here is an example for my class, these really helped

A quadratic equation is any second-degree polynomial equation — that’s when the highest power of x, or whatever other variable is used, is 2. The solution or solutions of a quadratic equation,

Solve the equation,

with the quadratic formula:

Bring all terms to one side of the equation, leaviign

Plug the coefficients into the formula.

In this example, a equals 2, b is –5, and c is –12, so

You can also use the quadratic formula for factoring trinomials.

Here’s what you do.

Use the quadratic formula to get solutions for x. (You can also use your calculator to get the solutions.) Make sure the solutions are written as fractions rather than as decimals and that they’re reduced to lowest terms.

Take the two solutions and put them in factors. If a solution is positive, use subtraction. If a solution is negative, use addition.

If either solution is a fraction, take the denominator and bring it in front of the x.

And, voilà, the trinomial is factored:

(x – 4)(2x + 3)

Answer:

X= -1

Step-by-step explanation:

how u can see I apply the formula, and I have two answers X1= -1 and X2= -1

U only need to see the information that they give u, it was x^2+2x+1=0

and we know that

a= 1

b=2

c=1

then you replace in the formula and do the exercise:)

Answer:

x+4

Step-by-step explanation:

Equation for the situation will be y = x + 4.

   Given in the question,

  "A car wash company charges $4 initial fee plus $1 for each car wash"

Let the number of car washes = x

Cost of 'x' car washes = $x

Total fee (with initial fee) for 'x' car washes = $(x + 4)

  Therefore, equation for the total amount 'y' will be,

y = x + 4

Answer:

x<2.5

Step-by-step explanation:

-4x +5>-5

-4x>-5-5

-4x>-10

x<10/4(on multiplying (-)ve sign both the sides inequality changes)

x < 2.5

The inequality -4x + 5 > -5 simplifies to x < 2.5 after isolating the variable and dividing by -4, which also reverses the inequality sign.

To solve the inequality -4x + 5 > -5, we first isolate the variable on one side:

Let's solve the inequality step-by-step:

Therefore, the solution to the inequality is x < 2.5.

Answer: The solution for y would be y = -7

Step-by-step explanation:

-Solve:

[tex]3y+4y=-49[/tex]

-First, Combine like terms:

[tex]3y+4y=-49[/tex]

[tex]7y=-49[/tex]

-Then, divide both sides by 7:

[tex]7y= -49[/tex]

[tex]\frac{7y}{7} = \frac{-49}{7}[/tex]

[tex]y=-7[/tex]

So, therefore the result would be y= -7.

Answer:

correct option is 2187

Total surface area is  2,185.44  square inches.

lateral surface area is  640.56 square inches

Step-by-step explanation:

Given

radius of cylinder = 12 inches

height of cylinder = 17 inches

we will us value of pi as 3.14

surface area for cylinder consist of two part

1. lateral surface area which is gven by [tex]2\pi rl[/tex]

where r is radius of cylinder and l is height of cylinder

Thus, lateral surface area for given cylinder is

[tex]2\pi rl\\ =>2* 3.14*12*17\\=> 1281.12[/tex]

Thus,  lateral surface area for given cylinder is  1281.12 square inches.

_________________________________

second part of surface area is area of two base (upper and lower) of cylinder.

area of base is given by area of circle [tex]\pi r^2[/tex]

[tex]area \ of \base = \pi r^2 = 3.14*12^2\\=>area \ of \base = 3.14*144 = 452.16[/tex]

This, area of base is for one base of cylinder

since there are 2 base

area of both base will be = 2* area of one base

                                      = 2*452.16 = 904.32.

Thus, area of base is 904.32 sq. in.

_______________________________________

Total surface area of cylinder = area of two base+ lateral surface area of cylinder = 1281.12 square inches + 904.32 square inches

                  = 2,185.44  square inches.

Thus, total surface area is  2,185.44  square inches.

lateral surface area is  640.56 square inches

but option which is closest to calculated value is  2187.

Thus, correct option is 2187

___________________________________________

Note: this problem can be directly solved using formula

total surface area for cylinder = [tex]2\pi r^2 + 2\pi rl[/tex]

La respuesta es la C

Step-by-step explanation:

Primero tienes que hacer el 25% de ambas cantidades y luego sumarlo

The required, tax would be $25,750 if the Tanners file jointly.

The percentage is the ratio of the composition of matter to the overall composition of matter multiplied by 100.

Here,

Assuming that the tax rate of 25% applies to their combined taxable income, here's how to calculate their taxes if they filed jointly:

Calculate their combined taxable income:
$75,000 + $28,000 = $103,000

Calculate their tax liability based on their combined taxable income: $103,000 x 0.25 = $25,750

Therefore, the answer is C. $25,750, if the Tanners file jointly.

Answer: The correct answer is option C; 90√2

Step-by-step explanation: The line segments are labelled as base 1, base 2 and base 3 respectively. This we shall call point 1, point 2 and point 3. These three points form a right angle. Also we have been told that Marcus is on point 3 and Jean is on point 2. They are both 90 feet apart. Also Joel is on point 1 and he is 90 feet away from Jean. The unmeasured distance therefore is from point 1 to point 3, which is the distance from Joel to Marcus (or Marcus to Joel).

The distance from point 1 to point 3 is the hypotenuse of the right angled triangle derived. Using the Pythagoras' theorem, the distance from  Joel to Marcus (or JM) is calculated as follows;

JM² = JC² + JL²

Where JM is the distance between Joel and Marcus (hypotenuse), JC is the distance from Jean to Marcus and JL is the distance from Jean to Joel.

JM² = 90² + 90²

JM² = 8100 + 8100

JM² = 16200

Add the square root sign to both sides of the equation

√JM = √16200

JM = √100*√81*√2

The right hand side of the equation can be further solved as

JM = 10*9*√2

JM = 90√2

Therefore the distance between Marcus and Joel is calculated as 90√2 feet

NAFTA as an organization is  very important for the three North American economies, the USA, Canada, and Mexico. It is basically a regional trade organization which has lifted the borders when it comes to trade, thus enabling free movement of goods between these three nations. This has resulted in rise of the economies of all three nations, as there were no trade barriers between them anymore. The companies where able to move their facilities and to operate in each of these countries, which brought them larger profits. The Canadian and the US economies became almost like one, as the companies managed to operate in both places, and to become major players in the market, this especially goes for the US companies that made Canada their home terrain.

Answer:

NAFTA eliminates almost all barriers to trade and investment between the three North American countries and includes provisions for the protection of intellectual property rights.

Answer: 1 ft3

Step-by-step explanation:

Hi, to answer this question, first we have to calculate the volume of the rectangular plate:

Volume of a rectangular prism: width x length x height (thickness)

Replacing with the values given:

V = 1 x 1.5 x 3/4= 1.125 ft3

Now, we have to calculate the volume of the hole:

Volume of a cylinder = π (diameter/2)^2 x height( thickness of the plate)

V = π (1/2)^2 (3/4) = 0.59 ft3

Finally, we have to subtract the volume of the hole to the volume of the plate:

1.125-0.1875 =0.53 ft3 = 1 ft3 (rounded)
