Write the equation of the line that passes
through the points (-7,-9) and (-3,-1)

Answers

Answer 1

Answer:

2x + 5

Step-by-step explanation:

I am assuming you are talking about a linear function. If it is, then the equation would be:

2x + 5.

Hope this helps!

Answer 2

Answer:

[tex]y = 2x + 5[/tex]

Step-by-step explanation:

For this example, I used the slope-intercept form, [tex]y = mx + b[/tex], where m represents the slope and b represents the y-intercept.

In order to find the equation, we must find the slope and y-intercept.

Finding m

The slope can be found with the formula:

[tex]m = \frac{y_{2} - y_{1}}{x_{2} - x_{1}}[/tex], where the x and y variables represent different x and y values from the given points.

Substituting in values from the points, we get:

[tex]m = \frac{-1 + 9}{-3 + 7}\\\\m = \frac{8}{4}\\\\m = 2[/tex]

Finding b

In order to find the y-intercept, we must substitute the slope back into the original equation:

[tex]y = 2x + b[/tex]

After this, we must also substitute either of the two points. Both will give the correct answer, but (-3, -1) will be used for this example.

[tex]-1 = 2(-3) + b\\-1 = -6 + b\\5 = b[/tex]

Finding the equation

After this, all that must be done is to substitute the values for b and m back into the original equation.

[tex]y = 2x + 5[/tex]

To check our work, we can substitute in either of the given points. For demonstration purposes, (-7, -9) will be used.

[tex](-9) = 2(-7) + 5\\-9 = -14 + 5\\-9 = -9[/tex]

Leave answer in terms of n
A. 75 pi units squared
B. 100 pi units squared

Answers

Answer:

B. 100 pi units squared

Step-by-step explanation:

Find the surface area of a sphere with radius 5 using the formula SA=4pir²

Leave answer in terms of π = pi

From the question

The formula for the Surface Area if a square = 4 × pi × r²

r = 5

Hence,

Surface Area of a Sphere = 4 × pi × 5²

= 100 pi units squared

Option B is the correct option

What is length of BW using what you know? DONT GIVE ME A LINK JUST ANSWE PLEASEE (will give brainlist)

Answers

Answer:

The length of BW is [tex]105\sqrt{2}[/tex], or about 148.49.

Step-by-step explanation:

For this problem, we will assume that the figure is a square. We will call the figure "Figure BOWL".

Because figure BOWL is a square, we know that the lengths of each sides of the square are equal, so the length of each side is 105.

Notice that the BW, OB, and WO make a triangle. We'll call it triangle BOW. Since figure BOWL is a square, we know that angle BOW is 90°, and so triangle BOW is a right triangle.

Since triangle BOW is a right triangle, we can solve for BW using the Pythagorean theorem, [tex]a^{2} + b^2 = c^2[/tex]. "a" and "b" are the legs of the triangle, while "c" is the hypotenuse of the triangle.

In triangle BOW, the legs are OB and WO, while the hypotenuse is BW.

Plug in the values for the equation and solve.

[tex]a^2 + b^2 = c^2[/tex]

[tex]OB^2 + WO^2 = BW^2[/tex]

[tex]105^2 + 105^2 = BW^2[/tex]

[tex]11,025 + 11,025 = BW^2[/tex]

[tex]22,050 = BW^2[/tex]

[tex]\sqrt{22,050} = BW[/tex]

We can either use the estimated value, or the exact simplified value of [tex]\sqrt{22,050}[/tex].

Here is the exact simplified value:

[tex]\sqrt{22,050} = \sqrt{25 * 882} = \sqrt{25 * 9 * 98} = \sqrt{25 * 9 * 49 * 2} = \sqrt{5^2 * 3^2 * 7^2 * 2} = (5 * 3 * 7)\sqrt{2} = 105\sqrt{2}[/tex]

BW = [tex]105\sqrt{2}[/tex]

For the estimated value, just use a calculator:

[tex]\sqrt{22,050}[/tex] ≈ 148.49

BW ≈ 148.49

The mean of a data set is 124. The mean absolute deviation is 38. What is the greatest possible number within the mean absolute deviation?

Answers

Answer:

Infinity

Step-by-step explanation:

The given parameters are;

The mean of the data, μ = 124

The mean absolute deviation = 38

The mean absolute deviation is given as follows;

[tex]Mean \ absolute \ deviation = \dfrac{\sum \left | X - \mu \right |}{N} = 38[/tex]

Where;

μ = Mean

X = Score

N = The number of scores

Therefore;

[tex]N \times 38 = \sum\limits_{i = 1}^N \left | X - \mu \right |} = \sum\limits_{i = 1}^N \left | X -124 \right |}[/tex]

When there are an infinite number of terms, N = ∞, the greatest possible number within the mean absolute deviation is therefore also infinite

[tex]\infty \times 38 = \sum\limits_{i = 1}^{\infty} \left | X - \mu \right |} = \infty[/tex]

[tex]Greatest \ possible \ value \ for \left | X - \mu \right |} = \infty[/tex]

10. The perimeter of the rectangle below is 30 inches. Find the value of x.
5x
X-3

Answers

The answer is 3. This is because the perimeter is 30 so 5x+5x+x-3+x-3 = 30. Thus you have 12x-6=30 so x = 3

Using the perimeter formula of the rectangle, the value of x is 3 inches.

What exactly are rectangles?In the Euclidean plane, a rectangle is a quadrilateral with four right angles.A parallelogram with a right angle or an equiangular quadrilateral, where equiangular means that all of its angles are equal, are other ways to define it.A rectangle with four equal-length sides is a square.Rectangles are enclosed 2-D shapes with four sides, four corners, and four right angles.Equal and parallel opposite sides make up a rectangle.

So, the value of x will be:

The formula for the perimeter of the rectangle: 2(l+b)

Now, put the values in the formula and calculate x as follows:

2(l+b) = 302(5x+x-3) = 3010x + 2x -6 = 3012x - 6 = 3012x = 30+612x = 36x = 36/12x = 3

Therefore, using the perimeter formula of the rectangle, the value of x is 3 inches.
