8 weeks the coat would cost 150 * (1-0.15+ = 127.50

9 week it would cost 127.50 *(1-0.05) = 121.13

10 week = 121.13 * (1-0.05) = 115.07

 week 11 = 115.05 * (1-0.05) = 109.32

he can buy it in week 11, because it would be less than 110 and the sore would still make a profit, because it costs more than 100

The correct answer is A. Crossing the street.

Explanation

Being an observer refers to observing or looking at every detail of the surrounding environment or situation. This implies when you are an observer you understand a situation by noticing and understanding every detail. In this task, individuals mainly use their sense of sight, which allows individuals to understand visually elements, although observing often involves other senses such as hearing. This is necessary in the cases we need to remember information, perform precise actions, among others.

According to this, it is necessary to be an observer when crossing a street because this task or process requires concentration and precise actions and by observe you make sure that there is no danger of being hit by a car before crossing. So, the correct answer is A. Crossing the street

Simultaneous equations can be solved if the number of unknown variables are equal to the number of equations. In the geometry question, the equations are given by the relationship between the lines and angles

Part A

m = 7°, p = 10°, t = 5°, a = 6, and s = 2°

Part B

Arranging the variables from least to greatest gives; stamp

A stamp sits at the corner of an envelope but travels around the world

Part A

From the diagram, we have;

H is a vertical angle to the 90° angle

(7·m + 3)° + 90° + (8·m - 18)° = 180° (linear angles)

∴ (7·m + 3)° + (8·m - 18)°  = 180° - 90° = 90°

(15·m - 15)° = 90°

15·m = 90°+ 15° = 105°

m = 105°/15 = 7°

m = 7°

(7·m + 3)° = (5·p + 2)° (vertically opposite angle theorem)

∴ (5·p + 2)° = (7 × 7 + 3)° = 52°

p = (52° - 2°)/5 = 10°

p = 10°

(8·m - 18)° = (11·t - 17)° (vertically opposite angle theorem)

∴ (8 × 7 - 18)° = (11·t - 17)°

38° = (11·t - 17)°

11·t = 38° + 17° = 55°

t = 55°/11 = 5°

t = 5°

CD = 5·a + 12 and DE = 9·a - 12 are congruent segments

5·a + 12 = 9·a - 12 (Definition of congruent segments)

9·a - 5·a = 12 + 12 = 24

4·a = 24

a = 24/4 = 6

a = 6

(21·s + 6° and 48° are congruent congruent angles

21·s + 6° = 48° (Definition of congruent angles)

∴ s = (48° - 6°)/21 = 2°

s = 2°

Part B

Arranging the values of the variables from least to most gives;

s = 2°

t = 5°

a = 6

m = 7°

p = 10°

Which gives;

The answer to the riddle = s, t, a, m, p = Stamp

I saw this in my brothers math book. Hope this helps 

Answer:

[tex]y = \frac{48}{x}[/tex]

Step-by-step explanation:

Inverse variation:

if [tex]y \propto \frac{1}{x}[/tex]

then the equation is in the form of:

[tex]y = \frac{k}{x}[/tex]                 ....[1]

where, k is the constant of variation.

As per the statement:

When x = 3, y = 16 and when x = 6, y = 8.

Substitute the value of x and y to find k.

Case 1.

When x = 3, y = 16

then;

[tex]16=\frac{k}{3}[/tex]

Multiply by 3 both sides we have;

48 = k

or

k = 48

Case 2.

When x = 6, y = 8

then;

[tex]8=\frac{k}{6}[/tex]

Multiply by 6 both sides we have;

48 = k

or

k = 48

In both cases, we get constant of variation(k) = 48

then the equation we get,

[tex]y = \frac{48}{x}[/tex]

Therefore, the inverse variation equation can be used to model this function is, [tex]y = \frac{48}{x}[/tex]

The gradient of the line y=4x+7 is 4 and the y-intercept is 7. This line rises by 4 units vertically for every 1 unit it moves horizontally, and it intersects the y-axis at the point (0,7).

In the given line equation y=4x+7, the coefficient of x is the gradient (or slope) of the line and the constant term is the y-intercept. So, in this case, the gradient of the line is 4 and the y-intercept is 7. This means the line rises by 4 units vertically for every 1 unit it moves horizontally, and it intersects the y-axis at the point (0,7).

By applying the Intermediate Value Theorem to the function f(x)=x^4+6x^3-x^2-30x+4, we find that the intervals containing at least one zero, or root, are [-4,-3], [-3,-2], [-1,0], and [0,1].

In mathematics, particularly in calculus, the Intermediate Value Theorem (IVT) is used to show that a given interval has at least one zero, or root, of a function. In this case, the function is f(x)=x^4+6x^3-x^2-30x+4.

To apply IVT, we calculate the function value at the endpoints of the intervals. If the function values at the endpoints of an interval have different signs, then by IVT, there is at least one zero in that interval.

