Answer:
Part A: 8/3 square inches or 2.667 square inches is the area used for peas (remember to label)
Part B: $8 for selling the peas for $3
Step-by-step explanation:
1.) To find the amount of space she uses for peas, multiply 10,2/3 (or 32/3) by 1/4. (1/4)x(32/3)=8/3. That's the area for part A
2.) (8/3)x3=8. She would make $8

Round answer to two digits after the decimal point. Suppose I need to borrow \$1,709 from my neighbor The Saver. The Saver charges 182% simple annual interest rate and I have to pay the principal plus interest off in 16 equal monthly payments. How much will be the monthly payment amount? Round answer to two digits after the decimal point.
Answers
The 18th term of the arithmetic sequence is 45.2, while the balance in an account with a $8,600 deposit and 12% annual interest after 5 years is $14,311.39. With a $6,284 deposit and 14% annual interest after 30 months, the account balance will be $7,463.17. Borrowing $1,709 at a 182% annual interest rate, the monthly payment for 16 months will be $202.06.
1. Arithmetic sequence: The formula to find the nth term of an arithmetic sequence is given by:
nth term = first term + (n - 1) * common difference
Here, the 4th term is given as 6 and the common difference is 2.9. Plugging in these values, we can calculate the 18th term as follows:
18th term = 6 + (18 - 1) * 2.9 = 6 + 17 * 2.9 = 45.2
2. Compound interest: For the first scenario, where $8,600 is deposited into an account that pays 12% simple annual interest compounded monthly for 5 years, we can calculate the final balance using the formula for compound interest:
A = P * \((1 + r/n)^{(n*t) }\)
Here, P is the principal amount, r is the annual interest rate (in decimal form), n is the number of times interest is compounded per year, and t is the number of years. Plugging in the values:
P = $8,600, r = 12% = 0.12, n = 12 (monthly compounding), t = 5
A = 8600 * \((1 + 0.12/12)^{(12*5)}\)= $14,311.39
3. Similarly, for the second scenario, where $6,284 is deposited into an account that pays 14% simple annual interest compounded monthly for 30 months:
P = $6,284, r = 14% = 0.14, n = 12 (monthly compounding), t = 30/12 = 2.5
A = 6284 * \((1 + 0.14/12)^{(12*2.5)}\) = $7,463.17
4. Monthly payment: To calculate the monthly payment amount for borrowing $1,709 from The Saver at a 182% simple annual interest rate, we can divide the total amount by the number of payments. The formula for calculating the monthly payment for a loan is:
Monthly payment = Total amount / Number of payments
Here, the total amount is $1,709 and the number of payments is 16. Plugging in the values:
Monthly payment = 1709 / 16 = $202.06

Let f(x) = 9x^2 -2x . Compute and simplify f(x + h) - f(x) / h
, for h ≠ 0
Answers
The given function is, f(x) = 9x² - 2x.
The computation of f(x + h) - f(x)/h for h ≠ 0 is as follows:
Step 1:
Firstly, f(x + h) will be calculated f(x + h) = 9(x + h)² - 2(x + h) = 9(x² + 2xh + h²) - 2x - 2h
Step 2:
f(x) will be calculated as:f(x) = 9x² - 2x
Step 3:
Now, compute the difference between the two functions:
f(x + h) - f(x) = [9(x² + 2xh + h²) - 2x - 2h] - [9x² - 2x] = 18xh + 9h²
Step 4:
we will simplify f(x + h) - f(x)
As shown below:
f(x + h) - f(x) = 18xh + 9h²
Step 5:
Then, divide by h, we get:(f(x + h) - f(x))/h = (18xh + 9h²)/h = 18x + 9h
The value of f(x + h) - f(x) / h for h ≠ 0 is 18x + 9h.

