The answer is:
b. [tex]g(x)=x^{2} +3[/tex]
Why?To find what's the equation of the red graph, first, we need to find a function that intercepts the y-axis at 3 and its vertex is located at (0,3)
We must remember that the constant value in a quadratic equation (c) will tell us where the function intercepts the y-axis, so, we are looking for an equation which has a constant value equal to 3, it discards the options a, c and d, so the correct option would be the option b.
Option b function:
[tex]g(x)=x^{2} +3[/tex]
Where,
[tex]a=1\\b=0\\c=3[/tex]
Let's check if the option b is the correct option:
First, let's find the axis intercepts:
Y-axis intercept
[tex]f(x)=x^{2}+3\\f(0)=0^{2}+3\\y=3[/tex]
X-axis intercept
[tex]0=x^{2}+3\\x=\sqrt{-3}[/tex]
There is no x-axis intercepts since the square roots of negative numbers does not exists in the real numbers.
Finding the vertex coordinates:
The x coordinate of the vertex can be found using the following equation:
[tex]x=-\frac{b}{2a}=-\frac{0}{2*1}=0[/tex]
The x coordinate of the vertex is located at x=0, so to find the y-coordinate we must substitute the x value into the parabola equation, so
[tex]y=x^{2}+3=0^{2}+3=3[/tex]
So, the y coordinate of the vertex is located at y=3
Therefore, the vertex of the function is (0,3)
Hence, the calculated values of the option b match with the given graph.
The correct option is: b. [tex]g(x)=x^{2} +3[/tex]

The rectangle shown has an area of 27 cm2 and is modeled by the equation A = 2w2 + 3w, where w is the width. What is the length of the rectangle?
Answer:
The length of the rectangle is [tex]9\ cm[/tex]
Step-by-step explanation:
we know that
The area of rectangle is equal to
[tex]A=LW[/tex]
In this problem we have
[tex]A=27\ cm^{2}[/tex]
so
[tex]27=LW[/tex] ------> equation A

so
[tex]27=2w^{2}+3w[/tex]
[tex]2w^{2}+3w-27=0[/tex]
The formula to solve a quadratic equation of the form [tex]ax^{2} +bx+c=0[/tex] is equal to
[tex]x=\frac{-b(+/-)\sqrt{b^{2}-4ac}} {2a}[/tex]
in this problem we have
[tex]2w^{2}+3w-27=0[/tex]
so
[tex]a=2\\b=3\\c=-27[/tex]
substitute in the formula
[tex]w=\frac{-3(+/-)\sqrt{3^{2}-4(2)(-27)}} {2(2)}[/tex]
[tex]w=\frac{-3(+/-)\sqrt{225}} {4}[/tex]
[tex]w=\frac{-3(+/-)15} {4}[/tex]
[tex]w=\frac{-3(+)15} {4}=3[/tex]
[tex]w=\frac{-3(-)15} {4}=-4.5[/tex]
The solution of the quadratic equation is
[tex]w= 3\ cm[/tex]
Find the value of L
[tex]27=L(3)[/tex]
[tex]L=27/3=9\ cm[/tex]

Answer:
x=3
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
2(2x−17)+4=−3(3+x)
4x+−34+4=−9+−3x {distribute}
4x+−30=−3x−9 {combine like terms}
Step 2: Add 3x to both sides.
4x−30+3x=−3x−9+3x
7x−30=−9
Step 3: Add 30 to both sides.
7x−30+30=−9+30
7x=21
Step 4: Divide both sides by 7.
7x/7=21/7
x=3
4x - 3x = -9 + 30 2 (2x - 17) + 4 = -3 (3 + x)
So, we are going to DISTRIBUTE
Lets work on the left side of the equation first
Multiply 2 on the out side of the parenthesis by what is on the inside
2 x 2x = 4x
2 x -17 = -34
So on the left side we now have
4x - 34 + 4
add 4
4x - 30
Let's do the same thing on the other side
-3 x 3 = -9
-3 x X = 3x
Now let's put everything together
4x - 30 = -9 + 3x
COMBINE LIKE TERMS
x = 21

