MODELING REAL LIFE The fence surrounding a rectangular giraffe exhibit needs to be replaced. The exhibit covers a
total area of 2500 square feet. The zoo wants to change the dimensions of the exhibit to minimize the amount of fencing
needed without reducing the exhibit's area. What should the new dimensions be so the exhibit is still rectangular?
Explain. (See Example 3.)

Answers

Answer 1

Answer:

50 ft. × 50 ft.

Step-by-step explanation:

Let's assume that the rectangular exhibit has a length of 'L' and a width of 'W'. The area of the exhibit is given as 2500 square feet, so we have:

L × W = 2500

We want to change the dimensions of the exhibit to minimize the amount of fencing needed while keeping the same area. The amount of fencing needed is directly proportional to the perimeter of the exhibit. The perimeter of a rectangular exhibit is given as:

P = 2L + 2W

We want to minimize P while keeping the area constant. One way to do this is to use the area formula to express one of the variables in terms of the other and then substitute it in the perimeter formula.

From the area formula, we have:

L × W = 2500

W = 2500 / L

Substituting W in the perimeter formula, we get:

P = 2L + 2(2500 / L)

Simplifying, we get:

P = 2L + 5000/L

To minimize P, we can take the derivative of P with respect to L and set it to zero:

dP/dL = 2 - 5000/L² = 0

Solving for L, we get:

L² = 2500

L = 50

Substituting L in the equation for W, we get:

W = 2500 / L = 50

Therefore, the new dimensions of the rectangular giraffe exhibit should be 50 feet by 50 feet to minimize the amount of fencing needed while keeping the same area.

Find an equation of the circle that satisfies the stated conditions. (Give your answer in standard notation.)

Tangent to both axes, center in the second quadrant, radius 4

Answers

Answer:

[tex](x+4)^2+(y-4)^2=16[/tex]

Step-by-step explanation:

A tangent is a straight line that touches a circle at only one point.

Since the circle is tangent to both axes, and the center of the circle is in the second quadrant, the center of the circle lies on the line y = -x.

As the circle is tangent to the x-axis, the distance between the center of the circle and the x-axis is equal to the radius of the circle.

Similarly, as the circle is tangent to the y-axis, the distance between the center of the circle and the y-axis is also equal to the radius of the circle.

Therefore, the center of the circle will be 4 units to the left of the y-axis and 4 units up from the x-axis. Therefore, the coordinates of the center are (-4, 4).

[tex]\boxed{\begin{minipage}{5 cm}\underline{Equation of a circle}\\\\$(x-h)^2+(y-k)^2=r^2$\\\\where:\\ \phantom{ww}$\bullet$ $(h, k)$ is the center. \\ \phantom{ww}$\bullet$ $r$ is the radius.\\\end{minipage}}[/tex]

Substitute the center (-4, 4) and the radius, r = 4, into the standard equation of a circle:

[tex]\implies (x - (-4))^2+(y-4)^2=4^2[/tex]

[tex]\implies (x+4)^2+(y-4)^2=16[/tex]

Therefore, the equation of the circle that satisfies the given conditions is:

18. Floyd decides to invest $1,000,000 in a 20-year annuity that earns 4.6% APR
compounded monthly. How much money will Floyd be paid each month from this annuity?

Answers

The amount that Floyd will be paid each month from this annuity is $6,374.83 each month.

How do we determine the monthly payment?

To calculate the monthly payments from a 20-year annuity with an initial investment of $1,000,000 at an APR of 4.6% compounded monthly, we can use the formula for calculating the monthly payment of an ordinary annuity: Monthly Payment = P * r * (1 + r)^n / ((1 + r)^n - 1)

Data

P = $1,000,000)

r = 4.6% / 12 / 100 = 0.00383

n = = 20 * 12 = 240

Plugging in the values. The monthly payment will be:

= $1,000,000 * 0.00383 * (1 + 0.00383)^240 / ((1 + 0.00383)^240 - 1)

= $1,000,000 * 0.00383 * 1.66538674279

= $6,378.43122

= $6,378.43

Answers

Max and Pam will be able to spend $676.1 on their trip.

