The roots of the equation [tex]x^{2}[/tex]-3x-3=0 by completing the square method are 3.79 and -0.79.

Given that the equation is [tex]x^{2}[/tex]-3x-3=0.

We are required to find the roots of the equation by completing the square method.

Equation is basically the relationship between two or more variables that are expressed in equal to form. It may be linear equation, quadratic equation,cubic equation and many more depending on the power of the variables that are present in the equation.

The equation is  [tex]x^{2}[/tex]-3x-3=0.

[tex]x^{2}[/tex]-3x=3

[tex](x+3/2)^{2}[/tex]=-(c-[tex]b^{2}[/tex]/4)

So,

[tex](x-3/2)^{2}[/tex]=-[-3-[tex](-3)^{2}[/tex]/4]

[tex](x-3/2)^{2}[/tex]=-[-3-9/4]

[tex](x-3/2)^{2}[/tex]=21/4

x-3/2=±[tex]\sqrt{21}[/tex]/2

x=([tex]\sqrt{21}[/tex]+3)/2,(-[tex]\sqrt{21}[/tex]+3)/2

x=(4.58+3)/2, (-4.58+3)/2

x=7.58/2, -1.58/2

x=3.79,-0.79

Hence the roots of the equation [tex]x^{2}[/tex]-3x-3=0 by completing the square method are 3.79 and -0.79.

Answer:

45

Step-by-step explanation:

The four factors were used to create this Product Game board are  {2, 3, 5, 7} and the product missing from the grid is 25

To see what are factors are used in the given list, we just need to write each of the numbers, as a product of prime factors such as 2, 3, 5, 7 .

9 = 3* 3

15 = 3 *5

18 = 3 *2*3

21 = 7*3

30 = 5*3*2

35 = 7*5

36 = 3*3*2*2

42 = 2*3*7

49 = 7*7

As we can see, the 4 factors used to product the numbers in the given list are {2, 3, 5, 7}

for the second part that is to find the missing number between 21 and thirty we first need to write all the numbers between 21 and thirty and check which number is having the only factors of at least one of (2,3,5,7)

the numbers are 22 , 23 ,24, 25 ,26 ,27 ,28, 29

After checking the missing number is 25(5*5) because there has to be at least 4 products who have same factor and 5 is the factor who has appeared only three times

The correct answer is Team B won by 1.1 points.

To determine which team won the competition, we need to calculate the final scores for both Team A and Team B based on the given weights for each category and the points they received in each category.

For Team A:

- Time to complete (75% of 15 points) = 0.75 * 15 = 11.25 points

- Design (15% of 9 points) = 0.15 * 9 = 1.35 points

- Total cost (10% of 14 points) = 0.10 * 14 = 1.4 points

Total score for Team A = 11.25 + 1.35 + 1.4 = 14 points

For Team B:

- Time to complete (75% of 17 points) = 0.75 * 17 = 12.75 points

- Design (15% of 7 points) = 0.15 * 7 = 1.05 points

- Total cost (10% of 13 points) = 0.10 * 13 = 1.3 points

Total score for Team B = 12.75 + 1.05 + 1.3 = 15.1 points

Now, we compare the total scores of both teams. Team A has a total score of 14 points, while Team B has a total score of 15.1 points. Therefore, Team B won by 1.1 points.

The equation of the line in fully simplified slope-intercept form is y = -x - 8.

It is assumed that a line in the graph will pass through some points on the x and y-axes.

We must determine the line's fully simplified intercept.

we know the standard form of a line that is

y = mx + b

here, m is a slope and b is the constant

On the graph, there are the y-intercept (0,-8) and the x-intercept (-8,0).

The slope of the line passing through these points is:

[tex]slope = \frac{y2 - y1}{x2 - x1} \\ [/tex]

[tex]slope = \frac{ 8 - 0}{ 0 - 8} [/tex]

slope = 8/(-8)

slope = -1

then find the value of b

if x = 0 y = -8 then

y = mx +b

-8 = -1(0) + b

-8 = b

the value of b is -8

After inserting the values for m and c, the line's equation will be.

y = - x - 8

Hence y = -x - 8 is the equation of the line in fully simplified slope-intercept form.

Simple Interest is the method of finding the interest amount for a particular principal amount of money at a particular rate of interest.

The simple interest for $900 at an interest rate of 6% is $108.

