All sides of the given rhombus measure 5 cm respectively.

A rhombus is a quadrilateral with four equal-length sides in planar Euclidean geometry.

The term "equilateral quadrilateral" refers to a quadrilateral whose sides all have equal lengths.

Quadrilaterals having four congruent sides are called squares.

Squares are rhombuses by definition since they are quadrilaterals with four congruent sides.

So, consider the following values: AC = 8 cm, BD = 6 cm, OD = OB = 3 cm, and OA = OC = 4 cm.

Now,

OB² + OC² = BC²

3²+ 4² = BC²

9 + 16 = BC²

25 = BC²

5 = BC

A rhombus has an equal number of sides.

Therefore, all sides of the given rhombus measure 5 cm respectively.

Probability is an area of mathematics that deals with numerical representations of how probable an event is to occur or how likely a statement is to be true. The probability of an occurrence is a number between 0 and 1, where 0 denotes the event's impossibility and 1 represents certainty. A probability is a number that represents the possibility or chance that a specific event will occur. Probabilities can be stated as proportions ranging from 0 to 1, as well as percentages ranging from 0% to 100%.

Here,

This question asks for the probability that none of the three daffodils selected from the south side of the building are between 46cm and 48cm.

Answer:

(- 11, - 4 )

Step-by-step explanation:

4x - 6y = - 20 → (1)

- 2x + 4y = 6 → (2)

multiplying (2) by 2 and adding to (1) will eliminate x

- 4x + 8y = 12 → (3)

add (1) and (3) term by term to eliminate x

0 + 2y = - 8

2y = - 8 ( divide both sides by 2 )

y = - 4

substitute y = - 4 into either of the 2 equations and solve for x

substituting into (1)

4x - 6(- 4) = - 20

4x + 24 = - 20 ( subtract 24 from both sides )

4x = - 44 ( divide both sides by 4 )

x = - 11

solution is (- 11, - 4 )

The function is increasing on the interval (-∞, ∞). Therefore, the correct graph is graph (c).The function f(x) = -2x^5 can be graphed using a graphing utility. On the interval -2 to 2.25, we can approximate any local maxima and local minima.

So, let's begin by graphing the function using an online graphing utility such as Desmos. The graph of the function is as follows:Graph of f(x) = -2x^5 on the interval -2 to 2.25We can see from the graph that there is only one local maximum at around x = -1.3 and y = 4.68. There are no local minima on the interval. Now, to determine where f is increasing and where it is decreasing, we need to look at the sign of the maxima derivative of f.

The derivative of f is f'(x) = -10x^4. The sign of f' tells us whether f is increasing or decreasing. f' is positive when x < 0 and negative when x > 0. Therefore, f is increasing on (-∞, 0) and decreasing on (0, ∞). Now, let's look at the second part of the question. For the function g(x) = 26x^5 + 2, we can also graph it using Desmos. The graph of the function is as follows:Graph of g(x) = 26x^5 + 2As we can see from the graph, there are no local maxima or minima. The function is increasing on the interval (-∞, ∞). Finally, for the function h(x) = 4sin(x/10), we can also graph it using Desmos. The graph of the function is as follows:Graph of h(x) = 4sin(x/10)As we can see from the graph, there are no local maxima or minima.

Answer:

y = - 9x + 14

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

calculate m using the slope formula

m = \(\frac{y_{2}-y_{1} }{x_{2}-x_{1} }\)

with (x₁, y₁ ) = (- 4, 50 ) and (x₂, y₂ ) = (5, - 31 )

m = \(\frac{-31-50}{5-(-4)}\) = \(\frac{-81}{5+4}\) = \(\frac{-81}{9}\) = - 9 , then

y = - 9x + c ← is the partial equation

to find c substitute either of the 2 points into the partial equation

using (5, - 31 )

- 31 = - 9(5) + c = - 45 + c ( add 45 to both sides )

Proportional reasoning refers to the ability to compare and analyze relationships between two or more quantities that change in a consistent way. It involves understanding the concept of proportionality and applying it to solve problems.

