Step-by-step explanation:

the function

Kendal(x) = y = 90

is just a flat line (that's why people call it a flat rate). it does not matter how many hours it takes, it costs the same.

the function

Mona(x) = 10x + 70

as we know, $10 per hour, plus $70 for the material, which is the same cost no matter how many hours it takes.

the solution, when both cost the same, means again both functions are equal at that point :

90 = 10x + 70

20 = 10x

x = 20/10 = 2 hours

after 2 hours both cost the same : $90.

the graphic should look like the attached picture.

the flat line is at y = 90. that means it is a horizontal line that goes through the y gridline marker 90.

just draw the line along the y 90 gridline from left to right.

Mona's graph goes through the solution point (2, 90) and the point for x = 0 : (0, 70) because y = 10×0 + 70 = 70.

for (0, 70) you go from 0 the y-axis straight up to the gridline marker 70 and mark the point there.

for (2, 90) you go on the x-axis from 0 to the right to the gridline marker 2. from there you go straight up to the y gridline 90. and you mark the point there.

and both lines intersect at (2, 90), which is the solution.

can you see and understand it now how that works ?

The cost is $90

A graph can be defined as a pictorial representation or a diagram that represents data or values in an organized manner.

The function for Kendal(x) is:- y = 90

The function for Mona(x) :- 10x + 70

$10 per hour, plus $70 for the material

The solution, when both cost the same, means again both functions are equal at that point :

90 = 10x + 70

20 = 10x

x = 20/10 = 2 hours

after 2 hours both cost the same : $90.

Graph the lines both lines intersect at (2, 90), which is the solution.

Hence, the cost is $90

The functions f and g are inverse functions because f(g(x)) = g(f(x)) = x

From the question, we have the following parameters that can be used in our computation:

f(x) = x + 6

g(x) = x - 6

To determine the inverse function, we calculate

f(g(x)) and g(f(x))

Using the above as a guide, we have the following:

f(g(x)) = x + 6 - 6 = x

g(f(x)) = x + 6 - 6 = x

The proposition is false, and there exist nonnegative integers x that cannot be expressed as the sum of at most two squares and a cube of nonnegative integers.

This proposition is false. A counterexample is x = 7.

Assume for the sake of contradiction that there exist nonnegative integers a, b, and c such that x = a² + b² + c³. Since a² and b² are always nonnegative, we must have c³ ≤ 7. The only possible values for c are 0, 1, and 2, since 3³ = 27 > 7.

For c = 0, we have x = a² + b², which is the sum of two squares, and is a well-known result.

For c = 1, we have x = a² + b² + 1. However, it is a known result that a sum of two squares cannot be equal to a number of the form [tex]4^{k}[/tex](8m + 7) for some nonnegative integers k and m. Since 7 is of the form 4(8×0 + 7), it cannot be expressed as a sum of two squares, and therefore, x cannot be expressed as the sum of at most two squares and a cube of nonnegative integers.

For c = 2, we have x = a² + b + 8. Similarly, it can be shown that a sum of two squares cannot be equal to a number of the form [tex]4^{k}[/tex](8m + 7) for some nonnegative integers k and m. Since 8 is of the form 4(8×1 + 0), it cannot be expressed as a sum of two squares, and therefore, x cannot be expressed as the sum of at most two squares and a cube of nonnegative integers.

The average rate at which one quantity changes in relation to another's change is referred to as the average rate of change function.

A method that determines the amount of change in one item divided by the corresponding amount of change in another is known as an average rate of change function.

The average rate of change = f(b) - f(a) / b - a.

Given the following:

The function is: [tex]f(x) = 10\sqrt[3]{x}-5[/tex]

Interval is: x = 8 to x = 64

Therefore:

a = 8

b = 64

f(a) = f(8) =

[tex]f(x) = 10\sqrt[3]{8}-5\\\\f(x)=10*(2)-5\\\\f(x)=20-5\\\\f(x)=15[/tex]

f(a) = f(8) = 15

Because 1/5 is winning chance.

Answer:

Step-by-step explanation:

If we represent the first number as "x", then the second number can be represented as "2x-3".

For example, if the first number is 5, then the second number would be 2(5)-3 = 7.

Alternatively, if the first number is 10, then the second number would be 2(10)-3 = 17.

In general, we can say that the second number is equal to twice the first number minus 3.

A one-sample t-test can be used to determine whether the sample mean of M=115 is a particularly improbable outcome given the population parameters.

The test's null hypothesis is that the new treatment has no impact on extraversion, in which case the population mean remains at or above 100. The alternative theory is that the new treatment has an impact on extraversion, causing the population mean to deviate from the reference value of 100.

