The examples of error and trial method and quadratic system are shows below.

Number problems and try to solve either trial and error or a Quadratic System

Trial and error is a fundamental method of Problem solving. It is characterized by repeated, varied attempts which are continued until success, or until the agent stops trying. Until getting the right answer the problem is repeating through various steps. This type of problem solving is called trial and error method.

A linear quadratic system is a system containing one linear equation and one quadratic equation (which is generally one straight line and one parabola). A simple linear system contains two linear equations (which is two straight lines).

ERROR AND TRIAL METHOD

Question: 44 people live in eight houses (3 on each side of the Albert Square). Each house has a different number of people living in it. Each line of three houses has 15 people living in it. How many people live in each house?

Solution: Simplifying, we have to get 4 sets of numbers, each of which add up to 15. So start guessing.

The average number of people in a house is 44/8 is roughly 4.5. So what numbers should we take? 2, 3, 4, 5, 6, 7, 8, 9. Now, we should also have an average close to 5 for each set. Let's start:

Set 1: 3, 5, 7

Set 3: 2, 4, 9

Now, the other two sets will have an overlap. So let's guess the overlaps:

Set 2: Overlaps are 2 and 7. So the third number will be 6. Because we have not used 6 yet.

Set 4: Overlaps are 3 and 9. Then the third number ends up to 3 again. Wrong guess! So we need to try again. Overlaps are 3 and 4. In this case third number works out to be 8, which we have not used. So here is the answer

The first row: 2,6,7.

Second row: 4,8,3.

First column : 2,9,4.

Second column: 7,5,3.

QUADRATIC SYSTEM:

Find the points of intersection between the line y=2x+1  and the parabola y=x2−2.

Substitute 2x+1  for y in y=x2−2.

2x+1=x2−2

Write the quadratic equation in standard form.

2x+1−2x−1=x2−2−2x−10=x2−2x−3

Use the quadratic formula to find the roots of the quadratic equation.

Here, a=1,  b=−2,  and c=−3.

x=−(−2) ± (−2)2 − 4(1)(−3)√2(1)=2 ± 4 + 12√2=2 ± 42=3,  −1

Substitute the x-values in the linear equation to find the corresponding y-values.

x=3⇒y=2(3)+1

 =7x=−1⇒y=2(−1)+1      =−1

Therefore, the points of intersection are (3,7)  and (−1,−1).

Answer:

<

Step-by-step explanation:

The value of x, at which the second function's output exceeds  the first function's output is

[tex]$x \in\left(-\infty, \frac{1-\sqrt{29}}{2}\right) \cup\left(\frac{1+\sqrt{29}}{2}, \infty\right)$[/tex]

This is further explained below.

Generally, The second function's output exceeds (get bigger than) the first function's output for

[tex]$x \in\left(-\infty, \frac{1-\sqrt{29}}{2}\right) \cup\left(\frac{1+\sqrt{20}}{2}, \infty\right)$[/tex]

Given the functions f(x)=x+7 and f(x)=x^2

To know when to exceed, need to equate both functions.

[tex]$$\begin{aligned}&\Rightarrow x^2=x+7 \\&\Rightarrow x^2-x-7=0 \\&\mathrm{x}=\frac{-b+\sqrt{D}}{2 a} \text { and } \frac{-b-\sqrt{D}}{2 a} \\&\Rightarrow \mathrm{x}=\frac{1-\sqrt{29}}{2}, \frac{1+\sqrt{29}}{2}\end{aligned}$$[/tex]

f(x)=x^2 drops from infinity to zero and grows from zero to infinity; it cuts the graph of x+7 twice, and for each of those instances, it results in the same shape.

[tex]x \in\left(-\infty, \frac{1-\sqrt{29}}{2}\right) \cup\left(\frac{1+\sqrt{29}}{2}, \infty\right) f(x)=x^2$[/tex]  is greater than f(x)=x+7

As a result, the output of the second function surpasses (acquires a greater size than) the output of the first function for

[tex]$x \in\left(-\infty, \frac{1-\sqrt{29}}{2}\right) \cup\left(\frac{1+\sqrt{29}}{2}, \infty\right)$[/tex]

The LCM of the given polynomials x² - 81 and x² - 2x - 63 is (x - 9)(x + 7)(x + 9), which on expansion looks like x³ + 7x² - 81x - 567.

In the question, we are given two polynomials x² - 81 and x² - 2x - 63.

We are asked to find the LCM of the given polynomials.

To find the LCM of two polynomials, we multiply all the factors of both polynomials uniquely.

So first, we factor both the given polynomials.

x² - 81

= x² - 9² [∵ 81 = 9²],

= (x + 9)(x - 9) [Using the formula a² - b² = (a + b)(a - b)].

x² - 2x - 63

= x² - 9x + 7x - 63 [Mid-term factorization],

= x(x - 9) + 7(x - 9) [Grouping],

= (x + 7)(x - 9) [Grouping].

After factorizing the polynomials, we can note that the unique factors of x² - 81 and x² - 2x - 63 are (x + 9), (x -9), and (x + 7).

