Answer:

  17 bars

Step-by-step explanation:

Peter wants to compute the maximum number of bars he can load safely if the load limit of 1200 kg and the bar weight of 60 kg are each rounded to the number of significant digits those numbers have.

The error in a rounded number is assumed to be as much as half of the least significant digit of the number.

Peter's load limit may actually be as low as ...

  1200 kg - (1/2)(100 kg) = 1150 kg . . . . . . . 1200 is rounded to nearest 100

Peter's bar weight might be as high as ...

  60 kg + (1/2)(10 kg) = 65 kg . . . . . . . . . . . 60 is rounded to nearest 10

If Peter has maximum-weight bars and does not want to exceed the minimum his load limit might be, the number of bars he can load is ...

  (1150 kg) / (65 kg/bar) ≈ 17.7 bars

The greatest number of bars Peter can load safely is 17.

a) Comparing the two functions, Scooter's business has a lower slope of 15 compared to Karissa's business with a slope of 35. b) Both Scooter and Karissa earned a total of $500 in that month. Therefore, they had an equal month in terms of total money earned.

a) In the context of Scooter's business, the slope of the function f(x) = 200 + 15x represents the rate at which the total money earned increases with each additional sale. Each unit increase in x (number of sales) results in an increase of $15 in total money earned. The y-intercept of 200 represents the initial amount of money Scooter already had before making any sales.

In the context of Karissa's business, the slope of the function f(x) = 80 + 35x represents the rate at which the total money earned increases with each additional repair job. Each unit increase in x (number of repairs) results in an increase of $35 in total money earned. The y-intercept of 80 represents the initial amount of money Karissa already had before doing any repair jobs.

Comparing the two functions, Scooter's business has a lower slope of 15 compared to Karissa's business with a slope of 35. This means that Karissa's business earns more money per repair job compared to Scooter's business per t-shirt sale.

b) To determine who had the better month, we need to calculate the total money earned by each individual based on the given sales/repairs.

For Scooter, with x = 20 (number of shirts sold):

f(x) = 200 + 15x

f(20) = 200 + 15 * 20

f(20) = 200 + 300

f(20) = 500

For Karissa, with x = 12 (number of repairs):

f(x) = 80 + 35x

f(12) = 80 + 35 * 12

f(12) = 80 + 420

f(12) = 500

Both Scooter and Karissa earned a total of $500 in that month. Therefore, they had an equal month in terms of total money earned.

Answer:

Ima just steal the points

Step-by-step explanation:

Given:

Total principal = $5400

Interest rate of bank A = 10% = 0.10

Interest rate of bank B = 8% = 0.08

Total interest = $492

Let's find how much he deposited in each bank.

Equation for total principal:

A + B = 5400

Equation for total interest:

0.10A + 0.08B = 492

Hence, we have the system of equations:

A + B = 5400

0.10A + 0.08B = 492

Where A and B represents the amount deposited in each bank.

Let's solve the system simultaneously using substitution method:.

Rewrite the first equation for A:

A = 5400 - B

Substitute (5400 - B) for A in equation 2:

Divide both sides by -0.02:

Now, substitute 2400 for B in either of the equations:

Therefore, we have the following:

Amount deposited in the bank that pays 10% interest = $3000

Amount deposited in the bank that pays 8% interest = $2400

• ANSWER:

Amount deposited in the bank that pays 10% interest = $3000

Amount deposited in the bank that pays 8% interest = $2400

Answer:

x = -8, x = 5

Step-by-step explanation:

This can be solved using Factorization method:

\( 40 = 3x + {x}^{2} \\ \\ \implies \: {x}^{2} + 3x - 40 = 0 \\ \\ \implies \: {x}^{2} + 8x - 5x- 40 = 0 \\ \\ \implies \: x({x} + 8) - 5(x + 8) = 0 \\ \\ \implies \: ({x} + 8) (x - 5) = 0 \\ \\ \implies \: ({x} + 8) = 0 \: \: or \: \: (x - 5) = 0 \\ \\ \implies \: x = - 8 \: \: or \: \: x = 5 \\ \\ x = - 8, \: \: 5\)

Answer:

\(y - 4 = - 3(x - 2)\)

Part A: The function is nonlinear.

Part B: We determined the function to be nonlinear because the corresponding y-values do not change by a constant rate as the x-values increase, indicating a lack of a linear relationship.

Part A: The given function is nonlinear.

Part B: To determine whether the function is linear or nonlinear, we need to examine the relationship between the x-values and the corresponding y-values in the table.

In a linear function, there is a constant rate of change between the x and y values.

This means that for every increase in x by a fixed amount, the corresponding y value will change by a constant amount.

If we look at the x-values in the given table (2, 3, 4), we can see that they are increasing by a fixed amount of 1 each time.