A change in sign between the function values at the endpoints of an interval indicates there is at least one root in that interval. Thus, by checking the signs of the consecutive function values, we can conclude that the intervals which contain at least one root are [-4,-3], [-3,-2], [-1,0], and [0,1].

The slope intercept form of a line is

[tex]y=mx+b[/tex]              .... (1)

where, m is slope and b is y-intercept.

Slope formula:

[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

The line passes through (0,12) and (1,21). The slope of the line is

[tex]m=\frac{21-12}{1-0}=9[/tex]

The slope of the line is 9. From the given table it is clear that the y-intercept or initial value of the function is 12.

Substitute m=9 and b=12 in equation (1).

[tex]y=9x+12[/tex]

The required equation is y = 9x + 12. Therefore the correct option is 3.

The y-intercept tells us where a line intersects the y-axis and the rate of change (slope) shows how much 'y' changes for a unit change in 'x'. Given these, we can identify different line characteristics based on whether the lines have the same or different y-intercepts and slopes.

Let's start by understanding the concepts of y-intercepts and rate of change. The y-intercept describes where a line intersects the y-axis. For example, in Figure A1, the y-intercept is 9, which means the line crosses the y-axis at y=9. Similarly, the rate of change, also known as the slope, indicates how much 'y' changes for each change in 'x'. A straight line will have the same slope at all points along the line, as illustrated in the example of Figure A1 where the slope is 3.

Now, let's compare the items:
A. When the y-intercepts are the same but the rates of change are different, the lines start at the same point on the y-axis, but diverge as 'x' increases because the slope of each line is different.
B. Different y-intercepts and different rates of change means that the lines start at different points on the y-axis and vary in how steeply they climb or fall.
C. When items have the same y-intercept and the same rate of change, these lines are coincident; they will overlap perfectly because they have the same starting point on the y-axis and ascend or descend at the same rate.
D. When the rates of change are the same but the y-intercepts are different, the lines are parallel. They rise or fall at the same rate, but they do not start at the same point on the y-axis.

The y-intercepts are the same, but the rates of change are different. The option (C) is correct.

To compare the y-intercepts and the rates of change of the given linear equation and the data in the table, we need to first understand each component:

  - The slope (rate of change) is the coefficient of [tex]\( x \),[/tex] which is [tex]\( 2 \).[/tex]

  - The y-intercept is the constant term, which is [tex]\( -4 \).[/tex]

Let's find the rate of change (slope) and the y-intercept for the data in the table.

The slope [tex]\( m \)[/tex] between two points [tex]\((x_1, y_1)\) and \((x_2, y_2)\)[/tex] is calculated as:

[tex]\[m = \frac{y_2 - y_1}{x_2 - x_1}\][/tex]

We'll calculate the slope using the points [tex]\((x, y)\)[/tex] from the table:

Using the points [tex]\((-4, -6)\) and \((-2, -5)\):[/tex]

[tex]\[m = \frac{-5 - (-6)}{-2 - (-4)} = \frac{-5 + 6}{-2 + 4} = \frac{1}{2}\][/tex]

Using the points [tex]\((-2, -5)\) and \((0, -4)\):[/tex]

[tex]\[m = \frac{-4 - (-5)}{0 - (-2)} = \frac{-4 + 5}{0 + 2} = \frac{1}{2}\][/tex]

We can see the rate of change is consistently [tex]\( \frac{1}{2} \).[/tex]

We can use the slope-intercept form [tex]\( y = mx + b \)[/tex]. We know [tex]\( m = \frac{1}{2} \)[/tex] and we can use any point from the table to find [tex]\( b \).[/tex]

Using the point [tex]\((0, -4)\):[/tex]

[tex]\[y = \frac{1}{2}x + b \\-4 = \frac{1}{2}(0) + b \\-4 = b\][/tex]

So the y-intercept [tex]\( b \)[/tex] is [tex]\( -4 \).[/tex]

Rate of change (slope):

 - Equation [tex]\( y = 2x - 4 \)[/tex] has a slope of [tex]\( 2 \).[/tex]

 - Table data has a slope of [tex]\( \frac{1}{2} \).[/tex]

Y-intercept:

Both the equation and the table data have a y-intercept of [tex]\( -4 \).[/tex]

Therefore, the correct comparison is (C) The y-intercepts are the same, but the rates of change are different.

The complete question is:

Compare the y-intercepts and the rates of change of the following items.

(A) The items have different y-intercepts and different rates of change.

(B) The rates of change are the same, but the y-intercepts are different.

(C) The y-intercepts are the same, but the rates of change are different.

(D) The items have the same y-intercept and the same rate of change.

Determine the known quantities and designate the unknown quantity as a variable while trying to set up or construct a linear equation to fit a real-world application.

Let's say it will take an "x" number of months to have $560.00.

Total money = fixed deposit + 45(number of months)

Given that,

Fixed deposit = $200

560 = 200 + 45x

45x = 360
