Answer:

[tex]y=-4x+5[/tex]

Step-by-step explanation:

Step 1:  Find the slope

[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

[tex]m=\frac{13-5}{-2-0}[/tex]

[tex]m=-\frac{8}{2}[/tex]

[tex]m=-4[/tex]

Step 2:  Use point slope form

[tex](y-5) = -4(x-0)[/tex]

[tex]y-5 + 5=-4x + 5[/tex]

[tex]y=-4x+5[/tex]

Answer:  [tex]y=-4x+5[/tex]

y=-4x+5

Step-by-step explanation:

Step 1:  Find the slope

m=\frac{y_2-y_1}{x_2-x_1}

m=\frac{13-5}{-2-0}

m=-\frac{8}{2}

m=-4

Step 2:  Use point slope form

(y-5) = -4(x-0)

y-5 + 5=-4x + 5

y=-4x+5

The 24th term is 152

Step-by-step explanation:

The formula of the nth term of an arithmetic sequence is:

[tex]a_n=a+(n-1)d[/tex] , where

The third term means n = 3

∵ [tex]a_3=a+(3-1)d[/tex]

∴ [tex]a_3=a+2d[/tex]

∵ [tex]a_3[/tex] = 5

- Equate the right hand sides of the third term

∴ a + 2d = 5 ⇒ (1)

The fifth term means n = 5

∵ [tex]a_5=a+(5-1)d[/tex]

∴ [tex]a_5=a+4d[/tex]

∵ [tex]a_5[/tex] = 19

- Equate the right hand sides of the fifth term

∴ a + 4d = 19 ⇒ (2)

Now we have a system of equations to solve it

Subtract equation (1) from equation (2) to eliminate a

∴ 2d = 14

- Divide both sides by 2

∴ d = 7

- Substitute the value of d in equation (1) to find a

∵ a + 2(7) = 5

∴ a + 14 = 5

- Subtract 14 from both sides

∴ a = -9

The twenty fourth term means n = 24

∵ a = -9 and d = 7

- Substitute the values of a and d in the formula of the nth term

∴ [tex]a_24=-9+(24-1)(7)[/tex]

∴ [tex]a_24=-9+(23)(7)[/tex]

∴ [tex]a_24=-9+161[/tex]

∴ [tex]a_24=152[/tex]

The 24th term is 152

Answer:

m = 0.75

Step-by-step explanation:

Since (m, 2m + 1 ) is a solution of the equation then substituting the values into the equation will make it true, that is

substitute x = m and y = 2m + 1 into the equation, thus

4m + 2(2m + 1) = 8 ← distribute and simplify left side

4m + 4m + 2 = 8

8m + 2 = 8 ( subtract 2 from both sides )

8m = 6 ( divide both sides by 8 )

m = [tex]\frac{6}{8}[/tex] = [tex]\frac{3}{4}[/tex] = 0.75

Answer: b= -3

Step-by-step explanation:

The question focuses on Mathematics, specifically Geometry and Calculus. It requires calculating the area of geometric figures especially circles and disks in terms of π, often via the formula A=πr² or integration.

From the question, we are required to find the area of shaded parts, which essentially associates with geometric figures and their properties in Mathematics. Specifically, this question appears to focus on areas related to circles and spheres, as it mentions calculations in terms of π, radius (r) and certain formulas like A=πr², which is the formula for the area of a circle.

When asked to express something in terms of π, it typically means leaving the answer as multiples of π, rather than using its decimal equivalent. So for instance, if we calculated the area of a circle with a radius of 3 using A=πr², we would say that the area is 9π.

Another crucial information that surfaced in the materials provided is the area calculation using integration, which involves adding up the individual areas of 'thin rings' from r=0 to r=R where R is the total radius of the disk or circle. This is an important aspect of finding areas under curves or finding areas enclosed by curves in Calculus.

The area of the shaded regions is [tex]\(8\pi - 8\)[/tex] square centimeters.

To find the area of the shaded regions in the circle with the inscribed triangle, we'll follow these steps:

1. Calculate the Area of Sector AOC:

  - The sector's central angle is 90° because triangle AOC is right-angled at C.

  - The area of a sector is [tex]\( \frac{\theta}{360} \times \pi \times r^2 \)[/tex], where [tex]\( \theta \)[/tex] is the central angle and [tex]\( r \)[/tex] is the radius.

  - Here, [tex]\( r = 4 \) cm and \( \theta = 90° \).[/tex]

  - So, the area of sector AOC is [tex]\( \frac{90}{360} \times \pi \times 4^2 = \pi \times 4 \) cm^2.[/tex]

2. Calculate the Area of Triangle AOC:

  - The area of a triangle is [tex]\( \frac{1}{2} \times \text{base} \times \text{height} \).[/tex]

  - For triangle AOC, the base and height are both equal to the radius, which is 4 cm.

