When a ball is dropped onto a flat floor, it bounces to 65% of the height from which it was dropped. If the ball is dropped from 80 cm, construct a sequence consists of the first, second and third term which represents the height of each bounce from the first drop.
13n
Show that the height of nth bounce, Tn is = 80  .
20
Hence, find the height of the fifth bounce

Answers

Answer 1

Using a geometric sequence, it is found that:

The rule for the height of the nth bounce is:

[tex]a_n = 52(0.65)^{n-1}[/tex]

The height of the fifth bounce is of 9.28 cm.

In a geometric sequence, the quotient between consecutive terms is always the same, called common ratio q.

The nth term of a geometric sequence is given by:

[tex]a_n = a_1q^{n-1}[/tex]

In which [tex]a_1[/tex] is the first term.

In this problem:

Bounces to 65% of the height from which it was dropped, thus the common ratio is of [tex]q = 0.65[/tex].Dropped from 80 cm, thus, the height of the first bounce is [tex]a_1 = 80(0.65) = 52[/tex].

Thus, the rule for the height of the nth bounce is:

[tex]a_n = 52(0.65)^{n-1}[/tex]

The height of the fifth bounce is [tex]a_5[/tex], thus:

[tex]a_5 = 52(0.65)^{5-1} = 9.28[/tex]

The height of the fifth bounce is of 9.28 cm.

Answer:

yes5 × (6 - 3) = (5 × 6) - (5 × 3)

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))

What are similar triangles?

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

Answer:

Step-by-step explanation:

even (2, 4, 6, 8, 10, 12) = 6/12 = 1/2

cube (1, 8) = 2/12 = 1/6     (although all numbers are a cube of something, just not a whole, or even rational, number)

prime (1, 2, 3, 5, 7, 11) = 6/12 = 1/2

Hence, ∠ABD = (3x+6)°

                       = [3(6)+6]°

                       = (18+6)°

Determine whether the inverse of F(x) is a function.

Answers

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.

How are the graphs of the reciprocal functions related to their corresponding original functions? What happens to the graphs of the reciprocal functions as x approaches the zeros of the original functions? Describe how you would teach friends with different learning styles (visual-spatial, aural-auditory, verbal-linguistic, physical-bodily-kinesthetic, logical-mathematical, social-interpersonal, and solitary-intrapersonal) how to graph the reciprocal functions.

Answers

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.
