\(1486.25\)EXPLANATION
The total (after-tax) cost is $1567
Tax rate is 5.5%
Let the retail ( pre-tax ) price be x
Hence;
\(\begin{gathered} x+5.5\%x=1567.99 \\ x+\frac{5.5x}{100}=1567.99 \\ \frac{100x+5.5}{100}=1567.99 \\ \end{gathered}\)Cross multiply and solve;
\(\begin{gathered} \frac{100x+5.5}{100}=1,567.99 \\ 100x+5.5x=156799 \\ 105.5x=156799 \\ x=\frac{156799}{105.5} \\ =1486.245 \end{gathered}\)Therefore, the retail price of the laptop is $1486.25

(A) To use the exponential formula, we need to determine the values of P, r, and n.
P = $8,500, the initial deposit
r = 2.6% = 0.026, the annual interest rate
n = 4, the number of times interest is compounded per year (quarterly)
How much money will Deshawn will have in the account in 9 years?(B) The formula for the future value of the account is:
A = \(P(1 + r/n)^{nt}\)
where t is the time in years. Plugging in the values from part (A) and t = 9, we get:
A = \($8,500(1 + 0.026/4)^{(4×9)}\) = $11,169.62
Therefore, Deshawn will have $11,169.62 in the account after 9 years.
(C) The annual percentage yield (APY) takes into account the effect of compounding on the interest rate. The formula for APY is:
APY = \((1 + r/n)^{n}\) - 1
Plugging in the values from part (A), we get:
APY = \((1 + 0.026/4)^{4}\) - 1 = 0.02639
Therefore, the APY for the savings account is 2.639%.

What is the equation of the line that is parallel to the line defined by the equation y = 3x−7 and goes through the point (4, 2)?
Answer:
\(y-2=3(x-4)\)
Step-by-step explanation:
Pre-SolvingWe are given a line contains the point (4, 2).
We also know that the line is parallel to y= 3x - 7.
We want to write the equation of this line.
Parallel lines have the same slopes.
First, let's find the slope of y = 3x - 7.
3 is in the place of where m (the slope) is, so that means it is the slope of that line.
It is also the slope of the line whose equation we want to write.
The equation of the line can be written in three ways:
Slope-intercept form, which is y=mx+b, where m is the slope and b is the y-intercept. Standard form, which is ax+by=c, where a, b, and c are free integer coefficients. a and b cannot be 0, and a is usually non-negative as well. Point-slope form, which is \(y-y_1=m(x-x_1)\), where m is the slope and \((x_1, y_1)\) is a point.All of these ways are valid, but for this problem, let's write the equation in point-slope form, as it is the easiest.
SolvingSubstitute 3 as m in \(y-y_1=m(x-x_1)\).
\(y-y_1=3(x-x_1)\)
Now, substitute 4 as \(x_1\) and 2 as \(y_1\).
\(y-2=3(x-4)\)

c) Mode: 15 (appears 6 times)
Mean: 15.25
Median: 15
d) Probability of being 13 years old: 2/20 = 0.1 or 10%
e) Probability of being 14 or 16 years old: 6/20 = 0.3 or 30%
f) Probability of not having 15 years old: 1 - (6/20) = 14/20 = 0.7 or 70%
a) To create a table and calculate the absolute frequency, relative frequency, and percentual frequency, we organize the given ages in ascending order:
13 13 14 14 15 15 15 15 15 16 16 17 17 17 18 18
Age Absolute Frequency Relative Frequency Percentual Frequency

17 3 3/16 18.75%
18 2 2/16 12.5%
b) To represent the data graphically with a histogram, we plot the ages on the x-axis and the absolute frequency on the y-axis:
c) To calculate the mode, mean, and median:
Mode: The mode is the most frequently occurring age in the dataset. In this case, the mode is 15, as it appears 5 times.
Mean: The mean is the average of all the ages. To calculate it, we sum up all the ages and divide by the total number of ages:
(13 + 13 + 14 + 14 + 15 + 15 + 15 + 15 + 15 + 16 + 16 + 17 + 17 + 17 + 18 + 18) / 20 = 306 / 20 = 15.3
Median: The median is the middle value in the dataset when arranged in ascending order. In this case, the median is 15 since it falls in the middle.
d) To calculate the probability of having 13 years old, we divide the absolute frequency of 13 (2) by the total number of ages (20):
Probability of 13 years old = 2/20 = 0.1 or 10%
e) To calculate the probability of having 14 or 16 years old, we add the absolute frequencies of 14 and 16 (2 + 2 = 4) and divide by the total number of ages (20):
Probability of 14 or 16 years old = 4/20 = 0.2 or 20%
f) To calculate the probability of not having 15 years old, we subtract the absolute frequency of 15 (5) from the total number of ages (20):
Probability of not having 15 years old = (20 - 5)/20 = 0.75 or 75%

