Answer:

113 feet

Step-by-step explanation:

I will assume you meant h = -4.9t^2 + 135; "t2" is incorrect.

To answer this question, to find the height of the ball after 2.1 seconds, substitute 2.1 for t in the above equation:

h(2.1) = -4.9(2.1)^2 + 135.  This becomes -21.6 + 135, or 113.4.

The closest result to the height of the ball after 2.1 seconds is 113 feet.

In general, whether or not an individual needs to file a tax return depends on a number of factors, including income, filing status, and age.

In the United States, for example, the IRS sets income thresholds each year, and individuals whose income exceeds these thresholds are generally required to file a tax return.

However, there are many exemptions and exceptions to this general rule, and individuals should consult the IRS website or a tax professional for more information specific to their situation.

Other countries may have different rules and requirements for filing tax returns, so it's important to check with the tax authority in your own country for specific guidance.

The probability of the second cm is:

Now the probability of the two pulls:

Answer:

After 17,190 years, the amount of carbon-14 left would be approximately 5 mg.

The half-life of carbon-14 is 5,730 years, which means that every 5,730 years, half of the remaining carbon-14 decays. To calculate the amount of carbon-14 remaining after 17,190 years, we can use the formula:

A = A0 * (1/2)^(t/T)

where:

A0 is the initial amount (80 mg)

t is the time elapsed (17,190 years)

T is the half-life (5,730 years)

A = 80 * (1/2)^(17,190/5,730)

A = 80 * (1/2)^3

A = 80 * (1/8)

A = 10 mg * 1/2

A = 5 mg

The  radius of the new sphere of dough is 5.3368

In the given statement is :

Two spherical pieces of cookie dough have radii of 3 centimeters and 5 centimeters, respectively. The pieces are combined to form one large spherical piece of dough.

To find the approximate radius of the new sphere of dough

V 1 = 4/2 · 3³ π = 108/3 π

V 2 = 4/3 · 5³ π = 500/3 π

The new sphere:  V = V 1 + V 2 = 608/3 π

4/3 r³ π = 608/3 π  / : π/3

4 r³ = 608

r³ = 608 : 4 = 152

r = ∛152

r = 5.3368 cm

If Joel and Duncan split the 15 ounces of hot chocolate evenly, then they each got half of the container.

To find out how much hot chocolate each boy got, we need to divide the total amount of hot chocolate by the number of people sharing it. Since there are two boys, we can divide 15 by 2 to get the amount of hot chocolate each boy received: 15 ÷ 2 = 7.5

Therefore, each boy got 7.5 ounces of hot chocolate to drink while they went sledding.It's important to note that when dividing something equally between two people, we divide by two since there are two individuals.

In this case, each boy received half of the container, or half of the total amount of hot chocolate. This type of division is known as "fair" or "equal" sharing, as both parties receive an equal portion.

The correct answer is A. no; since np<5, the normal distribution should not be used.  This is because np<5, which violates the condition for using the normal distribution approximation to the binomial distribution. In this case, np=15 which is less than 5, and therefore, the binomial distribution should be used. If np is greater than or equal to 5, a normal approximation to the binomial distribution can be used.

The binomial distribution can be used to model the probability of a certain number of successes in a fixed number of independent trials, where the probability of success in each trial is the same. However, if the number of trials is large and the probability of success is small, the binomial distribution can be approximated by a normal distribution.

In this case, we have

n = 100 trials and p = 0.15

probability of success in each trial.

Therefore, np = 15, which is less than 5. According to the rule of thumb, if np < 5 or n(1-p) < 5, the normal distribution approximation is not valid, and the binomial distribution should be used.

Since the probability of success is small (0.15), and the number of trials is relatively large (100), we could use a normal approximation to the binomial distribution. However, since np < 5, we cannot use the binomial probability formula directly. Instead, we would need to use a continuity correction and the standard normal distribution to estimate the probability. Therefore, option A is the correct answer.

After 4 hours of discharging, the volume left in the tank would be 500 liters. The correct option is C.

Initially, the tank has a water capacity of 1500 liters.

