Alex purchases 13 cans of tomatoes and the remaining 19 cans are corn.

Let's assume that Alex buys 'x' cans of tomatoes. Since he buys a total of 32 cans of vegetables, he must buy the remaining (32 - x) cans of corn. According to the given information, each can of tomatoes costs 80 cents, and each can of corn costs 40 cents.

The cost of x cans of tomatoes is calculated as 80x cents, and the cost of (32 - x) cans of corn is calculated as 40(32 - x) cents. Adding these two costs together, we get the total cost of $18, which is equivalent to 1800 cents.

So, the equation can be formed as follows:

80x + 40(32 - x) = 1800

Now, let's solve this equation:

80x + 1280 - 40x = 1800

40x + 1280 = 1800

40x = 520

x = 520/40

x = 13

Therefore, Alex buys 13 cans of tomatoes.

The cost function is given by C(x) = (-x³/360000) + 33.33.  The fixed costs are $ 33.33.

Given that the marginal average cost of producing x digital sports watches is given by the function C(X), where Cˉ(x) is the average cost in dollars and

 Cˉ′(x)=-x²/1200;

Cˉ(100)=25.

To find the average cost function, integrate the Cˉ′(x) and add an arbitrary constant c, as follows:

Cˉ′(x) = dC/dx

⇒ dC/dx = -x²/1200.

Integrating both sides w.r.t x, we get

C = ∫dC/dx dx

⇒ C = ∫(-x²/1200) dx.

Integrate the above integral using power rule, we get

C(x) = (-x³/360000) + c.

Now, substituting

Cˉ(100)=25, we have

25 = (-100³/360000) + c

⇒ c = 25 + (100³/360000)

⇒ c = 33.33

Therefore, the average cost function is given by

C(x) = (-x³/360000) + 33.33.

Now, to find the cost function, take the integral of the average cost function from 0 to x, as follows:

C(x) = ∫C'(x) dx.

Substituting the value of C'(x) in the above integral, we get:

C(x) = ∫(-x²/1200) dx.

Using power rule, the above integral can be integrated as

C(x) = (-x³/360000) + c.

Substituting c = 33.33, we get:

C(x) = (-x³/360000) + 33.33

Lance should purchase 3/2 hamburgers and 1/2 orders of fries to maximize their satisfaction.

We are given that:

Lance has $5 to spend on hamburgers ($3 each) and french fries ($1 per order).Lance's satisfaction from eating a hamburgers and y orders of french fries is measured by a function

S(x, y) = √(xy).

Use the method of Lagrange Multipliers to find how much of each type of food should Lance purchase to maximize their satisfaction. (Assume that the restaurant is very accommodating and allow fractional amounts of food to be purchased.)

We are supposed to maximize the satisfaction of Lance i.e., we need to maximize the function given by

S(x, y) = √(xy).

Let x and y be the number of hamburgers and orders of fries purchased by Lance, respectively.

Let P be the amount Lance spends on the food.

P = 3x + y -----------(1)

Since Lance has only $5 to spend, therefore

P = 3x + y = 5. --------- (2)

Therefore, we have to maximize the function S(x, y) = √(xy) subject to the constraint

3x + y = 5

Using the method of Lagrange Multipliers, we have:

L(x, y, λ) = √(xy) + λ (3x + y - 5)

For stationary points, we must have:

Lx = λ 3/2√(y/x)

= λ 3 ... (3)

Ly = λ 1/2√(x/y)

= λ ... (4)

Lλ = 3x + y - 5

Squaring equations (3) and (4), we have:

3y = x ... (6)

Again, substituting 3y = x in equation (5), we have:

9y + y - 5 = 0

=> y = 5/10

We use the concept of normalization. The first step is to calculate the width and height of both the window and the viewport. Then, we determine the normalization factors for both the X and Y coordinates.

To convert the window coordinates to viewport coordinates, we need to normalize the values. First, we calculate the width and height of both the window and the viewport. The width of the window [tex](\(W_w\))[/tex] is given by [tex]\(X_{wmax} - X_{wmin} = 80 - 20 = 60\)[/tex], and the height of the window [tex](\(H_w\))[/tex] is given by [tex]\(Y_{wmax} - Y_{wmin} = 80 - 40 = 40\)[/tex].

Similarly, we calculate the width and height of the viewport. Let's assume the width of the viewport is \(W_v\) and the height is \(H_v\). In this case, the given values for the viewport are not provided. Hence, we cannot determine the exact values for the width and height of the viewport.