Using the following method, we can determine the test's t-statistic:

(M - ) / (s / sqrt(n)) t

Where M denotes the sample mean, denotes the population mean, s denotes the population standard deviation, and n denotes the sample number.

By entering the numbers we have:

t = (115 - 100) / (30 / sqrt(4)) = 3.33

The measure has n-1 = 3 degrees of freedom. We can use a calculator to determine the critical t-value, which is roughly 3.182, using a two-tailed t-test with alpha = 0.05 and 3 degrees of freedom.

The sample mean is a particularly improbable result based on the population parameters for the personality test because the calculated t-value of 3.33 is higher than the critical t-value of 3.182, and we can therefore reject the null hypothesis.

The evidence from the sample allows the researcher to draw the conclusion that the novel treatment has an impact on extraversion.

The expected number is 1, that means that if you randomly pick one ball and replace it with a blue ball, then you have a greater than 50/50 chance of eliminating all the red balls.

The expected number of blue balls needed to eliminate all red balls is calculated using the formula[tex]n = (x-1)/(y-1)[/tex]. In this scenario, x = 3 (the total number of balls in the box) and y = 2 (the number of red balls). Therefore, n = (3-1)/(2-1), which equals 1. So, the expected number of blue balls needed to eliminate all red balls is 1.

To illustrate this, imagine a box with 3 balls: 2 red and 1 blue. If you randomly pick one ball and replace it with a blue ball, then you have a 50/50 chance of eliminating all the red balls. If the ball you pick is red, then you need to pick another ball and replace it with a blue ball to get rid of the remaining red ball. This means that you need a total of 2 blue balls to get rid of all the red balls. However, since the expected number is 1, that means that if you randomly pick one ball and replace it with a blue ball, then you have a greater than 50/50 chance of eliminating all the red balls.

Mean '[tex]\bar{x}[/tex]' = 48.5 hours

Standard deviation 'σ' = 7.5 hours

Confidence interval = 88%

Level of significance = 100 - 88%

                                  = 12%

                                  = 0.12

Z-score at 88% confidence interval = 1.56

sample size 'n' = 51

Population standard deviation

= [tex]\bar{x}[/tex] ± [tex]Z_{\alpha /2}[/tex] (σ / √n )

= 48.5 ± 1.56 ( 7.5 / √51 )

The distance between the two planes after 10 minutes is 10 miles.

We can use the Pythagorean Theorem to find the distance between the two planes. According to the theorem, the distance between two points in a plane is given by the equation:

d = √( (x2 - x1)^2 + (y2 - y1)^2 )

where (x1, y1) and (x2, y2) are the coordinates of the two points.

The first plane is flying due north, so its position after 10 minutes will be (0, 10). The second plane is flying due east, so its position after 10 minutes will be (10, 0).

We can plug these coordinates into the equation to find the distance between the two planes:

d = √( (10 - 0)^2 + (10 - 0)^2 )

d = √( 100 )

d = 10

To subtract fractions, we need to have a common denominator. The smallest common denominator for 5 and 20 is 20, so we'll convert both fractions:

6 and 3/5 = 6 * 5/5 + 3/5 = 30/5 + 3/5 = 33/5

4 and 1/5 = 4 * 20/20 + 1/5 = 80/20 + 1/5 = 81/20

Now we can subtract:

33/5 - 81/20

We need to convert the mixed number to an improper fraction and find a common denominator:

33/5 - 81/20 = 132/20 - 81/20

Now we can subtract:

132/20 - 81/20 = 51/20

The correct initial value problem is: y'' + (9.81/0.75) y = 0, y(0) = -0.36, y'(0) = -0.45.

Here's how you can set up the initial value problem

Let y(t) be the displacement of the mass from its spring-mass equilibrium position at time t. Then, the force acting on the mass is given by Hooke's Law:

F = -ky

where k is the spring constant.

Since the mass is at rest at its equilibrium position, the force acting on it is balanced by the force of gravity.

mg = ky_eq

where y_eq is the equilibrium position of the spring-mass system.

Substituting F = -ky into the equation and solving for k, we get:

k = mg/y_eq

Substituting k and the values given, we get:

y'' + (9.81/0.75) y = 0

where y'' is the second derivative of y with respect to time.

When the mass is displaced 36 cm upward from its spring-mass equilibrium and then given a sharp downward tap, the initial conditions are:

y(0) = -0.36 m

y'(0) = -0.45 m/s (note that the velocity is downward, so it's negative)

Therefore, the initial value problem that models this experiment is:

y'' + (9.81/0.75) y = 0

y(0) = -0.36

y'(0) = -0.45