Thus, the LCM can be shown as their products, which is:

LCM = (x - 9)(x + 7)(x + 9), which on expansion looks like x³ + 7x² - 81x - 567.

Answer:

54.7

Step-by-step explanation:

19% of 288

0.19 * 288 = 54.72

54.72 = 54.7

Answer:

Estimated 60 and rounded 55 and normal 54.72.

Step-by-step explanation:

To get the estimated answer, first convert the percentage to a decimal: 19% = 0.19. Second, you have to round the 2 numbers so they are easier to multiply: 0.19 = 0.20 and 288 = 300. Now that you have the 2 rounded numbers, you can multiply them to get the estimated answer: 0.20 x 300 = 60 so 60 is your estimated answer.

To get the rounded answer, you first have to multiply the 2 given numbers, the whole number and the percentage (as a decimal), together: 0.19 = 54.72. Now that you have the answer to the multiplication problem, you can round the answer to the nearest whole number: 54.72 = 55 so the rounded answer is 55.

To get the exact answer, all you have to do is multiply the percentage (as a decimal), by the whole number to get the answer: 0.19 x 288 is 54.72 so the exact answer is 54.72.

Answer:

16,384

Step-by-step explanation:

4^4 = 4×4×4×4=256

8^2 = 8×8=64

256×64=16,384

Answer:

16384 or [tex]2^{14}[/tex]

Step-by-step explanation:

This is easiest done by creating identical bases (the number being raised by the exponent, 4 and 8 here).

How do we do that? Well let’s start with [tex]4^{4}[/tex].

For both 8 and 4 the bases can be rooted to 2

[tex]\sqrt[3]{8} = 2 \\ \sqrt{4} = 2[/tex]

Because the root of 4 is 2, that means [tex]2^{2} =4[/tex].
Therefore, we can substitute [tex]2^{2}[/tex] for 4 in [tex]4^{4}[/tex], which looks like this:

[tex]2^{2^{4} }[/tex]

And, we should know that an exponent raised to an exponent is the same as multiplying those exponents together. This means [tex]2^{2^{4}} =2^{8}[/tex].

We can repeat the process with [tex]8^{2}[/tex]

[tex]8 = 2^{3} \\8^{2} =2^{3^{2} } \\2^{3^{2} } =2^{6}\\8^{2}=2^{6}[/tex]

Now that we have [tex]2^{8}\ and\ 2^{6}[/tex] we can continue. Given that the bases are the same we can simply add the exponents together when we multiply.

[tex]2^{8}[/tex] x [tex]2^{6}[/tex] = [tex]2^{14}[/tex] (or 16384).

The maximum and minimum set of dimension for the rectangular field are-

A rectangle is a four-sided configuration with 90-degree angles at all four corners. A rectangle's sides are same length than the one opposite it.

The perimeter of the rectangular field is given in the form of equation;

4x + 3y = 100

Where the total area is given as;

y(x+x) = 374

2xy = 374

Solving the equation;

(4 x+3 y)² = 16x² + 12×2 x y + 9 y² = 10000

2 x y = 374,12.

2 x y = 12 × 374

2 x y = 4488

16x² + 9 y² = 10000 - 4488

16x² + 9 y² = 5512

Now, solve for the other set of value;

(4 x-3 y)² =  16x² - 12×2 x y + 9 y²

Put the value of 16x² + 9 y² = 5512.

(4 x-3 y)² =  5512 - 12×2 x y

Put 2xy = 374

(4 x-3 y)² =  5512 - 4488

(4 x-3 y)² = 1024

Case1: 4 x-3 y = √{1024}

4 x-3 y = 32

And, 4 x + 3 y = 100

Solving both;

8x = 132

x = 16.5

and y = (100 - 32)/6

y = 11.33

Case 2: 4 x - 3 y = -32

4 x + 3 y = 100

Solving both by elimination method.

x = 8.5 and y = 22

Thus, the minimum and maximum dimension for the rectangular garden are-

Maximum (x, y) = (8.50, 22)

Minimum (x, y) = (16.50, 11.33)

The two fractions that will give a sum between 0.75 and 1 are 3/7 + 5/9 and the larger fraction is 5/9

We want to find two fractions using the digits 3, 5, 7 and 9 to find the one that gives a sum between 0.75 and 1.

Since it has to be a sum between 0.75 and 1, it means that the denominator must be greater than the numerator. Thus, let us try as follows;

3/5 + 7/9

Factorize out 45 to get;

¹/₄₅((3 * 9) + (7 *5))

= ¹/₄₅(27 + 35)

= ¹/₄₅(52)

This will not work because it will lead to a sum greater than 1

Let us try another one;

3/7 + 5/9

Factorize out 63 to get;

¹/₆₃((3 * 9) + (5 *7))

= ¹/₆₃(27 + 35)

= 52/63

= 0.8254

Thus, the two fractions that will give a sum between 0.75 and 1 are 3/7 + 5/9 and the larger fraction is 5/9
