Answer:

7 cups of water

Step-by-step explanation:

Divide 56 by 24

56/24 = 2 1/3

Multiply this by the cups of water wasted every 24 hrs

2 1/3 x 3 = 7

a. (0,0), (5,0), (3.75, 3.75), (3.5,4.5), (0,8);

b. x = 3.5, y = 4.5, OFV = 59.5;

c. s1 = 0, s2 = 2, s3 = 0.

a. The extreme points of the feasible region are the vertices of the polygon formed by the intersection of the constraint lines. In this case, the extreme points are (0,0), (5,0), (3.75, 3.75), (3.5,4.5), and (0,8).

b. To find the optimal solution and the objective function value, we evaluate the objective function at each extreme point and choose the point that maximizes the objective function. In this case, the point (3.5, 4.5) maximizes the objective function with a value of 59.5. Therefore, the optimal solution is x = 3.5 and y = 4.5, and the objective function value is 59.5.

c. The slack variables represent the surplus or slack in each constraint. We calculate the slack variables by subtracting the actual value of the left-hand side of each constraint from the right-hand side. In this case, the values of the slack variables are s1 = 0 (indicating no slack in the first constraint), s2 = 2 (indicating a surplus of 2 in the second constraint), and s3 = 0 (indicating no slack in the third constraint).

Therefore, the correct option is:

a. (0,0), (5,0), (3.75, 3.75), (3.5,4.5), (0,8);

b. x = 3.5, y = 4.5, OFV = 59.5;

c. s1 = 0, s2 = 2, s3 = 0.

Answer: It is A hope this helps :)

Step-by-step explanation:

The result x(t) = 13t is a solution of the differential equation dx/dt = kx where k = 1/t

In this question, we are given a differential equation dx/dt = kx.

This equation is called a first-order homogeneous linear differential equation.

This means that the highest derivative that appears in the equation is the first derivative, and there are no nonlinear terms.

The coefficient k is a constant that represents the rate at which the quantity x(t) changes with respect to time t.

Given the differential equation

dx/dt = kx

And,

x(t) = 13t is a solution

We need to find k.

In order to find the value of k, we differentiate the given solution with respect to time t and equate it to the given differential equation.

dx/dt = d/dt (13t)

= 13

Substituting the value of x and dx/dt in the differential equation, we get:

13 = k (13t)

⇒ k = 1/t

Therefore, k = 1/t.

Substituting the value of k in the given differential equation, we get:

dx/dt = (1/t) x .............................(1)

Now, let’s verify whether x(t) = 13t is a solution of the differential equation (1).

LHS of (1) = d/dt (13t)

= 13

RHS of (1) = (1/t) (13t)

= 13

Therefore, x(t) = 13t is a solution of the differential equation dx/dt = kx where k = 1/t

To find a particular solution of the differential equation, we are given that x(t) = 13t is a solution.

add decimal point

the 10's complement of 000000 is 999999.

The 10's complement of a number is given by subtracting each digit from 9.

Let us obtain the 10's complement of the given six-digit decimal numbers:123900

First, we need to subtract each digit of 123900 from 9:9 - 1 = 89 - 2 = 78 - 3 = 67 - 9 = 09 - 0 = 99 - 0 = 9

Therefore, the 10's complement of 123900 is 876100.090657

First, we need to subtract each digit of 090657 from 9:9 - 0 = 99 - 0 = 99 - 6 = 39 - 5 = 49 - 7 = 29 - 5 = 4

Therefore, the 10's complement of 090657 is 909343.100000

First, we need to subtract each digit of 100000 from 9:9 - 1 = 89 - 0 = 99 - 0 = 99 - 0 = 99 - 9 = 09 - 9 = 0

Therefore, the 10's complement of 100000 is 900000.000000

First, we need to subtract each digit of 000000 from 9:9 - 0 = 99 - 0 = 99 - 0 = 99 - 0 = 99 - 0 = 09 - 0 = 0

Therefore, the 10's complement of 000000 is 999999.

