what are the domain and range of the following quadratic

Answer:

The room can accommodate 4.5 students.

Step-by-step explanation:

12 square feet = 144 square inches of floor space

24 x 27 = 648 square feet of floor space

648 / 144 = 4.5

The room can accommodate 4.5 students.

The area inside the loop of the limacon given by the polar equation r = 7 - 14sin(θ) is 294π square units.

To find the area inside the loop of the limacon given by the polar equation r = 7 - 14sin(θ), we need to evaluate the integral for half of the area and then double the result.

The curve of the limacon has a loop when 0 ≤ θ ≤ π, so we integrate from 0 to π. The area can be calculated as follows:

A = 2 ∫₀^π 1/2 r² dθ

Using the equation for r given, we can substitute and simplify:

A = 2 ∫₀^π 1/2 (7 - 14sin(θ))² dθ

A = 2 ∫₀^π 1/2 (49 - 196sin(θ) + 196sin²(θ)) dθ

A = ∫₀^π (98 - 392sin(θ) + 392sin²(θ)) dθ

Using the trigonometric identity 1 - cos(2θ) = 2sin²(θ), we can simplify further:

A = ∫₀^π (98 - 392sin(θ) + 196 - 196cos(2θ)) dθ

A = ∫₀^π (294 - 392sin(θ) - 196cos(2θ)) dθ

Integrating with respect to θ:

A = [294θ + 392cos(θ)sin(θ) + 98sin(θ)]₀^π

Evaluating at the limits of integration, we get:

A = [294π + 0 + 0] - [0 + 392cos(0)sin(0) + 98sin(0)]

A = 294π - 0 - 0 = 294π

Therefore, the area inside the loop of the limacon r = 7 - 14sin(θ) is 294π square units.

The cost of 1 kilogram of pears is $5.70.

The cost of 1 kilogram of pears can be found by using the given information and setting up an equation. First, let's repeat the question: "1 kilogram of pears cost as much as 1.5 kilograms of apples. Alex paid $34.20 for 4 kilograms of pears and 3 kilograms for apples. How much did 1 kilogram of pears cost?"

Let's assign variables to the unknowns:

- P = cost of 1 kilogram of pears

- A = cost of 1 kilogram of apples

From the question, we know that:

- 1P = 1.5A - 4P + 3A = 34.20

Now, we can use substitution to solve for P.

1. Substitute 1.5A for P in the second equation: 4(1.5A) + 3A = 34.20

2. Simplify: 6A + 3A = 34.20

3. Combine like terms: 9A = 34.20

4. Solve for A: A = 34.20/9 A = 3.8

5. Substitute 3.8 for A in the first equation: 1P = 1.5(3.8)

3                                               6,755

Let the formula for an exponential function would be as

⇒ v(x) = abˣ

Substitute the value of x = 0 and v(x) = 11,000 in the above equation,

⇒ 11,000 = ab⁰

⇒ a = 11,000

Now, substitute the value of x = 1 and v(x) = 9,350, and we get

⇒ 9,350 = ab¹

⇒ 9,350 = (11,000)b

⇒ b = 9,350/11,000

⇒ b = 0.85

Substitute the value of a = 11,000 and b = 0.85 in v(x) = abˣ,

⇒ y = 11,000 (0.85)ˣ

Thus, the exponential function is y = 11,000 (0.85)ˣ.

The conversion from ml to teaspoon is 1 ml = 0.202884 tsp. This means that 30 ml is equal to 6.08652 teaspoons.

This conversion can be calculated by multiplying the volume in ml with 0.202884. The formula for this conversion is Volume (tsp) = Volume (ml) x 0.202884. For example, if the volume is 30 ml, the calculation would be 30 ml x 0.202884 = 6.08652 tsp. This means that 30 ml is equal to 6.08652 teaspoons.To convert between other units of volume, such as liters and gallons, the conversion factor must be changed. For example, to convert from liters to teaspoons, the conversion factor would be 0.0147867. To convert from gallons to teaspoons, the conversion factor would be 76.7526. It is important to remember that the conversion factor must be changed depending on the units being converted.In conclusion, 30 ml is equal to 6.08652 teaspoons.

This statement is False as the probability of intersection of two events is always less than the probability of union.

This assertion is untrue. Contrary to popular belief, the likelihood of two occurrences coming together is always higher than or on pair with the likelihood of them colliding.

