Mark just landed a great job as an engineer where he will make $65,000 a year. The company he will work for guarantees a 2% pay increase each year so it's employees' salaries keep up with inflation. At the end of the first year Mark will have made $65,000.
What is the explicit function that represents Mark's salary?
Answer:
The explicit function that represents Mark's salary is;
[tex]y = \$ 65,000 \times (1.02)^x[/tex]
Step-by-step explanation:
The given parameters are;
The amount Mark will make at annually as an engineer = $65,000
The percentage annual pay increase guaranteed by the company = 2%
The explicit function that represents Mark's salary can be presented as follows;
Let Mark's present salary = y
Therefore we have;
y = $65,000× (1 + 0.02)ˣ = $65,000× (1.02)ˣ
Mark salary, y at a particular year, x is y = $65,000× (1.02)ˣ.
#6) Beth saved a total of $30 per month for her first car. Beth saved

domain and range of the situation representing the amount of money
Beth saved in respect to time she saved? Write your answer in
interval notation.
D:
R:
Answer:
1) The domain In interval notation is [0, 20]
2) The range in interval notation is [100, 700]
Step-by-step explanation:
The given parameters are;
The amount Beth saved per month = $30
The number of months Beth saved = 20 months
The amount with which Beth opened her account = $100
Therefore, the amount of money Beth saved with respect to time is given as follows;
Y = $100 + $30 × X
Where;
Y = The amount of money Beth saved
X = The time (number of months) Beth saved
The domain is given as follows;
[tex]\{X | \ 0 \leq X \leq 20 \}[/tex]
The domain in interval notation is [0, 20]
For the range, when X = 0, Y = $100
When X = 20, Y = $100 + $30 × 20 = $700
Therefore, the range is given as follows;
[tex]\{Y | \ 100 \leq Y \leq 700 \}[/tex]
Which the range in interval notation is [100, 700].
If you have designed a test that measures principal leadership, and want to explore whether there are other constructs that are responsible for principal leadership, you would probably want to use which of the following techniques?
a. Factor analysis
b. Multi-trait
c. Pearson Product Moment Correlation
Answer:
Factor analysis
Step-by-step explanation:
Factor Analysis is a method for modeling observed variables, and their covariance structure, in terms of a smaller number of underlying unobservable “factors.” These factors are typically viewed as broad concepts or ideas that may describe a noted occurrence.
Take for example:
A basic impulse of acquiring a certain social level might explain most consumption behavior. These unobserved factors are more interesting to the social scientist than the noted numerical measurements.

A thread is wound 200 times round a reel of diameter 5cm. Use the value 3 for pie to find the approximate length of the thread in metres.
Answer:
L = 30 m
Step-by-step explanation:
lets make it simple and accurate
given
reel dia = 5 cm = 0.05 m
200 times round the reel
π = 3
reel O circumference = π d
Length of thread = Number of times round the reel x circumference
therefore,
L = 200 x (3 * 0.05)
L = 30 m
The approximate length of the thread wound around the reel is 30 meters.
Here, we have,
To find the approximate length of the thread wound around the reel, we can use the formula for the circumference of a circle.
Circumference = π * diameter
Given that
the diameter of the reel is 5 cm and we are using the value 3 for π, we can calculate the circumference:
Circumference = 3 * 5 cm
Circumference = 15 cm
Now, since the thread is wound 200 times around the reel, we need to calculate the total length of the thread:
Total length of thread = Circumference * Number of times wound
Total length of thread = 15 cm * 200
Total length of thread = 3000 cm
To convert the length from centimeters to meters, we divide by 100:
Total length of thread in meters = 3000 cm / 100
Total length of thread in meters = 30 meters
Therefore, the approximate length of the thread wound around the reel is 30 meters.

You estimate that the driving distance from Raleigh, NC to Charlotte, NC is around 180 miles. When you looked it up on the internet, you found that the actual distance is only 167.5 miles. What was the relative (percent) error of your estimate? In other words, how far off were you from the actual value?
Answer:
i. The relative error in the estimated distance is approximately 7.5%.
ii. The value of the estimated distance was about 12.5 miles far of from the actual value.
Step-by-step explanation:
Given that;
Estimated distance ≅ 180 miles
Actual distance = 167.5 miles
Then,
Estimated distance - Actual distance = 180 - 167.5
= 12.5 miles
So that,
Relative error = [tex](\frac{estimated distance - actual distance}{actual distance} )[/tex] × 100%
= [tex]\frac{12.5}{167.5}[/tex] × 100%
= 0.07463 × 100%
= 7.5%
i. The relative error in the estimated distance is approximately 7.5%.
ii. The value of the estimated distance was about 12.5 miles far of from the actual value.