Which will equation show correctly we write an expression that represents the cost for a pair of shoes that is marked down 20% of the regular price when the sales tax is 5% of the markdown price?
Answer:
A
Step-by-step explanation:
You can write an expression to represent the total cost of a pair of shoes. The price of the shoes is the variable r. The shoes are marked down 20% or 0.2r. So the new price of the shoes will be r - 0.2r. You will also have to pay a tax of 5% or 0.05 of the new price. This is written as 1.05(r - 0.2r). You can simplify it by doing whats in the parenthesis.
1.05(r - 0.2r) = 1.05r(0.8r) = 0.84r

describe the nature of the roots for this equation.
3x^2 - 2x + 1 = 0
A. two real, rational roots
B. two real, irrational roots
C. one real, double root
D. two complex roots
Answer:
Option D. two complex roots
Step-by-step explanation:
we know that
In a quadratic equation of the form [tex]ax^{2} +bx+c=0[/tex] the discriminant D is equal to
[tex]D=(b^{2}-4ac)[/tex]
in this problem we have
[tex]3x^{2} -2x+1=0[/tex]
so
[tex]a=3\\b=-2\\c=1[/tex]
substitute the values
[tex]D=(-2^{2}-4(3)(1))[/tex]
[tex]D=(4-12)[/tex]
[tex]D=-8[/tex]
The discriminant is negative
therefore
The quadratic equation has two complex roots
Final answer:
The equation 3x² - 2x + 1 = 0 has a negative discriminant of -8, indicating that it does not have real roots but instead has two complex roots.Therefore, the correct answer is D. two complex roots.
Explanation:
To determine the nature of the roots for the equation 3x²- 2x + 1 = 0, we need to calculate the discriminant, which is given by b² - 4ac. Here, a = 3, b = -2, and c = 1. Substituting these values into the discriminant formula gives us (-2)² - 4(3)(1) = 4 - 12 = -8. Since the discriminant is negative, the equation does not have real roots. Instead, it has two complex roots.
Therefore, the correct answer is D. two complex roots.

Write an equation for the circle with a center of (5, -2) and a radius of 3.
Answer:
(x - 5)² + (y + 2)² = 9
Step-by-step explanation:
The equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k) are the coordinates of the centre and r is the radius
here (h, k) = (5, - 2) and r = 3, thus
(x - 5)² + (y - (- 2))² = 3², that is
(x - 5)² + (y + 2)² = 9 ← equation of circle

Adrell has four suit jackets (white, blue, green, and tan) and four dress shirts in the same colors. How many different jackets/shirt outfits does Adrell have?
A. How many jacket/shirt outfits does Adrell have?
B. Suppose he grabs a suit jacket and a dress shirt without looking. What is the probability that they will not be the same color?
Answer:
A=4, B=3/4
Step-by-step explanation:
it says that she has four suit jackets, and since there are 16 possibilities(4 x 4)
and 4 of them have the same colors, we do 16-4/16, which is 12/16, and we simplify that to 3/4
Final answer:
Adrell has 16 different jacket/shirt outfits and there is a 75% probability that the jacket and shirt will not be the same color.
Explanation:
Adrell has four suit jackets (white, blue, green, and tan) and four dress shirts in the same colors. To find the number of different jacket/shirt outfits, we multiply the number of options for the jacket by the number of options for the shirt. Since there are 4 options for the jacket and 4 options for the shirt, there are a total of 16 different jacket/shirt outfits.
If Adrell grabs a suit jacket and a dress shirt without looking, the probability that they will not be the same color can be found by calculating the number of favorable outcomes (jacket and shirt of different colors) divided by the total number of possible outcomes. Since there are 4 jackets and 4 shirts, the total number of possible outcomes is 4 * 4 = 16. The number of favorable outcomes is when the jacket and shirt are of different colors, which is 4 * 3 = 12. Therefore, the probability that the jacket and shirt will not be the same color is 12/16 = 3/4 or 75%.