(a) P(z < -0.83) = 0.7967

(b) P(z > 1.07) = 0.1423

(c) If P(z > a) = 0.2033, then a = 0.84

To find the probabilities using the ∠-table (cumulative probabilities under the standard normal distribution), follow these steps:

(a) P(z < -0.83):

Look up the value -0.8 in the leftmost column of the table and the value 0.03 in the top row. The corresponding value in the table is 0.2033. Since the table provides values for positive z-scores, we can use the symmetry property of the standard normal distribution to find the desired probability:

P(z < -0.83) = 1 - P(z < 0.83) = 1 - 0.2033 = 0.7967

(b) P(z > 1.07):

Look up the value 1.0 in the leftmost column of the table and the value 0.07 in the top row. The corresponding value in the table is 0.8577. Since the table provides values for positive z-scores, we need to find the complement of the desired probability:

P(z > 1.07) = 1 - P(z < 1.07) = 1 - 0.8577 = 0.1423

(c) If P(z > a) = 0.2033, find the value of a:

Using the table, we find that the closest value to 0.2033 in the table is 0.20, which corresponds to a z-score of -0.84. Since we are interested in the upper tail, the desired value of a is the negative of the z-score:

a = -(-0.84) = 0.84

Therefore, the answers are:

(a) P(z < -0.83) = 0.7967

(b) P(z > 1.07) = 0.1423

(c) If P(z > a) = 0.2033, then a = 0.84

Para las siguientes fórmulas se tiene la siguiente notación:

\displaystyle I : Interés

\displaystyle C : Capital inicial

\displaystyle i : Tasa de interés

\displaystyle t : Tiempo

\displaystyle F : Capital final (o valor futuro)

Así, las fórmulas relacionadas con el cálculo de interés simple, cuando la tasa de interés y el tiempo utilizan la misma unidad de tiempo, son:

\displaystyle  I= C \cdot t \cdot i

\displaystyle  t=\frac{I}{C \cdot i}

\displaystyle C=\frac{I}{t \cdot i}

\displaystyle  i=\frac{I}{C \cdot t}

\displaystyle  F = C+I

In a binomial experiment with n trials and probability of success p, if n is large and/or p is close to 0.5, the binomial random variable X is approximately normal with μX = np and σX = sqrt(np(1-p)).

In a binomial experiment with n trials and probability of success p, if n is large and/or p is close to 0.5, the binomial random variable X is approximately normal with μX = np and σX = sqrt(np(1-p)). A binomial experiment involves a fixed number of independent trials (n) each having the same probability of success (p).The binomial distribution is a discrete probability distribution that describes the probability of success in a binomial experiment. When the sample size is large, the binomial distribution may be approximated by the normal distribution.This is because the normal distribution is continuous, whereas the binomial distribution is discrete. If the sample size is large enough, the binomial distribution can be well approximated by the normal distribution. For this approximation to work well, n should be large and p should be close to 0.5.When the binomial distribution is approximated by the normal distribution, the mean of the binomial distribution, which is np, is also the mean of the normal distribution. The standard deviation of the normal distribution is the square root of np(1-p).

In summary, when n is large and/or p is close to 0.5, the binomial random variable X is approximately normal with μX = np and σX = sqrt(np(1-p)).

The future value of the $10,000 investment after 7 years, at an interest rate of 6% per year, compounded annually, is approximately $14,185.10.

To calculate the future value (FV) of an investment of $10,000 at an interest rate of 6% per year, compounded annually, after 7 years, we can use the formula:

FV = P(1 + r)^n

Where:

P is the principal amount (initial investment) = $10,000

r is the interest rate per period = 6% = 0.06

n is the number of periods = 7

Plugging in the values, we have:

FV = $10,000(1 + 0.06)^7

Calculating the expression inside the parentheses first:

(1 + 0.06)^7 ≈ 1.41851

Now, multiply the principal amount by the calculated expression:

FV ≈ $10,000 * 1.41851 ≈ $14,185.10

Therefore, the future value of the $10,000 investment after 7 years, at an interest rate of 6% per year, compounded annually, is approximately $14,185.10.

