9 units

Using the concept of y-intercept, it is found that the response that is not correct is given by:
B) Replace x with -x.
<h3>What is the y-intercept of a function?</h3>
It is the value of the function when x = 0, hence it is the point (0, f(0)).
In this problem, the function is:
The y-intercept is given by:
If we just replace x with -x, we still have the same expression as above, hence the y-intercept does not change and option B is the answer to this question.

Answer:
270 students is the highest number of students that can attend the Planetarium field trip each day
Step-by-step explanation:
Here, we want to know the highest number of students that can attend the planetarium each day
from the question;
The highest number per group is 15 students
The highest number of group is 18 groups
So the highest number of attendees will be;
15 * 18 = 270 students
11 as many fiction books as non fiction.
Fiction books F, Non Fiction NF
F: NF = 11 : 1
Total ratio 11+ 1 = 12.
Fraction of Fiction books F, = 11/12
Total books = 312.
Fiction books = 11/12 * 312 = 286
Fiction books = 286