1.) If a business jet burns 300 gallons of gasoline per hour, it burns 900 gallons of gasoline in a three-hour flight. This can be calculated by multiplying the burn rate of 300 gallons per hour by the duration of the flight, which is three hours.

2.) On average, one gallon of gasoline weighs approximately six pounds. Therefore, fifty gallons of gasoline weighs 300 pounds. This can be calculated by multiplying the weight of one gallon (six pounds) by the quantity of fifty gallons.

3.) For every one yard, there are thirty-six inches. To find the number of yards in 2,124 inches, we divide 2,124 by 36. The result is 59 yards. This can be calculated by dividing the total number of inches by the conversion factor of thirty-six inches per yard.

4.) A person who weighs 240 pounds burns 180 calories per mile of running. A person who weighs 48 pounds, burns thirty-six calories while running one mile. To find the number of pounds for which the person burns thirty-six calories while running one mile, we can set up a proportion. If we let x represent the weight in pounds, the proportion would be: 240 pounds / 180 calories = x pounds / 36 calories. Solving for x gives us x = 48 pounds.

5.) A rice casserole recipe serves four people and requires two tablespoons of butter. If a rice casserole requires six tablespoons of butter, it serves twelve people. This can be determined by setting up a proportion: 4 people / 2 tablespoons = 12 people / 6 tablespoons. Solving for the unknown number of people gives us 12 people.

Answer:

125°

Step-by-step explanation:

Sum of all the internal angles in a triangle is 180°

So, we have,

67°+58°+ Adjacent angle of 1 = 180°

125°+Adjacent angle of 1 = 180°

Adjacent angle of 1 = 180° - 125° = 55°

Angle 1 and its adjacent angle are supplementary

So, Angle 1 + Adjacent angle of 1 = 180°

Angle 1 + 55° = 180°

Angle 1 = 180° - 55° = 125°

Answer:

  A.) P(t) = 130t +3330

  B.) P(16) = 5410

Step-by-step explanation:

Given the ordered pairs (t, P(t)) = (2, 3590) and (9, 4500), you want a linear model that describes the relation. You also want the value of P(16).

We can write the formula for P(t) starting with the point-slope equation for P in terms of t. To do that, we need the slope:

  m = (P2 -P1)/(t2 -t1)

  m = (4500 -3590)/(9 -2) = 910/7 = 130

The point-slope equation will be ...

  P -P1 = m(t -t1)

  P -3590 = 130(t -2)

Solving for P, we find ...

  P = 130t -260 +3590 . . . . . eliminate parentheses, add 3590

  P(t) = 130t +3330

The value of P(16) will be ...

  P(16) = 130(16) +3330 = 2080 +3330 = 5410

The moose population is predicted to be 5410 in 2006.

To find a second solution, y2(x), for the given differential equation y" + 2y' + y = 0 using the reduction of order or the formula y2 = y1(x)∫e^(-∫P(x)dx)y1^2(x)dx, we will substitute the given solution y1(x) = xe^(-x) into the formula.

The second solution is y2(x) = e^(-2x) (Option C).

To explain the solution, let's start by substituting y1(x) = xe^(-x) into the formula for y2(x):

y2(x) = xe^(-x) ∫e^(-∫(2x)dx)(xe^(-x))^2dx

Simplifying the expression, we have:

y2(x) = xe^(-x) ∫e^(-2x)(x^2e^(-2x))dx

Integrating the expression inside the integral, we get:

y2(x) = xe^(-x) ∫(x^2e^(-4x))dx

Integrating this expression, we find:

y2(x) = xe^(-x) (-1/4) * (x^2e^(-4x) - 2∫xe^(-4x)dx)

Simplifying further, we have:

y2(x) = xe^(-x) (-1/4) * (x^2e^(-4x) - 2(-1/4)e^(-4x))

Finally, simplifying the expression, we obtain:

y2(x) = xe^(-x) (1/4) * (x^2e^(-4x) + (1/2)e^(-4x))

This can be further simplified as:

y2(x) = (1/4) * x^3e^(-5x) + (1/8) * xe^(-5x)

Therefore, the second solution is y2(x) = e^(-2x) (Option C).