The chance of two events A and B occurring together can be calculated using the following formula to see why:

According to this equation, the probability of A and B joining together is equal to the total of their individual probabilities less the likelihood of their colliding.

When we rewrite this calculation and focus only on the likelihood of the intersection, we obtain:

Now it is clear that the probability of the intersection is determined by subtracting the probability of their union from the sum of the probabilities of A and B.

P(A) and P(B) are both less than or equal to P(A B), since probabilities can never be negative. P(A + B) is therefore less than or equal to twice P(A + B) when they are added together. Thus, it follows:

This indicates that, contrary to what the original statement implied, the probability of the intersection is not greater than or equal to the probability of the union.

Graphically, the feasible solutions represent the points in the x-y plane that are inside the region defined by the three lines, and they can be found by plotting the three lines and shading the region below each line. The feasible solutions are the points in the shaded region that are common to all three.

Let x be the number of cubic yards of mix A used, and y be the number of cubic yards of mix B used. Then the total amount of phosphoric acid, nitrogen, and potash can be expressed as follows:

Phosphoric acid: 20x + 10y >= 460

Nitrogen: 30x + 30y >= 960

Potash: 5x + 10y >= 220

These inequalities represent the minimum monthly requirements for phosphoric acid, nitrogen, and potash. To find the feasible solutions, we need to find the values of x and y that satisfy all three inequalities simultaneously. This can be done graphically by plotting the three inequalities on the same coordinate plane and finding the region that is common to all three.

To plot the inequalities, we can choose convenient values for x and y, substitute them into the inequalities, and find the corresponding values of the right-hand side. For example, if we choose x = 0 and y = 0, then we have:

Phosphoric acid: 20 * 0 + 10 * 0 >= 460

Nitrogen: 30 * 0 + 30 * 0 >= 960

Potash: 5 * 0 + 10 * 0 >= 220

which gives us:

Phosphoric acid: 0 >= 460

Nitrogen: 0 >= 960

Potash: 0 >= 220

These values are all negative, which means that x = 0 and y = 0 do not satisfy the inequalities.

Next, we can choose x = 1 and y = 0, then we have:

Phosphoric acid: 20 * 1 + 10 * 0 >= 460

Nitrogen: 30 * 1 + 30 * 0 >= 960

Potash: 5 * 1 + 10 * 0 >= 220

which gives us:

Phosphoric acid: 20 >= 460

Nitrogen: 30 >= 960

Potash: 5 >= 220

These values are also negative, which means that x = 1 and y = 0 do not satisfy the inequalities either.

We can continue this process until we find values of x and y that satisfy all three inequalities. The feasible solutions are the values of x and y that satisfy all three inequalities, and they are represented by the region in the x-y plane that is common to all three. The feasible solutions can be found by shading the region below each of the lines representing the inequalities, and the set of feasible solutions is the region that is common to all three shaded regions.

Step-by-step explanation:

From the two points shown in the graph, we can write the equation of the line.

(5, 1975), (8, 3025)

slope = m = (y_2 - y_1)/(x_2 - x_1) = (3025 - 1975)/(8 - 5) = 1050/3 = 350

y = mx + b

y = 350x + b

1975 = 350 × 5 + b

b = 225

and 90 second is equal to 01 and half minutes.

Therefore, 04 minutes and 10 seconds consists 250 second.

Second:

The second is the critical unit of time. The default unit of time in the SI system of units. It can be defined as the time required for an electromagnetic field to propagate through a vacuum of 3 x 10 5 km.

1 solar day consists of 86,400 seconds. One minute is 60 seconds.

Minutes:

Minutes are a significant unit of time. Equal to 60 seconds. One hour includes 60 minutes. Minutes can be expressed as min. Included in the SI measurement system.

The amount will be after 4 years at interest rate of 6%, $624.76

To calculate the total amount you will pay after borrowing $500 for 4 years at an annual interest rate of 6%, you can use the formula for compound interest:

A = P x (1 + r/n)^(nt)

where:

A is the total amount,

P is the principal amount (the initial amount borrowed),

r is the annual interest rate as a decimal,

n is the number of times interest is compounded per year,

t is the number of years the money is borrowed for.

In this case, P = $500, r = 6%, n = 1  and t = 4.

So, the formula becomes:

A = $500 x (1 + 0.06/1)^(1 x 4)

A = $500 x (1.06)⁴

A = $500 x 1.249536
