Answer:

1 to 6

Step-by-step explanation:

Answer:

The quadratic equations and their solutions are;

9 ± √33 /4 = 2x² - 9x + 6.

4 ± √6 /2 = 2x² - 8x + 5.

9 ± √89 /4 = 2x² - 9x - 1.

4 ± √22 /2 = 2x² - 8x - 3.

Explanation:

Any quadratic equation of the form, ax² + bx + c = 0 can be solved using the formula x = -b ± √b² - 4ac / 2a. Here a, b, and c are the coefficients of the x², x, and the numeric term respectively.

We have to solve all of the five equations to be able to match the equations with their solutions.

2x² - 8x + 5, here a = 2, b = -8, c = 5.                                                  x = -b ± √b² - 4ac / 2a = -(-8) ± √(-8)² - 4(2)(5) / 2(2) = 8 ± √64 - 40/4.     24 can also be written as 4 × 6 and √4 = 2. So                                                                                     x = 8 ± 2√6 / 2×2= 4±√6/2.

2x² - 10x + 3, here a = 2, b = -10, c = 3.                                                   x =-b ± √b² - 4ac / 2a =-(-10) ± √(-10)² - 4(2)(3) / 2(4) = 10 ± √100 + 24/4. 124 can also be written as 4 × 31 and √4 = 2. So                                                                              x = 10 ± 2√31 / 2×2 = 5 ± √31 /2.

2x² - 8x - 3, here a = 2, b = -8, c = -3.                                                    x = -b ± √b² - 4ac / 2a = -(-8) ± √(-8)² - 4(2)(-3) / 2(2) = 8 ± √64 + 24/4.     88 can also be written as 4 × 22 and √4 = 2. So                                                                             x = 8 ± 2√22 / 2×2 = 4± √22/2.

2x² - 9x - 1, here a = 2, b = -9, c = -1.                                                     x = -b ± √b² - 4ac / 2a = -(-9) ± √(-9)² - 4(2)(-1) / 2(2) = 9 ± √81 + 8/4.                                          x = 9 ± √89 / 4.

2x² - 9x + 6, here a = 2, b = -9, c = 6.                                                    x = -b ± √b² - 4ac / 2a = -(-9) ± √(-9)² - 4(2)(6) / 2(2) = 9 ± √81 - 48/4.                                                                             x = 9 ± √33 / 4 .

Answer: -4096

Step-by-step explanation:

The 6th term of the geometric sequence is; -4096.

A geometric sequence is a sequence in which the result of the division of consecutive terms is always the same, called common ratio q.

The nth term of a geometric sequence is given as:

[tex]a_n = a_1q^{n-1}[/tex]

In which a1 is the first term.

For this problem, we have :

The first term is  a1 = 4 and an =- 4 an–1  .

Therefore, the common ratio is q = -4.

Now the 6th term of the sequence is found as :

[tex]a_6 = 4(-4)^{5[/tex]

a_6 = - 4096

Answer:

21.248

Step-by-step explanation:

The required value of decimal value 21.24833 to three decimal points is 21.248.

Given that,
21.24833, to round this number to 3 decimal places.

In mathematics, it deals with numbers of operations according to the statements.

Recurring Decimal is defined as also named repeating decimal, is a decimal number that only consists of repeating digits after a certain interval after the decimal. For example, 94.642642642..., 213.569569... etc.

In the question, a decimal value is given, 21.2488, and asked to round this off to 3 decimal places.

When rounding off the number, we check the preceding value neared to which zero either to 0 or 10. if it is near 0 the value before is round off value and the preceding value is near 10 then the value before the proceeding value is increased by 1.

In our case, the value after the third decimal is 3 which is near 0 so nothing will change and the value terminates as it is after 3 decimal points i.e 21.248.

Thus, the required value of decimal value 21.24833 to three decimal points is 21.248.

Given:

The set is

[tex]A=\{x:x^2=25\text{ and }6x=125\}[/tex]

To find:

Whether the given set is empty or not.

Solution:

A set is called empty set if it has no elements.

We have,

[tex]A=\{x:x^2=25\text{ and }6x=125\}[/tex]

We need to find the solutions of [tex]x^2=25[/tex] and [tex]6x=125[/tex]. The common solutions of these two equations are the elements of given set.

[tex]x^2=25[/tex]

[tex]x=\pm \sqrt{25}[/tex]

[tex]x=\pm 5[/tex]

[tex]x=5,-5[/tex]           ...(i)

And,

[tex]6x=125[/tex]

[tex]x=\dfrac{125}{6}[/tex]

[tex]x\approx 20.83[/tex]         ...(ii)

From (i) and (ii) it is clear that, there is no common value of x which satisfy both equations  [tex]x^2=25[/tex] and [tex]6x=125[/tex].

Since there is no element in set A, therefore, the given get A is an empty set.

Answer:

x= -24

Step-by-step explanation:

x/12=-2

12         x                               I did 12 times x/12 to get the x alone.

___  x ___ =   x

Do 12 times -2 too,

so..    12 x-2=-24

x= -24

The equation is:. Y = 4 .

The length of square B is 12 cm.

A scale factor is defined as the ratio between the scale of a given original object and a new object, which is its representation but of a different size (bigger or smaller).

The basic formula to find the scale factor of a figure is expressed as,

Scale factor = Dimensions of the new shape ÷ Dimensions of the original shape.

Given that, square A is 3 cm long.

The scale that maps square A onto square B is 1:4.

Let the length of square B be x.

1/4 =3/x

x=4×3

x=12 cm

Therefore, the length of square B is 12 cm.

Answer:

8: 90 degrees, 9: 165 degrees, 6: 81 degrees, 7: angles in the same segment are equal

Step-by-step explanation:

For question 8:

Notice how the line AB just barely touches the edge of the circle. We call this kind of line a tangent. The point O is at the center of the circle so the line OB is a radius. The angle between a tangent and a radius is always 90 degrees, so ABO is 90 degrees.

For question 9:

By the exact same logic as 8, ACO is also 90 degrees. The sum of interior angles in a 4 sided shape (a quadrilateral) is always 360 degrees. This means that 15 + 90 + 90 + x = 360 = 195 + x so x = 360 - 195 = 165

For question 6/7:

We use the theorem that the angles in the same segment are equal. This means that a is 81 degrees.

Answer:Bill gets £171

Step-by-step explanation:

Total Money shared = £399

The ratio of the amount Ann gets to bill gets is 2:9 Chloe and Dave get 2.5 times the amount Ann gets can be written as  

Ann : Bill   :     Chloe :   Dave

      2 : 9    : 2.5 x Ann :   2.5 x Ann

Let the amount of money

Ann gets be x

so that Bill gets 4.5x

Chloe = 2.5x

Dave = 2.5x  

So that the expression to calculate each amount gooten will be  

x + 4.5x + 2.5x + 2.5x = 399

10.5x = 399

x = 399/10.5

x=38

Therefore, Ann gets  = £38

Bill gets =4.5 x=   4.5 x £38 = £171

Chloe gets=2.5x =2.5 x £38  = £95

Dave gets=2.5x =2.5 x £38  = £95
