irst note that 6/8=6/8=9/12, which shows that these are similar triangles. Any of these fractions is the ratio of corresponding sides. Reduce it and find the denominator

Two triangles are known to be similar if the ratio of the similar sides and angles are equal. The value of n, if the two triangles are similar is 3.75

Two triangles are known to be similar if the ratio of the similar sides and angles are equal.

From the given triangles, we have the following

Scale factor  = 3/n

Determine the ratio of the sides

Ratio = 12/15 = 3/n

Cross multiply

12n = 15 * 3
12n = 45

n = 3.75

Hence the value of n, if the two triangles are similar is 3.75

9514 1404 393

Answer:

Step-by-step explanation:

The distributive property tells you the factor outside parentheses multiplies each of the terms inside parentheses.

The difference 6 -3 inside parentheses has two terms, and there is a factor of 5 outside those parentheses. The setup for the distributive property is there, so the distributive property can be used.

__

The outside factor multiplies each inside term. The sign can be left with the inside term, or can be placed between the products.

  5 × (6 - 3) = (5×6) - (5×3)

__

or

  5 × (6 - 3) = (5×6) +(5×(-3))

Answer:

m∠ABD = 24°, m∠CBD = 24°, m∠ABC = 48°

Step-by-step explanation:

3x+6=7x-18

3x-7x=-18-6

   -4x=-24

      x=24÷4

        =6

Hence, ∠ABD = (3x+6)°

                       = [3(6)+6]°

                       = (18+6)°

                       = 24°

Hence, ∠CBD = 24°

Hence, ∠ABC = 24°×2

                       = 48°

Answer:

Answer:

D

Step-by-step explanation:

First, convert 750 meters to centimeters:

75,000cm

Next, take away 150cm from 75,000cm:

74,850cm

The answer is D.

Answer:

  9 cm

Step-by-step explanation:

In a 30°-60°-90° triangle, the ratio of the shortest to the longest sides is 1 : 2.

That means DB = 1/2BC = 3 cm. It also means AB = 2BC = 12 cm.

Then the length of AD is ...

  AD +DB = AB

  AD = AB -DB = 12 cm -3 cm

  AD = 9 cm

Answer:

  B.  3/5

Step-by-step explanation:

The distance from the origin to the point is given by the distance formula:

  d = √((x -0)² +(y -0)²) = √(3² +(-4)²) = √25 = 5

The cosine of the angle is the ratio of x-coordinate to that distance:

  cos(θ) = 3/5

Answer:

f⁻¹(x) is not a function

Step-by-step explanation:

A function can only have one output value per input value. Multiple input values can have the same output value (horizontally), but multiple output values cannot have the same input value (vertically).

For example:

[tex]f(x)=x^2\\f(-2)=-2^2=4\\f(2)=2^2=4[/tex]

This function has 2 inputs with the same output. That is valid.

However, if you take the inverse of that function:

[tex]f^{-1}(x)=\sqrt{x}\\f^{-1}(2)=\sqrt{2}=1.414\\f^{-1}(-2)=\sqrt{-2}=\sqrt{2}i[/tex]

f⁻¹(-2) is an imaginary number. It doesn't exist, and so the inverse of f(x) is still a function because there is no vertical overlap. This is shown more clearly in the attached image.

The graph of the inverse of a function is just mirrored over y = x. This is also shown in the attached image. Any horizontal overlap the function may have becomes vertical overlap, and if those values still exist, the function cannot be a function.

In the function in your question, f(x) has some horizontal overlap around x = 0 and x = 8. If this was mirrored over y = x, the function at x = 8 would have 2 outputs, y = 0 and y = 8. As a result, it cannot be a function.

Let me know if I need to explain any part of that more clearly.

Answer:

43

Step-by-step explanation:

Answer:

Graphs of reciprocal functions reflect against their original functions. For example, y=arcsinx reflects against y=sinx. To graph trigonomoetric functions, simply use a graphing calculator, like Desmos. It's easy. go to Desmos and type y=sinx. It will make a graph for you. Then on a line below the function, type y=arcsinx. You will notice how the inverse of sine reflects against sine. I would teach a visual person by not saying as much and just writing out the equations and using Desmos. To an auditory person, I'd explain as I do the math. I don't know what some of these words mean, but if someone wants a physical example, I'd give them a realistic world problem. I'd ask them to stand up and imagine they are this many feet away from an object that is this many feet tall. We will set up a realistic equation together.
