The solution to the quadratic equation is x = 2 ± √3

What is Quadratic Equation?

A quadratic equation is a second-order polynomial equation in a single variable x , ax² + bx + c=0. with a ≠ 0. Because it is a second-order polynomial equation, the fundamental theorem of algebra guarantees that it has at least one solution. The solution may be real or complex.

The roots of the quadratic equations are

x = [ -b ± √ ( b² - 4ac ) ] / ( 2a )

where ( b² - 4ac ) is the discriminant

when ( b² - 4ac ) is positive, we get two real solutions

when discriminant is zero we get just one real solution (both answers are the same)

when discriminant is negative we get a pair of complex solutions

Given data ,

Let the quadratic equation be represented as A

Now , the value of A is

x² + 4x + 1 = 0   be equation (1)

And , roots of the quadratic equations are

x = [ -b ± √ ( b² - 4ac ) ] / ( 2a )

On simplifying , we get

x = [ -4 ± √ ( 4 )² - ( 4 ) ( 1 ) ( 1 ) ] / 2

x = [ -4 ± √ ( 16 - 4 ) ] / 2

x = [ -4 ± √12 ] /2

On further simplification , we get

x = [ -4 ± 2√3 ] /2

x = 2 ± √3

Therefore , the value of x is 2 + √3 or 2 - √3

Hence , the roots of the quadratic equations is x = 2 ± √3

Your town decides to build a volleyball court. If the court is approximately 40 by 70 feet and its surface is of sand, 1 foot deep, the court will require about 166 tons of sand. A local sand pit sells sand for $11 per ton with a delivery charge of 3 dollars per ton. Write and solve an equation to find the total cost of the sand for this court.

Answers

Since they give you the needed tons of sand you dont need the dimensions anymore. So the equation for the cost would be y=(11+3)x where y is the total cost, x is the amount of sand needed and 11+3 is the cost of one ton of sand + the deliverly charge per ton

A function assigns the value of each element of one set to the other specific element of another set. The total cost of the sand for this court is $2,324.

What is a Function?

A function assigns the value of each element of one set to the other specific element of another set.

The function for the total cost can be written as in the form as shown below,

Total cost = Cost of sand + Cost of delivery

The total cost for x tons of sand can be written as,

Total cost(x) = $11(x) + $3(x)

Since the volleyball court needs 166 tons of sand, therefore, the total cost for 166 tons of sand can be written as,

Total cost(x) = $11(x) + $3(x)

Total cost(166) = $11(166) + $3(166)

Total cost = $1826 + $498

Total cost = $2,324

Hence, the total cost of the sand for this court is $2,324.

The graph of y=x^2 is reflected in the x-axis and translated 3 units right and 2 units up. Write an equation for the function in vertex form and in standard form.

Answers

y= (x-3)^2 +2 I hope I helped :)

The equations for the transformed function in vertex form and in standard form are as follows: Vertex form: [tex]\( y = -(x - 3)^2 + 2 \)[/tex], Standard form: [tex]\( y = -x^2 + 6x - 7 \)[/tex]

To arrive at these equations, let's go through the transformation steps:

1. The original function is [tex]\( y = x^2 \)[/tex].

2. Reflecting the graph in the x-axis changes the sign of the function, resulting in [tex]\( y = -x^2 \)[/tex].

3. Translating the graph 3 units right means replacing [tex]\( x \)[/tex] with [tex]\( x - 3 \)[/tex], giving us [tex]\( y = -(x - 3)^2 \)[/tex].

4. Finally, translating the graph 2 units up means adding 2 to the function, yielding the vertex form [tex]\( y = -(x - 3)^2 + 2 \)[/tex].

To convert this vertex form into standard form, we expand the vertex form and simplify:

[tex]\( y = -(x - 3)^2 + 2 \)\\ \( y = -(x^2 - 6x + 9) + 2 \)\\ \( y = -x^2 + 6x - 9 + 2 \)\\ \( y = -x^2 + 6x - 7 \)[/tex]

This is the standard form of the transformed quadratic function.

