Answer:
The distance between the plane and the base of the airport = 103339.14 ft
Step-by-step explanation:
Consider the diagram attached.
We can notice that the a triangle (ABC) can be formed between the plane, the airport, and a vertical line drawn from the ground to the plane showing its altitude.
The angle of depression is 14 degrees. This means that angle BAC is 90 - 14 = 76 degrees.
From triangle laws, we will have that \(cos 76 = \frac{Altitude}{AC}\)
\(AC = \frac{25000}{(cos 76)} = 103339.14 ft\)
Hence, the distance between the plane and the base of the airport = 103339.14 ft
The diagonal distance between the plane and the base of the airport is 103339.14 ft.
This situation forms a right angle triangle.
The plane is flying at an elevation of 25000 ft.
The elevation is the height or opposite side of the triangle.
The diagonal distance between the plane and the base of the airport is the hypotenuse of the triangle.
Therefore, using trigonometric ratio,
sin 14° = opposite / hypotenuse
sin 14° = 25000 / d
d = 25000 / sin 14
d = 25000 / 0.2419218956
d = 103339.137361 ft
Therefore, the diagonal between the plane and the base of the airport is 103339.14 ft.

Use the formula to compute Isabel’s monthly loan payment, assuming that she makes a down payment of $5,000. Recall that the table shows she’ll finance $16,950, and her interest rate is 4. 3%.
Type the correct answer in the box. Round the answer to the nearest dollar.
Isabel’s monthly loan payment will be about $
Isabel's monthly loan payment will be about $270
The interest rate is 4.3%.
Isabel’s monthly loan payment will be about $270 , Isabel’s monthly loan payment, assuming that she makes a down payment of $5,000.
The formula for calculating a monthly payment for an amortized loan is given below:
P = (r × A) / (1 - (1 + r)⁻ⁿ)
Where,
P is the payment amount, r is the monthly interest rate, A is the loan amount, and n is the number of payments.Here, A = $16,950.
Isabel made a down payment of $5,000.
Therefore, her financed amount = $16,950 - $5,000
= $11,950.
The interest rate is 4.3%.
So, the monthly interest rate would be 4.3%/12 = 0.003583333.
Using these values in the formula, we get:
P = (0.003583333 * 11,950) / (1 - (1 + 0.003583333)⁻⁴⁸)P
≈ $270.
Hence, Isabel's monthly loan payment will be about $270 (rounded to the nearest dollar).

A graph of bell peper patch is given as below
Find:
we have to find the Maximum possible area of bell peper patch represented by the function p corresponding to the length of the tomato patch x.
Explanation:
From the given graph of function p(x), it is observed that the function has maximum value at x = 6.
Therefore, when x = 6, we get
\(\begin{gathered} p(6)=-0.5(6)^2+6(6) \\ p(6)=-0.5\times36+36 \\ p(6)=-18+36 \\ p(6)=18 \end{gathered}\)as the function p represents the area of the bell peper patch,
Therefore, Maximum possible area of the bell peper patch is p = 18 square feet, when the length of the zomato patch is x = 6 feet.

Farmer Jones and Farmer Smith graze their cattle on the same field. If there are 20 cows grazing in the field each cow produces $4000 of milk. If there are more cows in the field, then each cow produces can eat less grass and the milk production falls. With 30 cows on the field each produces $3000 of milk, with 40 cows each produces $2000 of milk . Cows cost $1000 a piece. Assume that Farmer Jones and farmer Smith can buy either 10 cows or 20 cows, find out the Dominant Strategy of Farmer Jones and express the same in formal language. I want to see all the steps.
The dominant strategy of Farmer Jones is to buy 10 cows.
To determine the dominant strategy of Farmer Jones, we need to compare the outcomes of his two options:
buying either 10 cows or 20 cows.
Let's analyze the potential outcomes for each case:
Buying 10 cows:
If Farmer Smith buys 10 cows:
The total number of cows in the field would be 30, resulting in each cow producing $3000 of milk.
If Farmer Smith buys 20 cows:
The total number of cows in the field would be 40, causing each cow to produce $2000 of milk.
Buying 20 cows:
If Farmer Smith buys 10 cows:
The total number of cows in the field would be 40, causing each cow to produce $2000 of milk.
If Farmer Smith buys 20 cows:
The total number of cows in the field would be 50, resulting in each cow producing less than $2000 of milk (exact value unknown).
From the given information, we can observe that regardless of the strategy chosen by Farmer Smith, Farmer Jones is better off buying 10 cows.
In all scenarios, the milk production per cow is higher when Farmer Jones buys 10 cows compared to buying 20 cows.
Therefore, the dominant strategy for Farmer Jones is to buy 10 cows.
Formally, we can express this as follows:
For Farmer Jones, no matter the strategy chosen by Farmer Smith, buying 10 cows yields a higher milk production per cow compared to buying 20 cows.
Hence, Farmer Jones' dominant strategy is to buy 10 cows.