To find the slope of the curve at the indicated point, given

`y = x^2 + 5x +4, x = -1`,

we will use the first principle of differentiation.

The slope of the curve can be obtained by finding the derivative of the given equation.

First, we differentiate the function with respect to `x` using the first principle of differentiation.

This is given as:

`(dy)/(dx) = [f(x+h) - f(x)]/h`

Let

`f(x) = x^2 + 5x + 4`.

Then

`f(x + h) = (x + h)^2 + 5(x + h) + 4

= x^2 + 2hx + h^2 + 5x + 5h + 4`

Substituting the values in the formula:

`(dy)/(dx) = lim (h→0) [f(x+h) - f(x)]/h

= lim (h→0) [(x^2 + 2hx + h^2 + 5x + 5h + 4) - (x^2 + 5x + 4)]/h` `

= lim (h→0) [2hx + h^2 + 5h]/h

= lim (h→0) [2x + h + 5]`

Thus, the slope of the curve at the given point is:

`m = (dy)/(dx)

= 2x + 5

= 2(-1) + 5

= 3`.

These equations represent the parametric equations for the x and y coordinates of the curve, respectively. The parameter "u" represents the parameterization of the curve, and the coefficients c0, c1, c2, and c3 are the control points that determine the shape of the curve.

By varying the values of the control points c0, c1, c2, and c3, the curve can be manipulated to create different shapes. The quadratic term u^2 contributes to the curvature of the curve, while the linear terms c1u and c2 affect the slope and position of the curve. The coefficient c3 determines the height or vertical position of the curve.

To create a curve using this quadratic parametric approach with three interpolated control points, specific values need to be assigned to the coefficients c0, c1, c2, and c3.

Relative humidity tends to be highest during the early morning hours, shortly before sunrise.

To determine the Wet-Bulb Temperature (WBT) and Wet-Bulb Depression (WBD), we need the dry-bulb temperature (DBT) and relative humidity (RH) values.

The Wet-Bulb Temperature (WBT) is the lowest temperature that can be achieved by evaporating water into the air at constant pressure, while the Wet-Bulb Depression (WBD) is the difference between the dry-bulb temperature (DBT) and the wet-bulb temperature (WBT). These values are useful in determining the potential for evaporative cooling and assessing heat stress conditions.

Day 1: Air Temperature= 86°F and RH= 60%

To calculate the WBT and WBD for Day 1, we would need additional information such as the barometric pressure or the dew point temperature. Without these values, we cannot determine the specific WBT or WBD for this day.

Day 2: Air Temperature= 41°F and RH= 90%

Similarly, without the necessary additional information, we cannot calculate the WBT or WBD for Day 2.

Regarding your question about the point during the day with the lowest and highest outside relative humidity values, it is generally observed that the relative humidity tends to be highest during the early morning hours, shortly before sunrise. This is because the air temperature often reaches its lowest point overnight, and as the air cools, its capacity to hold moisture decreases, leading to higher relative humidity values.

Conversely, the outside relative humidity tends to be lowest during the late afternoon, typically around the hottest time of the day. As the air temperature rises, its capacity to hold moisture increases, resulting in lower relative humidity values.

It's important to note that these patterns can vary depending on the local climate, weather conditions, and geographical location. Other factors such as wind patterns and nearby bodies of water can also influence relative humidity throughout the day.

The problem of traveling from the west-most point \( s \) to the east-most point \( t \) of a 1-dimensional segment with \( n \) teleporters can be approached using dynamic programming. Let's consider the subproblem of reaching each point \( x \) on the segment and compute the minimum cost to reach \( x \).

Let's define an array \( dp \) of size \( n+2 \), where \( dp[x] \) represents the minimum cost to reach point \( x \). We initialize all elements of \( dp \) with a large value (infinity) except for \( dp[s] \) which is set to 0, as the cost to reach the starting point is 0.

We can then iterate through each point \( x \) on the segment and update \( dp[x] \) by considering all possible teleporters. For each teleporter at position \( p \), we can teleport from \( p \) to \( x \) with a cost of \( c \). We update \( dp[x] \) by taking the minimum of the current value of \( dp[x] \) and \( dp[p] + c \).

Finally, the minimum cost to reach the east-most point \( t \) will be stored in \( dp[t] \).

Polynomial is a mathematical approximation of the data, allowing researchers to estimate values between the given data points. Interpolating polynomials are commonly used when the exact function or relationship between variables is unknown but can be approximated by a polynomial curve.

