Final answer:
S5 represents Wen's salary in the fifth year after receiving a 3% annual raise from a starting salary of $100,000. Fifth year salary is $112,550.
Explanation:
The student is asking about an arithmetic sequence or a geometric sequence involving a salary increase. In this case, S5 represents the salary Wen will earn in the fifth year of her employment, assuming a 3% annual salary increase from a starting salary of $100,000. To calculate S5, we use the formula for the sum of a geometric sequence because a constant percentage change implies exponential growth. The first term (a) is her starting salary, the common ratio (r) is 1.03 (reflecting the 3% increase), and the term we want to calculate is the fifth term (n=5).
The formula for the nth term of a geometric sequence is Tn = a × r^(n-1), where Tn is the nth term, a is the first term, and r is the common ratio. Applying the formula:
First Term (a): $100,000Common Ratio (r): 1.03Fifth Term (S5): $100,000 × (1.03)^(5-1)S5 = $100,000 * (1.03)^4 = $100,000 * 1.1255 = $112,550.Therefore, S5 calculates the salary Wen will earn in year five after receiving a 3% raise each year from the starting salary of $100,000 to $112,550.

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
A certain store is advertising this deal: “Rent a TV for only $10.50 a week.” How much is this a year? (There are 52 weeks in a year.)
Answer:
Rent of a TV for one year would be $546.
Step-by-step explanation:
A certain store is advertising this deal :
"Rent a TV for only $10.50 a week."
We have to calculate the rent for a year.
As we know there are 52 weeks in a year.
∵ Rent of a TV for one week = $10.50
∴ Rent of a TV for one year = 10.50 × 52
= $546.00
Rent of a TV for one year would be $546.

A clock gains 0.020 s/min. how many seconds will the clock gain in exactly six months, assuming 30 days are in each month
Final answer:
To calculate the total seconds a clock gains in six months, we multiply the number of minutes in six months by the gain per minute, resulting in a total of 5,184 seconds gained.
Explanation:
The question asks us to determine how many seconds a clock gains over a six-month period, assuming each month has 30 days. The clock gains 0.020 seconds per minute.
To find the total seconds gained, we need to calculate the number of minutes in six months and then multiply that by the gain per minute. There are 60 minutes in an hour, 24 hours in a day, and the problem assumes 30 days in a month. Over six months, this totals:
60 minutes/hour × 24 hours/day × 30 days/month × 6 months = 259,200 minutesNow, multiply the total minutes by the gain per minute:
259,200 minutes × 0.020 seconds/minute = 5,184 secondsTherefore, the clock will gain a total of 5,184 seconds over a six-month period assuming each month has 30 days.

Pablo's goal is to have 5000 after 4 years is this possible if he invest with a rate of return of 6%
To achieve a future value of $5000 after 4 years with a 6% rate of return, Pablo would need to invest an initial amount.
Explanation:To calculate the future value of an investment with a given rate of return, you can use the formula:
FV = PV * (1 + r)ⁿ
Where FV is the future value, PV is the present value, r is the rate of return expressed as a decimal, and n is the number of years.
In this case, Pablo wants to have $5000 after 4 years with a 6% rate of return. Assuming he doesn't invest any initial amount, we can substitute these values into the formula:
FV = $0 * (1 + 0.06)⁴
FV = $0 * 1.262476
FV = $0

When x = 3, y = 16 and when x = 6, y = 8. Which inverse variation equation can be used to model this function? y = y = 48x y = y =
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]

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)

At Danielle’s clothing boutique, if an item does not sell for eight weeks, she marks it down by 15%. If it remains unsold after that, she marks it down an additional 5% each week until she can no longer make a profit. Then she donates it to charity. Rafael wants to buy a coat originally priced $150, but he can’t afford more than $110. If Danielle paid $100 for the coat, during which week(s) could Rafael buy the coat within his budget? Justify your answer.
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

Compare the y-intercepts and the rates of change of the following items. A. The y-intercepts are the same, but the rates of change are different. B. The items have different y-intercepts and different rates of change. C. The items have the same y-intercept and the same rate of change. D. The rates of change are the same, but the y-intercepts are different.
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.
Explanation: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.
https://brainly.com/question/19824331
#SPJ2
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.