When the second derivative of a function equals zero, it indicates a possible point of inflection or a critical point where the concavity of the function changes. It is a significant point in the analysis of the function's behavior.

The second derivative of a function measures the rate at which the slope of the function is changing. When the second derivative equals zero at a particular point, it suggests that the function's curvature may change at that point. This means that the function may transition from being concave upward to concave downward, or vice versa.

Mathematically, if the second derivative is zero at a specific point, it is an indication that the function has a possible point of inflection or a critical point. At this point, the function may exhibit a change in concavity or the slope of the tangent line.

Studying the second derivative helps in understanding the overall shape and behavior of a function. It provides insights into the concavity, inflection points, and critical points, which are crucial in calculus and optimization problems.

When the second derivative of a function equals zero, it indicates a critical point in the function, which can be a maximum, minimum, or an inflection point.

The second derivative of a function measures the rate at which the slope of the function is changing. When the second derivative equals zero, it indicates a critical point in the function. A critical point is a point where the function may have a maximum, minimum, or an inflection point.

To determine the nature of the critical point, further analysis is required. One method is to use the first derivative test. The first derivative test involves examining the sign of the first derivative on either side of the critical point. If the first derivative changes from positive to negative, the critical point is a local maximum. If the first derivative changes from negative to positive, the critical point is a local minimum.

Another method is to use the second derivative test. The second derivative test involves evaluating the sign of the second derivative at the critical point. If the second derivative is positive, the critical point is a local minimum. If the second derivative is negative, the critical point is a local maximum. If the second derivative is zero or undefined, the test is inconclusive.

When two variables vary along with each other but the data points are loosely scattered around the line of best fit, the correlation is weak correlation.

We need to find the type of correlation when two variables vary along with each other but the data points are loosely scattered around the line of best fit.

A scatter plot helps find the relationship between two variables. This relationship is referred to as a correlation. Based on the correlation, scatter plots can be classified as follows.

A weak positive correlation indicates that, although both variables tend to go up in response to one another, the relationship is not very strong. A strong negative correlation, on the other hand, indicates a strong connection between the two variables, but that one goes up whenever the other one goes down.

Therefore, when two variables vary along with each other but the data points are loosely scattered around the line of best fit, the correlation is weak correlation.

a. The sampling method that I would use for the given scenario is stratified random sampling.

b. The sampling method that I would use for the given scenario is systematic sampling.

Stratified random sampling is the most effective way to get accurate results in this situation. The university wants to conduct a mail survey of its alumni to collect information about their current employment status to justify charging a higher tuition rate than other universities. Stratified random sampling divides the population into strata based on certain characteristics.

In this case, strata would be the alumni that have different degrees from the university. The information collected through this method will be more representative of the population than simple random sampling. It ensures that each stratum is represented accurately in the sample. It also minimizes the variability within each stratum. It is an effective way of ensuring that each stratum is properly represented.  

Systematic sampling involves selecting every kth element from a list of the population. In this situation, the Environmental Protection Agency (EPA) wants to inspect a sample of 1000 containers from the 40,000 containers known to be in landfills to determine if leakage from the containers has occurred. As the exact location of the containers is no longer known, systematic sampling can be used.

EPA can select every 40th container from the list of the population, as 40,000/1000 = 40. In this way, they will have a random sample of 1000 containers from the 40,000 containers. This sampling method is less time-consuming and more cost-effective than other sampling methods. It also ensures the sample is representative of the entire population.

Answer:

x=9

Step-by-step explanation:

10+x/3=13

(given)

x/3=3

(subtract 3 on both sides)

x=9

(multiply 3 on both sides)

Answer:

Subtract 10 both sides to get x/3 = 3

Then Multiply 3 to both sides,

x = 9