When dealing with experimental data represented by a set of points in the plane, an interpolating polynomial is a valuable tool for analyzing and estimating values within the data range. The goal is to find a polynomial equation that passes through each point, providing a mathematical representation of the observed data.

Interpolating polynomials are particularly useful when the exact functional relationship between variables is unknown or complex, but it is still necessary to estimate values between the given data points. By fitting a polynomial curve to the data, scientists and researchers can make predictions, calculate derivatives or integrals, and perform other mathematical operations with ease.

Various methods can be employed to construct interpolating polynomials, such as Newton's divided differences, Lagrange polynomials, or using the Vandermonde matrix. The choice of method depends on the specific requirements of the data set and the desired accuracy of the approximation.

It is important to note that while interpolating polynomials provide a convenient and often accurate representation of experimental data, they may not capture all the underlying intricacies or provide meaningful extrapolation beyond the given data range. Additionally, the degree of the polynomial used should be carefully considered to avoid overfitting or excessive complexity.

The dimensions of the box are approximately: side length = 9.36 inches, and height = 14.62 inches.

Let's denote the side length of the square base as s, and the height of the box as h.

We are given the volume of the box as 150 cubic inches, so we can write the equation:

Volume = s^2 * h = 150.

The surface area of the box is given as 145 square inches, which consists of the base area (s^2) and four equal side areas (4s * h):

Surface Area = s^2 + 4s * h = 145.

We also know that the height of the box must be larger than 8 inches, so we have the condition:

h > 8.

Now, let's solve these equations simultaneously. We can rearrange the second equation to express h in terms of s:

h = (145 - s^2) / (4s).

Substituting this expression for h into the volume equation, we have:

s^2 * [(145 - s^2) / (4s)] = 150.

Simplifying this equation, we get:

s^3 - 600s + 580 = 0.

This is a cubic equation, and solving it can be quite complex. We can use numerical methods or calculators to approximate the solution. After solving, we find that the side length of the square base is approximately 9.36 inches and the height of the box is approximately 14.62 inches.

The value of "ω" for which the function returns a 3 dB response in the expression 20log(|1 + jwt|) is approximately 15245.67.

In the given function, 20log(|1 + jwt|), the term inside the logarithm represents a complex number with a real part of 1 and an imaginary part of jwt. To determine the value of "ω" for a 3 dB response, we need to find the frequency at which the magnitude of the complex number is 3 dB lower than its maximum value.

In decibels, a reduction of 3 dB corresponds to a power ratio of 0.5 (or an amplitude ratio of √0.5). Converting this to a magnitude ratio, we have 0.5 = |1 + jwt|/|1 + jwt|max.

Squaring both sides of the equation, we get 0.25 = |1 + jwt|²/|1 + jwt|max².

Expanding the square and rearranging the terms, we have 0.25 = (1 + jwt)(1 + j(-wt))/|1 + jwt|max².

Simplifying further, we get 0.25 = (1 - wt²)/|1 + jwt|max².

Since the real part of the complex number is 1, we have |1 + jwt|max = 1.

Substituting T = 1.3606746 x [tex]10^(^-^4^)[/tex] for wt, we get [tex]0.25 = (1 - w^2T^2)/1.[/tex]

Rearranging the equation, we have[tex]1 - w^2T^2 = 0.25.[/tex]

Solving for w, we find [tex]w^2T^2 = 0.75.[/tex]

Taking the square root of both sides, we obtain wT = √0.75.

Dividing both sides by T, we get w = √0.75/T.

Substituting the given value of T = 1.3606746 x [tex]10^(^-^4^)[/tex], we have w ≈ √0.75/(1.3606746 x [tex]10^(^-^4^)[/tex]).

Evaluating the expression, we find w ≈ 15245.67.

Therefore, the value of "ω" for which the function returns a 3 dB response is approximately 15245.67.

The sum of the infinite terms for the given geometric sequence is (B) -32.

To find the sum of an infinite geometric series, we need to determine if the series converges or diverges. For a geometric series to converge, the absolute value of the common ratio (r) must be less than 1.

In this case, the common ratio (r) can be found by dividing any term by its preceding term:

r = 24 / (-48) = -1/2

Since the absolute value of -1/2 is less than 1 (|r| < 1), the series converges.

The sum of an infinite geometric series can be calculated using the formula:

S = a / (1 - r)

Where "a" is the first term of the series and "r" is the common ratio.

