Answer:

The solutions of the equation are √3 - 1/2 and -√3 - 1/2

Step-by-step explanation:

* Lets revise how to make the completing square

- The form of the completing square is (x - h)² + k, where h , k

 are constant

- The general form of the quadratic is x² + bx + c, where b , c

 are constant

- To change the general form to the completing square form equate  

 them and find the constant h , k

* Now lets solve the problem

∵ x² + x = 11/4 ⇒ subtract 11/4 from both sides

∴ x² + x - 11/4 = 0

- Put the equation equal the form of the completing square

∵ x² + x - 11/4 = (x - h)² + k ⇒ solve the bracket power 2

∴ x² + x - 11/4 = x² - 2hx + h² + k

- Equate the like terms

∵ x = -2hx ⇒ divide both sides by x

∴ 1 = -2h ⇒ divide both sides by -2

∴ -1/2 = h

∴ the value of h = -1/2

∵ -11/4 = h² + k

- Substitute the value of h

∴ -11/4 = (-1/2)² + k

∴ -11/4 = 1/4 + k ⇒ subtract 1/4 from both sides

∴ -12/4 = k

∴ k = -3

∴ The value of k is -3

- Substitute the value of h and k in the completing square form

∴ (x - -1/2)² + (-3) = 0

∴ (x + 1/2)² - 3 = 0 ⇒ add 3 to both sides

∴ (x + 1/2)² = 3 ⇒ take square root for both sides

∴ x + 1/2 = √3 OR x + 1/2 = -√3

∵ x + 1/2 = √3 ⇒ subtract 1/2 from both sides

∴ x = √3 - 1/2

OR

∵ x + 1/2 = -√3 ⇒ subtract 1/2 from both sides

∴ x = -√3 - 1/2

* The solutions of the equation are √3 - 1/2 and -√3 - 1/2

Answer:

The figure PEST is a rhombus

Step-by-step explanation:

* Lets talk about the difference between all these shapes

- At first to prove the shape is a parallelogram you must have one

 of these conditions

# Each two opposite sides are parallel OR

# Each two opposite sides are equal in length OR

# Its two diagonals bisect each other

- After that to prove the parallelogram is:

* A rectangle you must have one of these conditions

# Two adjacent sides are perpendicular to each other OR

# Its two diagonals are equal in length

* A rhombus you must have one of these conditions

# Two adjacent sides are equal in length OR

# Its two diagonals perpendicular to each other OR

# Its diagonals bisect its vertices angles

* A square you must have two of these conditions

# Its diagonals are equal and perpendicular OR

# Two adjacent sides are equal and perpendicular

* Now lets solve the problem

∵ The vertices of the quadrilateral PEST are

   P (-1 , -5) , E (8 , 2) , S (11 , 13) , T (2 , 6)

- Lets find the slope from each two points using this rule :

 m = (y2 - y1)/(x2 - x1), where m is the slope and (x1 , y1) , (x2 , y2)

 are two points on the line

- Let (x1 , y1) is (-1 , -5) and (x2 , y2) is (8 , 2)

∴ m of PE = (2 - -5)/(8 - -1) = 7/9

- Let (x1 , y1) is (8 , 2) and (x2 , y2) is (11 , 13)

∴ m of ES = (13 - 2)/(11 - 8) = 11/3  

- Let (x1 , y1) is (11 , 13) and (x2 , y2) is (2 , 6)

∴ m of ST = (6 - 13)/(2 - 11) = -7/-9 = 7/9

- Let (x1 , y1) is (2 , 6) and (x2 , y2) is (-1 , -5)

∴ m of TP = (-5 - 6)/(-1 - 2) = -11/-3 = 11/3

∵ m PE = m ST = 7/9

∴ PE // ST ⇒ opposite sides

∵ m ES = m TP = 11/3

∴ ES // TP ⇒ opposite sides

- Each two opposite sides are parallel

∴ PEST is a parallelogram

- Lets check if the parallelogram can be rectangle or rhombus or

 square by one of the condition above

∵ If two line perpendicular , then the product of their slops = -1

- Lets check the slopes of two adjacent sides (PE an ES)

∵ m PE = 7/9

∵ m ES = 11/3

∵ m PE × m ES = 7/9 × 11/3 = 77/27 ≠ -1

∴ PE and ES are not perpendicular

∴ PEST not a rectangle or a square (the sides of the rectangle and

  the square are perpendicular to each other)

- Now lets check the length of two adjacent side by using the rule

 of distance between two points (x1 , y1) and (x2 , y2)

 d = √[(x2 - x1)² + (y2 - y1)²]

- Let (x1 , y1) is (-1 , -5) and (x2 , y2) is (8 , 2)

∴ PE = √[(8 - -1)² + (2 - -5)²] = √[9² + 7²] = √[81 + 49] = √130 units

- Let (x1 , y1) is (8 , 2) and (x2 , y2) is (11 , 13)

