slope formula  can be illustrated  as ,  (y₂ - y₁) / (x₂ - x₁)

It is given in question that-

x₁ = -1 and y₁ = 1

x₂ = -2and y₂ = -3

so by using given formula for slope

slope= (y₂ - y₁) / (x₂ - x₁)

slope = (-3- (1) / (-2 - (-1) = (-3 - 1) / (-2 + 1) = -4/-1 = 4

final answer , slope =4

What is slope ?

The ratio of how much y grows as x grows by a certain amount is known as a line's slope. The slope of a line indicates how steep it is, or how much y rises as x rises. Anywhere along the line, the slope remains constant (the same).

Answer:

[tex] \sf \: slope(m) = 4[/tex]

Step-by-step explanation:

Now we have to,

→ find the required slope.

Formula we use,

→ Slope(m) = (y2 - y1)/(x2 - x1)

Then the slope will be,

→ m = (y2 - y1)/(x2 - x1)

→ m = (-3 - 1)/(-2 -(-1))

→ m = (-4)/(-2 + 1)

→ m = (-4)/(-1)

→ m = 4/1

→ [ m = 4 ]

Hence, the slope is 4.

The possible value of other two angles will be 20 degree.

What are the types of triangle?

Basically, there are six different types of triangles in terms of lengths and measurements of triangle lines or angles. The sum of all interior angles of a triangle is always 180 degrees. This is called the angular summation of the triangle. Depending on the length of the sides, triangles can be divided into three types:

scale

Isosceles

equilateral

It is given that an isosceles triangle has an angle that measures 140°

We know that two sides of isosceles triangle are equal and by the property of triangle we know that angle opposite to equal sides are equal therefore remaning two angles of isosceles triangle will be equal.

Let the angles be x

By angle sum property of triangle

x + x + 140 = 180

2x = 180 - 140

2x = 40

x = 40/2 = 20

Therefore, the possible value of other two angles will be 20 degree.

The critical numbers of the function are; θ = π/6, 5π/6

We are given the trigonometric function as;

Let us find the first derivative;

f'(θ) = 6(-sin θ/cos² θ) + 3(1/cos² θ)

f'(θ) = (3 - 6sin θ)/cos² θ

At f'(θ) = 0, we have;

Answer:

The current price of sofa is $195.50.

Step by Step explanation:Cost price of the sofa for the store = $200

Now, the store marked it up 15%.

So, marked price of sofa = $200 + 15% of $200

=200 + 30

=$230

Now, it is given that the sofa could not sell at this price. So, the store reduces its price by 15% now.

So, current price of sofa = $230 - 15% of $230

= 230 - 34.5

=$195.5

So, the current price of the sofa is $195.50.

A probability is a numerical representation of the likelihood or chance that a specific event will take place.

12% of peanut M&M’s = brown

15% = yellow

12% = red

23% = blue

23% = orange

15% = green

Here, Probability of an event is represented as P

a) P(not green) = 100% - 15%

                        = 85%

                        = 0.85

b) P(yellow or red) = 15% + 12%

Answer:

$27.69

Step-by-step explanation:

The correct answer is A.

500 is the size of the population at the moment of maximum growth.

Given data:

To find the size of the population at the moment when the population is growing most rapidly, we need to determine the maximum value of the derivative dP/dt.

Given the logistic differential equation [tex]\frac{dP}{dt} = (\frac{1}{10})P - (\frac{1}{5000})P^2[/tex], find the derivative by taking the derivative of each term separately:

[tex]\frac{dP}{dt} = (\frac{1}{10})P - (\frac{1}{5000})P^2[/tex]

To find the critical points where the derivative is zero or undefined, set dP/dt equal to zero:

[tex](\frac{1}{10})P - (\frac{1}{5000})P^2=0[/tex]

Simplifying:

[tex](\frac{1}{10})P= (\frac{1}{5000})P^2[/tex]

[tex]10P^2=5000P[/tex]

Dividing both sides by P and rearranging:

[tex]10P(P-500)=0[/tex]

This equation has two solutions: P = 0 and P = 500.

To determine which solution corresponds to the moment when the population is growing most rapidly, examine the second derivative. Taking the second derivative of the logistic differential equation, we have:

[tex]\frac{d^2P}{dt^2} = \frac{1}{10} - \frac{2}{5000}P[/tex]

Evaluating the second derivative at P = 0 and P = 500, we get:

[tex]\frac{d^2P}{dt^2}_{P=0} = \frac{1}{10} - \frac{2}{5000}(0)[/tex]

[tex]\frac{d^2P}{dt^2}_{P=0}= \frac{1}{10} > 0[/tex]

[tex]\frac{d^2P}{dt^2}_{P=500} = \frac{1}{10} - \frac{2}{5000}(500)[/tex]

[tex]\frac{d^2P}{dt^2}_{P=0}= -\frac{1}{10} < 0[/tex]

Since the second derivative is positive at P = 0 and negative at P = 500, the moment when the population is growing most rapidly occurs at P = 500.

Hence, the size of the population at the moment when the population is growing most rapidly is 500.

Answer:

When factoring, you want to get all of the terms on one side first and set all of it equal to 0. Many of the problems here are already in this format =0, but there are some where you'll have to move the terms around.

In these examples, it also looks like the highest power you have is x^2. This makes things easier to work with.

Let's just start with the first one, x^2 - 9x + 18 = 0.

We need to find two numbers that multiply to give us 18, and add together to give us -9. That would be -6 and -3.

-6 + -3 = -9

- 6 * -3 = 18

We can rewrite it now. This is the factored form.

(x - 6) * (x - 3) = 0

If you want to, you can go back to expanded form using the acronym 'FOIL'. First, Outside, Inside, Last. This refers to the order of multiplying the terms.

(x - 6) * (x - 3)

x * x = x^2

x * -3 = -3x

-6 * x = -6x

-6 * -3 = 18

Simplify

x^2 - 3x - 6x + 18 = 0

And we're back to where we started.

x^2 - 9x + 18 = 0

Hope this helps.

[tex]\huge\boxed{\sf v = 0.4\ mph}[/tex]

Step-by-step explanation:

Speed = v = ?

v = S/t

v = 0.2/0.5

[tex]\rule[225]{225}{2}[/tex]

Answer: 8/5 mph

Step-by-step explanation:

According to definition, an object's speed is determined by:

s=d/t where,

d is the object's travel distance, and t is the amount of time it takes.

We can replace these values with:

Since, s= (4/5) / (1/2) mph

=> s= 8/5 mph

The object's speed to cover 4/5 miles in 30 minutes is: 8/5 mph

The spreadsheet formula that would correctly calculate the average (mean) of the given values is: (25 + 50 + 75) / 3 = 50.

An average is a single number taken as representative of a list of numbers, generally the sum of the numbers divided by how many numbers are in the list (the arithmetic mean).

The formula to calculate the average of given numbers is equal to the sum of all the values divided by the total number of values. Average = Sum of Values / Number of Values.

So, in this case:

Values: 25, 50, 75

Number of Values: 3

Thus, the average:

Sum of Values / Number of Values = (25 + 50 + 75) / 3 = 50
