Answer:
1) Jina is not a member of the Music Club.
2) Three students are a member of the Music Club but not the Math Club.
3 Mary and Dan are in all three clubs.
Step-by-step explanation:
Look at the diagram and notice how each club has its own circle. If a student is in that circle, then they are a member of that club. When circles overlap, that overlap space means that a student is a member of two or all three clubs, depending on how many and which circles overlap.
1) Looking at Jina's location on the diagram, she is in the overlap between the math and chess club circles. However, her position does NOT overlap with the Music Club circle, therefore she is not a member of the Music Club.
2) Let's look at the students of the Music Club circle and its overlaps with the Chess Club circle, but NOT the overlaps with the Math Club circle. We can see that Lucy, Josh, and Juan are in these locations, therefore there are three students who are members of the Music Club but not the Math Club.
3) To find which students are in all three clubs, you would look at the middle of the diagram where all three circles overlap. The students listed in this location are Mary and Dan, therefore they are in all three clubs.

What is Rational expressions ?
- Rational expressions represent the relationship between two polynomials. It means that the numerator and denominator are both polynomials.
- It is an algebraic expression ratio with an unknown variable, similar to a fraction. We can, however, simplify this type of expression with the aid of a calculator.
- You've probably heard of rational numbers, which are written in the form p/q. In contrast, rational expressions are the ratio of two polynomials.
- To find the root or zero of a polynomial expression, we must first make it equal to zero. To find the zeros of rational functions or expressions, however, only the numerator must be set to zero after the expression has been reduced to its simplest terms.

Answer:
T=12500-0.25y
Step-by-step explanation:
Step one:
given data
The value of the car is $12500.
let the value of the previous year be T
let the number of years be y
25% will be 0.25----this is equivalent to the gradient
The expression for the change in price can be represented linearly using the equation of a straight line,
y=mx+c
but since the price is reducing the expression becomes
y=-mx+c
Now, in this situation the expression for the cost after y years is
T=-(0.25y)+12500
rearrange
T=12500-0.25y
<u>The expression is T=12500-0.25y</u>
Answer:
11 units
Step-by-step explanation:
A = pi x r^2
A = pi x 15^2
A = 225 x pi
A = 706.9ft^2 (1 dp)
