A penguin walks south. it completes the first 1/3 mile in 1/5 hour and continues walking at the same rate. what is the penguin's speed in miles per hour?

The mean score in the fifth game that will allow you to advance is 73.

The mean score in the fifth game that will allow you to advance can be gotten this way:

Assign the mean score, the variable, and x.

Compute the scores with remarks as follows:

95 + 91 + 77 + 89 + x  ≥ 85

              5

352 + x ≥ 85

      5

85 × 5 = 425

352 + x ≥ 425

x = 425 - 352

x = 73.

So, the score in the fifth game that will allow you to advance will be 73.

Answer: a= 3b + 4c -8

Step-by-step explanation:

a= 3b + 4c -8

-2a + 6b = -8c + 16

-6b from the left the isolate a

-2a = -6b - 8c + 16

then divide by -2 to cancel it out

a = 3b + 4c -8

The equation is equivalent to -2a + 6b = -8c + 16 will be a= 3b + 4c -8

A linear equation is an equation that has the variable of the highest power of 1. The standard form of a linear equation is of the form Ax + B = 0.

We are given the linear equation;

a= 3b + 4c -8

-2a + 6b = -8c + 16

-6b from the left the isolate a

-2a = -6b - 8c + 16

Then divide by -2 to cancel it out;

a = 3b + 4c -8

The equation of the required line is y = - 2x + 11

We need to find the equation of the line parallel to the given line y = -2x + 5 that contains C(4, 3)

Let m be the slope of the required line.

The slope of the line y = -2x + 5 is -2

We know that, the slope of the parallel lines is equal.

So, m = -2

The required line contains point C(4, 3)

Using point-slope form the equation of the line would be,

(y - y1) = m(x - x1)

y - 3 = -2(x - 4)

y - 3 = -2x + 8

y = -2x + 8 + 3

y = -2x + 11

Pretty simple, basic algebra.

1. Switch the sides to make it easier to read

2. Subtract 3 on both sides

3. Divide both sides by 8 to cancel the denominator

4. Divide both sides by 7 to isolate the y

Based on the points given for the line in the table, the equation in slope intercept form is y = -1/2 + 1

To find the equation of a line, you first need to find the slope of the line as:

= Change in y / Change in x

= (0 - 1) / (2 - 0)

= -1 / 2

= - 1/2

Using the slope, find the y-intercept:

y = slope(x) + y-intercept

0 = -1/2(2) + y-intercept

y-intercept = 0 + 1

y-intercept = 1

The image of triangle CDE after a rotation of 90º counterclockwise around the origin is graphed at the end of the answer.

When a polygon undergoes a rotation, this rotation is over an angle measure, that defines the coordinate rule for each vertex of the polygon.

For triangle CDE, the vertices are given as follows:

D(-7,-1), C(-7,-7), E(-4,-8).

The rule for a rotation of 90º counterclockwise around the origin, for each vertex (x,y) of the polygon, is given by:

(x,y) -> (-y,x).

Hence, applying the rule above, the vertices of the image of triangle CDE will be given as follows:

D'(1,-7), C'(7,-7), E'(8,-4).

The triangle, with these vertices labeled, is graphed at the end of the answer.

The coordinates of the image of point D are (- 6, - 4) and a representation  of the rigid transformation is shown in the picture attached below.

Herein we find the location of point D, which is set on Cartesian plane and must be modified by the use of a rigid transformation known as dilation. The general definition of the dilation rule is defined below:

D'(x, y) = O(x, y) + k · [D(x, y) - O(x, y)]

Where:

If we know that O(x, y) = (0, 0), D(x, y) = (- 3, - 2) and k = 2, then the coordinates of the image are:

D'(x, y) = (0, 0) + 2 · [(- 3, - 2) - (0, 0)]

D'(x, y) = (- 6, - 4)

The number of centers that will be needed to contain the guests is 5.

It should be noted that the question isn't well written but will be answered based on the information given.

From the information, a space center can have at most 7 guests and there are 31 guests. In this case, the number of space centers needed will be calculated by dividing the number of guests by the numbers that are contained in each center.

This will be:

= Number of guests / Number contained by each center

= 31 / 7

= 4 3/7

In this case, since there's a remainder of 3, this implies that we will need an extra space center. Therefore,the total space centre will be:

= 4 + 1

= 5

Using linear functions, it is found that:

A linear function, in slope-intercept format, is modeled according to the following rule:

y = mx + b

In which:

In the context of this problem, it is used because the rate of change for each plan is constant, that is, for each device, there is a constant increase in the plan charge.

For the plans in this problem, we have that:

Hence the models for each plan are given as follows, with P representing the number of devices.

The costs will be the same when:

F(P) = M(P)

Hence we solve for P to find the number of plans as follows:

Given the transformations of the graph of f(x)=6x, the function rule g(x) is therefore g(x) = -1/2x.

A point, line, or geometric figure can be transformed in one of four ways, each of which affects the shape and/or location of the object. Pre-Image refers to the object's initial shape, and Image, after transformation, refers to the object's ultimate shape and location. Transformations can be divided into four categories: translation, rotation, reflection, and enlargement. You must be able to carry out each transformation and recognize which ones have already been done.

Given Data

f(x) = 6x

The resulting function will be f(x) = -6x if the function is not reflected over the x-axis.

The final function rule will be; if the resulting function is compressed by a factor of 1/12.

g(x) = 1/12(-6x)

g(x) = -1/2x

The common difference of the AP is 4.33 and its first term is 30.

The formula to calculate the nth term of an Arithmetic Sequence is -

a - first term of A.P.

d - Common difference of A.P.

n - position of term

Given is the 1st term of an AP as 30 while the Sum of the its first 7 terms is 56.

We have -

[a] = 30

and -

a + (7 - 1)d = 56

30 + (6)d = 56

6d = 56 - 30

6d = 26

d = 26/6

d = 13/3

d = 4.33

and

the first term of the AP is 30.

Therefore, the common difference of the AP is 4.33 and its first term is 30.
