A quadratic equation has the generic form ax2 + bx + c = 0. Thus, the roots are hypothetical, meaning that they have two false roots.

The equation's nature of roots indicates whether it contains rational, irrational, or fictitious roots. Imaginary roots and unreal roots are synonyms.

Having just second-order terms, the quadratic form is a unique nonlinear function (either the square of a variable or the product of two variables).

2x2 - 3x + 5 = 0

a = 2 , b = -3, c = 5

b2 - 4ac = (- 3)2 - 4 (2) (5) (5)

= 9 - 40

= - 31

b2 - 4ac < 0

Therefore, the equation lacks any true roots.

A circle is formed when every point in the plane that is a specific distance apart from another point does so (center). Thus, it is a curve made up of points that are separated from one another by a set distance while moving in the plane. It is also rotationally symmetric about the center at all angles. A circle is a closed, two-dimensional object where each pair of points in the plane is equally separated from the "center." A specular symmetry line is made by drawing a line through the circle. It is also rotationally symmetric about the center at all angles.

The simplified exponential expression 3^10×37^9/9^12 as a single power of 3 is given as follows:

3^70.

The exponential expression for this problem is defined as follows:

[tex]\frac{3^{10} \times (3^7)^{12}}{9^{12}}[/tex]

Applying the power of power rule, we have that:

(3^7)^12 = 3^(7 x 12) = 84.

When two terms with the same base and different exponents are multiplied, we keep the base and add the exponents, hence:

3^10 x 3^84 = 3^94.

For the denominator, we have that:

9^12 = (3²)^12 = 3^24.

When two terms with the same base and different exponents are divided, we keep the base and subtracted the exponents, hence:

3^94/3^24 = 3^(94 - 24) = 3^70.

Answer:

$488.33 monthly savings

Step-by-step explanation:

Parent payment 30% of $21,800 is $6,540.

Subtract all payment from total cost.

Substitution is a method for solving systems of equations by substituting the values from one equation into the other. To use substitution to determine if an ordered pair is the solution to a system of equations, first solve one of the equations for either x or y.

Then substitute this value into the other equation, and solve for the other variable. If the ordered pair you obtain is also found in both equations, then it is a solution to the system.

Take the equation set as an example.

2x + y = 5

3x – y = 1

To use substitution to determine if (2, 3) is a solution to this system, first solve one of the equations for either x or y:

2x + y = 5  ⇒ y = 5 – 2x

Add this value to the other equation after that:

3x – (5 – 2x) = 1  

⇒  5x = 6  

⇒ x = 6/5

Finally, substitute 6/5 back into either equation to find y:

2(6/5) + y = 5  

⇒ 12/5 + y = 5  

⇒  y = 10/5  

⇒  y = 2

Since (6/5, 2) is found in both equations, it is a solution to the system.

32.56 is the expected weight for a bluegill fish that is 11 inches long.

Equation: What is it?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" symbol and terms on both sides must always be present when writing an equation. Equal treatment should be given to each party. Multiple terms, operators, and variables are not required on each side of an equation. Without them, one can still create an equation, such as 5 + 10 = 15. There are no variables in the equation below.

given expression:

In(Weight) = -5.28 + 3.44 In(Length)

So, we have to find 11 inches then

In(weight) = -5.28 + 3.44 x 11

               = -5.28 + 37.84

               = 32.56

Hence, 32.56 is the expected weight for a bluegill fish that is 11 inches long.

Indicated by the letter log n, the later class of logarithms, those with base 10, are referred to as common or Briggsian logarithms.

According to the question A line has a slope of -3 and includes the points (9, 4) and (8, t) then the value of t is 7

Typically, a line's slope provides information about the steepness and direction of the line. Finding the difference between the coordinates of the locations will allow you to quickly compute the slope of a straight line connecting two points, (x1,y1) and (x2,y2). The letter "m" is typically used to signify slope.

tan θ = Δy/Δx

the solution is -

Considering a line with a slope of -3 and also the point (9, 4), we could use the point-slope form of either a line to find the equation of a line:

y - 4 = -3(x - 9)

y = -3x + 27 + 4

y = -3x + 31

We are given some other point on the line (8, t) we can try substituting it in the equation above:

t = -3(8) + 31

t = -24 + 31

Step-by-step explanation:

We can write this out as an equation and let x represent the number:

7x-5=0

Adding five on both sides gives us: 7x=5

Therefore, x=5/7

Answer:

x = -3

y = 5

Step-by-step explanation:

3x + 2y = 1

5x + 4y = 5 ​

First, we multiply the first equation by -2

-6x -4y = -2

5x + 4y = 5

-x = 3

x = -3

Now put -3 back in for x and solve for y

3(-3) + 2y = 1

-9 + 2y = 1

2y = 10

y = 5

Let's check

3(-3) + 2(5) = 1

-9 + 10 = 1

1 = 1

So,  x = -3 & y = 5 is the correct answer.

The number of solutions to an equation x₁ + x₂ + x₃ + x₄ = 17 are 1140

Consider given equation x₁ + x₂ + x₃ + x₄  = 17,

where x₁ , x₂ , x₃ and x₄ are non-negative integers.

As we know x₁ is the number of ones before the first zero, x₂ the number of ones between the first and the second zero, x₃ the number of ones between the second and the third zero, and x₄ is the number of ones after the third zero.

This means, there is a 1-1 correspondence between the solutions and reorderings of 17 ones and 3 zeros.

So, the number of solutions to given equation would be,

n = ²⁰C₃

Using combination formula [tex]^nC_r=\frac{n!}{r!\times(n-r)!}[/tex],

A. The work done is 300 ft-lbs when a 100 lb rock is lifted to a height of 3 ft.

To calculate the work done, we can use the formula: Work = force x distance x cos(Ф).In this case, the force is the force of gravity acting on the rock, which can be calculated using the formula:

force = m * g

where m is the mass of the rock and g is the acceleration due to gravity (32.17 ft/s^2).

force = 100 lb * 32.17 ft/s^2 = 3,217 ft-lbs

The distance is the height to which the rock is lifted, which is 3 ft.

The angle of the rock to the vertical is 90 degrees, so cos(90) = 0.

So,

Work = force x distance x cos(theta) = 3,217 ft-lbs * 3 ft * 0 = 300 ft-lbs

So, the work done is 300 ft-lbs.
