Which of the following expressions represents the distance between − 4 3 − 3 4 ​ minus, start fraction, 4, divided by, 3, end fraction and 1 3 3 1 ​ start fraction, 1, divided by, 3, end fraction?

Step-by-step explanation:

The potential energy stored in the spring can be calculated using the equation:

PE_spring = 1/2 * k * x^2

where k is the spring constant and x is the displacement of the spring from its rest position. In this case, x = 0.5 m.

The potential energy stored in the rope can be calculated as the gravitational potential energy of the object, which is given by:

PE_rope = m * g * h

where m is the mass of the object (10 kg), g is the acceleration due to gravity (9.8 m/s^2), and h is the vertical displacement of the object.

The horizontal and vertical components of the displacement can be calculated using trigonometry:

x = 0.5 * cos(30) = 0.5 * sqrt(3)/2 m

y = 0.5 * sin(30) = 0.5/2 m

The total potential energy stored in the spring and rope is given by the sum of their individual potential energies:

PE = PE_spring + PE_rope = 1/2 * k * x^2 + m * g * h

Substituting in the given values, we find:

PE = 1/2 * k * (0.5 * sqrt(3)/2)^2 + 10 * 9.8 * (0.5/2 + 0.3)

Note: The spring constant (k) is not given, so the answer is given in terms of k.

Answer:

Step-by-step explanation:

The potentpotentialial energy stored in a spring is calculated by 1/2 * k * x^2, where k is the spring constant and x is the displacement from its rest position. The potential energy stored in the rope is calculated as m * g * h, where m is the object's mass, g is acceleration due to gravity and h is the object's vertical displacement. The total potential energy is the sum of these two energies. In this case, the horizontal and vertical components of the displacement can be calculated using trigonometry and then used to find the total potential energy stored in the spring and rope.

To balance a see-saw, the product of the distance of the person's weight from the pivot and their weight must be equal on both sides.

Let's call Daniela's mass "m".

The force on Lucy's side is:

distance * weight = 3.5 meters * 50 kg = 175 kg * meters

The force on Daniela's side is:

distance * weight = d * m

Since the see-saw is balanced, the two forces must be equal:

3.5 * 50 = d * m

Solving for m, we get:

m = 175 / d

Without knowing the distance "d" that Daniela is sitting from the pivot, it is impossible to calculate her weight.

The value of the cubic polynomial evaluated at x = 0.5 is equal to 8.

In this problem we find the case of a cubic polynomial in standard form:

y = a · x³ + b · x² + c · x + d

Where a, b, c, d are real coefficients.

The values of the coefficients must be determined on the knowledge of the leading coefficient (a = 2), the constant term (d = 5) and two values (y(- 1) = 2, f(1) = 14). First, substitute the leading coefficient and the constant term in the definition:

The volume of the buoy is the sum of volume of hemisphere and volume of cone which is 0.504m³

To calculate the volume of the buoy, we need to find the volume of the hemisphere and the volume of the cone.

The volume of a hemisphere can be calculated using the formula:

V = (2/3) * π * (r^3)

where "r" is the radius of the hemisphere.

So, the volume of a hemisphere with radius "r" is equal to (4/3) times π times the cube of the radius.

The base is 0.95 and the radius is half the length of the base.

radius = 0.95 / 2 = 0.475m

The volume of the hemisphere = 2/3 * 3.14 * 0.475³

volume of hemisphere = 0.224m³

The volume of the cone = 1/3 πr²h

The volume of the cone = 1/3 * 3.14 * 0.475² * 1.2

The volume of the cone = 0.28m³

Answer:

the area of each cookie made by Tony is approximately 63.62 square cm.

Step-by-step explanation:

The area of a cookie can be found if we know its radius. To find the radius, we can divide the circumference by 2 times pi (π).

Let's call the radius of the cookie "r".

45 cm / (2 * π) = r

Now that we have the radius, we can find the area using the formula:

π * r^2 = area

So,

π * r^2 = π * (45 / (2 * π))^2 = (45^2) / (4 * π)

Therefore, the area of each cookie made by Tony is approximately 63.62 square cm.

The extraneous solutions of the equation is -2 and 15.

ln stands for logarithm and it is a function that returns the power to which a certain number (base) must be raised to obtain a given value. The logarithm is commonly used to simplify mathematical expressions and can be thought of as an inverse operation to exponentiation.

In this equation, we have two logarithmic expressions on the left and right side. To solve for x, we need to find what number raised to the power of the base (ln), will result in x² - 30 and 13x.

So, if we find the height for one triangle, we can find the height for the other triangle. To do this, we will use the logarithmic property:

ln(aᵇ) = b * ln(a)

Where a and b are any positive real numbers.

Applying this property to both logarithmic expressions, we get:

ln(x² - 30) = ln((x² - 30)^(1/ln)) = 1/ln * ln(x² - 30)

Equating the two, we get:

1/ln * ln(x² - 30) = 1/ln * ln(13) + 1/ln * ln(x)

Dividing both sides by 1/ln, we get:

ln(x² - 30) = ln(13) + ln(x)

Using the logarithmic property, we can simplify further:

x² - 30 = 13 * x

Dividing both sides by x, we get:

x²/x - 30/x = 13

x - 30/x = 13

x² - 30 = 13x

x² - 13x - 30 = 0

This is a quadratic equation and can be solved using the quadratic formula:

x = (-b ± √(b² - 4ac)) / 2a

Where a = 1, b = -13, c = -30

So,

x = (-(-13) ± √((-13)^2 - 4 * 1 * -30)) / 2 * 1

x = (13 ± √(169 + 120)) / 2

x = (13 ± √289) / 2

x = (13 ± 17) / 2

So,

x = (13 + 17) / 2 = 15 or

x = (13 - 17) / 2 = -2

These are the two solutions to the equation. To check for extraneous solutions, we substitute x = 15 and x = -2 back into the equation and see if it is true.

The probability that it lands heads at least once is 1.0720.

Probability is the measure of the likelihood of an event occurring. In this case, we are looking at the probability of a coin landing heads at least once after three tosses.

Let's denote the event of the coin landing heads on the first toss as event A, the event of the coin landing heads on the second toss as event B, and the event of the coin landing heads on the third toss as event C.

The probability of landing heads at least once is equal to the sum of the probabilities of each individual event occurring (A, B, or C) minus the probability of all three events occurring (A and B and C).

P(A or B or C) = P(A) + P(B) + P(C) - P(A and B and C)

Since the coin is unfair and has a probability of 0.4 of landing heads, P(A) = P(B) = P(C) = 0.4.

Using the formula for the probability of multiple events happening simultaneously, we find that P(A and B and C) = P(A) * P(B) * P(C) = 0.4 * 0.4 * 0.4 = 0.064.

Plugging in all the values, we get:

P(A or B or C) = 0.4 + 0.4 + 0.4 - 0.064 = 1.136 - 0.064 = 1.072

Rounding to four decimal places, the answer is 1.0720, which means that the probability of the coin landing heads at least once after three tosses is 1.0720.