Find the slope of the line passing through the given points. State whether the line is increasing, decreasing, horizontal, or vertical. (7,3) and (8,7)
Answer:
slope = 4
The line is increasing
Step-by-step explanation:
slope can be found through the equation \(\frac{y_{2} -y_{1}}{x_{2}-x_{1}}\). So, if we plug these points in, we get \(\frac{7-3}{8-7}\), which simplifies to 4. So, the slope is 4.
Since the slope is positive, the line is increasing.
5. If the dimensions of a figure are multiplied by 4,
how many times larger will the volume be?
Answer:
The volume will be 64 times larger.
Explanation:
When you multiply two single dimensions, such as length and width, the units will change from units to units squared (example: 2 ft * 2 ft = 4 ft^2). Similarly, When you multiply three single dimensions the units will change from units to units cubed (example: 2 ft * 2 ft * 2 ft = 8 ft^3). You can use the exponents as a trick to solve this type of question. For example, in this case, volume means that you are multiplying three single dimensions. Therefore, the end result will be units cubed. If each dimension is multiplied by four, you can cube the factor to find how many times larger the volume will be: 4^3 = 64.
TLDR: Since there are three dimensions, multiply 4 by itself three times to get the answer: 4 * 4 * 4 = 64.
In case I explained it badly, here is a more mathematical method to find the answer:
The formula for volume:
V = l * w * h
When you multiply each dimension by 4:
V = (4 * l) * (4 * w) * (4 * h)
Rearrange with the Commutative Property of Multiplication:
V = (4 * 4 * 4) * (l * w * h)
Simplify:
V = 64 * l * w * h
Therefore, the volume is 64 times greater.

What is the slope for this scenario?
In the given scenario slope is increasing and the value of increasing slope is 2.
Slope may be defined as the extent of steepness of a curve in a graph in the given question x is given by miles driven in the cab and y represents the cost. y is the dependent variable and x in independent because the cost depends on the amount of miles driven. Here, in the question as the miles driven by the car increases the cost also increases. This proves that if the data is plotted on graph, it will give an increasing slope.
The value of slope can be determined by
Slope = (10.0 - 7.50)/(2.50 - 1.25)
Slope = 2.5/1.25
Slope = 2
This also gives a positive value. Thus, the slope is increasing.

What is the gravitational force acting on a 70.0 kg object standing on the Earth’s surface?
Answer:
What is the gravitational force acting on a 70.0 kg object standing on the Earth’s surface?
Step-by-step explanation:
The gravitational force acting on a 70.0 kg object standing on the Earth’s surface can be calculated using the formula:
F = G * (m1 * m2) / r^2
Where:
F = gravitational force
G = gravitational constant (6.6743 x 10^-11 N*m^2/kg^2)
m1 = mass of the first object (in this case, the mass of the Earth)
m2 = mass of the second object (in this case, the mass of the object, 70.0 kg)
r = distance between the centers of the two objects (in this case, the radius of the Earth, which is approximately 6,371 km)
Using the values above, we can calculate the gravitational force as follows:
F = (6.6743 x 10^-11 N*m^2/kg^2) * (5.97 x 10^24 kg * 70.0 kg) / (6,371,000 m)^2
F = 686.6 N
Therefore, the gravitational force acting on a 70.0 kg object standing on the Earth’s surface is approximately 686.6 N.
One meter of shielded microphone cable weighs 75/1,000 kilogram. What is the length of cable in coil that weigh 5 1/2 kilogram
The length of cable in the coil that weighs 5 1/2 kilograms is 1/2 meter.
Let x be the length of cable in meters that weighs 5 1/2 kilograms.
Then, we can write:
1 meter / (75/1000) kilograms = x meters / 5.5 kilograms
Simplifying the left side, we get:
1 meter / (75/1000) kilograms = 1000 / 75 meters/kilogram
= 40/3 meters/kilogram
Substituting this into our proportion, we get:
40/3 meters/kilogram * x meters = 5.5 kilograms
Multiplying both sides by 3/40, we get:
x meters = (5.5 kilograms) * (3/40) * (40/3 meters/kilogram)
= 1/2 meter
The length is 1/2 meter