However, when we examine the corresponding y-values (20, 10, 40), we don't see a constant rate of change.

The y-values are not changing by the same amount for each increase in x.

For instance, when x increases from 2 to 3, the y-value decreases from 20 to 10.

This indicates a non-linear relationship as the change in y is not constant for each unit increase in x.

Additionally, when x increases from 3 to 4, the y-value jumps significantly from 10 to 40, which further confirms the nonlinear nature of the function.

Based on these observations, we can conclude that the given function is nonlinear.

Answer:

Step-by-step explanation:

i really need the points

let us build equation for unknown legs

If we keep the length pf one leg as x

the other leg would be x +3

so we can build a relationship using pythagoras theorem

x^2 + (x+3)^2 = 15^2

x^2 + x^2 + 6x + 9 = 225

2x^2 + 6x + 9 = 225

2x^2 + 6x+ 9-225 = 0

2x^2 + 6x - 216 = 0

x^2 + 3x - 108 = 0 dividing whole equation by 2

x^2 + 12x - 9x - 108 = 0

x ( x + 12 ) - 9 (x + 12) = 0

(x -9) ( x +12) = 0

solutions for x are

x = 9 or x = -12

as lengths cannot be negative

one side length is 9cm

and other which is( x + 3)

9 + 3

12cm

The lengths of the legs of the right angled triangle is 9 feet and 12 feet.

Pythagoras theorem is used to show the relationship between the sides of a right angled triangle. It is given by:

Hypotenuse² = First Leg² + Second leg²

Let x represent the length of one leg. The other leg is three more = x + 3, hypotenuse = 15 ft. Hence:

15² = x² + (x + 3)²

x² + 6x + 9 + x² = 225

2x² + 6x - 216 = 0

x² + 3x - 108 = 0

x = - 12 or x = 9

Since the length cant the negative hence x= 9, x + 3 = 12

The lengths of the legs of the right angled triangle is 9 feet and 12 feet.

Based on these calculations, Option 3 yields the highest future value at age 35.

To compare the investment options at different ages, we can use the future value formula:

FV = PV * (1 + r)^t

where:

FV = future value of the investment

PV = present value or initial investment

r = annual growth rate (as a decimal)

t = number of years the investment grows

Here are the general equations for each option:

To compare the options at ages 20, 25, 30, and 35, calculate the future value for each option at those ages by plugging in the corresponding value of t.

Age 20:

FV1 = N/A (Option 1 hasn't started yet)

FV2 = 50 * (1 + 0.08)^0 = $50

FV3 = N/A (Option 3 hasn't started yet)

Age 25:

FV1 = N/A (Option 1 hasn't started yet)

FV2 = 50 * (1 + 0.08)^5 ≈ $73.86

FV3 = 100 * (1 + 0.07)^0 = $100

Age 30:

FV1 = 50 * (1 + 0.09)^0 = $50

FV2 = 50 * (1 + 0.08)^10 ≈ $107.95

FV3 = 100 * (1 + 0.07)^5 ≈ $140.26

Answer:

Area of ΔQRS = 2.3 square inches

Step-by-step explanation:

From the given information,

<S + <Q + <R = \(180^{o}\)

51 + 44 + <R = \(180^{o}\)

95 + <R = \(180^{o}\)

<R = \(180^{o}\) - 95

    = \(85^{o}\)

<R = \(85^{o}\)

Applying the Sine rule, we have;

\(\frac{q}{SinQ}\) = \(\frac{r}{SinR}\) = \(\frac{s}{SinS}\)

Using \(\frac{r}{SinR}\) = \(\frac{s}{SinS}\)

\(\frac{r}{Sin 85}\) = \(\frac{2.3}{Sin51}\)

r = \(\frac{2.3*Sin85}{sin51}\)

  = 2.9483

r = 2.9 inches

Also, \(\frac{q}{SinQ}\) = \(\frac{s}{SinS}\)

\(\frac{q}{Sin44}\) = \(\frac{2.3}{Sin51}\)

q = \(\frac{2.3*Sin44}{Sin51}\)

  = 2.0559

q = 2.0 inches

From Herons formula,

Area of a triangle = \(\sqrt{s(s-q)(s-r)(s-s)}\)

s = \(\frac{2.3 + 2.0 + 2.9}{2}\)

  = 3.6

Area of ΔQRS = \(\sqrt{3.6(3.6-2.0(3.6-2.9)(3.6-2.3)}\)

Report on the Analysis of American Airlines (Domestic) PerformanceThe quantitative analysis focused on three variables- load factors, revenue passenger miles, and available seat miles for American Airlines.

