Answer:

x = 5 + [tex]\sqrt{7}[/tex]

x = 5 - [tex]\sqrt{7}[/tex]

Step-by-step explanation:

The given quadratic equation is:

x^2 - 10x + 18 = 0

We can solve this equation using the quadratic formula, which states that for a quadratic equation of the form ax^2 + bx + c = 0, the solutions for x are given by:

x = (-b ± sqrt(b^2 - 4ac)) / 2a

In this case, a = 1, b = -10, and c = 18. Substituting these values into the quadratic formula, we get:

x = (-(-10) ± sqrt((-10)^2 - 4(1)(18))) / 2(1)

Simplifying the expression inside the square root, we get:

x = (10 ± sqrt(100 - 72)) / 2

x = (10 ± sqrt(28)) / 2

x = (10 ± 2sqrt(7)) / 2

Simplifying further, we get:

x = 5 ± [tex]\sqrt{7}[/tex]

The height of the parallelogram is 5.4 units.

What is area ?

In mathematics, the area is the measure of the size of a two-dimensional surface or region, usually expressed in square units, such as square inches or square meters. The area of a flat shape or planar figure is the amount of space inside its boundary, or the surface of the object, that is covered by a two-dimensional geometric shape.

One way to find the height is to draw a perpendicular line from point B to line segment AD, forming a right triangle. Let's call the length of this perpendicular line h.

Now we can see that the base of the parallelogram is 10 units (from A to D), and the height is h units (from B to the perpendicular line we drew). The area of the parallelogram is given as 54 units², so we can set up the following equation:

Area = base x height

54 = 10h

Solving for h, we get:

h = 54/10 = 5.4

Therefore,  the height of the parallelogram is 5.4 units.

Step-by-step explanation:

5/6 - 2/5 = 25/30 - 12/30 = 13/30

Answer:

Step-by-step explanation:

To subtract two fractions, we need a common denominator. The smallest number that 6 and 5 both divide into is 30.

Converting the fractions to have 30 as the denominator, we get:

5/6 = 25/30

2/5 = 12/30

Now we can subtract:

25/30 - 12/30 = 13/30

Therefore, 5/6 - 2/5 = 13/30 in simplest form.

The number of messages are: Martina sent 21 messages, Ryan sent 14 messages, and Keith sent 42 messages.

We may build equations that link unknown values in a problem and describe those numbers using variables. We may modify these equations algebraically to get solutions for the unknowable numbers by employing variables. As a result, issue solving is more effective and we can come up with generic answers that may be used in a variety of situations. Moreover, employing variables enables us to see patterns and trends as well as better grasp the connections between various amounts in a situation.

Given that,

Ryan sent 7 fewer messages than Martina.

R = M - 7

Keith sent 2 times as many messages as Martina.

K = 2M

Martina, Ryan, and Keith sent a total of 77 text messages.

M + R + K = 77

Substitute the value of equation 1 and 2 in equation 3:

M + (M - 7) + 2M = 77

4M - 7 = 77

4M = 84

M = 21

Substitute the value of M in equation 1 and equation2:

R = M - 7 = 21 - 7 = 14

K = 2M = 2(21) = 42

There is a 2.28% chance that more than 250 books were borrowed in a week.

Probability can also be calculated using other methods, such as counting techniques and probability distributions. Probability distributions provide a way to model the behavior of random events and describe the likelihood of different outcomes occurring.

Probability has many applications in fields such as statistics, finance, engineering, and science. It is used to make predictions, analyze data, and make decisions based on uncertain information. Understanding probability is an important skill for many professions, as it allows individuals to make informed decisions and assess risk.

To solve this problem, we need to use the standard normal distribution and calculate the z-score.

First, we find the z-score:

z = (x - μ) / σ

z = (250 - 190) / 30

z = 2

We can then use a standard normal distribution table or calculator to find the probability of getting a z-score of 2 or higher.

Using a standard normal distribution table, we find that the probability of getting a z-score of 2 or higher is approximately 0.0228.

To convert this to a percentage, we multiply by 100:

0.0228 x 100 = 2.28%

Therefore, there is a 2.28% chance that more than 250 books were borrowed in a week.