∴ ES = √[(11 - 8)² + (13 - 2)²] = √[3² + 11²] = √[9 + 121] = √130 units

∴ PE = ES ⇒ two adjacent sides in parallelogram

∴ The four sides are equal

* The figure PEST is a rhombus

The simple interest formula is equal to

[tex]A=P(1+rt)[/tex]

where

A is the Final Investment Value

P is the Principal amount of money to be invested

r is the rate of interest  

t is Number of Time Periods

step 1

Find the rate of interest

in this problem we have

[tex]t=4\ years\\ P=\$18,000\\ A=\$21,600\\r=?[/tex]

substitute in the formula above and solve for r

[tex]\$21,600=\$18,000(1+4r)[/tex]

[tex]1.2=(1+4r)[/tex]

[tex]4r=1.2-1[/tex]

[tex]r=0.2/4=0.05[/tex]

The rate of interest is [tex]5\%[/tex]

step 2

To graph the function f(x) = -15x + 4, plot the points (0,4) and (1,-11) on the graph. The slope of the line is -15 and the y-intercept is 4.

To graph the equation f(x) = -15x + 4, you need to plot two points on a graph then draw a line through those points. First, plug in value x = 0 into the equation, you get f(0) = -15*(0) + 4 = 4. So, one point is (0,4). Second, let's plug another x value, for example, x = 1, into the function. Hence, f(1) = -15*(1) + 4 = -11, giving you the second point (1,-11).

Also remember that this is a linear function and you'll see that it forms a straight line when graphed. The slope of the line is -15, which means the line will fall to the right. The y-intercept of the line is 4, which is the point where the line crosses the y-axis.

The graph of f(x) = -15x + 4 is a line with a slope of -15 and a y-intercept of 4. Connecting points (0, 4) and (1, -11) depicts the downward-sloping trend.

To graph the linear function f(x) = -15x + 4, we can use the slope-intercept form y = mx + b, where m is the slope and b is the y-intercept. In this case, the slope (m) is -15, and the y-intercept (b) is 4.

To create the graph, we choose two points and connect them with a line. Let's select x = 0 and x = 1 to find the corresponding y-values.

For x = 0: y = -15(0) + 4 = 4. So, the point (0, 4) is on the graph.

For x = 1: y = -15(1) + 4 = -11. The point (1, -11) is on the graph.

Now, we can use these two points to draw the line on the coordinate plane. The line will have a negative slope, indicating a downward trend, and it intersects the y-axis at 4.

In summary, the graph of f(x) = -15x + 4 is a downward-sloping line that passes through the point (0, 4) and (1, -11).

= [tex]\frac{15}{100} =15%[/tex]

C) Dislike for tennis

Answer: X= -3/4, -1/2

Step-by-step explanation:

We can solve the problem in two equivalent ways:

if we compute the 45% of the price, we have

[tex]320\cdot \dfrac{45}{100} = 14.4[/tex]

and we subtract the discount from the original price:

[tex]320-144=176[/tex]

Alternatively, we can think as follows: if we discount the 45%, it means that we pay the remaining 55%, i.e. we pay

[tex]320\cdot \dfrac{55}{100} = 176[/tex]

To calculate the sale price, first calculate the discount by multiplying the original price by the discount percentage - 320 * 0.45. Then, subtract the value of the discount from the original price to get the sale price.

The subject of this question is mathematics, specifically percentages. In order to calculate the sale price of the television, we first need to calculate the amount of the discount. The discount can be calculated by multiplying the original price of the TV (£320) by the percentage of the discount (45%). In mathematical terms, this equation can be written as 320 * 0.45. Now, subtract the discount from the original price to find the sale price: 320 - (320 * 0.45).

The equation of the line parallel to y= (1/2) x−4 and passing through (-4, 2) is y= (1/2) x+4. The equation of the line perpendicular is y=−2x−6.

1. To find the slope of a line parallel to the given line y = (1/2)x - 4, we use the fact that parallel lines have the same slope. Therefore, the parallel line will also have a slope of 1/2.
2. Now, we can use point-slope form of linear equation, given by
[tex]y-y_1 =m(x-x_1),[/tex] where [tex](x_1 , y_1)[/tex] is a point on the line, m is the slope.
3. For the parallel line passing through (-4, 2),substitute [tex]x_1=-4, y_1 =2,[/tex] and m=1/2 into the point-slope form:
y−2= (1/2) (x+4)
4. Now, let's simplify equation to get in slope-intercept form (y=mx+b):
y−2= (1/2) x+2
5. Add 2 to both sides:
y= (1/2) x+4
6. So, the equation of the line parallel to y= (1/2) x−4 and passing through (-4, 2) is y= (1/2) x+4.
7. Now, to find the slope of a line perpendicular to the given line, we use the fact that perpendicular slopes are negative reciprocals. The slope of y= (1/2) x−4 is 1/2, so the perpendicular slope is -2.
8. Now, use the point-slope form again to find the equation of the line perpendicular to y= (1/2) x−4 and passing through (-4, 2):
y−2=−2(x+4)
9. Simplify:
y−2=−2x−8
10. Add 2 to both sides:
y=−2x−6
11. So, the equation of the line perpendicular to y= (1/2) x−4 and passing through (-4, 2) is y=−2x−6.

