Consider the function y=-2-cos(x-pi). What effect does pi have on the basic graph?

1 answer:

8 0

Using translation concepts, it is found that pi is the phase shift of the graph, and since it is negative, the graph is shifted right pi units.

<h3>What is a translation?</h3>

A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction either in it’s definition or in it’s domain. Examples are shift left/right or bottom/up, vertical or horizontal stretching or compression, and reflections over the x-axis or the y-axis.

In this problem, the change is given as follows:

x -> x - pi

It means that the change is in the domain, in which pi is the phase shift of the graph, and since it is negative, the graph is shifted right pi units.

On a recent day 8 euros were worth 9 dollars and 24 euros were worth 24 dollars write an equation of the form y = kx

slavikrds [6]

<h3><u>Question:</u></h3>

On a recent day, 8 euros were worth $9 and 24 euros were worth $27. Write an equation of the form y = kx to show the relationship between the number of euros and the value in dollars.

<h3><u>Answer:</u></h3>

y = 1.125x is the equation to show the relationship between the number of euros and the value in dollars.

<h3><u>Solution:</u></h3>

Given that On a recent day 8 euros were worth 9 dollars and 24 euros were worth 24 dollars

Let "y" be the value in dollars

Let "x" be the number of euros

We have to write a equation in form of y = kx

<em><u>8 euros were worth 9 dollars</u></em>

"k" is found as follows:

$k = \frac{\text{value in dollars}}{\text{number of dollars}}$

$k = \frac{9}{8}$

Therefore, equation of y = kx is given as:

$y = \frac{9}{8}x$

$y = 1.125x$

To check the equation, use the another given value

24 euros were worth $27

$y = 1.125 \times 24\\\\y = 27$

Hence the equation y = 1.125x is correct

The force, F (Newtons), between two objects is inversely proportional to the square of the distance, d (metres), between them. T

Anarel [89]

Answer:

$D = 0.42m$

Step-by-step explanation:

Given

Force = 0.052 N when Distance = 1.6 m

Required

Find Force; when distance = 0.74 N

The question says force is inversely proportional to square of distance;

Let F represent Force and D represent Distance;

Mathematically;

$F\alpha \frac{1}{D^2}$

Convert proportion to equation

$F = \frac{k}{D^2}$

<em>Where k is the proportionality constant; This means that k is always constant</em>

Make k the subject of formula

$F * D^2 = \frac{k}{D^2} * D^2$

$FD^2 = k$

When F = 0.052 and D = 1.6; the value of k is as follows

$0.052 * 1.6^2 = k$

$0.13312 = k$

$k = 0.13312$

When F = 0.74;

Recall that k is always constant; so $k = 0.13312$

To solve for D, we'll make use of $F = \frac{k}{D^2}$

Substitute $k = 0.13312$ and F = 0.74;

$0.74 = \frac{0.13312}{D^2}$

Multiply both sides by D²

$0.74 * D^2 = \frac{0.13312}{D^2} *D^2$

$0.74 * D^2 = 0.13312$

Divide both sides by 0.74

$\frac{0.74 * D^2}{0.74} = \frac{0.13312}{0.74}$

$D^2 = \frac{0.13312}{0.74}$

$D^2 = 0.17989189189$

Take square roots of both sides

$D = \sqrt{0.17989189189}$

$D = 0.42413664294$

$D = 0.42m$ (Approximated)
