Answer:

  (x -10)²/64 +(y +8)²/100 = 1

Step-by-step explanation:

You want the equation of the ellipse with center (10,-8), a focus at (10, -14), and a vertex at (10, -18).

The length of the semi-major axis is the distance between the center and the give vertex: a = -8 -(-18) = 10 units.

The distance from the center to the focus is -8 -(-14) = 6.

The distance from the center to the covertex is the other leg of the right triangle with these distances as the hypotenuse and one leg.

  b = √(10² -6²) = √64 = 8 . . . . units

The equation for the ellipse with semi-axes 'a' and 'b' with center (h, k) is ...

  (x -h)²/b² +(y -k)²/a² = 1

  (x -10)²/64 +(y +8)²/100 = 1

__

Additional comment

The center, focus, and given vertex are all on the vertical line x=10, This means the major axis is in the vertical direction, and the denominator of the y-term will be the larger of the two denominators.

You will notice the center-focus-covertex triangle is a 3-4-5 right triangle with a scale factor of 2.

Step-by-step explanation:

The probability that the difference between the two numbers that appear will be less than 3 is 6/36 or 1/6.

There are 36 possible outcomes when two balanced dice are rolled, and 6 of those outcomes have a difference of less than 3. Thus, the probability of the difference between the two numbers being less than 3 is 6/36 or 1/6.

The probability of the difference between two numbers appearing when two balanced dice are rolled is determined by the number of possible outcomes that have a difference less than 3. Out of the 36 possible outcomes, 6 of them have a difference of less than 3, so the probability of the difference being less than 3 is 6/36 or 1/6.

The total cost of renting the electronic skateboard for 94 minutes is $23.53.

We are given that;

Rate for 47 minute= $1.74

Electronic skateboard= 20.05$

Now,

We can write an equation for the rent and the tax as follows:

r = 20.05 + 1.74 * (t / 47)

where r is the total cost of renting the electronic skateboard, t is the time in minutes, and x is the tax.

For example, if Aous wants to rent the electronic skateboard for 94 minutes, we can substitute t = 94 into the equation:

r = 20.05 + 1.74 * (94 / 47) = $23.53

Answer:    P(King AND King) = 1/221

Step-by-step explanation:

There are 4 Kings in a deck of 52 cards total

Probability of getting a King first time:

P(King) = 4/52                        > 4 Kings out of 52 total cards

P(King) = 1/13                          >reduced fraction by dividing top and

Probability of getting another king:

P(King) = 3/51                      > You took out a king so there are 3 left and 1

                                                 less to the total making 51

P(king) = 1/17                        >Reduced by dividing top and bottom by 3

Probability of getting king and then king again.  The second king is dependent on you getting a king the first time.  Because it is dependent, you multiply the 2 probabilities

P(King AND King) = (1/13)(1/17)

Step-by-step explanation:

We know that in order to work out the area of rectangle we have to apply the formula length × width. In this scenario we are given the area and the length and we are asked to find the width so,

Area of a rectangle = Length × Width

→ Substitute in the values

88 = 8 × Width

→ Divide both sides by 8 to isolate the width

11 = Width

Answer:

11 - width

Step-by-step explanation:

To find the area of a rectangle, this is the formula:

area = length × width

So to find the width you need to rearrange the formula to make:

Width= length / area

8 / 88 = 11

/ = divide

The linear representation is a proportional relationship.

What is proportional relationship?

Proportional relationships are those in which the ratios of the two variables are equal. Another way to think about them is that one variable is always a constant value multiplied by the other in a proportionate relationship. The "constant of proportionality" is the name given to this variable.

We know that in a proportional relationship the ratios are equal i.e.

\(\frac{y_{1}}{x_{1} } = \frac{y_{2} }{x_{2} } =\frac{y_{n} }{x_{n} }\)

So,

-16/4 = -12/3 = -8/2 = -4/1 = -4

Since, the ratios of the linear representation are equal, therefore, it is a  proportional relationship.

Hence, the linear representation is a proportional relationship.

Step-by-step explanation:

Empirical likelihood estimation is a statistical method used to estimate the parameters of a probability distribution based on observed data. It relies on the principle of maximizing the empirical likelihood function, which measures the likelihood of the observed data given certain constraints.

When auxiliary summary information is available, such as covariate distributions, empirical likelihood estimation can incorporate this information to improve the estimation process. The use of different covariate distributions allows for a more flexible modeling approach.

By incorporating auxiliary covariate distributions, empirical likelihood estimation can capture additional information about the relationship between the covariates and the response variable. This approach can lead to more efficient and accurate parameter estimates, especially when the covariates have a strong influence on the response variable.

The choice of covariate distributions depends on the specific problem and the nature of the data. Researchers can select appropriate distributions based on prior knowledge, expert opinion, or exploratory analysis. Using different covariate distributions allows for a wider range of modeling possibilities and can capture various patterns and relationships in the data.

By leveraging auxiliary summary information and incorporating different covariate distributions, empirical likelihood estimation provides a flexible and powerful method for parameter estimation. It enables researchers to make more informed and precise inferences about the underlying population based on the observed data and the additional auxiliary information.