Answer:

The scale factor of their side lengths is 4:7.

Step-by-step explanation:

Let the side length of two squares are p and q.

The area of a square is

[tex]A=a^2[/tex]

Using this formula, we get the area of both squares.

[tex]A_1=p^2[/tex]

[tex]A_2=q^2[/tex]

It is given that the areas of two similar squares are 16m and 49m.

[tex]\frac{p^2}{q^2}=\frac{16}{49}[/tex]

[tex](\frac{p}{q})^2=\frac{16}{49}[/tex]

Taking square root both the sides.

[tex]\frac{p}{q}=\sqrt{\frac{16}{49}}[/tex]

[tex]\frac{p}{q}=\frac{4}{7}[/tex]

Therefore the scale factor of their side lengths is 4:7.

To find the scale factor of the side lengths, we can take the square root of the ratio of the areas. In this case, the scale factor is √7/2.

To find the scale factor of the side lengths of the squares, we can take the square root of the ratio of their areas. In this case, the ratio of their areas is 49m:16m, which simplifies to 7:4. Taking the square root of this ratio gives us the scale factor of their side lengths. So, the scale factor is √(7/4) = √7/√4 = √7/2. Therefore, the scale factor of the side lengths is √7/2.

Final answer:

The projectile reaches its maximum height after 22 seconds, which is determined by the vertex formula t = -b/(2a) applied to the given quadratic function representing the height over time.

Explanation:

To determine after how many seconds the projectile reaches its maximum height, we need to analyze the function h(t) = -16t2 + 704t. This is a quadratic function, and the maximum height will be reached at the vertex of the parabola represented by this function.

The vertex of a parabola given by ax2 + bx + c can be found using the formula t = -b/(2a), where a, b, and c are coefficients from the quadratic equation. In this case, a = -16 and b = 704.

Using the formula to find the time t when the projectile reaches its maximum height, we calculate: t = -704/(2 × -16) = 704/32 = 22. Therefore, the projectile reaches its maximum height after 22 seconds.

Without more information on the shape, it's not possible to provide the area of the figure from just the provided dimensions. Assuming it's a rectangle and using significant figures, the example calculation yields an area of 4.1 cm² when multiplying 0.6238 cm by 6.6 cm and rounding to two significant figures.

To find the area of a figure with given dimensions, one would typically multiply the length by the width. However, the question provided seems to be missing specific details about the shape of the figure. Given the figure's dimensions, if we assume it is a rectangle, the calculation would be straightforward: multiply the length by the width. Unfortunately, without additional information about the exact shape or context provided by equations or a figure reference, it is not possible to provide an accurate answer. It's essential to verify the shape and relevant equations before proceeding with the area calculation.

However, based on the examples given, to calculate the area with significant figures, one must consider the number of significant figures in the given dimensions. For example, if we multiply 0.6238 cm by 6.6 cm, the result is 4.11708 cm², which we round to 4.1 cm² (to two significant figures) because we are multiplying a number with four significant figures by a number with two significant figures.

The probability of not getting yellow is 2/3 ⇒ 3rd answer

Step-by-step explanation:

* Lets describe the meaning of experimental probability

- Experimental probability is the ratio of the number of times an

  event occurs to the total number of trials

∵ There are 6 blue marbles , 4 yellow marble and 2 red marbles

∴ the total number of marbles = 6 + 4 + 2 = 12 marbles

- The probability of each color is the number of the marbles have the

 same color divided by the total number of the marbles

∴ The probability of blue marbles = 6/12 = 1/2

∴ The probability of yellow marbles = 4/12 = 1/3

∴ The probability of red marbles = 2/12 = 1/6

- To find the probability of not yellow you can add the probability of

  blue and red OR subtract the probability of yellow from 1 because

  the total of probability of all colors is 1

∴ The probability of not yellow = 6/12 + 2/12 = 8/12 = 2/3

OR

∴ The probability of not yellow = 1 - 4/12 = 12/12 - 4/12 = 8/12 = 2/3

* The probability of not getting yellow is 2/3

Answer:

The correct answer is  3rd option

The probability of getting not yellow = 2/3

Step-by-step explanation:

It is given that, there are 6 blue marbles, 4 yellow marbles and 2 red marbles

To find the probability

Total number of marbles = 12 marbles

number of yellow marbles = 4 marbles

probability of getting yellow = 4/12 = 1/3

probability of getting not yellow = 1 - 1/3 = 2/3

Therefore the correct answer is 3rd option
