The values of the zero are 1 and 3 if the quadratic function is m(x) = x² - 4x + 3 after solving algebraically.
What is a quadratic equation ?Any equation of the form [tex]\rm ax^2+bx+c=0[/tex] where x is variable and a, b, and c are any real numbers where a ≠ 0 is called a quadratic equation.
As we know, the formula for the roots of the quadratic equation is given by:
[tex]\rm x = \dfrac{-b \pm\sqrt{b^2-4ac}}{2a}[/tex]
We have quadratic function:
m(x) = x² -4x + 3
m(x) = x² -x - 3x + 3
m(x) = x(x -1) -3(x - 1)
m(x) = (x - 1)(x - 3)
x -1 = 0 or x -3 = 0
x = 1 or x = 3
Thus, the values of the zero are 1 and 3 if the quadratic function is m(x) = x² - 4x + 3 after solving algebraically.

The zeros of the quadratic function m(x) = x² - 4x + 3 are found using the quadratic formula, yielding two solutions, x = 1 and x = 3.
To find the zeros of the quadratic function m(x) = x² - 4x + 3, we first note that it is already in standard form, with a = 1, b = -4, and c = 3. The quadratic formula, which states if ax² + bx + c = 0, then x = (-b ± √(b² - 4ac)) / (2a), can be used to find the solutions. Substituting the values, we get:
x = (4 ± √((-4)² - 4(1)(3))) / 2(1)
x = (4 ± √(16 - 12)) / 2
x = (4 ± √4) / 2
x = (4 ± 2) / 2
This results in two solutions:
x = (4 + 2) / 2 = 6 / 2 = 3
x = (4 - 2) / 2 = 2 / 2 = 1
Therefore, the zeros of the function m(x) are 1 and 3.

In order to solve the following system of equations by subtraction, which of
the following could you do before subtracting the equations so that one
variable will be eliminated when you subtract them?
4x – 2y = 7
3x – 3y=15
A. Multiply the top equation by 1/3
B. Multiply the top equation by 3 and the bottom equation by 4.
C. Multiply the top equation by-3 and the bottom equation by 2.
D. Multiply the top equation by 15 and the bottom equation by 7.
Answer:
B
Step-by-step explanation:
B produces the term 12x that cancels out after subtraction.
In order to eliminate one variable by subtracting, you should multiply the top equation by -3 and the bottom equation by 2. In doing so, this will make the coefficients of y equal and opposite, allowing this variable to be eliminated when the two equations are added together.
Explanation:The question relates to the method of solving a system of linear equations by subtraction. In order to eliminate one variable when subtracting these equations, we would need to manipulate the equations such that the coefficients of one variable are exact opposites. Hence, the objective is to make the coefficients of y, -2 and -3, opposite each other.
To achieve this, the correct answer is C. Multiply the top equation by -3 and the bottom equation by 2.
By performing these multiplications we'll have:
-12x + 6y = -21.
6x - 6y = 30.
Now, if we add these two equations, we'll be able to eliminate the y variable and can proceed to solve for x.

Find, to the nearest degree, the angle of elevation of the sun when a person 170 cm tall casts of shadow 220 cm long.
Trigonometry
Answer:
Θ = 52°
Step-by-step explanation:
Once you've set up the triangle, you can see that the adjacent side is 170 cm and the opposite side is 220 cm.
tanΘ = [tex]\frac{220}{170}[/tex]
Θ = tan-1 (220/170)
Θ = 52°
The angle of elevation of the sun when a person 170 cm tall casts of shadow 220 cm long is 37.694°.
What is trigonometry?Trigonometry deals with the relationship between the sides and angles of a right-angle triangle.
A person 170 cm tall casts of shadow 220 cm long.
Then the angle will be
[tex]\rm tan \theta = \dfrac{Perpendicular }{Base}[/tex]
We have
Perpendicular = 170 cm
Base = 220 cm
Then
[tex]\rm tan \theta = \dfrac{170}{220}\\\\\\ \theta \ \ \ \ = tan^{-1} \dfrac{170}{220}\\\\\\\theta \ \ \ \ = 37.694^o[/tex]

The wholesale price for a pair of shoes is $8.50. A certain department store marks up the wholesale price by 90%. Find the price of the pair of shoes in the department store. Round your answer to the nearest cent, as necessary.
Answer:
$16.15
Step-by-step explanation:
The wholesale price:
$8.50Selling Price:
$8.50 + 90% = $8.50 *1.9 = $16.15Pair of shoes sold for $16.15 in the store
The department store marks up the wholesale price by 90%, equating to $7.65. Adding this to the original wholesale price of $8.50, the retail price of the shoes in the department store is $16.15.
Explanation:To calculate the retail price of the shoes in the department store, we need to add the markup value to the original wholesale price. The markup is 90% of the wholesale price. Therefore, we calculate 90% of $8.50, and then add that to the original price.
To find 90% of $8.50, we multiply $8.50 by 90/100. This gives us $7.65. This is the markup value.
We then add this markup value to the original wholesale price. So, $8.50 + $7.65 = $16.15.
The price of the pair of shoes in the department store is therefore $16.15.

