When you were born, your parents opened an investment account in your name and deposited $500 into the account. The account has earned an average annual rate of return of 10 percent compounded monthly. Today, the account is valued at $36,911.22. How old are you? a. 46 years old b. 35 years old c. 32 years old d. 43 years old
\((36911.22/500) = 12x ln(1 + r)ln(36911.22/500) = 12x(0.0083333333)ln(36911.22/500) = 0\).0083333333x
Multiply both sides by 1000 and divide both sides by 0.0083333333 to get: x = 35.
Let x be the age of the person. When the person was born, their parents opened an investment account in their name and deposited $500 into the account.
Let A be the value of the investment account when the person is x years old.
The interest rate is 10% compounded monthly. Then, the monthly interest rate is
\(:r = (10/12)/100 = 0.0083333333\)
The account has earned interest for 12 * x months.
Hence, we have:
\(A = 500(1 + r)^(12x)\)
Now, we can solve for x.
A = 36911.22.
Hence:\(36911.22 = 500(1 + r)^(12x)\)
Take the natural logarithm of both sides to solve for x.
\(ln(36911.22/500) = 12x ln(1 + r)ln(36911.22/500) = 12x(0.0083333333)ln(36911.22/500) = 0.0083333333x\)
Multiply both sides by 1000 and divide both sides by 0.0083333333 to get: x = 35.

The graph of a sinusoidal function has a minimum point at (0, 3) and then intersects the midline at (π, 5). Show a graph of the function, then write the formula of the function where x is entered in radians.
y= sin(x) + 4 is the formula of the function where x is entered in radians.
To determine the equation of the sinusoidal function based on the given information, we can start by finding the amplitude, period, and phase shift.
Amplitude:
The distance between the midline and the minimum point is the amplitude.
The minimum point is (0, 3), and the midline is at y = 4. So the amplitude is |3 - 4| = 1.
The period is the distance it takes for the sinusoidal function to complete one full cycle.
Therefore, the period is 2π.
Phase shift is the horizontal shift of the graph.
The minimum point is at (0, 3), which means there is no phase shift.
y = Asin(Bx - C) + D
where:
A represents the amplitude,
B represents the frequency (2π divided by the period),
C represents the phase shift,
D represents the vertical shift (the midline value)
y = sin((2π/2π)x - 0) + 4
= sin(x) + 4
Hence, y= sin(x) + 4 is the formula of the function where x is entered in radians.

A drone is monitoring the atmospheric conditions above a farm field. The drone hovers 5 meters above the crop line. Suddenly, it rises to approximately 5.9 meters (which takes 1.9 seconds) to avoid colliding with the sprinkler system. Based on this information, which equations could model the height, y, of the drone as a function of time, x?
Answer:
The correct options are;
g(x) = -0.27·x² + x + 5
h(x) = 2·㏒(x + 1) + 5
Step-by-step explanation:
To answer the question, we substitute x = 1.9 seconds into the given options as follows;
1) For f(x) = √(1.6·x) + 5
When x = 1.9 seconds, we have;
y = f(1.9) = √(1.6×1.9) + 5 = 6.74 which is not equal to the given height of 5.9 meters
Therefore, f(x) = √(1.6·x) + 5 does not model the height of the drone y as a function of time, x
2) For g(x) = -0.27·x² + x + 5
When x = 1.9 seconds, we have;
y = g(1.9) = -0.27×1.9^2 + 1.9 + 5 = 5.93 meters, which is approximately 5.9 meters to one place of decimal
Therefore, the function, g(x) = -0.27·x² + x + 5, approximately models the height of the drone y as a function of time, x
3) For h(x) = 2·㏒(x + 1) + 5
When x = 1.9 seconds, we have;
y = h(1.9) = 2·log(1.9 + 1) + 5 = 5.92 meters,
The function, h(x) = 2·㏒(x + 1) + 5, approximately models the height of the drone y as a function of time, x
4) For j(x) = -∛(-1.4·x - 1) + 5
When x = 1.9 seconds, we have;
y = j(1.9) = -∛(-1.4×1.9 - 1) + 5 = 6.54 meters
The function j(x) = -∛(-1.4·x - 1) + 5 does not model the height of the drone y as a function of time, x
5) For k(x) = -1.2·x³ + 2.6·x² - 0.5·x + 5
When x = 1.9 seconds, we have;
y = k(1.9) = -1.2×1.9^3 + 2.6×1.9^2 - 0.5×1.9 + 5 = 5.21 meters
Therefore, the function, k(x) = -1.2·x³ + 2.6·x² - 0.5·x + 5, does not model the height of the drone y as a function of time, x

According to the lesson, describe in detail how you would use a centimeter ruler to measure a match stick?
To use a centimeter ruler to measure a matchstick, place the ruler parallel to the matchstick, aligning the zero mark with one end. Identify the nearest centimeter mark and estimate the millimeter measurement by looking at the divisions between centimeters and smaller increments for more precision.
To begin, ensure the centimeter ruler is in good condition and properly calibrated. Lay the matchstick on a flat surface, making sure it is straight. Position the ruler next to the matchstick, aligning the zero mark with one end while keeping it parallel to the matchstick. Observe the other end of the matchstick and identify the nearest centimeter mark on the ruler to the left of the end point. This represents the whole centimeter measurement. Next, look at the lines or ticks between the whole centimeter marks. Each centimeter is divided into 10 millimeter intervals. Estimate the length of the matchstick by identifying the millimeter line that aligns with the end of the matchstick. For more precise measurements, use the smaller divisions on the ruler. Each millimeter is further divided into smaller increments called tenths of a millimeter. Estimate the length by identifying the smallest increment that aligns with the end of the matchstick. Record the measurement by noting the number of centimeters, followed by the number of millimeters (and tenths of millimeters, if necessary). Handle the matchstick carefully to avoid any damage or inaccuracies in the measurement..