Plugging in the values, we have:

S = (-48) / (1 - (-1/2))

 = (-48) / (1 + 1/2)

 = (-48) / (3/2)

 = (-48) * (2/3)

 = -32

Therefore, the sum of the infinite terms for the given geometric sequence is (B) -32.

a) To find the inverse Fourier transform of X(w) = 2δ(w-1) + 3δ(w) + 2δ(w+1), where δ(w) represents the Dirac delta function, we can apply the inverse Fourier transform formula. Using the properties of the Dirac delta function,

we know that its inverse Fourier transform is a constant function. Therefore, the inverse Fourier transform of X(w) is given by x(t) = 2e^(jωt)e^(-jω) + 3 + 2e^(jωt)e^(jω), which simplifies to x(t) = 2e^(-jωt) + 3 + 2e^(jωt).

b) For Y(w) = 7cos(3w), we can use the inverse Fourier transform properties and the Fourier transform of the cosine function. The Fourier transform of cos(at) is given by ½[δ(w - a) + δ(w + a)]. In this case, the inverse Fourier transform of Y(w) is y(t) = 7/2[δ(w - 3) + δ(w + 3)].

c) For Y(w) = 20nTδ(w - 3)/(5w - 5), where nT is the unit step function, we can use the inverse Fourier transform properties and the Fourier transform of the unit step function. The Fourier transform of nT is given by 1/(jw) + πδ(w). Substituting this into Y(w), we have Y(w) = 20[1/(jw) + πδ(w)]δ(w - 3)/(5w - 5). Simplifying this expression, the inverse Fourier transform of Y(w) is y(t) = 20[1 + πnT(t - 3)].

(a) To express [tex]\(\frac{x-2}{(x-1)^2(x+1)}\)[/tex] in partial fractions, we start by factoring the denominator:

[tex]\((x-1)^2(x+1) = (x^2 - 2x + 1)(x+1) = x^3 - x^2 - 2x^2 + 2x + x - 1 = x^3 - 3x^2 + 3x - 1\).[/tex]

Now, we can express the fraction as:

[tex]\[\frac{x-2}{(x-1)^2(x+1)} = \frac{A}{x-1} + \frac{B}{(x-1)^2} + \frac{C}{x+1}\].[/tex]

To determine the values of A, B, and C, we need to find a common denominator on the right side:

[tex]\[\frac{A(x-1)(x+1) + B(x+1) + C(x-1)^2}{(x-1)^2(x+1)} = \frac{(A+B)x^2 + (A-C)x + (-A+B-C)}{(x-1)^2(x+1)}\].[/tex]

Equating the numerators, we get the following system of equations:

[tex]\(A+B = 0\),\\\(A-C = -2\),\\\(-A+B-C = 1\).[/tex]

Solving this system of equations, we find [tex]\(A = -1\), \(B = 1\), and \(C = -1\)[/tex].

Therefore, the expression [tex]\(\frac{x-2}{(x-1)^2(x+1)}\)[/tex] can be written as [tex]\[\frac{-1}{x-1} + \frac{1}{(x-1)^2} - \frac{1}{x+1}\].[/tex]

(b) The exponential definition of [tex]\(\cos h x\)[/tex] is [tex]\(\cos h x = \frac{e^x + e^{-x}}{2}\).[/tex]

To find the solutions of [tex]\(\cos h x = 5\)[/tex], we substitute this expression into the equation:

[tex]\[\frac{e^x + e^{-x}}{2} = 5\].[/tex]

Multiplying both sides by 2, we have:

[tex]\[e^x + e^{-x} = 10\].[/tex]

Multiplying through by [tex]\(e^x\)[/tex], we get a quadratic equation:

[tex]\[e^{2x} - 10e^x + 1 = 0\].[/tex]

We can solve this quadratic equation using the quadratic formula:

[tex]\[e^x = \frac{10 \pm \sqrt{10^2 - 4(1)(1)}}{2} = \frac{10 \pm \sqrt{96}}{2} = \frac{10 \pm 4\sqrt{6}}{2}\].[/tex]

Simplifying further, we have:

[tex]\[e^x = 5 \pm 2\sqrt{6}\].[/tex]

Taking the natural logarithm of both sides, we obtain:

[tex]\[x = \ln(5 \pm 2\sqrt{6})\].[/tex]

Therefore, the two solutions of [tex]\(\cos h x = 5\)[/tex] are [tex]\(x = \ln(5 + 2\sqrt{6})\) and \(x = \ln(5 - 2\sqrt{6})\).[/tex]

To find the dimensions of a similar triangular prism, we need to consider the proportional relationship between the corresponding sides of the two prisms.