Answers
After answering the presented question, we can conclude that As a trigonometry result, the helicopter is approximately 2,309 feet above land.
what is trigonometry?The study of the relationship between triangle side lengths and angles is known as trigonometry. Owing to the application of geometry in astronomical research, the topic initially originated in the Hellenistic era, beginning in the third century BC. The subject of mathematics known as exact techniques deals with certain trigonometric functions and their potential applications in computations. There are six commonly used trigonometric functions in trigonometry. Sine, cosine, tangent, cotangent, secant, and cosecant are their separate names and acronyms (csc). The study of triangle properties, particularly those of right triangles, is known as trigonometry. As a result, geometry is the study of the properties of all geometric shapes.
To begin, we must determine the length of the two legs of the right triangle. Let's begin with Amanda's perspective:
tan(60°) = h / x
tan(60°) = h / 2000
h = 2000 tan(60°)
h = 3464.1 ft (rounded to the closest foot) (rounded to the nearest foot)
tan(30°) = h / (4000 - x) (4000 - x)
tan(30°) = h / 2000
h = 2000 tan(30°)
h = 1154.7 ft (rounded to the closest foot) (rounded to the nearest foot)
Because we have two distinct heights for the same aircraft, we must average them to obtain the ultimate height:
(3464.1 + 1154.7) / 2 = (h for Amanda + h for Jeremiah) / 2
h = 2309.4 ft (rounded to the closest foot) (rounded to the nearest foot)
As a result, the helicopter is approximately 2,309 feet above land.

describe a linear program whose solution describes the largest axis-aligned square that lies entirely inside p.
Answers
To describe a linear program for finding the largest axis-aligned square that lies entirely inside a polygon (p), we can define the decision variables, objective function, and constraints as follows:
Decision Variables:
Let x be the side length of the square.
Objective Function:
Maximize x. The objective is to find the largest possible side length for the square.
Constraints:
Square Within Polygon Constraint:
For each vertex (xᵢ, yᵢ) of the polygon p, we can define the following set of inequalities:
xᵢ ≤ x, for all vertices of the polygon.
These inequalities ensure that the square lies entirely within the polygon.
Square Symmetry Constraint:
To ensure that the square is axis-aligned, we can impose symmetry constraints. For example, if the coordinates of the center of the square are (c_x, c_y), then we can add the following constraints:
c_x ± (x/2) = constant, for fixed values of c_x.
c_y ± (x/2) = constant, for fixed values of c_y.
These constraints ensure that the sides of the square are parallel to the x and y axes.
Non-Negative Constraint:
x ≥ 0, to ensure a non-negative side length for the square.
By formulating and solving this linear program, we can find the optimal value for x, which represents the largest axis-aligned square that lies entirely within the given polygon p.

The graph represents the relationship between the temperature and hours after sunrise. The slope shows the temperature changes per hour and the y-intercepts shows the temperature at the time of sunrise. The linear equation of this condition is y = 4x + 4.
From the graph, we can get some informations:
The temperature at the time of sunrise is 4 degrees celcius. This information is represented by the y-intercepts on 4 or point (0, 4). This is the initial temperature of the day.
Next, we will try to find the slope of the graph. We take 2 points:
(0, 4)
(1, 8)
Slope (m) = y₂ - y₁
x₂ - x₁
m = (8 - 4)
(1 - 0)
m = 4
However, as the hour goes by, the temperature increases by 4 degrees celcius. This information is known based on the slope of the graph. The slope represents the degree celcius of temperature change per hour.
Based on the found y-intercepts and slope, we can formulated the linear equation of the graph as:
y = 4x + 4
where:
y = temperature
x = hours after sunrise

when can a correlation coefficient based on an observational study be used to support a claim of cause and effect?
Answers
A correlation coefficient based on an observational study cannot be used to support a claim of cause and effect, as correlation does not imply causation.
Correlation is a statistical measure that describes the strength and direction of a relationship between two variables. A correlation coefficient ranges from -1 to 1, where -1 indicates a strong negative correlation, 0 indicates no correlation, and 1 indicates a strong positive correlation. Correlation does not imply causation, meaning that just because two variables are correlated does not mean that one causes the other.
In an observational study, researchers observe and record data on variables of interest without manipulating them directly. These studies are often used in fields such as epidemiology, social sciences, and psychology to investigate relationships between variables and identify potential risk factors for diseases or other outcomes.
Observational studies can suggest possible relationships between variables, but they cannot prove causation. This is because there may be other factors that are influencing the relationship between the variables, and these factors cannot be controlled or accounted for in an observational study. In order to establish causation, researchers need to conduct experiments where they can manipulate the variables and control for other factors that may influence the outcome.
Therefore, a correlation coefficient based on an observational study cannot be used to support a claim of cause and effect, as correlation does not imply causation.
