Value of quadratic equation is x = -1 and 11.

Define quadratic equation.

In mathematics, a quadratic equation is one with degree 2, which means that its maximum exponent is 2. A quadratic has the standard form y = ax² + bx + c, where a, b, and c are all numbers and a cannot be zero. All of these are examples of quadratic equations: the square root of the sum of the squares of the values, given by y = x² + 3x + 1. a degree 2 equation with just one variable. Ax² + bx + c = 0, where x is the variable and a, b, and c are constants (a 0), is its general form.

Given Data

Equation

x² - 10x -11 = 0

x² -11x + x -11 = 0

Completing the square,

x(x - 11) + 1(x -11) =0

Taking common,

(x+1)(x -11) =0

x = 11. -1

Value of quadratic equation is x = -1 and 11.

Ali takes out a loan to pay for a new sound system. The sound system costs
R7 700 and interest on the loan is 11 % simple interest per year.
If Ali repays the loan in a lump sum after 3 years, how much must he pay?

Answers

Using Simple Interest, Ali has to pay 10241 after 3 years.

What is simple interest?

Simple interest is the interest that is accrued at a specific rate and for a specific length of time on a particular principal. It is based on a loan's principal or the initial deposit into a savings account. Simple interest doesn't compound, therefore a creditor will only charge interest on the principal sum, and a borrower will never be required to pay further interest on the interest that has already accrued. Consider making a $100 (the principal) investment at a 5% yearly rate for a year. To calculate simple interest, multiply $100 by.05 interest per year to get $5 after a year.

If P is the principal, r is the rate, t is the time

SI = [tex]\frac{P \times r \times t}{100}[/tex]

Here,

Cost of sound system = 7700

Rate  = 11 %

Time = 3years

SI = [tex]\frac{7700 \times 11 \times 3}{100}[/tex]

  = 2541

Amount Ali has to pay after 3 year = 7700 + 2541

                                                        = 10241

Please help thanks so much

Answers

Answer:y=3x+11

Step-by-step explanation:

Use the points to calculate the slope. You would use the equation [tex]\frac{y_{2} -y_{1} }{x_{2} -x_{1} }[/tex] to get a slope of [tex]\frac{12}{4}[/tex]. That can be simplified to a slope of 3. Now find the y intercept. Now use the point (-1,8) to figure out what it would be when x=0. Everytime you add 1 to x it goes up by 3 so the point would be (0,11) and the y intercept would be 11.

Arrange the terms of the polynomial in descending Then, determine the degree of

5x 17X² + 22x

Answers

The terms of the polynomial, which has a degree of 2, are ordered as follows in decreasing order: 17x² + 27x

What in mathematics is a polynomial?

Sums of terms of the form  k⋅xⁿ where k is any number and n is a positive integer, make up polynomials. For instance, the polynomial 3x+2x-5.

How should a polynomial be organized?Typically, polynomials are set up in one of two ways. Basically, ascending order is when a term's strength grows with each consecutive term. In essence, descending order occurs when a term's power declines with each consecutive term.

Given polynomial: 5x + 17x² + 22x

We need to simplify this polynomial first.

5x + 17x² + 22x = 27x + 17x²

Now we will put the term with highest degree first and arrange the terms of this polynomial.

17x² + 27x

Since, the highest power of terms in this polynomial is 2.

We can say that the degree of polynomial is 2.

Therefore, the polynomial has a degree of 2 and its terms are arranged in decreasing order as follows: 17x² + 27x.

A pair of wireless headphones costs $125. Your friend has $40 and plans to save $15 each

Answers

The friend has to save for 5 and 2/3 of a month to in order to make up the remaining 85 to get the 125 headphone.

What is meant inequality graph?

An inequality that consists of two or more parts is called a compound inequality. Either "or" or "and" may be used in these components. A number between 5 and 10 could be used as x in an inequality, for instance, if it states that "x is larger than 5 and less than 10". Any time one of the two inequalities is true when the two inequalities are united by the word or, the compound inequality is solved. The two separate solutions have been combined to form the final answer. Inequalities that are separated by "and" or "or" form a compound inequality. The intersection of the inequality graphs is shown by the graph of a compound inequality with a "and."

Cost of the headphone 125.

What the friend have: 40.