two studies were done on the same set of data, where study a was a two-sided test and study b was a one-sided test. the p-value of the test corresponding to study a was found to be 0.040. what is the p-value for study b?
The p-value for study B is 0.98.
With the same set of data, two studies were conducted.
Study A was a two-sided test while study B was a one-sided test.
The p-value of the test in study A is 0.040.
If the test statistic from your sample has a negative value, the p-value for a two-sided test is equal to twice the p-value for the lower-tailed p-value. If the test statistic from your sample has a positive value, the p-value is two times that of the upper-tailed p-value.
So, in conclusion:
The one-tail p-value equals one minus half the two-tailed value.
The two-tail p-value is twice the one-tail p-value.
As study A is a two-sided test with p-value = 0.04.
The p-value of study B will be:
p = 1 - ( 1/2 ) × 0.04
p = 1 - 0.02
p = 0.98
The p-value for study B is 0.8.

find the net change in the value of the function between the given inputs. f(x) = 6x − 5; from 1 to 6
The net change in the value of the function between x = 1 and x = 6 is 30.
To find the net change in the value of the function between the inputs of 1 and 6, we need to find the difference between the output values of the function at x = 1 and x = 6, and then take the absolute value of that difference.
First, we can find the output value of the function at x = 1:
f(1) = 6(1) - 5 = 1
Next, we can find the output value of the function at x = 6:
f(6) = 6(6) - 5 = 31
The net change in the value of the function between x = 1 and x = 6 is the absolute value of the difference between these two output values:
|f(6) - f(1)| = |31 - 1| = 30
Therefore, the net change in the value of the function between x = 1 and x = 6 is 30.

the price of a jar of peanut butter went from $ 5.99 to $ 6.89 . what was the percent change in the price?
Using Percentage formula , The change in the price of a jar of peanut butter is 15.02%.
Percentage : It is defined as a relative value indicating hundredth parts of any quantity. One percent (symbolized 1%) is a hundredth part.
First of we need to calculate difference between initial price and final price to
get the change in price.
Initial Price of jar of peanut butter = $ 5.99
Final price of jar of peanut butter = $ 6.89
Change in price of a jar of peanut butter = final price of jar of peanuts butter - initial price of jar of peanuts butter
= $ 6.89 - $ 5.99 = $ 0.9.
Percent change in price = ((Change in Price)/(initial price))× 100
percent change = (0.9/5.99)× 100 = 15.02
Hence, 15.02% is the change in price of a jar of peanuts butter.

assume x and y are functions of t. evaluate for the following. y^3=2x^4 + 81 dx/dt = 4, x = 5, y = 11
dy/dt = ____
To find dy/dt, we can differentiate the given equation y^3 = 2x^4 + 81 with respect to t using implicit differentiation.
Differentiating both sides of the equation with respect to t, we get:
3y^2 * dy/dt = 8x^3 * dx/dt
Substituting the given values dx/dt = 4, x = 5, and y = 11 into the equation, we can solve for dy/dt:
3(11)^2 * dy/dt = 8(5)^3 * 4
363 * dy/dt = 8 * 125 * 4
363 * dy/dt = 4000

An isosceles triangle in which the two equal sides, labeled a, are longer than the base, labeled b.
This isosceles triangle has two sides of equal length, a, that are longer than the length of the base, b. The perimeter of the triangle is 15.7 centimeters. The equation can be used to find the side lengths.
If one of the longer sides is 6.3 centimeters, what is the length of the base?
cm
If one of the longer sides of the Isosceles triangle is 6.3 centimeters, the length of the base is 3.1 centimeters.
Let's solve the problem step by step:
1. Identify the given information:
- The triangle is isosceles, meaning it has two equal sides.
- The two equal sides, labeled "a," are longer than the base, labeled "b."
- The perimeter of the triangle is 15.7 centimeters.
- One of the longer sides is 6.3 centimeters.
2. Set up the equation based on the given information:
Since the triangle is isosceles, the sum of the lengths of the two equal sides is twice the length of the base. Therefore, we can write the equation:
2a + b = 15.7
3. Substitute the known value into the equation:
One of the longer sides is given as 6.3 centimeters, so we can substitute it into the equation:
2(6.3) + b = 15.7
4. Simplify and solve the equation:
12.6 + b = 15.7
Subtract 12.6 from both sides:
b = 15.7 - 12.6
b = 3.1
5. Interpret the result:
The length of the base, labeled "b," is found to be 3.1 centimeters.
Therefore, if one of the longer sides of the isosceles triangle is 6.3 centimeters, the length of the base is 3.1 centimeters.
