Answer:

the answer is just ab

Step-by-step explanation:

dats what it is added up

The length of line segment AB is 12 inches for the given figure.

A secant is a straight line that touches a circle twice.

As per the given figure, we have

Secant segment  BD = (8+10) in.

External secant segment BC = 8 in.

Tangent segment = AB

When a secant segment and a tangent segment intersect at an exterior location, the square of the tangent segment's measure equals the product of the secant segment's and its external secant segment's measures.

So, AB² = BC × BD

Substitute the values in the above equation,

AB² = 8 × (8+10)

AB² = 8 × 18

AB² = 144

AB = 12

Thus, the length of line segment AB is 12 inches.

Answer:

Step-by-step explanation:

a. (I) x = 65

(ii) vertically opposite angles are equal.

b. (i) 71 degrees

(ii) alternate interior angles are equal

c. (i) z = 180 - 71 = 109 degrees

(ii) angles on a line add up to 180 degrees

Answer:

x = 65°, y = 71°, z = 44°

Step-by-step explanation:

x and 65 are vertical angles and congruent, thus

x = 65°

y and 71 are alternate angles and congruent, thus

y = 71°

The sum of the 3 angles in a triangle = 180°, thus

z = 180° - (65 + 71)° = 180° - 136° = 44°

Hence

x = 65°, y = 71° and z = 44°

8 ''A''-students out of 40 is bigger

Step-by-step explanation:

8 "A"-students out of 40:

\(\frac{8}{40}\) = \(\frac{1}{5}\) = 20%

9 "A"-students out of 50:

\(\frac{9}{50}\) = 18%

20% > 15%

8 ''A''-students out of 40 is bigger

The percentage of 8 ''A'' students out of 40 is more than 9 ''A''-students out of 50.

Given that, to determine which percent is bigger: 8 ''A''-students out of 40 or 9 ''A''-students out of 50.

The percentage is the ratio of the composition of matter to the overall composition of matter multiplied by 100.

Here,
According to the question,
8 ''A''-students out of 40 = 8 / 40 × 100%
                                         = 20%

9 ''A''-students out of 50 = 9 / 50 × 100%
                                         = 18%

Thus, the percentage of 8 ''A'' students out of 40 is more than 9 ''A''-students out of 50.

(C) Regression analysis is the statistical method commonly used to estimate the level and trend in a time series by modeling the relationship between the data and independent variables.

Regression analysis is the statistical method used to estimate the level and trend in a time series. Time series data represents observations taken at different points in time and is commonly used to analyze trends and patterns over time.

Regression analysis allows us to model the relationship between a dependent variable (in this case, the time series data) and one or more independent variables (such as time or other relevant factors). By using regression analysis, we can identify the underlying trend in the time series and estimate its level.

The regression model captures the relationship between the dependent variable (the time series) and the independent variable(s) by fitting a line or curve that best represents the data. This line or curve helps to identify the overall trend and level of the time series.

While moving average, simulation method, covariance analysis, and correlation analysis are useful techniques in analyzing time series data, they are not specifically designed to estimate the level and trend in a time series. Therefore, (C) regression analysis is the most appropriate method for estimating the level and trend in a time series.

Answer:

x=12

Step-by-step explanation:

This is a right triangle, so the Pythagorean theorem can be used. The Pythagorean theorem states that \(C^2=a^2+b^2\) where C is the hypotenuse and a and b are legs. In this question, we are given a and C. So, plugin 13 for C and 5 for a and solve for b. Once you rearrange the equation you get, \(b=\sqrt{13^2-5^2}\). Next, solve what is under the root to get, \(b=\sqrt{144}\). Finally, square root 144 for the final answer b=12.

Answer:

x = 12

Step-by-step explanation:

c² = a² + b²

13² = 5² + b²

169 = 25 + b²

b² = 169 - 25

b² = 144

b = 12

the solution for the initial value problem is: u(x, t) = sin(sqrt(-λ² * (a / 4)) * x) * exp(-λ² * t) where λ = ± sqrt(-4n² / a), and n is a non-zero integer.

The given partial differential equation is:

au(x, t) = 4 * (d²u(x, t) / dt²) / (dx²)

a) BCs (Boundary Conditions):

We have u(0, t) = 0 and u(π, t) = 0.

