Give an example of a function that represents a direct variation.

Answers

If y varies in direct proportion to x and y = 6 when x = 2, the variational constant is k = = 3. Consequently, y = 3x is the equation that describes this direct variation.

What is direct variation?

Direct variation is the change in one quantity as a result of the change in another. This suggests that if one quantity rises or falls, the other must rise or fall correspondingly as well.

The formula y = kx is used to answer direct variation questions. If finding the proportionality constant is necessary, the answer is obtained by dividing y by x.

According to the translation rule, The translation of the rectangle is (x, y) → (x – 3, y + 5). Thus option C is correct.

According to the statement

We have to find that the translation rule.

So, For this purpose, we know that the

Translation is refers to the movement of a shape from one point to a different, without altering its appearance.

From the given information:

A rectangle on a coordinate plane is translated 5 units up and 3 units to the left.

With this in mind,

Once there's an upwards or downwards movement, there's a shift within the y coordinate

A move to the left or right movement, the x- coordinate is affected and moving left is negative

Hence,

y-coordinate is positive

x-coordinate is negative

Therefore, the rectangle translating 5 units up and three units to the left would be: (x, y) → (x – 3, y + 5)

So, According to the translation rule, The translation of the rectangle is (x, y) → (x – 3, y + 5). Thus option C is correct.

Answers

The inequality which matches the wingspan of the common sparrow is :

9 ≤ x ≤ 15.

What is inequality and how can we frame one?

Inequalities are the equations in which two non equal expressions are compared using the  mathematical relations such as ≤(less than or equal to ), ≥ (more than or equal to ), < (less than ) , >( more than).

Given that the common sparrow has a wingspan of 9 to 15 centimeters.

Let the wingspan of sparrow be x then given that x is more than or equal to  9  which gives an inequality :  x ≥ 9   ....(1)

Also it is given that wingspan, x is not more than 15 centimeters which means x is less than or equal to 15 and this gives an inequality: x ≤ 15   ....(2)

Combining (1) and (2), we get:

9≤ x ≤ 15

Give an example of a sequence that is not an arithmetic sequence.

Answers

The sequence 2, 3, 5, 6..is example of the sequence which is not in arithmetic sequence AP.

What is the AP sequence (arithmetic progression)?

In Arithmetic Progression (AP), the distinction between two arithmetical orders is a constant. It is also known as Arithmetic Sequence.

Then we'd run into some important words in AP, such as:

The first term (a)Common difference (d)Term nth (an)The total of first n terms (Sn)

The AP can also be described using common distinctions, as shown below.

The following is the way to determine an AP's n-th term: an = a + (n − 1) × dThe formula for arithmetic progression sum is as follows: Sn = n/2[2a + (n − 1) × d].Common difference 'd' is d = a2 - a1 = a3 - a2 = a4 - a3 = ......      = an - an-1.

Now, as per the question;

Consider any sequence. Let's say  2, 3, 5, 6..

Let's consider the first term is'a₁' = 2.

Let's consider 'a₂' = 3 is the second term.

Let's consider the third term is 'a₃' = 5.

Let's consider the fourth term be 'a₄' = 6

d₁  = a₂ - a₁      

Substitute the values;

d₁  = 3 - 2 = 1       ........(equation 1)

Now take the other set;

d₂  = a₃ - a₂    

d₂  = 5 - 3 = 2     .......(equation 2)

From the two equations 1 and 2. it is clear that the value of both common difference d₁ is not equal to d₂. Thus, the sequence considered is not in AP.

Therefore, the considered sequence 2, 3, 5, 6.. is not in AP.

What is the absolute value function?

The absolute value function is defined by the following piecewise rule, depending on the input of the function:

|x| = x, x ≥ 0.|x| = -x, x < 0.

It measures the distance of a point x to the origin, hence, for example, |-2| = |2| = 0.

In general terms, we have that:

|f(x)| = f(x), f(x) ≥ 0.|f(x)| = -f(x), f(x) < 0.