What need to save: 125-40 = 85

Let x = amount to be saved per month

Months to save up the 85 is 15

The equation would be 15 x = 85

Therefore x = 85/15

the million americans of age and over control percent of all discretionary income. aarp estimated that the average annual expenditure on restaurants and carryout food was for individuals in this age group. suppose this estimate is based on a sample of persons and that the sample standard deviation is . round your answers to the nearest whole numbers. a. at confidence, what is the margin of error? b. what is the confidence interval for the population mean amount spent on restaurants and carryout food? , c. what is your estimate of the total amount spent by americans of age and over on restaurants and carryout food?

Answers

Using the t-distribution, it is found that:

a. The margin of error is of $122.4.

b. The 95% confidence interval for the population mean amount spent on restaurants and carryout food is of ($1,750.6, $1,995.4).

c. The estimate is the sample mean of $1,873.

What is a t-distribution confidence interval?

The bounds of the confidence interval are given according to the following rule:

[tex]\overline{x} \pm t\frac{s}{\sqrt{n}}[/tex]

In which the parameters are described as follows:

[tex]\overline{x}[/tex] is the sample mean, which is also the estimate of the population mean.t is the critical value.n is the sample size.s is the standard deviation for the sample.

In the context of this problem, the values of these parameters are given by:

[tex]\overline{x} = 1873, s = 550, n = 80[/tex]

Hence, for item c, the estimate is of $1,873, as it is the sample mean.

The critical value, using a t-distribution calculator, for a two-tailed 95% confidence interval, with 80 - 1 = 79 df, is t = 1.9905.

The margin of error is given by:

[tex]M = t\frac{s}{\sqrt{n}}[/tex]

Hence:

[tex]M = 1.9905\frac{550}{\sqrt{80}} = 122.4[/tex]

The confidence interval is the sample mean plus/minus the margin of error, hence:

1873 - 122.4 = $1,750.6.1873 + 122.4 = $1,995.4.

State if the three numbers can be the measures of the sides of a triangle. 1) 9, 7, 13 2) 26, 12, 11 3) 11, 2,9 4) 6, 11, 12 Two sides of a triangle have the following measures. Find the range of possible measures for the third side. 5) 12,9 7) 11,6 6) 8, 11 8) 12,8​

Answers

To determine if the three numbers can be the measures of the sides of a triangle:

According to the Triangle Inequality theorem to construct a triangle, the sum of the two sides of the triangle is greater than the third side i.e x + y>z

1) 9, 7, 13

So, 9+7 > 13

16 > 13

7+ 13 > 9

20 > 9

9+13 > 7

22 > 7

Yes, they can be the measures of the sides of a triangle.

2) 26, 12, 11

So, 26+12 > 11

38 > 11

12+ 11 > 26

23 < 26

No, they cannot be the measures of the sides of a triangle.

3) 11, 2,9

So, 11+2 > 9

13 > 9

2+ 9 > 11

11 = 11

No, they cannot be the measures of the sides of a triangle.

4) 6, 11, 12

So, 11+6 > 12

17 > 9

11+12 > 6 and 12+6 > 11

Yes, they can be the measures of the sides of a triangle.

To determine the range of the third side we find the maximum value and minimum value using two sides of a triangle.

Let's assume that x is the third side of the triangle.

5) 12,9

So, the maximum value of the third side is 12+9 = 21 and the minimum value is 12-9 = 3.

Hence, the range is 3<x<21.

6) 8, 11

The maximum value of the third side is 8+11 = 19 and the minimum value is 11-8 = 7.

Hence, the range is 3<x<19.

7) 11,6

The maximum value of the third side is 11+6 = 17 and the minimum value is 11-6 = 5.

Hence, the range is 5<x<17.

8) 12,8​

The maximum value of the third side is 12+8 = 20 and the minimum value is 12-8 = 4.

Hence, the range is 4<x<20.

about the origin?

Answers

The image of the point (1,3) after a counterclockwise rotation of 270° is (3, -1).

What is rotation?

Every point in a figure is transformed by a rotation, which rotates each point a predetermined amount of degrees around another point.

Given that : coordinate point is (1, 3)

When rotating a figure 270 degrees counterclockwise, each point must be changed from (x, y) to (y, -x) before the rotated figure may be graphed.

So, points (1,3) changed to (3, -1).

As a result, the image of the point (1,3) following a 270° counterclockwise revolution is (3, -1).