(58-x)-(x)=12 in one variable
Answer:
x = 23
Step-by-step explanation:
Step 1: Write out equation
(58 - x) - (x) = 12
Step 2: Distribute negative
58 - x - x = 12
Step 3: Combine like terms
58 - 2x = 12
Step 4: Subtract 58 on both sides
-2x = -46
Step 5: Isolate x (divide both sides by -2)
x = 23
)A spinner is divided into sections of equal size, of which some are red, some are blue, and the remaining are green. The probability of the arrow landing on a section colored red is 50%. The probability of the arrow landing on a section colored blue is 10%. What is the probability of the arrow landing on a section colored green? I need help
Answer:
40%
Step-by-step explanation:
The probability of the arrow landing on the green section is a 40% chance
This is because there are only 3 sections where one is 50 and the other is 10
To find the green we can create an equation, where x = green section
50 + 10 + x = 100
The equation equals 100 because that's the highest the percentage will go in probability, unless we were told otherwise
60 + x = 100
x = 100 - 60
x = 40

Two airplanes leave the airport. Plane A departs at a 41° angle from the runway, and plane B departs at a 43° from the runway. Which plane was farther away from the airport when it was 5 miles from the ground? Round the solutions to the nearest hundredth.
Plane A / 7.62 mi away
Plane A / 6.63 mi away
Plane B / 6.84 mi away
Plane B / 7.33 mi away
Answer:
Plane A / 7.62 mi away
Step-by-step explanation:
We have to calculate the distance of each plane from the airport.
In other to do this, we would use the trigonometric function of Sine
sin θ = Opposite/Hypotenuse
For Plane A
Plane A departs at a 41° angle from the runway
sin θ = Opposite/Hypotenuse
θ = 41°
Distance from the ground = Opposite = 5 miles
Hypotenuse = ???
sin 41° = 5 miles/Hypotenuse
sin 41° × Hypotenuse = 5 miles
Hypotenuse = 5 miles/sin 41°
Hypotenuse = 7.6212654335 miles
Approximately to the nearest hundredth ≈ 7.62 miles
For Plane B
Plane B departs at a 43° from the runway
sin θ = Opposite/Hypotenuse
θ = 43°
Distance from the ground = Opposite = 5 miles
Hypotenuse = ???
sin 43° = 5 miles/Hypotenuse
sin 43° × Hypotenuse = 5 miles
Hypotenuse = 5 miles/sin 43°
Hypotenuse = 7.3313959282 miles
Approximately to the nearest hundredth ≈ 7.33 miles
From the above calculation, we can see that Plane A what 7.62 miles away from the airport while Plane b was 7.33 miles away from the airport.
Therefore Plane A was farther away from the airport (7.62 miles away) when it was 5 miles from the ground.

B is the midpoint of AC.
1. AB = 3x + 6 BC = 2x + 14 Find AC.
2. AB = 5x – 8 BC = 16 - 3x Find AC.
3. AC = 3x - 1 BC = 12-X Find AB.
4. AB = 2x + 11 BC = 4x - 5 Find AC.
5. AC = 6x-4 BC = 4x - 3 Find AB.
The value of,
1. AB = 3x + 6 BC = 2x + 14 then, AC = 5x + 20
2. AB = 5x – 8 BC = 16 - 3x then, AC = 2x + 8
3. AC = 3x - 1 BC = 12-X then, AB = 4x - 13
4. AB = 2x + 11 BC = 4x - 5 then AC = 6x + 6
5. AC = 6x-4 BC = 4x - 3 then AB = 2x - 1
What is Midpoint?
Midpoint is the point in the middle of the two endpoints of a line segment.
Now, B is midpoint of AC.
Then, AC = AB + BC
1. AB = 3x + 6, BC = 2x + 14
Then, AC = 3x + 6 + 2x + 14
AC = 6x + 20
2. AB = 5x – 8, BC = 16 - 3x
Then, AC = 5x - 8 + 16 - 3x
AC = 2x + 8
3. AC = 3x - 1, BC = 12-x
Then, AB =( 3x -1 ) - ( 12 - x )
AB = 2x - 13
4. AB = 2x + 11, BC = 4x - 5
Then, AC = 2x + 11 + 4x - 5
AC = 6x + 6
5. AC = 6x-4, BC = 4x - 3
Then, AB = (6x - 4) - ( 4x - 3 )
AB = 2x - 1
