Using compound interest formula, the final payment for a principal of $12000 compounded continuously at rate of 5% is $13,097.31
What is Compound InterestCompound interest is the interest calculated on the initial principal and also on the accumulated interest of previous periods of a deposit or loan. It is the addition of interest to the principal sum of a loan or deposit, or in other words, interest on interest. It is the result of reinvesting interest, rather than paying it out, so that interest in the next period is then earned on the principal sum plus previously accumulated interest.
The formula of compound interest is given as;
A = P(1 + r/n)^nt
A = compound interestP = principalr = rate n = number times t = timeSubstituting the values into the formula
A = Pe^rt
This formula is only for continuously compounded
A = 12000e^(0.05 * 1.75)
A = $13,097.31

Write an expression to show how much it will cost if Kenny buys x number of hotdogs and each hot dog costs $2.
The expression to show how much it will cost if Kenny buys x number of hotdogs is x * $2.
To find the total cost if Kenny buys x number of hotdogs, we can multiply the number of hotdogs (x) by the cost per hotdog ($2). The expression to calculate the cost would be:
Total Cost = x * $2
In this expression, x represents the number of hotdogs Kenny wants to buy, and $2 represents the cost per hotdog.
For example, if Kenny wants to buy 5 hotdogs, we can substitute x with 5 in the expression:
Total Cost = 5 * $2
Simplifying the expression:
Total Cost = $10
So, if Kenny buys 5 hotdogs, it will cost him $10 in total.
Similarly, if Kenny buys any other number of hotdogs, we can substitute that value for x in the expression to calculate the corresponding total cost.
In summary, the expression to show how much it will cost if Kenny buys x number of hotdogs is x * $2.

The estimated error in the calculated area is approximately 3.2ft²
How did we estimate the error?To estimate the error in the calculated area of a square, use linear approximation or differentials.
The area of a square is given by the formula A = s², where s represents the length of a side.
Calculate the area of the square using the given side length of 16 ft:
A = (16 ft)²
A = 256 ft²
Now, let's consider the possible error in the side length, which is ±0.1 ft. Treat this error as a change in the side length (Δs) and use linear approximation or differentials to estimate the corresponding change in the area (ΔA).
Using linear approximation, express the change in the area as:
ΔA ≈ 2s Δs
Substituting the values:
ΔA ≈ 2(16 ft)(0.1 ft)
ΔA ≈ 3.2 ft²
Therefore, the estimated error in the calculated area is approximately 3.2ft².

A car travels for 10minutes.
At the beginning of the trip, the car traveled at a speed
of 13 m/s. At the end of the trip the car was traveling at a speed of 6 m/s. What is
the acceleration of the car?
Answer:
0.01167 m/s^2
Step-by-step explanation:
Acceleration is chage in velocity with respect to time. Another way to think of acceleration is in the units: m/s^2, or as I like to say, (m/s) /s.
The strategy to solve this kind of problem is to find the change in velocity (which will be in units of m/s)... and then divide that by the time passed.
In this case:
Change in Velocity = (13 m/s) - (6 m/s) = 6 m/s
Time passed = 10 min
Converting units of time: 10 min * (60 s / 1 m) = 600 sec
Acceleration = Change in Velocity / Time Passed
Acceleration = (6 m/s) / (600 s)
Acceleration = 0.01167 m/s^2
The distribution for the life of refrigerators is approximately normal with a mean of 14 years and a standard deviation of 2.5 years. What percentage of refrigerators have lives between 11 years and 18 years?
The percentage of refrigerators that have lives between 11 years and 18 years is approximately 83.01%.
The values of 11 years and 18 years using the given mean and standard deviation, and then find the area under the standard normal curve between those two standardized values.
First, we standardize the value of 11 years:
z1 = (11 - 14) / 2.5 = -1.2
Next, we standardize the value of 18 years:
z2 = (18 - 14) / 2.5 = 1.6
Now we need to find the area under the standard normal curve between these two standardized values.
We can use a standard normal table or calculator to find this area.
Using a standard normal table, we can find the area between z = -1.2 and z = 1.6 by finding the area to the left of z = 1.6 and subtracting the area to the left of z = -1.2:
Area = P(-1.2 < z < 1.6) = P(z < 1.6) - P(z < -1.2)
Looking up these values in the standard normal table, we find:
P(z < 1.6) = 0.9452
P(z < -1.2) = 0.1151
Substituting these values, we get:
Area = 0.9452 - 0.1151 = 0.8301

HELP ME ASAP PLEASE
Answer:
451$
Step-by-step explanation:
$1,204 + $600 = 1804$
Since there are 4 members on the team, we divide the total sum of costs by 4.
$1804/4 = 451$.
Answer:
The athletic department spent $1,204 on airline tickets and $600 on hotel costs for the 4 members of the tennis team. To find out how much was spent for each member of the tennis team, you can add the cost of airline tickets and hotel costs and then divide by the number of members.
So, the total cost for airline tickets and hotel costs is $1,204 + $600 = $1,804. Since there are 4 members on the tennis team, the cost per member is $1,804 ÷ 4 = $451.
Therefore, $451 was spent for each member of the tennis team.

The next flight was with another airline that had the same weight limit. Nancy had to pay $4 per pound that her bag was over the weight limit, in addition to the checked bag fee of $25. By coincidence, the fees ended up being the same with both airlines. How far over the weight limit was the bag? Write a system of equations, graph them, and type the solution.
Nancy's bag was 0.2kg over the weight limit.
What weight in which Nancy's bag exceeded limit?Let's denote the weight limit as x.
The total cost for the first airline can be expressed as:
Cost1 = 20x + 5
The total cost for the second airline is given by:
Cost2 = 25x + 4
As fees were same with both airlines, we will set up equation to find the weight difference:

The solution set of given inequalities are represented by Part A.
The given inequalities are
⇒ y ≥ x + 1 and y + x > -1
Hence, The related equations of both inequalities are
y = x + 1
Put x=0, to find the y-intercept and put y=0, to find x intercept.
y = 0 + 1
y = 1
And, 0 = x + 1
x = - 1
Therefore, x-intercept of the equation is (-1,0) and y-intercept is (0,1).
Similarly, for the second related equation
y + x = - 1
y + 0 = - 1
y = - 1
0 + x = - 1
x = - 1
Therefore x-intercept of the equation is (-1,0) and y-intercept is (0,-1).
Now, join the x and y-intercepts of both lines to draw the line.
Now check the given inequalities by (0,0).
0 ≥ 0 + 1