After three hours of discharging, half of the water is discharged, which means 1500/2 = 750 liters have been removed from the tank.

To find the volume left after 4 hours of discharging, we need to subtract the additional amount discharged in the fourth hour.

Since the discharge rate remains the same, we can calculate the amount discharged in one hour as 750/3 = 250 liters.

Therefore, in the fourth hour, 250 liters would be discharged. Subtracting this from the remaining water after three hours (750 liters), we get 750 - 250 = 500 liters.

Therefore, the correct answer is c. 500 liters.

Answer:

Angle 1 = 115 degrees

Angle 2 = 65 degrees

Step-by-step explanation:

Angle 1: Same-side interior angle of Line 1

Angle 2: Same-side interior angle of Line 2

We know that the difference between the angles is 50 degrees. Since the angles are supplementary, we can write the equation:

Angle 1 + Angle 2 = 180

Now, we need to express the difference between the angles in terms of Angle 1 or Angle 2. We can choose either angle, so let's express it in terms of Angle 1:

Angle 1 - Angle 2 = 50

We can rewrite this equation as:

Angle 1 = 50 + Angle 2

Now substitute this expression for Angle 1 into the first equation:

(50 + Angle 2) + Angle 2 = 180

Combine like terms:

2Angle 2 + 50 = 180

Subtract 50 from both sides:

2Angle 2 = 130

Divide by 2:

Angle 2 = 65

Now substitute this value back into the equation for Angle 1:

Angle 1 = 50 + Angle 2

Angle 1 = 50 + 65

Angle 1 = 115

Therefore, the angles are as follows:

Angle 1 = 115 degrees

Angle 2 = 65 degrees

Using the orthonormality of ∣+⟩ and ∣−⟩, it can be proven that [S i, S j] = iϵ ijk ℏS k, and {S i, S j} = (ℏ^2/2)δ ij, where δ ij and ϵ ijk are Kronecker's delta function and the completely anti-symmetric symbol, respectively, and S x = 2ℏ (∣+⟩⟨−∣ + ∣−⟩⟨+∣), S y = 2iℏ (∣+⟩⟨−∣ − ∣−⟩⟨+∣), and S z = 2ℏ (∣+⟩⟨+∣ − ∣−⟩⟨−∣).

To prove the commutation relation [S i, S j] = iϵ ijk ℏS k, and the anti-commutation relation {S i, S j} = (ℏ^2/2)δ ij, we need to apply the orthonormality properties of the states ∣+⟩ and ∣−⟩. These states are eigenstates of the Pauli spin operators S x, S y, and S z, as provided in the question.

By expanding the commutator [S i, S j] and using the orthonormality relations, we can derive the result iϵ ijk ℏS k. Similarly, by expanding the anti-commutator {S i, S j} and utilizing the orthonormality relations, we obtain the result (ℏ^2/2)δ ij.

These commutation and anti-commutation relations are fundamental properties of the Pauli spin operators, which are widely used in quantum mechanics. They play a crucial role in describing the angular momentum and spin properties of particles, particularly in systems with spin-1/2 particles.

Understanding these relations is essential for studying quantum mechanics and its applications, such as quantum computing and quantum information processing. They provide a mathematical framework for describing the behavior and interactions of quantum systems, and they have significant implications for various physical phenomena.

We can infer that the function's vertex is (0, 0) because its terminus is located at the origin (0, 0). As a result, k = 0 and h = 0.

We can start by figuring out the fundamental structure of a radical function, and then apply the knowledge we have gained to solve for the particular problem.

A radical function's generic form is given by:

f(x) = a√(x - h) + k

f(x) = a√(x - 0) + 0

f(x) = a√x

3 = a√(-16)

3 = a√(-1)√16

3 = a√(-1)4

Since the square root of -1 is denoted as "i" (imaginary unit), we have:

3 = 4ai

Solving for a:

a = 3/(4i)

As a result, the radical function's equation, which has its terminus at the origin and passes through the point (-16, 3), is as follows: f(x) = (3/(4i))√x
