Answer:

14.35 ft

Step-by-step explanation:

We can use the pythagorean theorem to find the distance between the poles since both triangles are right triangles.

a^2 + b^2 = c^2

a^2 + 12^2 = 14^2

a^2 + 144 = 196

a^2 = 52

a = 7.21 ft

a^2 + b^2 = c^2

a^2 + 7^2 = 10^2

a^2 + 49 = 100

a^2 = 51

a = 7.14 ft

7.21 + 7.14 = 14.35 ft

Using it's concept, the rate of change between point C and point D is of 2.

The average rate of change of a function is given by the change in the output divided by the change in the input. Hence, over an interval [a,b], the rate is given as follows:

\(r = \frac{f(b) - f(a)}{b - a}\)

Considering the points of the given linear function, we have that:

Answer:

Step-by-step explanation:

Let the price for children and adults package be represented with x and y respectively.

For the first week the sum of the package will be as follows:

3x+8y = 126

For the two weeks after:

6x+4y= 108

So, we will be having two equations

3x+8y = 126..... (1)

6x+4y= 108.......(2)

These are simultaneous equations

From equation 1

3x+8y = 126

3x = 126-8y

X = 126-8y/3 ............. (3)

Put equation 3 into 2

6 ( 126-8y)/3 +4y = 108

756-48y/3 +4y = 108

756-48y+12y/3 = 108

Cross multiplying

756-48y+12y= 108×3

756-48y+ 12y = 324

Collecting like terms

756-324 = 48y-12y

432= 36y

Divide both sides by 36

432/36 = 36y/36

y= 12

Substituting y into equation 1

3x+8= 126

3x+96=126

3x= 126-96

3x= 30

Divide both sides by 3

3x/3 = 30/3

x = 10

Hence for each of the packages for children and adults. It will be 10 and 12 respectively.

The equation to represent the scenario is 3y - 38 = 10

Represent the given parameters as

x = Dominique

y = Roberto

From the question, we have

Dominique spent $38 less than 3 times what Roberto spent

This means that

x = 3y - 38

Also, Dominique spent $10

So, we have

3y - 38 = 10

Hence, the equation to represent the scenario is 3y - 38 = 10

Answer:

B.(4,20)

Step-by-step explanation:

Given: \(x^2 -24x = -80\)

To solve the quadratic equation by completing the square, we follow these steps.

Step 1: Divide the coefficient of x by 2

\(-\dfrac{24}{2}=-12\)

Step 2: Square your result fro Step 1

\((-12)^2\)

Step 3: Add the result form step 2 to both sides of the equation

\(x^2 -24x+(-12)^2 = -80+(-12)^2\)

Step 4: Rewrite the Left hand side in the form \((x+k)^2\)

\((x-12)^2=-80+144\\(x-12)^2=64\)

Step 5: Take square roots of both sides

\(x-12=\pm \sqrt{64}\)

Step 6: Solve for x

\(x=12\pm \sqrt{64}\\=12\pm8\\x=12+8$ or x=12-8\\x=20 or x=4.\)

Therefore, the solution set of the equation is (4,20).

The median number of emails sent per day in the given survey is 23.

To find the median, we first need to arrange the data in order from smallest to largest

20 20 20 21 22 22 22 23 23 24 24 25 26 26 27 27 27 27 27 27

The median is the middle value in the ordered list. Since there are 20 observations, we can find the median as follows

The 10th observation is 24, which is the first value greater than or equal to the median.

The 9th observation is 23, which is the last value less than or equal to the median.

Therefore, the median number of E-mails sent per day is 23.

The single sample t-test is primarily used to test a single group against a population norm.

It is a parametric test that compares the mean of a single group to a known population mean. This test is often used when the researcher wants to determine if the group differs significantly from the population norm. The single sample t-test is not a post-hoc test for an Analysis of Variance (ANOVA), as mentioned in option b. ANOVA is used to compare the means of multiple groups, while the single sample t-test focuses on comparing a single group to a population norm.

Option c suggests that the single sample t-test is used as the primary test of differences in place of an independent groups t-test when homogeneity of variance does not exist. However, the independent groups t-test is specifically designed to compare the means of two independent groups, and the single sample t-test serves a different purpose.

Option d correctly states that the single sample t-test is a primary parametric test of differences used for one independent variable with the subjects being the same group being tested. It assesses whether the mean of the sample significantly differs from a known population mean.

In summary, the single sample t-test is used to test a single group against a population norm, making it a primary parametric test for comparing the mean of one group to a known population mean.

With x = 9 and y = 9, the minimum value of q is 729.

We have,

The concept used to solve the problem is substitution.

By substituting the given values of x and y into the function

\(q = 6x^2 + 3y^2\), we can evaluate the expression and find the minimum value.

Substitution allows us to replace the variables with their specific values and simplify the equation to obtain the result.

To minimize the function q = \(6x^2 + 3y^2\) with the constraint x = 9 and y = 9, we substitute the given values into the function.

Substituting x = 9 and y = 9 into q, we have:

\(q = 6(9)^2 + 3(9)^2\)

= 6(81) + 3(81)

= 486 + 243

= 729

Therefore,

With x = 9 and y = 9, the minimum value of q is 729.

As per the given distance, the bus and the motorcycle will pass each other at 4:50 pm.

Now, let's find the distance the bus travels during that time. We know the speed of the bus is 60 mph, so we can use the formula distance = speed x time. Thus, the distance the bus travels is:

distance = speed x time

distance = 60 x t

Next, let's find the distance the motorcycle travels during the same time. The speed of the motorcycle is 72 mph, so we can use the same formula to find the distance the motorcycle travels:

distance = speed x time

distance = 72 x (t - 3/4)

Here, we subtract 3/4 from the time because the motorcycle leaves 45 minutes later than the bus. Remember, we need to convert 45 minutes to hours by dividing it by 60. Therefore, 45 minutes is equal to 3/4 of an hour.

Now that we have both distances, we can set them equal to each other since the bus and the motorcycle will meet at the same point in time:

60t = 72(t - 3/4)

Let's simplify and solve for "t":

60t = 72t - 54

12t = 54

t = 4.5

Therefore, it will take 4.5 hours for the bus and the motorcycle to meet each other. But, we need to find out what time that will be. We know the bus left at 12:20 pm, so we add 4.5 hours to that time:

12:20 pm + 4.5 hours = 4:50 pm

Answer:

(-∞,∞)

Step-by-step explanation:

The domain is all possible x values of the function

There are no constraints or holes for this and therefore the domain is all real numbers

A function is a relationship between inputs where each input is related to exactly one output.

x values can be ........-5,-4,-3,-2,-1, 0, 1, 2, 3, 4, 5, 6,.........

The reasonable domain for the function f(x) = 10x + 8 is (-∞, ∞).

A function is a relationship between inputs where each input is related to exactly one output.

Example:

f(x) = 2x + 1

f(1) = 2 + 1 = 3

f(2) = 2 x 2 + 1 = 4 + 1 = 5

The outputs of the functions are 3 and 5

The inputs of the function are 1 and 2.

We have,

f(x) = 10x + 8

We can have any real values of x.

f(-2) = -20 + 8 = -12

f(-1) = -10 + 8 = -2

f(1) = 10 + 8 = 18

f(2) = 20 + 8 = 28

f(3) = 30 + 8 = 28

.

.

x values can be ........-5,-4,-3,-2,-1, 0, 1, 2, 3, 4, 5, 6,.........

So,

The domain of the function f(x) = 10x + 8 is -∞ to ∞.

We can write as an interval as,

The reasonable domain for the function f(x) = 10x + 8 is (-∞, ∞).