The Bureau of Transportation Statistics data for domestic flights from January 2006 to December 2012 was retrieved for the analysis. The quantitative analysis also focused on finding critical statistical values like mean, median, mode, standard deviation, variance, and minimum/maximum variables. The results of the data are summarized in Table 2. Revenue Passenger Miles (RPM) mean is 6,624,897, the median is 6,522,230, and mode is NONE. The minimum is 5,208,159 and the maximum is 8,277,155. The standard deviation is 720,158.571, and the variance is 518,628,367,282.42.

Load Factors (LF) mean is 82.934, the median is 83.355, and mode is 84.56. The minimum is 74.91, and the maximum is 89.94. The standard deviation is 3.972, and the variance is 15.762. The Available Seat Miles (ASM) mean is 7,984,735, the median is 7,753,372, and mode is NONE. The minimum is 6,734,620, and the maximum is 9,424,489. The standard deviation is 744,469.8849, and the variance is 554,235,409,510.06.Figure 1 above displays the performance of American Airlines (Domestic).

The mean RPM is 7,984,735, and the linear regression line is y = 50584x - 2.53E+8. The linear regression line indicates a positive relationship between RPM and year, with a coefficient of determination, R² = 0.6806. A coefficient of determination indicates the proportion of the variance in the dependent variable that is predictable from the independent variable. Therefore, 68.06% of the variance in RPM is predictable from the year. A one-way ANOVA analysis of variance test was conducted to determine the equality of means of three groups of variables; RPM, ASM, and LF. The null hypothesis is that the means of RPM, ASM, and LF are equal.

The alternative hypothesis is that the means of RPM, ASM, and LF are not equal. The level of significance is 0.05. The ANOVA results indicate that there is a significant difference in means of RPM, ASM, and LF (F = 17335.276, p < 0.05). Furthermore, a post-hoc Tukey's test was conducted to determine which variable means differ significantly. The test indicates that RPM, ASM, and LF means differ significantly.

The skewness test was conducted to determine the symmetry of the distribution of RPM, ASM, and LF. The test indicates that the distribution of RPM, ASM, and LF is not symmetrical (Skewness > 0).

Additionally, the z-statistic test was conducted to determine the deviation of RPM, ASM, and LF from the mean. The test indicates that RPM, ASM, and LF significantly deviate from the mean.

After answering the presented question, we can conclude that We only coordinates need the positive solution, so t = 1.259

A coordinate in mathematics is a number or combination of integers that indicates the position of a point or object in space. Coordinates are often used to define the position of a point or object in a certain coordinate system, such as the Cartesian or polar coordinate systems. A point, for example, is located in the Cartesian coordinate system by its distance from the origin along the x-axis and its distance from the origin along the y-axis. These distances are denoted by two numbers, the x-coordinate and the y-coordinate, respectively. The two coordinates specify the point's position in the plane.

To find the point that is 2/5 of the way from V to W, w

\(d = \sqrt((x2 - x1)^2 + (y2 - y1)^2)\\\)

where (x1, y1) = (-4, -4) and (x2, y2) = (11, 2).\\

\(d = \sqrt((11 - (-4))^2 + (2 - (-4))^2)\\= \sqrt(15^2 + 6^2)\\= \sqrt(225 + 36)\\= \sqrt(261)\\\)

\(d1 = (2/5) * \sqrt(261)\\x = -4 + t * (11 - (-4))\\d1 = s\qrt((x - (-4))^2 + (y - (-4))^2)\\= \sqrt((x + 4)^2 + y^2 - 8x - 8y + 32)\\\)

\(d1^2 = (x + 4)^2 + y^2 - 8x - 8y + 32\\d1^2 = (x + 4)^2 + y^2 - 8x - 8y + 32\\= (x + 4)^2 + y^2 - 8(x + 4) - 8y + 64 \\d1^2 = (x + 4)^2 + y^2 - 8(x + 4) - 8y + 64\\= (x + 4)^2 + (y - 4)^2 + 4 )\\(2/5)^2 * 261 = (x + 4)^2 + (y - 4)^2 + 4\\\)

\(52.2 = (x + 4)^2 + (y - 4)^2 + 4\\(x + 4)^2 + (y - 4)^2 = 48.2\\(x + 4)^2 + y^2 - 8x - 8y + 32 = 48.2 \\(x + 4)^2 + (-4 + 6t)^2 - 8x + 48t - 32 = 48.2\\(x + 4)^2 + 36t^2 - 48t + 32 = 48.2\\(x + 4)^2 + 36t^2 - 48t - 16.2 = 0\\\)

Using the quadratic formula:

\(t = (48 + sqrt(48^2 - 4 * 36 * (-16.2))) / (2 * 36)\\= (48 + sqrt(2596.8)) / 72\\= (48 + 50.956) / 72\\t = 1.259 or t = -0.705\\\)
