The vehicle in motion produces 44000 joules of kinetic energy.

Kinetic energy is a type of power that a moving object or particle possesses.

An item accumulates kinetic energy doing work, which involves the transfer of energy, is done on it by exerting a net force.

Given, The formula for kinetic energy is, K = (1/2)mv².

The vehicle has a mass of 2200 kilograms and a velocity of 20 m/s.

So, Replacing the values in the formula will yield the result.

K = (1/2)mv².

The equivalent formula that does not involve integrals is A(x) = 2x - 2x^2 + 4x - 4.

The First Fundamental Theorem of Calculus states that if f(x) is a continuous function on the interval [a, b], then the function F(x) = integral^x_a f(t) dt is an antiderivative of f(x), meaning that its derivative is equal to f(x). Therefore, if we have the antiderivative of a function, we can use the derivative to find an equivalent formula without an integral.

In this case, the derivative of the antiderivative of f(t) = 4 - 2t is f(t) = 4 - 2t, which is the original function. So, the equivalent formula for A(x) is A(x) = 2x - 2x^2 + 4x - 4, which does not involve integrals.

⇒ y - y₁ = m (x - x₁)

Where, m = (y₂ - y₁) / (x₂ - x₁)

Given that;

Two points on the line are (-2, -3) and (4, -7).

Now,

Since, The equation of line passes through the points (-2, -3) and (4, -7).

So, We need to find the slope of the line.

Hence, Slope of the line is,

m = (y₂ - y₁) / (x₂ - x₁)

The missing marginal costs and benefits values are the following

Marginal benefit = $ 30

Marginal benefit = $25

See above we have a table with columns total cost, marginal cost , total benefits and marginal benefits. We have to determine the values in place of question mark (?) . Marginal benefit and marginal cost are two measures of how the price or value of a product changes.

Now, Marginal cost and benefits for row 2

change in total cost = 125- 100 = 25

change in units = 2 - 1 = 1

So, marginal cost = 25/1 = $25

Marginal benefit = change in total benefits/ change in units

= (150 - 120)/2-1 = 30/1 = $ 30

Change in total cost = 140 - 125 = 15

Change in units = 3 - 2 = 1

Change in total benefit = 175 - 150 = 25

So, marginal cost = 15/1 = $15

Marginal benefit = 25/1 = $25

Change in total cost = 160 - 140 = 20

Change in units = 4 - 3 = 1

Change in total benefit = 190 - 175= 15

So, marginal cost = 20/1 = $20

The inequality on the number line is 5x -2 > -22 or 6x-7 < 11.

Mathematical expressions with inequalities are those in which the two sides are not equal. Contrary to equations, we compare two values in inequality. Less than (or less than or equal to), greater than (or greater than or equal to), or not equal to signs are used in place of the equal sign.

Given:

The open circles on the number line shows that it does not include those value i.e., the values have less than and greater than.

So, from the number line the inequality is -4 < x < 3.

The limit of a function is the value that the function approaches as the argument approaches infinity. In the case of f(x), the limit is 2. This means that as x gets larger and larger, the value of f(x) gets closer and closer to 2. This implies that f(x) has a vertical asymptote at x = 2, meaning that the function approaches this value, but never reaches it. It does not have a horizontal asymptote at y = 2, meaning that the function does not approach this value as x gets larger.

Answer:

154.37500 US gallons

Answer:To determine if the function is a minimum or maximum value, we need to find its second derivative and see if it is positive or negative. If the second derivative is positive, the function is a minimum value, if it's negative, the function is a maximum value.

The second derivative of the given function is a constant (2), which means it is always positive. Therefore, the function g(x)=x^2+6x+8 is a minimum value.

The minimum value occurs at the vertex of the parabolic shape of the function, which can be found using the formula: x = -b / 2a, where a, b, and c are the coefficients of the function g(x) = ax^2 + bx + c. Plugging in the values, we get x = -6 / 2 * 1 = -3.

The minimum value of the function can be found by substituting the x value back into the function: g(-3) = (-3)^2 + 6(-3) + 8 = 9.

So the minimum value of the function g(x) = x^2 + 6x + 8 is 9, and it occurs at x = -3.

Step-by-step explanation:

Answer:

The function doesn't have maximum value, as it is always increasing, although it has minimum value which is -b/2a, in this case -3 is a minimum value

Based on the provide data, the predicted drag on the full-sized pole is 52.53 lb.

We have a graph between model velocity and model drag. Also we have two set of dimensions and we have to predict drag on the full-sized pole. Write the details as shown : Since, the working temperature is not given, assume T= 60°F. For model :

Length Lₘ = 2 ft

Diameter, dₘ = 1 in = 1/12 ft.

Velocity = Vₘ

Density in water, ρₘ =1.94 slugs/ft³

Dynamic Viscosity, μₘ= 2.373×10⁻⁵ lb-s/ft² ( water)

For prototype :

Length, Lₚ = 30 ft

Diameter, dₚ = 1.25 ft.

Velocity, Vₚ = 30 mph = 30 × 1.467 ft/s

= 44 ft/s

Density in air, ρₐ = 2.34×10⁻⁵ slugs/ft³

Dynamic Viscosity, μₐ= 3.75×10⁻⁶ lb-s/ft²

Determine the velocity of air using Reynolds number similarity as below :

ρₘ Vₘdₘ/μₘ = ρₐ Vₚ dₚ/ μₐ

=> Vₘ = (ρₐ/ρₘ)(dₚ/dₘ)(μₘ/μₐ)Vₚ

=> Vₘ = ( 2.34×10⁻⁵ /1.94)(1.25 /1/12 )(2.373×10⁻⁵/3.75×10⁻⁷ )44

Vₘ = 50.37 ft/s

From the graph, the value of drag corresponding to Vₘ = 50.37 ft/s is 253.7 lb. Determine the drag on the full-sized pole: Fₚ/dₚ² Vp²ρₐ = Fₘ(Vₘ²dₘ²ρₘ)

=> Fₚ = Fₘ( dₚ/dₘ)²(Vₚ/Vₘ)²(ρₐ/ρₘ)

=> Fₚ = 253.7 lb ( 1.25 ft/1/12ft )²( 44 ft/s/50.37 ft/s)²( 2.34×10⁻⁵slugs/ft³/1.94 slugs/ft³)