What is the balance after 3 years?

The formula accrued amount in a compounded interest is expressed as;

A = P( 1 + r/n )^( n × t )

Where A is accrued amount, P is principal, r is interest rate and t is time.

Given the data in the question;

Principal P = $600.00

Compounded quarterly n = 4

Time t = 3  years

Interest rate r = 4%

Accrued amount A = ?

First, convert R as a percent to r as a decimal

r = R/100

r = 4/100

r = 0.04 rate per year.

Plug the given values into the above formula and solve for A.

A = P( 1 + r/n )^( n × t )

A = $600( 1 + 0.04/4 )^( 4 × 3 )

A = $600( 1 + 0.01 )^( 12 )

A = $600( 1.01 )^( 12 )

A = $676.1

A bakery charges $4.50 per delivery,
plus $0.40 per mile. Which table

Answers

The table which most accurately reflects the relationship between the distance traveled and the total cost is table D.

Given that,

A bakery charges $4.50 per delivery, plus $0.40 per mile.

The relationship is between the distance traveled and the total cost.

This is a linear relationship.

Slope = 0.4

Since delivery charge is fixed, we can write the equation as,

y = 0.4x + 4.5, where y is the total cost and x is the distance travelled.

When x = 2, y = (0.4 × 2) + 4.5 = 5.3

When x = 3, y = (0.4 × 3) + 4.5 = 5.7

When x = 7, y = (0.4 × 7) + 4.5 = 7.3

When x = 8, y = (0.4 × 8) + 4.5 = 7.7

Hence the correct option is D.

For what value of c is the number "a" a solution of the equation?
4x + 1 + 7c = 6c - 3x + 6; a = -6

c =

Answers

Answer:

c = 47

Step-by-step explanation:

The solution of the equation is the value of x.

Given "a" is a solution of the equation, and a = -6, to find the value of c, substitute x = -6 into the given equation and solve for c.

⇒ 4x + 1 + 7c = 6c - 3x + 6

⇒ 4(-6) + 1 + 7c = 6c - 3(-6) + 6

⇒ -24 + 1 + 7c = 6c + 18 + 6

⇒ -23 + 7c = 6c + 24

⇒ -23 + 7c - 6c = 6c + 24 - 6c

⇒ -23 + c = 24

⇒ -23 + c + 23 = 24 + 23

⇒ c = 47

Therefore, the value of c that makes a = -6 a solution of the equation is 47.

Final answer:

The value of 'c' for which 'a' is a solution of the given equation can be found by substituting 'a' into the equation and simplifying. In this case, 'a' is -6, and by substituting this value into the equation and simplifying, we find that when 'c' is 47, 'a' becomes a solution.

Explanation:

To find the value of c for which a is a solution of the equation, we have to substitute the value of a into the equation and solve for c. Here, a = -6, which means x can be considered as -6 in the equation.

Step 1: Substitute the value of a (x) into the equation. So the equation 4x + 1 + 7c = 6c - 3x + 6 becomes 4(-6) + 1 + 7c = 6c - 3(-6) + 6.

Step 2: Simplify both sides of the equation. We get -24 + 1 + 7c = 6c + 18 + 6.

Step 3: Continue simplifying to -23 + 7c = 6c + 24.

Step 4: By rearranging terms, we find c = 47.

If 7π/12= 9π/ 12 - 2π/12, evaluate sin 7π/12

Answers

The requried solution of the given trigonometric function is sin7π/12 is  (√3 + 1)/(2√2).

We know that 7π/12 = 9π/12 - 2π/12.

So, we can rewrite sin(7π/12) as sin(9π/12 - 2π/12).

Using the trigonmetric identity,
sin(A - B) = sinAcosB - cosAsinB, we can rewrite sin(9π/12 - 2π/12) as sin(9π/12)*cos(2π/12) - cos(9π/12)*sin(2π/12).

We know that,
sin(2π/12) = sin(π/6) = 1/2 and cos(2π/12) = cos(π/6) = √3/2.