Write a quadratic equation and solve using any algebraic method.The area of a rectangular carpet is 216 square feet. The length of the carpet is 3 feet more than three times the width of the carpet. What are the dimensions (length and width) of the carpet?
explain why?
Answer: Let x be the width of the carpet in feet.
Then, the length of the carpet is 3 feet more than three times the width, which can be expressed as 3x + 3.
The area of a rectangle is given by the formula A = length × width. Therefore, the area of the carpet is:
A = (3x + 3) x = 3x² + 3x
We know that the area of the carpet is 216 square feet, so we can set up the equation:
3x² + 3x = 216
To solve for x, we can first divide both sides by 3:
x² + x = 72
Then, we can rearrange the equation to get it in standard quadratic form:
x² + x - 72 = 0
Now we can use the quadratic formula to solve for x:
x = (-b ± √(b² - 4ac)) / 2a
where a = 1, b = 1, and c = -72.
Plugging these values into the formula, we get:
x = (-1 ± √(1² - 4(1)(-72))) / 2(1)
x = (-1 ± √(1 + 288)) / 2
x = (-1 ± √289) / 2
x = (-1 ± 17) / 2
This gives us two possible values for x: x = -9 or x = 8.
Since the width of the carpet can't be negative, we reject the negative solution and conclude that the width of the carpet is 8 feet.
To find the length of the carpet, we can use the expression we found earlier: 3x + 3. Plugging in x = 8, we get:
length = 3(8) + 3 = 24 + 3 = 27
Therefore, the dimensions of the carpet are 8 feet by 27 feet.

Solve the following initial value problem. Y^(4)=−2sint+3cost with y′′′(0)=8,y′′(0)=−3,y′(0)=−2,y(0)=1
The solution to the initial value problem is:
y = (2sin(t) - 3cos(t)) / 81 + (8 2/3 / 6) t³ - (3 1/3 / 2) t² - 2t + 28/27.
Now, We can solve this initial value problem, for this we need to integrate the given differential equation four times, and use the given initial values to determine the constants of integration.
Starting with y⁴ = -2sin(t) + 3cos(t),
we can integrate four times to get:
y³ = (-2cos(t) - 3sin(t)) / 3 + C₁
y² = (-2sin(t) + 3cos(t)) / 9 + C₁t + C₂
y' = (-2cos(t) - 3sin(t)) / 27 + (C₁/2) t² + C₂t + C₃
y = (2sin(t) - 3cos(t)) / 81 + (C₁/6) t³ + (C₂/2) t² + C₃t + C₄
Using the given initial values, we can find the values of the constants of integration:
y'''(0) = 8 = -2/3 + C₁
C₁ = 8 2/3
y''(0) = -3 = 3/9 + C₁ × 0 + C₂
C₂ = -3 1/3
y'(0) = -2 = -2/27 + (C₁/2) 0² + C₂ 0 + C₃
C₃ = -2
y(0) = 1 = -3/81 + (C₁/6) 0³ + (C2/2) 0² + C₃ × 0 + C₄
C₄ = 1 + 3/81 = 28/27
So, the solution to the initial value problem is:
y = (2sin(t) - 3cos(t)) / 81 + (8 2/3 / 6) t³ - (3 1/3 / 2) t² - 2t + 28/27.

Which function best models the data?
y = 9,958(0.972)x
y = 0.972(9,958)x
y = 9,219x– 150
y = –150x + 9,219
Answer:
A.Step-by-step explanation:
The given table is
Days Bees
0 10,000
10 7,500
20 5,600
30 4,200
40 3,200
50 2,400
Where \(x\) represents days and \(y\) represents bees.
The exponential function that models this problem must be like
\(y=a(1-r)^{x}\), which represenst an exponential decary, because in this case, the number of bees decays.
We nned to use one points, to find the rate of decay. We know that \(a=10,000\), because it starts with 10,000 bees.
Let's use the points (10, 7500)
\(y=a(1-r)^{x}\\7500=10000(1-r)^{10}\)
Solving for \(r\), we have
\(\frac{7500}{10000}=(1-r)^{10} \\(1-r)^{10} =0.75\)
Using logarithms, we have
\(ln((1-r)^{10}) =ln(0.75)\\10 \times ln(1-r)=ln(0.75)\\ln(1-r)=\frac{ln(0.75)}{10} \approx -0.03\\e^{ln(1-r)}=e^{-0.03}\\1-r =e^{-0.03}\\r=-e^{-0.03}+1 \approx 1.97\)
Replacing all values in the model, we have
\(y=10000(1-1.97)^{x}\\y=10000(0.97)^{x}\)
Therefore, the right answer is the first choice, that's the best approximation to this situation.

The answer is 231 inches.
To understand how we arrive at this answer, let's break down the given measurement step by step. We have 6 yards, 3 feet, and 7 inches.
Starting with yards, we know that 1 yard is equal to 3 feet, so 6 yards would be equivalent to 6 * 3 = 18 feet. Adding the 3 feet given, we have a total of 18 + 3 = 21 feet.
Moving on to inches, we know that 1 foot is equal to 12 inches. So, the 21 feet we calculated earlier would be equal to 21 * 12 = 252 inches. Finally, adding the 7 inches given, we get a total of 252 + 7 = 259 inches.