Here's the complete question:

It cost Nike $55.00 to make the Kyrie 5, but it is selling for $130.19. Calculate the markup/percent Increase for the shoe. On Amazon, you found the same shoe for $108. What is the percent difference between the price of the original shoe and the price of the amazon shoe

The percentage Increase of the shoe will be:

= Selling price - Cost/ Cost × 100

= (130.19 - 55.00) / 55.00 × 100

= 75.19 / 55.00 × 100

= 136.71%

The percent difference between the price of the original shoe and the price of the amazon shoe will be:

= (130.19 - 108)/130.19 × 100

= (22.19 / 130.19) × 100

= 17%

Step-by-step explanation:

Caroline leaves her house and walks north 6 blocks. She turns and heads east 8 blocks until she reaches mattie’s house.

The shortest distance between Caroline’s and Mattie’s house is 10 blocks.

If we assume this as a right angle triangle then height(BA) is 6 blocks long and base(BC) is 8 blocks

long.

Then, the shortest distance between Caroline’s and Mattie’s house will be the hypotenuse(AC) of this

triangle.

So, by applying Pythagoras theorem:

(AC)² = (BA)² + (BC)² = (6)²+(8)² = 36+64 = 100

Thus, AC = √100 = 10 block

The cost of walking this guest is $190.

The cost of walking the guest can be calculated by adding up the expenses incurred by the hotel.

The guest was walked to another hotel that charged a room rate of $150. Therefore, the hotel incurred a cost of $150 for the room.

In addition to the room cost, the hotel also paid for the guest's Uber ride to the new hotel, which was $15.

Furthermore, the overbooked hotel gave the guest a gift card worth $25. Although the gift card does not directly represent an expense, it can be considered as an opportunity cost for the hotel, as they could have used that money to cover other costs.

Therefore, the total cost incurred by the hotel for walking the guest is:

Step-by-step explanation:

sorry cant help

The function g(t) is -cos(t), and g(0) = -1. The correct option is g(0) = -cos(t)

To transform the integral ∫ sin(x - 2) dx using an appropriate change of variable, let's set t = x - 2. This implies that dt = dx.

When x = 2, t = 2 - 2 = 0, and when x approaches infinity, t also approaches infinity.

Now we can rewrite the integral as:

∫ sin(t) dt

This integral can be evaluated as follows:

∫ sin(t) dt = -cos(t) + C

Therefore, the integral ſ sin(x - 2) dx, transformed using the appropriate change of variable, becomes:

L.9(t) = -cos(t) + C

Hence, the function g(t) is:

g(t) = -cos(t)

Additionally, we have g(0) = -cos(0) = -1.

Therefore, the correct option is: g(0) = -cos(t).

The given initial value problem's exact solution: y(t) = 1, and thus y(1) = 1. The Euler approximation of y(1) using a step-size h = 0.5 i: y(1) ≈ 1. Given the initial value problem:

y' = ty ' (0)

 = 0

We are to determine the exact solution y(t) and compute y(1), and also find the Euler approximation of y on the interval [0, 1] using a step-size h = 0.5 (half step size).

(a) The given initial value problem is a first-order linear differential equation, whose standard form is:

y' + P(t)y = Q(t), where P(t) = 0 and Q(t) = 0. Thus, the integrating factor is:

I(t) = e^∫ P(t)dt

      = e^∫ 0 dt

      = 1.

The exact solution y(t) is obtained by multiplying both sides of the differential equation by the integrating factor,

I(t) = 1, and integrating:

y' + P(t)y = Q(t) becomes

y' + 0y = 0, which implies

y' = 0.

Hence, y(t) = Ce^0 = C, where C is a constant determined using the initial condition y(0) = 1. Therefore, we have:

C = y(0) = 1.

Hence, the initial value problem's exact solution is y(t) = 1, and thus y(1) = 1.

(b) Euler Approximation of y using step-size h = 0.5We have h = Δt = 0.5, t0 = 0, tn = 1. The number of steps, n, is given by:

n = (tn - t0)/h

n = (1 - 0)/0.5

n = 2.

Therefore, we have two grid points:

t0 = 0, and

t1 = 0 + 0.5

  = 0.5

For the Euler approximation of y on [0, 1], we use the formula:

yi+1 = yi + h * f(ti, yi), for i = 0, 1, 2, ..., n - 1, where

f(ti, yi) = tiyi

= (0)(yi)

= 0, for i = 0, 1, 2, ..., n - 1.

Hence, we have:

y0 = y(0) = 1, and

y1 = y0 + h * f(t0, y0)

= y0 + h * 0

= 1 + 0

= 1

Therefore, the Euler approximation of y(1) using a step-size h = 0.5 is: y(1) ≈ y1 = 1. Therefore, y(1) ≈ 1. The exact solution of the given initial value problem is: y(t) = 1, and thus y(1) = 1. The Euler approximation of y(1) using a step-size h = 0.5 is: y(1) ≈ 1.