Car Mart started with more cars. It started with 80 - 52 = 28 more cars than Winston's.

1. How many cars per day does Car Mart sell? To calculate the rate of decrease in the number of cars left, we can find the slope of the line connecting the points (0, 80) and (6, 20) on the graph. The slope is given by: Slope = (Change in y)/(Change in x) = (20 - 80)/(6 - 0) = -10 cars per day

Therefore, Car Mart sells 10 cars per day.2. How many cars per day does Winston's sell? We can use the information given to find the rate of decrease in the number of cars left at Winston's. Over a period of 2 days, the number of cars decreases from 32 to 12. Therefore, the rate of decrease is:

Rate of decrease = (32 - 12)/(3 - 5) = 10 cars per day

Therefore, Winston's sells 10 cars per day.3. Which dealership sells more cars per day? How many more? Car Mart sells 10 cars per day and Winston's sells 10 cars per day, so they sell the same number of cars per day.4. Which dealership started with more cars? How many more cars did that dealership start with?

To compare the number of cars each dealership started with, we can use the information given. After 3 days, Winston's has 32 cars left, which means it started with:

Number of cars Winston's started with = 32 + (10 x 2) = 52 carsAfter 0 days, Car Mart has 80 cars left, which means it started with: Number of cars Car Mart started with = 80 cars

Therefore, Car Mart started with more cars. It started with 80 - 52 = 28 more cars than Winston's.

Since the exponential function is always positive, there is no solution for e^(-2t) = -1/6. This means that the derivative is never equal to zero, and there is no point of maximum steepness for this curve.

To find the point at which the curve is steepest, we need to find the maximum value of the derivative of the function. Let's start by finding the derivative of the given function:

y = 50 / (1 + 6e^(-2t))

To find the derivative, we can use the quotient rule:

y' = [50(0) - (1 + 6e^(-2t))(-12e^(-2t))]/(1 + 6e^(-2t))^2

Simplifying this expression, we get:

y' = (72e^(-2t))/(1 + 6e^(-2t))^2

To find the maximum point, we need to find the value of t for which the derivative is equal to 0. Setting y' = 0 and solving for t, we have:

(72e^(-2t))/(1 + 6e^(-2t))^2 = 0

Since the numerator cannot be zero, we focus on the denominator:

(1 + 6e^(-2t))^2 = 0

Taking the square root of both sides, we get:

1 + 6e^(-2t) = 0

Solving for e^(-2t), we have:

e^(-2t) = -1/6

To solve the equation and find the radius, we need to rewrite it in the form of a circle equation, which is (x - h)² + (y - k)² = r², where (h, k) represents the center of the circle and r represents the radius.

Given equation: x² + y² + 2x - 10y + 8 = 8y - 46

To rewrite the equation in the form (x - h)² + (y - k)² = r², we complete the square for both the x and y terms:

[tex]\sf\:(x^2 + 2x) + (y^2 + 10y) = 8y - 46 - 8 \\[/tex]

Completing the square for x terms:

[tex]\sf\:x^2 + 2x = (x + 1)^2 - 1 \\[/tex]

Completing the square for y terms:

[tex]\sf\:y^2 + 10y = (y + 5)^2 - 25 \\[/tex]

Substituting the completed square forms into the equation:

[tex]\sf\:(x + 1)^2 - 1 + (y + 5)^2 - 25 + 8 = 8y - 46 - 8 \\[/tex]

Simplifying the equation:

[tex]\sf\:(x + 1)^2 + (y + 5)^2 = 8y - 46 - 8 + 1 + 25 - 8 \\[/tex]

[tex]\sf\:(x + 1)^2 + (y + 5)^2 = 8y - 36 \\[/tex]

Now we can see that the equation is in the form of (x - h)² + (y - k)² = r², where h = -1, k = -5, and r² = 8y - 36. Therefore, the radius is [tex]\sf\:\sqrt{8y - 36} \\[/tex].
