Note.......I took care of part 1 only......cos handling both questions on here will be much on me
or.......you can set part 2 as a different question......but applying the same methods for the triangle will definitly work for the rectangle.

A purse is on sale for $25.60. If the original price of the purse was $32.00,what is the percent of discount?
Answer:
20%
Step-by-step explanation:
The dollar amount of the discount is $32.00 - $25.60 = $6.40
Now we need to find what percent of $32.00 is $6.40.
To find what percent a part is from a whole, divide the part by the whole and multiply by 100%.
percent = part/whole * 100%
part = $6.40
whole = $32.00
percent = $6.40/$32.00 * 100%
percent = 20%

Find the average rate of change for the function over the given interval.
2) y = 6x3 - 6x2 - 8 between x = 2 and x = 4
Answer:
132
Step-by-step explanation:
The average rate of change over a function can be given by: f(b)-f(a)/b-a. Where b is the second part of the interval and a is the first part.
y = 6x^3-6x^2-8

The total cost, C, to attend a swim meet for a swimmer competing in x events can be modeled using a linear function. Each swimmer will pay a $3.00 entry fee for each event and $8.00 for lunch. Each swimmer may sign up for a maximum of 5 events. What is the range of the function for this situation?
Answer:
The range is between $11 to $23Step-by-step explanation:
let the total cost be c
let the number of events be x
the linear model is
c=3x+8
therefore for 1 event
c=3(1)+8
c=3+8
c=11
=$11
therefore for 5 events
c=3(5)+8
c=15+8
c=23
=$23
The range is between $11 to $23

1 What is the nature of the roots of the quadratic equation if the value of its discrimman
is zero?
The roots are not real
o the roots are rational and not equal
b. The roots are irrational and not equal d the roots are rational and equal
2. Whal is the ans of symmetry of the parabola y
Answer:
If d is zero, both roots are rational and equal.
Step-by-step explanation:
Quadratic Equations
The standard representation of a quadratic function is:
[tex]f(x)=ax^2+bx+c[/tex]
where a,b, and c are constants.
Solving with the quadratic formula:
[tex]\displaystyle x=\frac{-b\pm \sqrt{b^2-4ac}}{2a}[/tex]
The discriminant is defined as:
[tex]d=b^2-4ac[/tex]
The sign of the discriminant defines the nature of the roots of the quadratic equation as follows:
If d is positive, both roots are real and differentIf d is negative, both roots are imaginary and conjugateIf d is zero, both roots are rational and equal.Which shows the algebraic representation of the phrase and its value when n=4.27

1. Yearly membership with the online music club costs $48. Members pay $0.99 per song to download music. Nonmembers may download songs for $1.29 each.
Answer:
160 musics
Step-by-step explanation:
let the total amount/charges be y
let the number of musics be x
For members total
y=48+0.99x-------1
For non-members total
y=1.29x-------------2
we are expected to solve for the number of music where members and non members get to pay the same amount
equating 1 and 2 we have
48+0.99x=1.29x
48=1.29x-0.99x
48= 0.3x
x=48/0.3
x=160 musics
