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.PLEASE help me with this equation

This diagram of a rectangular city park was drawn using a scale of 1 centimeter to 20 meters
(In the diagram shown, assume each square on the grid is 1 centimeter in length.)
What is the area, in square meters, of the actual park?
What is the scale factor?
Answer:
Scale factor for the drawing from actual park = [tex]\frac{1}{20}[/tex]
Area of the actual park = 1200 cm²
Step-by-step explanation:
Length of the rectangular city park = 5 cm
Width of the rectangular park = 6 cm
Using scale factor 1 cm = 20 meters
Scale factor = [tex]\frac{\text{length of the park in drawing}}{\text{Actual length of park}}=\frac{1}{20}[/tex]
[tex]\frac{5}{\text{Actual length of park}}=\frac{1}{20}[/tex]
Actual length = 5 × 20 = 100 meters
Actual width = 6 × 20 = 120 meters
Area of the rectangular park = length × width
= 100 × 120
= 1200 square meters
Therefore, Scale factor from actual length to the length in drawing = 1 : 20
Area of the rectangular park = 1200 square feet

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
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.

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%

Lea's school is selling tickets to the annual talent show. On the first day of ticket sales the school sold 12 adult tickets and 7 child tickets for a total of $236. The school took in $217 on the second day by selling 7 adult tickets and 14 child tickets. What is the price each of one adult ticket and one child ticket?
Answer:
Step-by-step explanation:
let the number of children be x
and the number of adults be y
so
7x+12y=236-----1
and
14x+7y=217------2
equating both 1 and 2 we have
7x+12y=236-----1
14x+7y=217------2
multiply 1 by 2
subtract 2 from 1 we have
14x+24y=472-----3
- 14x+7y=217------2
0x+17y=255
17y=255
y=255/17
y=15
put y=15 in eqn 1 we have
7x+12y=236-----1
7x+12*15=236-----1
7x+180=236-----1
7x=236-180
7x=236-180
x=56/7
x=8
therefore a child will cost $8 and adult will cost $15

2. In right triangle RST with right angle S the m4R = 24°. What is the
measure of T?*
о
24°
O 56°
0 66°
O 116°
Sum of the interior angles of any triangle equal 180° ;
So :
90° + 24° + T = 180°
114° + T = 180°
subtract both sides 114
T = 180° - 114°
T = 66°
