Answer:
a) y = 1500 * 3^x
Step-by-step explanation:
This equation indicates that the number of songs available, y, is equal to the initial number of songs (1500) multiplied by 3 raised to the power of the number of years, x. This reflects the expectation that the collection of songs will triple each year.
Answer:
To find the perimeter of the original rectangle, we first need to find the dimensions of the rectangle.
Let's assume the length of the original rectangle is L cm and the breadth is B cm.
According to the given information, if the length is decreased by 4 cm, the new length becomes (L - 4) cm. Similarly, if the breadth is increased by 2 cm, the new breadth becomes (B + 2) cm.
We are told that this new rectangle with dimensions (L - 4) cm and (B + 2) cm is actually a square with the same area as the original rectangle.
The area of a rectangle is given by length multiplied by breadth. So, the area of the original rectangle is L * B square cm.
The area of the new square is equal to the area of the original rectangle. Therefore, we can set up the equation:
(L - 4) * (B + 2) = L * B
Expanding the equation:
LB - 4B + 2L - 8 = LB
Simplifying the equation:
2L - 4B - 8 = 0
2L = 4B + 8
L = 2B + 4
Now that we have an equation relating the length and breadth of the original rectangle, we can find the perimeter.
The perimeter of a rectangle is given by the formula: 2 * (length + breadth).
Substituting the value of L from the equation above, we get:
Perimeter = 2 * [(2B + 4) + B]
Perimeter = 2 * (3B + 4)
Perimeter = 6B + 8
Therefore, the perimeter of the original rectangle is 6B + 8 cm.

2. Is S a function? Explain your reasoning.
Answer:
HOPE THIS HELPS!!
Step-by-step explanation:
1. The domain and range of relation S are as follows:
Domain: The domain refers to the set of all input values in a relation. In this case, the domain of S is {3, 2, 1}, which corresponds to the first element of each ordered pair in the relation.
Range: The range refers to the set of all output values in a relation. In this case, the range of S is {4, 3, 2, 1}, which corresponds to the second element of each ordered pair in the relation.
2. No, relation S is not a function.
To be considered a function, each input value (or element in the domain) should have only one corresponding output value (or element in the range). However, in the given relation S, the input value 2 is associated with both the output values 3 and 1.
Since one input value is associated with multiple output values, S fails the definition of a function.