A similar triangular prism maintains the same shape as the original prism but can have different dimensions. The key is that the ratios between corresponding sides remain constant.

Let's assume the dimensions of the similar triangular prism are represented by the variables "x," "y," and "z" for length, width, and height, respectively.

To determine the dimensions, we can set up the following ratios based on the given prism:

Length ratio: x/16 = y/10 = z/6

Width ratio: x/16 = y/10 = z/6

Height ratio: x/16 = y/10 = z/6

Now, we can solve for "x," "y," and "z" by cross-multiplying and simplifying:

x/16 = y/10 = z/6

Simplifying the ratios, we have:

10x = 16y

6x = 16z

To find a set of dimensions that satisfies these equations, we can choose any values for "x," "y," and "z" that maintain this ratio relationship. For example, we can let x = 8, y = 5, and z = 3, which satisfies the equations.

Therefore, a similar triangular prism would have dimensions of 8 cm for length, 5 cm for width, and 3 cm for height.

There cannot exist two distinct input values that map to the same output value.

Therefore, the function f(x) is one-to-one.

Given a function f:[0, [infinity]) → R defined as f(x) = -1/2 x + 4.i) State the domain and the range of the function:

The domain of a function is the set of all possible input values, and the range is the set of all possible output values.

Here, we can see that the function is defined from 0 to infinity, which means the domain is [0, infinity)

.Now, to determine the range, we need to consider the output values that can be obtained from the function.

The function is a linear function with a negative slope, which means it decreases as x increases.

Also, we can see that the y-intercept is 4. So, the range of the function is (-infinity, 4].

ii) Determine whether f(x) is one-to one function:

To determine whether a function is one-to-one, we need to check whether each input value maps to a unique output value or not. In other words, if x1 ≠ x2, then f(x1) ≠ f(x2).

Let's assume that there exist two input values x1 and x2 such that x1 ≠ x2 and f(x1) = f(x2).

Then, we have:-

1/2 x1 + 4 = -1/2 x2 + 4

Multiplying both sides by -2, we get:

x2 - x1 = 0x2 = x1

This contradicts our assumption that x1 ≠ x2.

Hence, there cannot exist two distinct input values that map to the same output value.

Therefore, the function f(x) is one-to-one.

The equation of the line that passes through the point (-1/2, 1) and is perpendicular to the line 2x + 5y = 3 is y = (5/2)x + 9/4.

To find the equation of a line that passes through the point (-1/2, 1) and is perpendicular to the line 2x + 5y = 3, we first need to determine the slope of the given line.

The equation of the given line, 2x + 5y = 3, can be rewritten in slope-intercept form (y = mx + b) by isolating y:

5y = -2x + 3

Dividing both sides of the equation by 5, we have:

y = (-2/5)x + 3/5

Comparing this equation to the slope-intercept form (y = mx + b), we can see that the slope of the given line is -2/5.

To find the slope of the line perpendicular to the given line, we can use the property that the product of the slopes of two perpendicular lines is -1. Therefore, the slope of the perpendicular line is the negative reciprocal of -2/5, which is 5/2.

Now that we have the slope (m = 5/2) and a point (-1/2, 1) on the line, we can use the point-slope form of the equation of a line:

y - y1 = m(x - x1)

Substituting the values, we have:

y - 1 = (5/2)(x - (-1/2))

Simplifying, we get:

y - 1 = (5/2)(x + 1/2)

Next, distribute the (5/2) to both terms inside the parentheses:

y - 1 = (5/2)x + 5/4

Finally, bring the constant term to the other side of the equation:

y = (5/2)x + 5/4 + 1

Simplifying further, we have:

y = (5/2)x + 5/4 + 4/4

y = (5/2)x + 9/4

The AM signal plot on the given graph paper will show the message signal with a Root Mean Square (RMS) of 2√2, along with the carrier signal and the modulated signal, denoted by V and Vm respectively. The modulation index is 40%.

Step 1: Determine the peak voltage of the message signal.

Given that the message signal's RMS voltage is 2√2, we can find the peak voltage (Vm) using the formula:

Vm = RMS × √2

Vm = 2√2 × √2

Vm = 2 × 2

Vm = 4

Step 2: Calculate the modulation index (m).

The modulation index (m) is given as 40%, which can be written as 0.4.

m = 0.4

Step 3: Determine the amplitude of the carrier signal.

