The Euler method with a step size of h = 0.5, the approximate numerical solution for the ODE is y(1.5) ≈ -1.1198 x 10^9.

To solve the ODE using the Euler method, we divide the interval into smaller steps and approximate the derivative with a difference quotient. Given that the step size is h = 0.5, we will perform three steps to obtain the numerical solution.

we calculate the initial condition: y(0) = -2.

1. we evaluate the derivative at t = 0 and y = -2:

y' = 3(0) - 10(-2)² = -40

Next, we update the values using the Euler method:

t₁ = 0 + 0.5 = 0.5

y₁ = -2 + (-40) * 0.5 = -22

2. y' = 3(0.5) - 10(-22)² = -14,860

Updating the values:

t₂ = 0.5 + 0.5 = 1

y₂ = -22 + (-14,860) * 0.5 = -7492

3. y' = 3(1) - 10(-7492)² ≈ -2.2395 x 10^9

Updating the values:

t₃ = 1 + 0.5 = 1.5

y₃ = -7492 + (-2.2395 x 10^9) * 0.5 = -1.1198 x 10^9

Therefore, after performing three steps of the Euler method with a step size of h = 0.5, the approximate numerical solution for the ODE is y(1.5) ≈ -1.1198 x 10^9.

The integral, ∫ [ (9ˣ - eˣ )/3ˣ ] dx evaluate value is 3ˣ/ ln(3) - eˣ/3ˣ(1 - ln 3). So, the correct answer is option (c).

Integration is defined as the process of finding the area of the region under the curve. This is done by drawing as many small rectangles covering up the area and summing up all their areas. If d/dx(F(x) = f(x), then ∫ f(x) dx = F(x) + C, where C is integration constant and indefinite integrals. We have an integral, say , I = ∫ [ (9ˣ - eˣ )/3ˣ ] dx

and we have to determine its value.

I = ∫ [ (9ˣ - eˣ )/3ˣ ] dx

=> I = ∫ [ (9ˣ/3ˣ - eˣ/3ˣ ] dx

=> I = ∫ [ (3²ˣ/3ˣ - eˣ/3ˣ ] dx

=> I = ∫ [ (3²ˣ/3ˣ - eˣ/3ˣ ] dx

=> I = ∫ [ (3ˣ - eˣ/3ˣ ] dx

=> I = ∫ 3ˣ dx - ∫ eˣ3⁻ˣ dx

=> I = 3ˣ/ ln(3) - eˣ/3ˣ(1 - ln 3) + C

( since, ∫aˣ dx = aˣ/ln a)

where C --> integration constant

The qualitative change in the shape of a graph is related to changes in the critical points, slope, and curvature of the function.

However, in general, the qualitative change in the shape of a graph occurs when there is a change in the number, location, or type of critical points (e.g., local maximum or minimum) of the function. Additionally, the behavior of the graph may change when there are changes in the slope or curvature of the function at certain points.

A qualitative change in the shape of a graph refers to a change that alters the overall appearance of the graph. This change occurs when there are significant modifications in the function's behavior that affect the number, location, or type of critical points of the function. For example, if the function has a single critical point at x=a, and as x increases, another critical point emerges at x=b, then there is a qualitative change in the shape of the graph.

Additionally, the behavior of the graph may change when there are alterations in the slope or curvature of the function at certain points. For instance, if the function has a point of inflection at x=c, and as x increases, the curvature changes significantly, then there is a qualitative change in the shape of the graph.

In summary, the qualitative change in the shape of a graph is related to changes in the critical points, slope, and curvature of the function.

Jennifer has 48 nickels, which means she has 144 quarters.

Let's call the number of nickels Jennifer has "n".

Since Jennifer has three more dimes than nickels, she has n + 3 dimes.

And since she has three times as many quarters as nickels, she has 3n quarters.

We can start by figuring out the total value of the nickels and dimes in terms of cents:

n * 5 cents + (n + 3) * 10 cents = 750 cents

Expanding the right side of the equation and solving for n:

5n + 10n + 30 cents = 750 cents

15n + 30 cents = 750 cents

15n = 720 cents

n = 48

So Jennifer has 48 nickels, which means she has 3 * 48 = 144 quarters.

The value of the given number 1 x 10¹⁰⁰ by applying the logarithms is equal to 100.

To find the number represented by 1 x 10¹⁰⁰ using logarithms, we can use the base-10 logarithm function.

The logarithm (base-10) of a number x is denoted as log(x) and represents the power to which 10 must be raised to get the number x.

Here, we have 1 x 10¹⁰⁰, and we want to find the value of x.

Using the logarithmic expression:

log(1 x 10¹⁰⁰) = log(1) + log(10¹⁰⁰)

The logarithm of 1 (log(1)) is equal to 0, so the expression simplifies to:

log(1 x 10¹⁰⁰) = 0 + log(10¹⁰⁰)

Now, using the property of logarithms, log(aᵇ) = b × log(a):

log(1 x 10¹⁰⁰) = 0 + 100 × log(10)

The logarithm of 10 (log(10)) is equal to 1, so:

log(1 x 10¹⁰⁰) = 0 + 100 × 1

Finally:

log(1 x 10¹⁰⁰) = 100

Therefore, the value of the number 1 x 10¹⁰⁰ using logarithms is 100.

∫cos(x)/8+cos(x)dx can be evaluated using substitution by letting w = sin(x) and the antiderivative is ∫ (1/8 + w)/sqrt(1-w^2) dw. ∫cos(x)/8+sin(x)dx cannot be evaluated using substitution.

To determine if substitution can be used to evaluate an integral, we can try to identify a pattern in the form of an integral. For example, we want to see if we can let w be equal to a part of the integrand that can simplify the integral and make it easier to solve. In the case of ∫cos(x)/8+cos(x)dx, we can let w = sin(x) which simplifies the integral to a standard form that can be solved using standard techniques.
