The speed limit in Canada is 100km/hr. What is the value of this limit in mi/hr given 1mi = 1.609km?

Step-by-step explanation:

we have no continuous curve here, the supposed function only consists of a few data pair points. and that is absolutely ok.

any function just maps a set of x (input) values to a set of y (function result) values.

A.

yes, it is a function, because every "used" x value has exactly 1 assigned y value.

when we draw a vertical line and move it across the grid, there are never 2 or more of the points in the line. always only one.

the opposite (every y value has exactly 1 x value as origin) is NOT necessary to be a function. but it would have to be true for the inverse function to be a function too.

B.

the domain is the interval or set of all valid x values.

since we have only single points, it is a set here :

{-4, -3, -2, 0, 2, 3}

C.

the range is the interval or set of all valid y values :

{-3, -1, 0, 2, 3}

D.

as we can see on the chart, the only point with x value = 2 has the y value = -3.

so,

y = -3 when x = 2

or formally

f(2) = -3

Answer:

x = 4

Step-by-step explanation:

Perimeter of triangle: P = (5x -1) + (5x -1) + (2.2x + 10)

Perimeter of square: P = 4(6.5x - 11.8)

so (5x -1) + (5x -1) + (2.2x + 10) = 4(6.5x - 11.8)

5x - 1 + 5x - 1 + 2.2x + 10 = 26x - 47.2

12.2x + 8 = 26x - 47.2

26x - 12.2x = 8 + 47.2

13.8x = 55.2

x = 55.2/13.8 = 4

In the counting of numbers from 2 to 99, the digit 9 appears 20 times.

To identify how many times the digit 9 appears, we can first list the numbers we know have a 9 in them:

9, 19, 29, 39, 49, 59, 69, 79, 89, 99

Although we've identified these numbers, we are not finished. Numbers in the 90s also qualify as digits of 9. Therefore, these numbers also are included:

91, 92, 93, 94, 95, 96, 97, 98

Now that we have all the numbers from 1 to 99 with the digit 9 in them, we can count up how many numbers there are with consideration that the number 99 also has two digits of 9 in it:

[(10 + 8) + 2] = 20

Hence, the digit 9 appears 20 times in the counting numbers from 1 to 99.

Answer:

There are 20 times the digit 9 appears in counting numbers from 1 to 99.

Step-by-step explanation:

To see why this is the case, we can break the counting numbers down into two categories: numbers with a 9 in the units place and numbers without a 9 in the units place.

For the first category, we can count the number of times a 9 appears in the units place by counting from 9 to 99 in increments of 10. There are 10 numbers in this category.

For the second category, we can count the number of times a 9 appears in the tens place by counting from 19 to 99 in increments of 100. There are 10 numbers in this category as well.

Therefore, the total number of times the digit 9 appears in counting numbers from 1 to 99 is 20 times.

The amount spent on pants based on the information illustrated is 45 soles.

Let the amount spent of shirt = x

Amount spent on sweaters = 2x

Amount spent on pants = 3x

Amount spent = 90

Therefore, the value will be:

x + 2x + 3x = 90

6x = 90

Divide

x = 90/6

x = 15

Therefore, the amount spent on pants will be:

= 3x

= 3 × $15

The equation of the plane that goes through these points is:

6x + 2y + z = 10.

The equation of the plane is found replacing the points into the following equation:

ax + by + c = z.

For point A, we have that:

3b + c = 4.

For point B, we have that:

a + 2b + c = 0.

For point C, we have that:

-a + 6b + c = 4.

Hence the system is:

From the first equation, we have that:

c = 4 - 3b.

Replacing in the second, we have that:

a + 2b + 4 - 3b = 0

a - b = -4.

Replacing in the third, we have that:

-a + 6b + 4 - 3b = 4.

-a + 3b = 0.

a = 3b.

We have that a - b = -4, hence:

3b - b = -4

2b = -4

b = -2.

a = 3b, hence a = -6.

c = 4 - 3b -> c = 10.

Hence the equation is:

ax + by + c = z.

z = -6x - 2y + 10

6x + 2y + z = 10.

Step-by-step explanation:

state 3 fractors other than $/ hours

Step-by-step explanation:

a) right - 1 unit; up - 3 units; angle between branches is decreased. All the details are in the attachment;

b) the required graph is in the attachment.

