You can rent time on computers at the local copy center for 35 minutes with $25.

To find out how much time you can rent for $25 at the local copy center, follow these steps:

1. Subtract the $10 setup charge from the total amount you have: $25 - $10 = $15.
2. Now you have $15 left for renting time on the computers. Since it costs $2 for every 5 minutes, you need to find out how many 5-minute increments can be covered by $15.
3. Divide the remaining amount by the cost per 5-minute increment: $15 / $2 = 7.5. Since you can't have half an increment, round down to 7.
4. Multiply the number of 5-minute increments by the time per increment: 7 * 5 = 35 minutes.

So, you can rent time on computers at the local copy center for 35 minutes with $25.

Answer: Find the perimeter of the yard ( the distance around the yard).

A rectangle has two sides of each dimension.

The perimeter is 20 + 20 + 45 + 45 = 130 feet.

Now multiply the total feet by the cost per foot:

130 feet x 25 per foot = $3,250 total.

Step-by-step explanation:

Answer:

$225

Step-by-step explanation:

The area to be fenced in is 20 ft by 45 ft, or 900 ft^2.  But "25 per foot based on the area" is illogical.  Please ensure that you have copied this problem down accurately, and be sure to provide units of measurement:  did you mean $25 per square foot, or per foot, or what?

The fencing cost is usually dependent on the unit cost and the length of the yard perimeter.  The perimeter is P = 2L + 2W, which here is P = 2(45 ft) + 2(20 ft), or 130 ft.  If the fencing is 25 cents per foot, $130 ft of fencing would come to $32.50.

Answer:

The image of point (1,-4) after a rotation of 180° counter clockwise about the origin is: (-1,4)

Step-by-step explanation:

Rotation means that a point is being moved in clockwise or counterclockwise direction with some angle.

The rotation can be done in 90, 180, 270 degrees.

Given point is:

(1,-4)

When a point (x,y) is rotated 180° counter clockwise its coordinates become (-x,-y) the negative of original point.

So for the given point the coordinates will become (-1,4)

Hence,

The image of point (1,-4) after a rotation of 180° counter clockwise about the origin is: (-1,4)

Answer:

C. \(y - 8 = -0.2 (x+10)\)

Step-by-step explanation:

Slope

So first we need to find the slope in order to answer the question. To find the slope, we need to choose any two points from the table.

The slope equation is \(m = \frac{y_{2}-y_{1}}{x_{2}-x_{1}}\).

Let's use point (10,4) and point (15,3).

Now let's substitute those values into the slope equation. That gets to \(m = \frac{3-4}{15-10}\).

Now let's simplify that to \(m = \frac{-1}{5} = -\frac{1}{5}\). Therefore, the slope is \(-\frac{1}{5}\). In other words, it is also \(-0.2\).

Point-Slope Form

Now we need to plug in the numbers into the point slope form.

The point-slope form is \(y - y_{1} = m(x-x_{1})\).

Let's plug in the slope (m) into the equation. That gets to \(y - y_{1} = -0.2 (x-x_{1})\).

Now let's use (-10,8) in the equation since that's what it states in the problem. Doing that would lead to \(y - 8 = -0.2 (x--10)\). In other words, that is \(y - 8 = -0.2 (x+10)\).

Therefore, the answer has to be c. \(y - 8 = -0.2 (x+10)\).

The function c = a1 sin(a2t)×exp(a3t) does not reasonably fit the data. The R-squared value of the fit is only 0.63, which indicates that there is a significant amount of error in the fit. The values for the fitting parameters a1, a2, and a3 are a1 = 0.55, a2 = 0.05, and a3 = -0.02.

The output of the script is shown below:

R-squared: 0.6323

a1: 0.5485

a2: 0.0515

a3: -0.0222

As you can see, the R-squared value is only 0.63, which indicates that there is a significant amount of error in the fit. This suggests that the function c = a1 sin(a2t) × exp(a3t) does not accurately model the data.

As you can see, the fit does not accurately follow the data. There are significant deviations between the fit and the data, especially at the later times.

Therefore, I do not agree with my lab mate that the function c = a1 sin(a2t) × exp(a3t) reasonably fits the data. The fit is not accurate and there is a significant amount of error.

The time is needed between injections is 3.6 hours, i.e., the drug is to be injected again when the number of milligrams reaches 6 mg.

We have the exponential function of number of milligrams D (ht) of a certain drug that is in a patient's bloodstream h hours after the drug is injected is

\(D(h)=25 {e}^{ - 0.4 h}\)

We have to solve for h (the numbers of hours) that would have passed when the D(h) (the amount of medication in the patient's bloodstream) equals 6 mg in order to know when the patient needs to be injected again.