For function f(x)= -4x²-4x-1,   f(x+h)= -4x² - 8xh - 4h² - 4x - 4h - 1, (f(x+h) - f(x))/h= -8x - 4h - 4

The input values of a function are called the domain, and the output values are called the range. The domain can be any set of values, but each input value must have a unique corresponding output value. If there are multiple input values that produce the same output value, the function is not considered to be well-defined. Functions are used to model a wide range of phenomena in many different fields, including science, engineering, and economics. They are also used in calculus to study rates of change and slopes of curves.

To find f(x+h), we need to replace x with (x+h) in the given function:

f(x+h) = -4(x+h)² - 4(x+h) - 1

= -4(x² + 2xh + h²) - 4x - 4h - 1

= -4x² - 8xh - 4h² - 4x - 4h - 1

To find (f(x+h) - f(x))/h, we first need to find f(x):

f(x) = -4x² - 4x - 1

Then we can substitute f(x+h) and f(x) in the formula:

(f(x+h) - f(x))/h = (-4x² - 8xh - 4h² - 4x - 4h - 1 - (-4x² - 4x - 1))/h

= (-4x² - 8xh - 4h² - 4x - 4h - 1 + 4x^2 + 4x + 1)/h

= (-8xh - 4h² - 4h)/h

= -8x - 4h - 4

So, f(x+h) = -4x² - 8xh - 4h² - 4x - 4h - 1, and (f(x+h) - f(x))/h = -8x - 4h - 4.

The slope of each line represents the cost of tomatoes/pound.

The y-intercept of each line represents the bus fare.

To determine which point would not be found on the line, we can use the slope-intercept form of the equation of a line, which is:

y = mx + b

As per the given data:

Tomatoes from Grandiose Grocers = $2.50/pound

Tomatoes from EconoFoods = $2/pound

Bus fare for EconoFoods = $3

The x-axis should be the number of pounds of tomatoes bought.

The y-axis should be the total cost of x pounds of tomatoes.

For Grandiose Grocers:

y = 2.50x

For EconoFoods:

y = 2x + 3

From comparing with the slope-intercept form of a line, y = mx + c

m(Grandiose Grocers) = 2.50 {cost of tomatoes per pound}

m(EconoFoods) = 2 {cost of tomatoes per pound}

c is the y intercept:

c(Grandiose Grocers) = 0 {bus fare is $0}

c(EconoFoods) = 3 {bus fare is $3}

A linear equation in the form p = mn + b that gives the price they can charge for n shirts is p = -0.003x + 22.

In Mathematics, the point-slope form of a straight line can be calculated by using this mathematical expression:

y - y₁ = m(x - x₁) or y - y₁ = (y₂ - y₁)/(x₂ - x₁)(x - x₁)

Where:

At data point (1000, 19), a linear function in standard form for this line can be calculated by using the point-slope form as follows:

y - y₁ = (y₂ - y₁)/(x₂ - x₁)(x - x₁)

y - 19 = (16 - 19)/(2000 - 1000)(x - 1,000)

y - 19 = -0.003(x - 1,000)

The formula for the volume of a cone is:

V = (1/3)πr^2h

Solving for r:

V = (1/3)πr^2h

3V = πr^2h

r^2 = (3V)/(πh)

r = sqrt[(3V)/(πh)]

Given that V = 660cm^3, h = 14cm and π = 22/7:

r = sqrt[(3 × 660)/(22/7 × 14)] ≈ 7 cm

So the radius is approximately 7 cm.

To find the value of h:

V = (1/3)πr^2h

660 = (1/3)(22/7)(7^2)h

660 = (22/3)(49/7)h

660 = (22/3)(7)h

h = 660 / [(22/3)(7)]

h = 9.45 cm (rounded to two decimal places)

Therefore, the value of h when the volume of the cone is 660 cm^3 is approximately 9.45 cm.

The quilt has an 8 x 8 array of square patches, which means it has a total of 8 x 8 = 64 square patches. Each square patch is 2 2/3 inches long.

To find the area of the whole quilt, we need to find the total area covered by all 64 square patches. We can do this by multiplying the length and width of one square patch by the total number of patches:

Area of one square patch = length x width = (2 2/3 in) x (2 2/3 in) = (8/3 in) x (8/3 in) = 64/9 sq in