The measures of the angles are:

m<7 = 47°

m<8 = 62°

m<1 = 62°

m<2 = 71° [vertical angles theorem]

m<5 = 109°

m<3 = 109°

m<4 = 35°

m<6 = 29°

The alternate interior angles theorem states that two interior angles that are formed along a transversal and lie alternate to each other on two parallel lines are congruent to each other.

Measure of angle 7 = 47° [based on the alternate interior angles theorem]

Measure of angle 8 = 180 - 47 - 71 [triangle sum theorem]

Measure of angle 8 = 62°

Measure of angle 1 = measure of angle 8 = 62° [based on the alternate interior angles theorem]

Measure of angle 1 = 62°

Measure of angle 2 = 71° [vertical angles theorem]

Measure of angle 5 = 180 - 71 [linear angle theorem]

Measure of angle 5 = 109°

Measure of angle 3 = measure of angle 5 = 109° [vertical angles theorem]

Measure of angle 4 = 180 - measure of angle 3 - 36 [linear angle theorem]

Measure of angle 4 = 180 - 109 - 36

Measure of angle 4 = 35°

Measure of angle 6 = 180 - measure of angle 5 - 42 [linear angle theorem]

Measure of angle 6 = 180 - 109 - 42

Measure of angle 6 = 29°

The translated vertices of the rhombus are: K(-1,-3), L(3,-1), M(1,-5) and N(-3,-7)

The rhombus is a parallelogram which has all sides equal. the diagonals of a rhombus bisect at right angles. the difference between a rhombus and a square is that none of the angles of a rhombus are 90°.

To translate a figure with given co-ordinates into another figure with a particular translation we simply add or subtract the given values from the coordinates of the available points.

Given co-ordinates of Rhombus are K(-3, 2),L(1, 4),M(-1 ,0)and N(-5, -2).

The translation is given as (x,y) → (x+2, y-5)

So we calculate the coordinates as:

The translated co-ordinate  K(-3, 2)→ K'(-1,-3)

The translated co-ordinate  L(1, 4)→  L'(3,-1)

The translated co-ordinate  M(-1 ,0)→ M'(1,-5)

The translated co-ordinate N(-5, -2)→ N'(-3,-7)

A possible solution for this case of collinear points is (x, AB, BC, CD, AC, AD) = (0, 18, 14, 10, 32, 42).  

In this question we have four points that are collinear, that is, that lie on the same line. Mathematically, speaking we have the following equations representing the geometric system:

BC = 14 + x             (1)

AD = 42 + x           (2)

AC = x + 32           (3)        

By (1) and (3):

AB = (x + 32) - (14 + x)

AB = 18

By (2) and (3):

CD = (42 + x) - (x + 32)

CD = 10

According to the solving the beginning value of retained earnings:

= $1,60,000.

Retained earnings are usually included in the shareholders' equity portion of a company's balance sheet. Retained earnings are computed by adding beginning-period retained earnings to net income (or loss), then deducting dividend distributions.

To calculate retained earnings, subtract a company's liabilities from its assets to obtain stockholder equity, then locate the common stock line item on your balance sheet and multiply the total stockholder equity by the common stock financial statement figure (if the only two items in your stockholder equity were also common stock).

Retained earnings, ending = $240,000.

Net income = $110,000.

Preferred stock dividend = $30,000.

Retained earning, beginning = ?

Retained earnings, ending = Retained earning, beginning + Net income - Preferred stock dividend

$240,000 = Retained earning, beginning + 110,000 - 30,000

Retained earning, beginning = 1,60,000

a translation of 4 units right means add 4 to the x- coordinate, that is

W (- 2, 4 ) → W' (- 2 + 4, 4 ) → W' (2, 4 )

The compliment of set A that is A' is equal to {2, 4, 8, 12, 16}.

We are given the universal set as:

U = {2, 4, 6, 8, 10, 12, 14, 16}

We are also given that set A is:

A = {6, 10, 14}

We need to find A'

For this, we will subtract set A from the universal set, U.

So, we get that:

A' = U - A

A' = {2, 4, 6, 8, 10, 12, 14, 16} - {6, 10, 14}

Solving the expression, we get that:
