The tip of the woman's shadow is moving away from the pole at a rate of 16/3 ft/s when she is 36 ft from the base of the pole.

Let x be the distance of the woman from the pole, and let y be the length of her shadow on the ground. Since the sun's rays are parallel, the triangles formed by the woman, her shadow, and the pole are similar triangles. Therefore, we can use the following proportion:

(woman's height) / (length of woman's shadow) = (height of pole) / (total length of pole's shadow)

Substituting the given values, we get:

5 / y = 15 / (x + y)

Cross-multiplying and simplifying, we get:

3y = 5(x + y)

3y = 5x + 5y

2y = 5x

y = (5/2)x

We can now differentiate both sides of this equation with respect to time t:

dy/dt = (5/2)dx/dt

We want to find dx/dt when x = 36 ft. To do this, we need to find y when x = 36 ft:

y = (5/2)x = (5/2)(36) = 90 ft

Now we can substitute x = 36 ft and y = 90 ft into the differentiated equation:

dy/dt = (5/2)dx/dt

Solving for dx/dt, we get:

dx/dt = (2/5)dy/dt

We know that dy/dt is the rate at which the woman's shadow is changing, which is given by her walking speed of 4 ft/s. Therefore, dy/dt = 4 ft/s. Substituting this value, we get:

dx/dt = (2/5)(4) = 8/5 ft/s

Therefore, the tip of the woman's shadow is moving away from the pole at a rate of 8/5 ft/s, which is equivalent to 1.6 ft/s or 16/3 ft/s.

An engine is a machine designed to convert fuel into mechanical energy that can be used to power other machines or devices. In the context of automobiles, an engine is the primary source of power that drives the vehicle. It typically operates by burning fuel in a combustion chamber to generate high-pressure gases that drive a piston, which in turn rotates a crankshaft that ultimately powers the car's wheels.

Car color and number of miles driven are characteristics or properties of a car, while an engine is a component that helps to power the car. Driving, on the other hand, is an action or behavior associated with a car, as it refers to the act of operating or using the car to travel from one place to another.

There are 35 different 3-digit numbers that can be formed using the digits 0, 1, 2, 3, 4, 5, 6, if the repetition of digits is not allowed.

Probability is a branch of mathematics that deals with the study of randomness and uncertainty in events. It is the measure of the likelihood or chance that an event will occur. Probability is expressed as a number between 0 and 1, where 0 indicates that the event will not occur and 1 indicates that the event will occur with certainty.

To form a 3-digit number using the given set of 7 digits (0, 1, 2, 3, 4, 5, 6) without repetition, we need to choose 3 different digits from the set.

We can count the number of ways to select 3 distinct digits from the set of 7 using the combination formula, which is:

C(n, k) = n! / (k! * (n-k)!)

Where n is the total number of items in the set, and k is the number of items we want to choose.

In this case, n = 7 (because we have 7 digits to choose from), and k = 3 (because we want to choose 3 digits to form a 3-digit number).

Therefore, the number of ways to select 3 distinct digits from the set of 7 is:

C(7, 3) = 7! / (3! * 4!)

= (7 * 6 * 5 * 4 * 3 * 2 * 1) / ((3 * 2 * 1) * (4 * 3 * 2 * 1))

= (7 * 6 * 5) / (3 * 2 * 1)

= 35

It can be stated that a minimum of 90.82% of houses would fall within the price range of $418,500 to $621,500.

The given data are as follows:

Mean price (μ) = $520000

Standard deviation (σ) = $58000

Price range: $418500 to $621500

We are to find the percentage of homes priced between $418500 and $621500.To find the required percentage, we first need to standardize the given range of prices by converting them into z-scores.

The z-score formula is z = (x - μ) / σwhere x is the price, μ is the mean price, and σ is the standard deviation. So, for the lower limit: z₁ = (418500 - 520000) / 58000 = -1.75 And for the upper limit: z₂ = (621500 - 520000) / 58000 = 1.75

Now, we need to find the area under the normal curve between these two z-scores, which represents the percentage of homes priced between $418500 and $621500. To do this, we can use a calculator.

The area between $418500 and $621500 corresponds to the area between z₁ and z₂ on the standard normal distribution curve. The area between z₁ and z₂ is 0.9082 (rounded to 4 decimal places).

Therefore, we can say that at least 90.82% of homes would be priced between $418500 and $621500.

180 - x = 180 - 2x + 30

x = 30

Answer:

The measure of the unknown angle is 30°.

Step-by-step explanation:

Let the measure of the unknown angle be x°.

Supplementary angles are two angles whose measures sum to 180°.

Complementary angles are two angles whose measures sum to 90°.

Therefore, the supplement of x° is (180 - x)°, and its complement is (90 - x)°.

Given that the supplement is 30° more than twice its complement:

(180 - x)° = 2(90 - x)° + 30°

To find the measure of the angle, solve the equation:

⇒ (180 - x)° = (180 - 2x)° + 30°

⇒ 180° - x° = 180° - 2x° + 30°

⇒ 180° - x° = 210° - 2x°

⇒ 180° - x° + 2x° = 210° - 2x° + 2x°

⇒ 180° + x° = 210°

⇒ 180° + x° - 180° = 210° - 180°

⇒ x° = 30°

Therefore, the measure of the unknown angle is 30°.

Correlation refers to the relationship between two variables in a dataset. It is a statistical measure that quantifies the degree to which two variables are related to each other.

There are two types of correlation: positive and negative. Positive correlation exists when the two variables move in the same direction, meaning that as one variable increases, the other variable also increases. Negative correlation exists when the two variables move in opposite directions, meaning that as one variable increases, the other variable decreases.

The strength of the correlation can be measured using a correlation coefficient, which ranges from -1 to +1. A correlation coefficient of +1 indicates a perfect positive correlation, while a correlation coefficient of -1 indicates a perfect negative correlation. A correlation coefficient of 0 indicates no correlation between the two variables.

From the given graph, we can see that there is a positive correlation between the number of people in a group and the total number of balloons they pop. As the number of people in the group increases, the total number of balloons they pop also tends to increase.

The top of the ladder is coming down the wall at a rate of 15.39 ft/s

Let's assume that the ladder makes a right angle with the wall and the ground. Let's call the distance between the bottom of the ladder and the wall "x" and the height of the ladder at a given time t "y". We want to find the rate of change of "y" with respect to time "t", or dy/dt, when y = 8 ft.

We can use the Pythagorean theorem to relate "x" and "y":

x^2 + y^2 = 17^2

Taking the derivative of both sides with respect to time "t", we get

2x(dx/dt) + 2y(dy/dt) = 0

We want to find dy/dt when y = 8 ft and dx/dt = 2 ft/s. We can solve for dy/dt

2x(dx/dt) + 2y(dy/dt) = 0

2y(dy/dt) = -2x(dx/dt)

dy/dt = -x/y(dx/dt)

Substituting x = sqrt(17^2 - y^2) and dx/dt = 2 ft/s, we get:

dy/dt = -(17^2 - y^2)/y

When y = 8 ft, we get

dy/dt = -(17^2 - 8^2)/8 = -15.39 ft/s

Rounding to the nearest tenth, the approximate radius of the beach ball is 10.3 inches.

Answer:

Let's assume that the original size of the trial-size bottle of dishwashing soap is "x" ounces.

According to the problem, the new size of the bottle is 10% less than the original size, which means that the new size is 90% of the original size. So we can set up an equation as follows:

0.90x = 4.5

To solve for x, we need to isolate it on one side of the equation. We can do this by dividing both sides of the equation by 0.90:

x = 4.5 ÷ 0.90

x = 5

Therefore, the original size of the trial-size bottle of dishwashing soap is 5 ounces.