Also, sin(9π/12) = sin(3π/4) = 1/√2 and cos(9π/12) = cos(3π/4) = -1/√2.

Substituting these values, we get:

= sin(7π/12) = sin(9π/12 - 2π/12)

= sin(9π/12)cos(2π/12) - cos(9π/12)sin(2π/12)

= (1/√2)(√3/2) - (-1/√2)(1/2)

= (√3/2√2) + (1/2√2)

= (√3 + 1)/(2√2)

Bus 47, with an IQR of 24
Bus 18, with a range of 16
Bus 47, with a range of 24

Answers

Answer:

Please help me by marking me brainliest

Step-by-step explanation:

To determine which bus is the most consistent, we need to compare the measures of variability for each data set.

The range is the simplest measure of variability, and it is calculated by subtracting the minimum value from the maximum value in the data set. From the given line plots, we can see that Bus 18 has a range of 16 (from 6 to 22), while Bus 47 has a range of 24 (from 4 to 28). Therefore, Bus 18 has a smaller range, which might suggest that it is more consistent.

However, the interquartile range (IQR) is a better measure of variability, as it is less sensitive to extreme values. The IQR is calculated by subtracting the first quartile (Q1) from the third quartile (Q3) of the data set.

From the given line plots, we can see that Bus 18 has an IQR of 16 (from Q1=10 to Q3=26), while Bus 47 has an IQR of 24 (from Q1=6 to Q3=30). Therefore, Bus 18 has a smaller IQR, which indicates that it is more consistent than Bus 47.

In conclusion, we can determine that Bus 18 is the most consistent based on its smaller IQR. This means that the travel times for Bus 18 students are more tightly clustered around the median than the travel times for Bus 47 students.

Final answer:

Using the measures of variability, it can be concluded that Bus 18 is the most consistent because it has a lower Interquartile Range (IQR) and a lower range in its times.

Explanation:

The most consistent bus can be found by using measures of variability, specifically the range and the interquartile range (IQR). The range is the difference between the highest and lowest values, while the IQR represents the middle 50% of data. In this case, the range of Bus 47 is 24 (28-4) and that of Bus 18 is 16 (22-6). Similarly, the IQR of Bus 47 is 12 (22-10) and 8 for Bus 18 (16-8).

A lower IQR and range indicate more consistency, as the data points are closer together. Therefore, Bus 18 is the most consistent in terms of travel times as it has both a lower range and a lower IQR.

So, let's first figure out the fractional value of the water added. We can accomplish this by taking the resulting amount and subtracting the initial amount of water.

3/6 - 1/6 = 2/6

2 gallons = 2/6 of the tank

Next, let's figure out how many gallons will fill 1/6 of the tank.

2 gallons = 2/6 of the tank

1 gallon = 1/6 of the tank

Now that we know how many gallons 1/6 of the tank is, we can figure out how many gallons 6/6 of the tank is.

Country G decides to reduce their $18.5 billion debt by a decay factor of 0.995 each year. This can be modeled by the
equation A 18.5(0.995). Estimate the debt after 15 years. Round to the nearest hundredth and do not round until the
final calculation.
Provide your answer below:

Answers

Rounding to the nearest hundredth, the debt of Country G after 15 years would be approximately $14.89 billion dollars.

How to solve the question?

The given equation for the debt of Country G is A = 18.5(0.995), where A represents the debt after one year, and the factor of 0.995 represents the decay factor. To estimate the debt after 15 years, we can use this equation iteratively.

After the first year, the debt would be A = 18.5(0.995) = 18.4 billion dollars. To find the debt after the second year, we can use the same equation, but replace the initial debt of 18.5 billion dollars with the debt after one year, which is 18.4 billion dollars. Therefore, the debt after two years would be A = 18.4(0.995) = 18.3 billion dollars.

We can repeat this process for each subsequent year, using the previous year's debt to calculate the next year's debt. After 15 years, the debt would be:

A = 18.5(0.995)¹⁵

A = 18.5(0.80424)

A = 14.8866 billion dollars

Rounding to the nearest hundredth, the debt of Country G after 15 years would be approximately $14.89 billion dollars.