The Holiday Rush gets really intense. You work from 7am to 11pm on the Friday and Saturday just before Xmas, selling clothes and then stocking shelves, and then from 9am to 9pm on Sunday. Your pay rate is $20 per hour. How much do you get in gross wages for that one weekend

Answers

Weekend just includes Saturdays and Sundays, so you don't have to count the earnings on Friday. You simply have to count the number of hours that passed from 7 am to 11 pm on Saturday. That would be a total of 16 hours. While on Sunday, the time from 9 am to 9 pm is a total of 12 hours. Hence, the total time would be 16 hours + 12 hours = 28 hours

Gross Wage = $20(28 hours) = $560

The total hours worked over the weekend are 44 hours, resulting in gross wages of $880.

To calculate the gross wages for the weekend, we need to multiply the hours worked each day by the hourly pay rate of $20. On Friday and Saturday, the working hours are from 7am to 11pm, which is 16 hours each day. On Sunday, the working hours are from 9am to 9pm, which is 12 hours.

To find the total hours worked over the weekend, we add the hours for each day:

Friday: 16 hoursSaturday: 16 hoursSunday: 12 hours

Now we calculate the total hours: 16 + 16 + 12 = 44 hours.

Next, we calculate the total earnings by multiplying the total hours by the hourly rate:

= 44 hours x $20 per hour = $880.

Therefore, the gross wages for the weekend work are $880.

a 20 ft piece of string is cut into two pieces so that the longer piece is 5 feet longer than twice the shorter piece. If the shorter piece is x feet long, find the lengths of both pieces

Answers

Answer:

The shorter piece is 5 ft long.

The longer piece is 15 ft long.

Step-by-step explanation:

Let's write this into an equation:

(5+2x)+x=20

5+3x=20

Subtract 5 from both sides

3x=15

x=5

The shorter piece is 5 ft long.

The longer piece is 5 feet longer than 2 times 5 ft (the shorter piece).

5+2*5

5+10

15

The longer piece is 15 feet long.

Mei bought a box of markers for b dollars, a shoulder bag that cost twice as much as the box of markers and a pen that cost $6 less than the shoulder bag. Write the cost of the pen in terms of b.

Answers

Final answer:

The cost of the pen in terms of b is (2b - 6) dollars.

Explanation:

To write the cost of the pen in terms of b, we need to determine the cost of the pen relative to the cost of the markers.

Let's assign a variable to the cost of the shoulder bag. Since the shoulder bag costs twice as much as the box of markers, we can write the cost of the shoulder bag as 2b dollars.

Now, the pen costs $6 less than the shoulder bag, so the cost of the pen can be written as (2b - 6) dollars. Therefore, the cost of the pen in terms of b is (2b - 6) dollars.

To use the distributive property, you take the number outside of the parenthesis and multiply it by everything inside.

To begin, we take -3 and multiply it by n.

Now, we multiply -3 by -4. (We are multiplying by -4 and not +4 since there is a minus sign in front of the four.)

-3 * -4 = 12

Find a combination of 3 numbers that equal 34 and write the equation

Answers

23×+11
is the equation

Final answer:

To form an equation with a sum of 34 using three numbers, one possible combination is 10, 12, and 12, resulting in the equation 10 + 12 + 12 = 34.

Explanation:

To find a combination of 3 numbers that equal 34, we can use simple addition. For example, let's choose three numbers such as 10, 12, and 12. Adding these together, we get the equation 10 + 12 + 12 = 34. This is just one of many possible combinations that satisfy the condition.

If we wanted a methodical approach to find different combinations, we could start with the first number and systematically increase it while decreasing one of the other numbers. It's important to test different combinations and remember that you can also use the same number more than once as we did with the number 12.

Remember, an equation must have an equal sign, while an expression is just a group of numbers and operations. In this case, we are looking for an equation since we want to show that the sum of the three numbers we pick is equal to 34.

The height of the box will be 5 inches considering the ribbon is wrapping over the perimeter along the height.

What is the perimeter?

Perimeter is the addition of an external measure of sides it will always positive.

A perimeter is a length and has a degree of the unit as one.

For example

Perimeter of square = side + side + side + side

The perimeter of the circle = πd where d is the dia of the circle.

The total length of the ribbon = is 70 inches.

The bow takes 32 inches of ribbon.

So left = 70 - 32 = 38 inches.

Now,

38 inches = Perimeter along the height

2 ( L + 14 ) = 38

L + 14 = 19

L = 5 inches.
