The object traveled 300 ft in 15 seconds.

The problem can be solved using precalculus. The distance traveled in 15 seconds can be calculated using the formula d = rt, where d is the distance traveled, r is the rate of speed, and t is the time. In this case, d = 20 ft/sec * 15 sec = 300 ft. Therefore, the object traveled 300 ft in 15 seconds. To calculate this using a graphical approach, we can plot the points (0,0) and (15,300) on a graph. The slope of the line connecting the two points is 20 ft/sec, which is the rate of speed of the object. This confirms that the object traveled 300 ft in 15 seconds.

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.

Now, 5x -2 > -22 and 6x-7 < 11

5x > -20 and 6x < 18

x > -4 and x<3.

x+5 >8 and 3+ 2x < -5

x >3 and x < -4.

so, the inequality is 5x -2 > -22 or 6x-7 < 11.

The measure of the frame in feet of the length and width are 3.667 feet and 2.125 feet respectively.

The unitary method is a method in which you find the value of a unit and then the value of a required number of units.

Given here: The measure of the frame is 8.5 inches and 11 inches

a) if the frame is 4 papers long then we  have the length of the frame as

11×4=44 inches (since he lays the paper along the edge of frame)

We know 1 inch= 0.0833 foot

Thus      44 inches= 3.66667 foot

b) Again if he lays the paper along the short edge than the width of the frame is 3×8.5=25.5 inches

∴25.5 inches= 2.125 feet

Therefore , the solution of the given problem of probability comes out to be probability that Both Rise - 0.06.

The possibilities of a given outcome in an event of sequence of events are referred to as probability.Consider the prices of two stocks as A & B based on the information provided. The following formula will be used to determine the likelihood that both stocks' prices will fall:

Here,

Decline Probability in A and B = PA(D) x PB (D)

Probability of Decline for A and B is -0.2 x 0.3.

Decline probabilities in A and B are 0.06

Now there will be a 100% chance of a price increase.

The likelihood of one rising is given by PA(U) x [PB(R) + PB(D)] + PB(U) x [PA(R) + PA(D)].

Chance of one rising is equal to 0.2 x (0.4 + 0). .3] +0.3 x (0.6+0.2

Chance that one increases is -0.38

For just one price remaining the same, now

One Unchanged Probability = PA (U) x [PB(R) + PB(D)]

[PA(R)+ P1 (D)] +PB(U)

Probability for a Single Unchanged Value is equal to 0.6 x [0.3 +0.3] +0.4 x [0.2+0 .2]

Probability for a Single Unchanged Value: 0.52

the likelihood that both prices will increase,

Both Rising Probability = PA(R)APB (R)

The solution to the initial value problem is given by:

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

The probability of a family having 0 teenagers with an Apple device can be calculated as (0.26)^0 * (0.74)^2 = 0.5356.

The probability of a family having 1 teenager with an Apple device can be calculated as 2 * (0.26) * (0.74)^1 * (0.74)^1 = 0.4428.

The probability of a family having 2 teenagers with an Apple device can be calculated as (0.26)^2 * (0.74)^0 = 0.0676.

Therefore, the probability of a family having 0, 1, or 2 teenagers with an Apple device can be calculated as 0.5356 + 0.4428 + 0.0676 = 1.0.

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

Marginal benefit = 15/1 = $15

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. Additionally, the limit of f(x) is not -2, meaning that the function does not approach this value as x gets larger.

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)

This is the second option

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.

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)

m = (- 7 - (-3)) / (4 - (-2))

m = - 4 / 6

m = - 2/3

Thus, The equation of line with slope - 2/3 is,