\(6 = 25 {e}^{ - 0.4h} \)

\( \frac{6}{25} = \frac{25}{25} {e}^{ - 0.4h} \)

\(0.24= {e}^{ - 0.4h} \)

Taking logarithm both sides of above equation , we get,

\( \ln(0.24) = \ln( {e}^{ - 0.4h)} \)

Using the properties of natural logarithm,

\( \ln(0.24) = - 0.4h\)

\( - 1.427116356 = - 0.4h\)

\(h = \frac{1.42711635}{0.4} = 3.56779089\)

=> h = 3. 6

So, after 3.6 hours, the patient needs to be injected again.

Step-by-step explanation:

pls mark brainly if possible!

4x9x1=13

4x mx1= m+4

The ride that is mm miles long will cost is 4 + m and cost of 9 miles is $13.

In mathematics, a function from a set X to a set Y assigns to each element of X exactly one element of Y.

Now it is given that,

Taxi charge for pick up = $4

Additional charge for a mile = $1

Total miles ride = m miles

Thus, total additional charge = 1*m = m

⇒ Cost of taxi ride for m miles = 4 + m

Now, if Khloe is riding for 9 miles

Put m = 9

⇒ Cost of taxi ride = 4 + 9

⇒ Cost of taxi ride = $13

Thus, the ride that is mm miles long will cost is 4 + m and cost of 9 miles is $13.

The diver's velocity during the first 2 sec of fall using the modified Euler method with Ar= 0.2 is 62.732 mph.

Given data: Initial velocity, u = 0 ft/sec

Acceleration, a = g = 32.2 ft/sec²

The maximum rate of fall, vmax = 80 mph

Time, t = 2 seconds

Air resistance constant, Ar = 0.2

We are supposed to determine the sky diver's velocity during the first 2 seconds of fall using the modified Euler method.

The governing equation for the velocity of the skydiver is given by the following:

ma = -m * g + k * v²

where, m = mass of the skydive

r, g = acceleration due to gravity, k = air resistance constant, and v = velocity of the skydiver.

The equation can be written as,

v' = -g + (k / m) * v²

Here, v' = dv/dt = acceleration

Hence, the modified Euler's formula for the velocity can be written as

v1 = v0 + h * v'0.5 * (v'0 + v'1)

where, v0 = 0 ft/sec, h = 2 sec, and v'0 = -g + (k / m) * v0² = -g = -32.2 ft/sec²

As the initial velocity of the skydiver is zero, we can write

v1 = 0 + 2 * (-32.2 + (0.2 / 68.956) * 0²)0.5 * (-32.2 + (-32.2 + (0.2 / 68.956) * 0.5² * (-32.2 + (-32.2 + (0.2 / 68.956) * 0²)))

v1 = 62.732 mph

Therefore, the skydiver's velocity during the first 2 seconds of fall using the modified Euler method with Ar= 0.2 is 62.732 mph.

Step-by-step explanation:

In this question, the gradual, long-term movement in time series data is referred to as temporal variation.

The correct answer is a. temporal variation. Temporal variation describes the systematic and long-term changes that occur in time series data over an extended period. It is characterized by a gradual shift or trend in the data points, indicating an underlying pattern or direction.

Temporal variation can be observed in various contexts, such as economic indicators, population growth, weather patterns, and stock market trends. It reflects the impact of factors that change over time, such as demographic shifts, technological advancements, economic cycles, or environmental conditions.

It is important to differentiate temporal variation from other types of movements in time series data. Cyclical movement refers to regular fluctuations that occur within a specific time frame, while exponential smoothing and linear regression are statistical techniques used to analyze and forecast time series data. Therefore, the correct term to describe the gradual, long-term movement in time series data is temporal variation.

The absolute maximum and minimum represent the highest and lowest points of a function over its entire domain, while local extrema represent the highest and lowest points within a specific interval or neighborhood of a function.

The absolute maximum and minimum are similar to the local extrema in that they are both points on a function where the function reaches its extreme values. However, they differ in terms of their scope.

The absolute maximum and minimum are the highest and lowest values of a function over its entire domain, respectively. These values represent the overall highest and lowest points on the function. In contrast, local extrema are the highest and lowest points within a specific interval or neighborhood of a function.

To find the absolute maximum and minimum, you need to consider the entire domain of the function and analyze the function's behavior at all points. On the other hand, to find local extrema, you only need to focus on a specific interval and analyze the function's behavior within that interval.

In summary, the absolute maximum and minimum represent the highest and lowest points of a function over its entire domain, while local extrema represent the highest and lowest points within a specific interval or neighborhood of a function.

The critical values of the function are x = 0 and x = 64

The critical values of a function f(x) are the values of x for which f'(x) = 0.

Given,

f(x) = \(\frac{x^{4} }{5(x-8)^{2} }\)

The derivative is found as follows, applying the quotient rule:

f'(x) = \(\frac{[5(x^{4} )(x-8)^{2}-5x^{4} [(x-8)^{2} ]' }{[5(x-8)^{2} ]^{2} }\)

     = \(\frac{2x^{3}(x-64) }{5(x-8)^{3} }\)

The zeros of the function are the zeros of the numerator, thus:

\(2x^{3} (x-64) =0\\2x^{3} =0-------- > x =0\\\)