IC (Initial Condition):

We have u(x, 0) = x.

To solve this initial value problem, we need to find a function f(x) that satisfies the given boundary conditions and initial condition.

The solution for f(x) can be found using the method of separation of variables. Assuming u(x, t) = X(x) * T(t), we can rewrite the equation as:

X(x) * T'(t) = 4 * X''(x) * T(t) / a

Dividing both sides by X(x) * T(t) gives:

T'(t) / T(t) = 4 * X''(x) / (a * X(x))

Since the left side only depends on t and the right side only depends on x, both sides must be equal to a constant value, which we'll call -λ².

T'(t) / T(t) = -λ²

X''(x) / X(x) = -λ² * (a / 4)

Solving the first equation gives T(t) = C1 * exp(-λ² * t), where C1 is a constant.

Solving the second equation gives X(x) = C2 * sin(sqrt(-λ² * (a / 4)) * x) + C3 * cos(sqrt(-λ² * (a / 4)) * x), where C2 and C3 are constants.

Now, applying the boundary conditions:

1) u(0, t) = 0:

Plugging in x = 0 into the solution X(x) gives C3 * cos(0) = 0, which implies C3 = 0.

2) u(π, t) = 0:

Plugging in x = π into the solution X(x) gives C2 * sin(sqrt(-λ² * (a / 4)) * π) = 0. To satisfy this condition, we need the sine term to be zero, which means sqrt(-λ² * (a / 4)) * π = n * π, where n is an integer. Solving for λ, we get λ = ± sqrt(-4n² / a), where n is a non-zero integer.

Now, let's find the expression for u(x, t) using the initial condition:

u(x, 0) = X(x) * T(0) = x

Plugging in t = 0 and X(x) = C2 * sin(sqrt(-λ² * (a / 4)) * x) into the equation above, we get:

C2 * sin(sqrt(-λ² * (a / 4)) * x) * C1 = x

This implies C2 * C1 = 1, so we can choose C1 = 1 and C2 = 1.

Therefore, the solution for the initial value problem is:

u(x, t) = sin(sqrt(-λ² * (a / 4)) * x) * exp(-λ² * t)

where λ = ± sqrt(-4n² / a), and n is a non-zero integer.

Note: Please double-check the provided equation and ensure the values of a and the given boundary conditions are correctly represented in the equation.

The scenario that would result in an increase in productivity is when the total number of hours worked by the US labor force increases from 256 billion hours to 285 billion hours while the GDP stays at $20 trillion.

Productivity is a measure of output per unit of input, and in this case, the input is the total number of hours worked by the labor force. When the number of hours worked increases while maintaining the same level of GDP, it suggests that the labor force is becoming more efficient and productive.

By working additional hours without a corresponding decrease in GDP, the workforce is able to produce more output for the same amount of time invested. This increase in productivity can be attributed to factors such as improved efficiency, technological advancements, or better utilization of resources.

On the other hand, the other scenarios described do not necessarily indicate an increase in productivity. Maintaining the same GDP and hours worked or experiencing a decrease in GDP suggests stagnation or a decline in productivity, while an increase in GDP without a corresponding increase in hours worked does not necessarily reflect an improvement in productivity.

Step-by-step explanation:

Rate = Total number of customers / Total time

Rate = 14/7

Rate = 2

Therefore, the customers were entering the store at a rate of 2 customers per minute.

The final price of the pen is $1.76 after adding the markup percentages by both the wholesaler and the retailer.

The final price is the total amount of money that a customer pays to purchase a product or service. It includes the cost of the product or service plus any additional fees or charges, such as taxes or shipping costs.

The final price of the pen can be found by adding the markup percentages to the original price of $0.50.

Markup by the wholesaler = 60% of $0.50 = $0.30

Price after markup by wholesaler = $0.50 + $0.30 = $0.80

Markup by the retailer = 120% of $0.80 = $0.96

Final price of the pen = $0.80 + $0.96 = $1.76

Therefore, the final price of the pen is $1.76 after adding the markup percentages by both the wholesaler and the retailer.

For example, if a product costs $50 and there is a 10% sales tax, the final price would be $55 (50 + 5). Similarly, if a service costs $100 and there is a $10 delivery fee, the final price would be $110 (100 + 10).
