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.evaluate each expression 5(10-1)

When f(c)= 10x^2 + 3x -4, evaluate f(-4)
Answer:
[tex]f(x) = 144[/tex]
Step-by-step explanation:
This problem deals with a function. All this question is asking is to plug in -4 every time an x appears.
So, let's do that:
[tex]f(-4) = 10(-4)^{2} + 3(-4) - 4[/tex]
[tex]f(-4) = 10(16) - 12 - 4[/tex]
[tex]f(-4) = 160 - 16[/tex]
[tex]f(-4) = 144[/tex]

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
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%
Andre ran 2 kilometers in 15 minutes, and Jada ran 3 kilometers in 20 minutes.
Both ran at a constant speed.
Did they run at the same rate? Explain or show your reasoning.
I
They did not run at the same rate because
Answer:
They do not run at the same rate because Jada ran at a rate of .150km per min, while Andre ran at .133333 km per minute.
Step-by-step explanation:
Andre ran : 2km/15min = .133333km per min
Jada ran: 3km/20min=.150km per minute
.150>.1333, so Jada ran at a higher rate of kilometers per minute.

You are decorating a Rose Bowl float. There are 108 red roses, 144 white roses, 48 yellow roses, and 72 purple roses. If bunches of roses are identical and there are no leftover roses, what is the greatest number of bunches that can be made? How many roses of each color are in each bunch?
Answer:
Step-by-step explanation:
Number of red roses = 108
Number of white roses = 144
Number of yellow roses = 48
Number of purple roses = 72
If the number of roses in each bunch are identical,
Number of bunches of roses = HCF of number of roses
Factors of 144 = 3×3×2×2×2×2×1
Factors of 108 = 3×3×3×2×2×1
Factors of 72 = 3×3×2×2×2×1
Factors of 48 = 3×2×2×2×2×1
Common factors of 144, 108, 72, 48 = 3 × 2 × 2 × 1 = 12
Therefore, number of bunches of roses with equal number of roses = 12
Number of red roses in each bunch = [tex]\frac{108}{12}=9[/tex]
Number of white roses in each bunch = [tex]\frac{144}{12}=16[/tex]
Number of yellow roses in each bunch = [tex]\frac{48}{12}=4[/tex]
Number of purple roses in each bunch = [tex]\frac{72}{12}=6[/tex]
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

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.

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°