Write the equation of the given line in
slope- intercept form
Answer:
y=2x+3
Step-by-step explanation:
Answer:
y = -3x - 1
Step-by-step explanation:
Point Slope Form: (y - y1) = m(x - x1)
Step 1: Find the slope using [tex]\frac{y2 - y1}{x2 - x1}[/tex]
(x1, y1) = (-1, 2)
(x2, y2) = (1, -4)
m = [tex]\frac{-4 - 2}{1 -(-1)}[/tex]
m = [tex]\frac{-6}{1+1}[/tex]
m = [tex]\frac{-6}{2}[/tex]
m = -3
Step 2: Plug into point slope form and solve for y
(y - y1) = m(x - x1)
(y - 2) = -3(x - (-1))
y - 2 = -3(x + 1)
y - 2 + 2 = -3x - 3 + 2
y = -3x - 1
Answer: y = -3x - 1
2. A boy who is 5 feet 6 inches tall casts a shadow that is 8 feet and 3 inches long. What is the measure of the
angle of elevation of the sun, A, as shown in the picture. Round to the nearest degree. Be careful with your
units in this problem.
Answer:
34°
Step-by-step explanation:
The boy is 5 feet 6 inches tall.
The boy casts a shadow that is 8 feet and 3 inches long.
We know 12 inches equal 1 foot.
Therefore the boy's height is 5.5ft and the shadow is 8.25ft.
The angle of elevation of the sun is given by the tangent of the angle A.
[tex] \tan(A) = \frac{5.5}{8.25} [/tex]
[tex]\tan(A) = 0.6667[/tex]
[tex]A= {\tan}^{ - 1} (0.6667)[/tex]
[tex]A=33.69 \degree[/tex]
To nearest degree is 34°
Answer: 34 degrees
Step-by-step explanation:
the boy is 5’6
5x12=60+6=66
The shadow is 8’3
8x12=96+3=99
You would use tan(X)= 5.5/8.25

What is the length of the hypotenuse?
Answer:
Hi there!
The correct answer will be 15 yd
Step-by-step explanation:
There are two ways you can go about solving this problem
Method One: Pythagorean Theorem
a^2 + b^2 = c^2 then all you have to do is plug in the values
(12)^2 + (9)^2 = c^2 you should get c^2 = 225 then you square root both sides and you get c = 15
Method Two: Pythagorean Identities
This triangle represents a 3,4,5 triangle
All the sides just tripled so that means the hypotenuse is 5*3 which equals 15
An art supply store typically sells bottles of green paint for every 9 bottles of aqua paint. How many bottles of aqua paint does it sell when it sells 30 bottles of green paint?
Final answer:
The store sells 270 bottles of aqua paint when it sells 30 bottles of green paint.
Explanation:
To find out how many bottles of aqua paint the store sells when it sells 30 bottles of green paint, we can set up a proportion. Since the store sells 9 bottles of aqua paint for every 1 bottle of green paint, we have the ratio 9/1. We can set this equal to the unknown quantity, x, over 30 (the number of green paint bottles).
9/1 = x/30
Next, cross multiply to solve for x. Cross multiplying gives us:
9 * 30 = 1 * x
Simplifying this equation gives us:
270 = x
Therefore, the store sells 270 bottles of aqua paint when it sells 30 bottles of green paint.

angle?
a. 145.40
c. 55.4°
b. 34.6°
d. 90°
Solution:
Given that,
One of the acute angles in a right triangle has a measure of 34.6°
The sum of the three angles of a triangle is always 180 degrees.
Also, that the measure of a right angle is always 90 degrees
Let "x" be the other acute angle
Therefore,
x + 90 + 34.6 = 180
x + 124.6 = 180
x = 180 - 124.6
x = 55.4
Thus the measure of other acute angle is 55.4 degrees
Answer:
Yes, what the other person said
Step-by-step explanation: basically you subtract 90.0 - 34.6
i need help finding the area of a figure where the rectnagles area is 5 x 14 and the half circles diameter is 6
Answer:
84.14 square units, total