Simple Interest is the method of finding the interest amount for a particular principal amount of money at a particular rate of interest.

We have,

Principal = $900

Rate of interest = 6%

Time = 2 years.

Remember that time should always be in years.

The formula for simple interest is given by:

SI = PRT / 100

Where,

P = principal

R = rate of interest

T = Number of years

So,

SI = 900 x 6 x 2 / 100

SI = $108

Thus the simple interest for $900 at an interest rate of 6% is $108.

Original sides of the square before reducing was 11 inches.

A quadratic equation has highest degree of two and it has 2 roots.

According to the given question Miriam reduced a square photo by cutting 3 inches away from the length and the width so it will fit in her photo album.

Assuming sides of the square to be x inches.

∴ From the given data

( x - 3 )( x - 3 ) = 64         ( area of a square is product any two sides )

x² - 6x + 9 = 64

x² - 6x - 55 = 0

x² - 11x + 5x - 55 = 0

x( x - 11 ) + 5( x-11 ) = 0

(x - 11 )( x + 5) = 0

∴ x = 11 or x = -5.                  ( length of something can not be negative )

So, the original length of the sides of the square is 11 inches.

Original area is

Answer:

a geometric model shows the lay out of places like earth it tells us where our best water sources are.

Answer: w can be 1,2,4,5

Step-by-step explanation:

Let's recap the formula of Area:
Area = width x length = w x l
Area = 40 = w x l

The definition of a whole number: is a number without fractions; an integer such as 0, 1, 2, 3, 4, 5, 6,...

Let's start with 0. 0 times anything is equal to 0, so we cannot make 40 out of zero. Cross this out.

Next, let's try with 1:

a. 1x40 = 40

Then, applying the same concept to the rest we have these multiplications:

b. 2x20 = 40

c. 4x10 = 40

d. 5x8 = 40

e. 8x5 = 40

f. 10x4 = 40

g. 20x2 = 40

h. 40x1 = 40

Let's recap the formula of Perimeter:

P = 2 x (w + l)

So, we have the calculated perimeters (according to the above finding):
a. P= 2x(1+40)=82

b. P= 2x(2+20)=44

c. P= 2x(4+10)=28

d. P= 2x(5+8)=26

The perimeter of a polygon is 24 units.

In this question, we have been given the coordinates of a polygon.

we need to find the perimeter of a polygon.

Let A= (-3,2), B = (2,2), C = (2,-4), D = (-1,-4), E = (-1,-2), F = (-3,-2)

First we find the length of each side of a polygon.

|AB| = √5² + 0²

|AB| = 5

|BC| = √0² + (-6)²

|BC| = 6

|CD| = √(-3)²+0²

|CD| = 3

|DE| = √0²+2²

|DE| =  2

|EF| = √(-2)²+0²

|EF| = 2

|FA| = √0²+4²

|FA| = 4

The perimeter of a polygon would be,

P = AB + BC + CD + DE + EF + FA

P = 5 + 6 + 3 + 2 + 2 + 4

P = 24 units

The first term of the Geometric Series = 3 and its common ratio = 3/2.

An unlimited number of terms with a fixed ratio between each term make up a geometric series.

For 'n' termed GP with a = first term and r = common ratio, [tex]S_{n}=\frac{a(r^{n}-1)}{r-1}[/tex]

Given:

To find: First term of the GP and the common ratio.

Finding:

As, [tex]S_{n}=\frac{a(r^{n}-1)}{r-1}[/tex], for n =3,

[tex]S_{3}=\frac{a(r^{3}-1)}{r-1}=14.25[/tex] (eqn 1)

=> Similarly for n = 4,

[tex]S_{4}=\frac{a(r^{4}-1)}{r-1} = 24.375[/tex]

On dividing [tex]S_3 by S_4[/tex], we get:

[tex]\frac{14.25}{24.375}=\frac{r^{3}-1}{r^{4}-1}[/tex]

=> On solving the equations, we get:

[tex]14.25r^{4}-24.375r^{3}+10.125=0[/tex]

r = 3/2 (on factorizing the equation)

Now, substituting this in eqn 1

=> [tex]14.25=\frac{a((\frac{3}{2})^{2}-1)}{\frac{3}{2}-1}[/tex]

=> a = 3 on further solving the equation for a.

Hence, the first term of the Geometric Series = 3 and its common ratio = 3/2.