The carrier signal's amplitude (V) can be calculated by dividing the peak voltage of the modulated signal by the modulation index:

V = Vm / m

V = 4 / 0.4

V = 10

The AM signal can be plotted on the graph paper with appropriate scaling. The message Root Mean Square (RMS) is 2√2, and the modulation index is 40%.

To plot the AM signal, we first need to understand the concept of modulation index. Modulation index (m) is a measure of the extent of modulation imposed on the carrier signal by the message signal. In this case, the modulation index is 40%, which means that the amplitude of the carrier signal varies by 40% of the peak amplitude due to modulation.

The message Root Mean Square (RMS) value represents the amplitude of the message signal. Given that the RMS is 2√2, we can calculate the peak voltage (Vm) of the message signal using the formula Vm = √2 * RMS. Therefore, Vm = √2 * 2√2 = 4V.

Next, we need to determine the carrier signal amplitude (V). The carrier signal remains constant in amplitude but varies in frequency. Since the modulation index is 40%, the carrier signal will have a peak-to-peak variation of 40% * Vm = 0.4 * 4V = 1.6V.

Now, we can plot the AM signal on the graph paper. The x-axis represents time, and the y-axis represents voltage. The carrier signal will have a constant amplitude of V, while the message signal will vary between -Vm and +Vm.

On the plot, we can mark the values of Vm and V to indicate the amplitudes of the message and carrier signals, respectively. Additionally, we can mark the related voltages, such as -0.4Vm, 0.4Vm, -Vm, Vm, etc., to represent different points on the AM signal.

The approximate value of y(3) using Heun's method with a step size of h = 1.5 is 5.72578125.

The approximate value of y(3) using Ralston's method with a step size of h = 1.5 is 4.4223046875.

Heun's Method:

Heun's method, also known as the Improved Euler method, is a numerical approximation technique for solving ordinary differential equations.

Given the differential equation: [tex]\(2y + 1.1\frac{dy}{dx} = 5x\)[/tex] with the initial condition [tex](y(0) = 2.1\)[/tex] , we can rewrite it as:

[tex]\(\frac{dy}{dx} = \frac{5x - 2y}{1.1}\)[/tex]

Step 1:

x0 = 0

y0 = 2.1

Step 2:

x1 = x0 + h = 0 + 1.5 = 1.5

k1 = (5x0 - 1.1y0) / 2 = (5 * 0 - 1.1 * 2.1) / 2 = -1.155

y1 predicted = y0 + h  k1 = 2.1 + 1.5  (-1.155) = 0.8175

Step 3:

k2 = (5x1 - 1.1 y1) / 2 = (5 x 1.5 - 1.1 x 0.8175) / 2 = 2.15375

y1  = y0 + h x (k1 + k2) / 2 = 2.1 + 1.5 x ( (-1.155) + 2.15375 ) / 2 = 1.538125

Now, we repeat the above steps until we reach x = 3.

Step 4:

x2 = x1 + h = 1.5 + 1.5 = 3

k1 = (5x1 - 1.1 y1 ) / 2 = (5 x 1.5 - 1.1 x 1.538125) / 2 = 1.50578125

y2 predicted = y1 + h x k1 = 1.538125 + 1.5 x 1.50578125 = 4.0703125

Step 5:

k2 = (5x2 - 1.1 y2 predicted) / 2

= (5 x 3 - 1.1 x 4.0703125) / 2

= 4.3592578125

y2 corrected = y1 corrected + h   (k1 + k2) / 2 = 1.538125 + 1.5 x (1.50578125 + 4.3592578125) / 2 = 5.72578125

The approximate value of y(3) using Heun's method with a step size of h = 1.5 is 5.72578125.

dy/dx = (5x - 1.8y) / 2

Now,

Step 1:

x0 = 0

y0 = 3.5

Step 2:

x1 = x0 + h = 0 + 1.5 = 1.5

k1 = (5x0 - 1.8y0) / 2 = (5 x 0 - 1.8 x 3.5) / 2 = -3.15

y1 predicted = y0 + h x k1 = 3.5 + 1.5 x (-3.15) = -2.025

Step 3:

k2 = (5x1 - 1.8 y1 predicted) / 2 = (5 x 1.5 - 1.8 (-2.025)) / 2 = 3.41775

y1 corrected = y0 + (h / 3)  (k1 + 2 x k2) = 3.5 + (1.5 / 3) (-3.15 + 2 x 3.41775) = 1.901625

Now, we repeat the above steps until we reach x = 3.