  - So, the area of triangle AOC is [tex]\( \frac{1}{2} \times 4 \times 4 = 8 \)[/tex] cm².

3. Calculate the Area of the Shaded Segment on the Opposite Side:

  - Subtract the area of triangle AOC from the area of sector AOC.

  - This gives us the area of the shaded segment: [tex]\( \pi \times 4 - 8 \)[/tex] cm².

Combining both shaded areas, the total area of the shaded regions is [tex]\( \pi \times 4 + (\pi \times 4 - 8) \)[/tex] cm², which simplifies to [tex]\( 8\pi - 8 \)[/tex] cm². Therefore, the area of the shaded regions is [tex]\( 8\pi - 8 \)[/tex] cm².

Answer:

perimeter of the shaded region = 88 +44+28 =160 cm

Step-by-step explanation:

perimeter of shaded region = length AO + arc OB + arc AB

length AO = radius of bigger circle

radius of bigger circle = OX + OB = 2×radius of smaller circle = 2×14 cm = 28 cm

therefore AO = 28 cm

length of arc oB= half of circumference of smaller circle = [tex]\pi[/tex]×14 = 44 cm

length of arc ab = half of circumference of bigger circle  = [tex]\pi[/tex]×28 =[tex]\frac{22}{7}[/tex]×28= 88

therefore perimeter of the shaded region = 88 +44+28 =160 cm

area of the shaded region = half of area of bigger circle - half of area of smaller circle

                                           =[tex]\frac{1}{2} \pi 28^{2} -\frac{1}{2} \pi 14^{2}[/tex]

                                           =[tex]\frac{\pi }{2} (28^{2} -14^{2} )[/tex]

Step-by-step explanation:

Each person will get 1/15 of each watermelon so 3/15 of watermelon that can be simplified to 1/5

Final answer:

Each of the fifteen friends will receive ⅔ of a watermelon when 3 watermelons are shared equally among them.

Explanation:

If fifteen friends want to share 3 watermelons equally, we need to divide the total number of watermelons by the number of friends to find out what fraction of a watermelon each friend will get.

To find the answer, you start with 3 watermelons and divide them by 15 friends, which is:

3 watermelons ÷ 15 friends = ⅔ of a watermelon per friend.

Thus, each friend will get ⅔ of a watermelon.

Answer:

Answer: 12/13

Step-by-step explanation:

In a deck of cards there are 4 of each number. Therefore there are 4 sevens in the deck. 4/52 are 7, but you want the probability of getting a card that IS NOT 7. That means there are 48 cards that aren’t a 7. 48/52 is the probability. But you can simplify this by finding a number that divides evenly into both, which in this case is 4. This simplifies to 12/13.

Answer: 31

Step-by-step explanation: A coefficient is a number that appears in front of a variable. So in this case, since 31 appears in front of the variable y, 31 is the coefficient.

Now, you might think that 7 is a coefficient also but it's not. The reason it's not is because it doesn't have a variable attached to it so a coefficient needs to have a variable next to it.

Answer:

[tex]y-2=-5(x - 2)[/tex]

Step-by-step explanation:

Given:

The equations given are:

[tex]y-2=-5(x - 2)\\X+ 7 = -4(X + 8)\\y - 3 = y(x + 4)\\y + 9 = x(x - 1)[/tex]

Now, a linear function is of the form:

[tex]y=mx+b[/tex]

Where, 'm' and 'b' are real numbers and [tex]m\ne0[/tex]

Equation 1: [tex]y-2=-5(x - 2)[/tex]

Simplifying using distributive property, we get:

[tex]y-2=-5x+10\\y=-5x+10+2\\y=-5x+12[/tex]

The above equation is of the form [tex]y=mx+b[/tex]. So, it represents a linear function.

Equation 2: [tex]X+ 7 = -4(X + 8)[/tex]

Here, both sides of the equation has same variable 'X'. So, it will form an equation of 1 variable. So, it's not a linear function.

Equation 3: [tex]y - 3 = y(x + 4)[/tex]

Simplifying the above equation. This gives,

[tex]y-3=yx+4y\\y-4y-yx=3\\y(1-4-x)=3\\y(-3-x)=3\\y=\frac{3}{(-3-x)}[/tex]

This is not of the form of the linear function. So, it is also not a linear function.

Equation 4: [tex]y + 9 = x(x - 1)[/tex]

Simplifying the above equation. This gives,

[tex]y+9=x^2-x\\y=x^2-x-9[/tex]

This is not of the form of the linear function. So, it is also not a linear function.