Then, for item b, we have that:

|2x + 1| = 2x + 1, x ≥ -0.5.|2x + 1| = -2x - 1, x < -0.5.

Then:

y = -3x - 1, x < -0.5.y = x - 1, x ≥ -0.5.

The function breaks at x = -0.5.

For item c, we have that:

|2x - 1| = 2x - 1, x ≥ 0.5.|2x - 1| = -2x + 1, x < 0.5.|x + 3| = x + 3, x ≥ -3.|x + 3| = -x - 3, x < -3.

Then:

y = -2x - 2, x < -3.y = 4, -3 ≤ x ≤ 0.5.y = 4x + 2, x > 0.5.

The function breaks x = -3 and x = 0.5.

For item d, we have that:

|x + 1| = x + 1, x ≥ -1.|x + 1| = -x - 1, x < -1.

Hence:

y = -2x - 2,  x < -1.y = 2x + 2, x ≥ -1.

Determine whether the regular polygon will tessellate in the plane. Write yes or no. Explain.
16 -gon

Answers

No, he regular polygon 16 -gon will not tessellate in the plane.

What is tessellation?

A tessellation or tiling is the seamless application of one or more geometric shapes, known as tiles, to a surface, frequently a plane. Tessellation in mathematics can be expanded to include other geometries and higher dimensions.

A tiling constructed of materials like cemented ceramic hexagons or squares is referred to as a real-world tessellation. Such tilings may be ornamental designs or serve practical purposes such providing long-lasting and water-resistant pavement, floor, or wall coverings.

Tessellations were historically employed in Islamic art, such as the Moroccan architecture and the ornamental geometric tiling of the Alhambra palace. They were also used in Ancient Rome.

Regular polygons tessellate if their interior angles divide by 360° evenly or if the total of their interior angles is a factor of 360°. A tessellation is a pattern made of identical forms that fit together seamlessly.

So lets find out how pentagon won't tessellate.

First we find the measure of the interior angles of 16 -gon,

[tex]\frac{2520\°}{16} = 157.5\°[/tex]

Now divide the interior angle by 360°

[tex]\frac{360\°}{157.5\°} = 2.28[/tex]

Hence, the measure of the interior angle does not divide by 360°.

Therefore, we conclude that the regular polygon 16- gon will not tessellate in the plane.

Dominic rented a car for the weekend. When he started driving on the highway he noticed the odometer had already logged 18,115 miles. After 45 minutes of highway driving, the odometer read 18,169 miles.

If he drove on the highway a total of four hours and traveled at a constant speed that entire time, what did the odometer read when he exited the highway?

Answers

The reading in the odometer will be 18,403 miles after travelling for 4 hours on the highway as Dominic covered a distance of 288 miles on the highway.

Distance on the odometer that was already logged = 18,115 miles.

Distance on the odometer after 45 minutes = 18,169 miles.

Distance covered in 45 mins = 18169 - 18115 = 54 miles.

Speed = 54 miles / 45 min

Speed = 6 miles / 5 minutes = 72 miles / hour

Now, he drove on the highway for 4 hours.

Time = 4 h

Distance = speed × time

D = 72 × 4 miles

D = 288 miles

Reading on the odometer when he exited the highway will be:

R = 18115 + 288 miles

R = 18403 miles.

Therefore, we get that, the reading in the odometer will be 18,403 miles after travelling for 4 hours on the highway as Dominic covered a distance of 288 miles on the highway.

Write the equation of the line in slope-intercept form.
y-5x=16

Answers

The equation of the line in slope-intercept form is y = 5x + 16 .

The equation of a line in slope-intercept form can be written as follows,

y = mx + c                                                       equation 1

m in the above equation represents slope of the line and c represents the intercept.

The given equation is y - 5x = 16 .

To get the equation of the line in slope-intercept form we need to convert the given equation in the format of equation of a straight line i.e., equation1. So, now we will rearrange the given equation as

y - 5x = 16

On adding 5x on both sides in above equation, we will get

y = 5x + 16                                                   equation 2

On equating equation 1  and equation 2, we will get