It's important to note that this estimate assumes that the decay factor remains constant over the 15-year period. In reality, economic and political factors could impact the decay rate and the actual debt of Country G.

The diagonal splits the rectangle into two right triangles so we can use Pythagorean theorem to find the length of the missing side.

Pythagorean theorem states that a^2 + b^2 = c^2 where c is the hypotenuse and a and b are the other two sides

So we can label our unknown side as x

x^2 + 9^2 = 18^2

x^2 + 81 = 324

Subtract 81 from both sides to isolate the x

x^2 = 243

Find the square root of both sides

√x^2 = √243

x ≈ 15.6

(The instruction said round to the nearest 10th).

So now we know

l = 15.6m and w = 9m

P= 2l + 2w

A= lw

P= 2(15.6) + 2(9)

P= 31.2 + 18

P= 49.2m

A=15.6(9)

A=140.4m^2

A. Mean: This measure of central tendency signifies the average value in a dataset, derived by summing each data point and dividing by total quantity.

How to explain the terms

B. Median: An indicator of central tendency is utilized to discern the middle value for a given set. Primarily, the tabulated elements must be listed from least to greatest before arriving at the average between two centermost figures if the number of components is even.

C. Mode: As an analysis concerning where centrality lies, this technique seeks out the most regularly occurring element in a gathered dataset.

D. Range: The range serves as an assessment of variability measured via the differences between the upper and lower bounds registered within the collection. To calculate, subtract the minimum value from the maximum quota.

E. Interquartile range: Better known as IQR, this method measuring disparity quantifies dissimilarities between the 75th percentile (Q3) and 25th percentile (Q1). To ascertain, subtract Q1 from Q3. Such information is often used to pinpoint irregularities and evaluate the discrepancies among separate datasets.

The value of standard deviation 's' is 2.08700, as indicated in the display.

What is standard deviation?

Standard deviation is a measurement of how evenly distributed a set of numbers is. Since the variance is the average of the squared deviations from the mean, it is the square root of the variance.

The value of s is 2.08700, as indicated in the display.

The symbol "Sx" represents the sample standard deviation, which is commonly denoted as "s". The other values in the display are:

t = -0.483735: the t-statistic for the hypothesis testp = 0.315322: the p-value for the hypothesis testoverbar(x) = 39.86: the sample meann = 52: the sample size

So, the correct answer is 2.08700.

For a confidence level of 80% with a sample size of 11, find the critical t value.

Answers

Answer:

To find the critical t-value for a confidence level of 80% with a sample size of 11, we need to consult a t-distribution table or use a statistical software.

Using a t-distribution table with 10 degrees of freedom (sample size - 1), we can find the critical t-value for a two-tailed test at a confidence level of 80%.

From the table, we find that the critical t-value is approximately 1.363.

Therefore, the critical t-value for a confidence level of 80% with a sample size of 11 is approximately 1.363.

The average wingspan of monarch butterflies at a butterfly preserve is 8.5 centimeters with a stan deviation of 0.4 centimeter. If the wingspans are normally distributed, what is the probability, to t nearest hundredth, that monarch butterflies have a wingspan longer than 8.8 centimeters?

Answers

If the average wingspan of monarch butterflies at a butterfly preserve is 8.5. the probability, to t nearest hundredth, that monarch butterflies have a wingspan longer than 8.8 centimeters is : 0.23.

How to find the probability?

First step is to standardize the value of 8.8 centimeters using the z- score  formula:

z = (x - mu) / sigma

where:

x  = wingspan

mu = mean wingspan

sigma= standard deviation

z  standardized score

Substituting the given values

z = (8.8 - 8.5) / 0.4

z = 0.75

So,

P(z > 0.75) = 1 - P(z <= 0.75)

Using a standard normal distribution table  P(z <= 0.75) = 0.7734

P(z > 0.75) = 1 - P(z <= 0.75)

= 1 - 0.7734

= 0.2266

= 0.23 (  Approximately)

Therefore the probability is 0.23.