7/10

Step-by-step explanation:

3/10+2/5=3/10+4/10=7/10

Answer: 7/10

Step-by-step explanation: To add these two fractions together, we start by finding their common denominator.

The common denominator for 10 and 5 will be the least common multiple of 10 and 5 which is 10.

Since 10 already has a 10 in the denominator, it stays the same.

We multiply top and bottom of our second fraction by 2 and we get 4/10.

Now we are adding like fractions so we simply add across the numerators and keep the same denominator.

So, 3/10 + 4/10 = 7/10.

Therefore, 3/10 + 2/5 = 7/10.

Answer:

56.3 in²

Step-by-step explanation:

Given 2 similar figures with linear ratio = a : b, then

area ratio = a² : b²

Here linear ratio = 4 : 3, thus

area ratio = 4² : 3² = 16 : 9

Let x be the surface area of the smaller can then by proportion

[tex]\frac{16}{100}[/tex] = [tex]\frac{9}{x}[/tex] ( cross- multiply )

16x = 900 ( divide both sides by 16 )

x ≈ 56.3 in² ( to the nearest tenth )

The surface area of the smaller can is approximately 56.3 square inches.

The student's question involves finding the surface area of a smaller can based on its similarity ratio to a larger can. Given that the ratio of the corresponding linear measures of two similar cans is 4:3 and the larger can has a surface area of 100 square inches, we can determine the surface area of the smaller can by using the square of the ratio between their sizes. Since the ratio of their surface areas is the square of their linear dimensions ratio, we can set up the calculation as follows:

[tex](3/4)^2 = x/100,[/tex]

where x represents the surface area of the smaller can. Solving for x:

[tex](3/4)^2 = (9/16) = x/100,[/tex]

x = (9/16) * 100,

x = 56.25.

Therefore, the surface area of the smaller can is approximately 56.3 square inches when rounded to the nearest tenth.

Answer:

The total area of Tony's vegetable garden is 124 square feet

Step-by-step explanation:

The total area of Tony's vegetable garden is composed by three rectangles.

1st rectangle

Length = 10 feet

Width = 6 feet (14 - 8)

Area = 6 * 10 = 60 square feet

2nd and 3rd rectangles are equals

Length = 4 feet

Width = 8 feet (14 - 6)

Area = 2 * 4 * 8 = 2 * 32 = 64 square feet

Total area

Area of the three rectangles

60 + 64 = 124 square feet

The total area of the vegetable garden is 124 ft.

A rectangle is a quadrilateral in which opposite sides are parallel and congruent to each other.

The area of a rectangle is the product of its length and width. It is given by:

Area = length * width

Area of the vegetable garden = (8 ft * 4 ft) + (8 ft * 4 ft) + (10 ft * (14 - 8)ft)

Area of the vegetable garden = 32 ft + 32 ft + 60 ft = 124 ft.

Therefore the total area of the vegetable garden is 124 ft.

Answer:

y = 2x - 3

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = - [tex]\frac{1}{2}[/tex] x - 4 ← is in slope- intercept form

with slope m = - [tex]\frac{1}{2}[/tex]

Given a line with slope m then the slope of a line perpendicular to it is

[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{-\frac{1}{2} }[/tex] = 2, thus

y = 2x + c ← is the partial equation

To find c substitute (3, 3) into the partial equation

3 = 6 + c ⇒ c = 3 - 6 = - 3

y = 2x - 3 ← equation of perpendicular line

The equation of the line passing through (3, 3) and perpendicular to y = -1/2x - 4, is y = 2x - 3.

To find the equation of a straight line passing through the point (3, 3) which is perpendicular to the line y = -1/2x - 4, follow these steps:

Therefore, the equation of the line passing through the point (3, 3) and perpendicular to the line y = -1/2x - 4 is y = 2x - 3.

If an average person listens to music for 1,000 hours in a year, the probability that the component lasts for more than 3 years is 2.3%.

In Mathematics and Statistics, the z-score of a given sample size or data set can be calculated by using the following formula:

Z-score, z = (x - μ)/σ

Where:

σ represents the standard deviation.

x represents the sample score.

μ represents the mean score.

Since an average person listens to music for 1,000 hours in a year, the total life span of the component for 3 years can be calculated as follows;

Total life span = 3 × 1000

Total life span = 3000 years.

By substituting the parameters into the z-score formula, we have the following:

Z-score, z = (3000 - 2400)/300

Z-score, z = 2.0

Based on the standardized normal distribution table, the required probability is given by:

P(X > 3000) = P(x > Z)

P(X > 3000) = 1 - P(Z < 2)

P(X > 3000) = 1 - 0.9773

Probability = 0.0227 × 100.

Probability = 2.27 ≈ 2.3%.
