Answer:

base 4 and height of 10

base 8 and height 5

Step-by-step explanation:

The area of the rectangle is 20. 4 x 5 = 20

The area of a triangle is  \(A = \frac{1}{2}bh\)

Multiply two numbers together that equal 40 because you are going to take half of 40 to get 20.

4 x 10 = 40

40/2 = 20

8 x 5 = 40

40/2 = 20

The answer is a ≤ 30.

An inequality is a mathematical expression that compares two values or expressions using an inequality operator. In this case, the inequality would be a ≤ 30. This means that the area of the triangle must be less than or equal to 30 square inches.

This can be solved by finding the area of the triangle. To do this, we need to know the lengths of the sides of the triangle. Suppose we have sides p, q, and r. Then the area of the triangle can be found using the formula:

                       a = 1/2 × b × h

where q is the base of the triangle and r is the height. To ensure that the area of the triangle is no more than 30 square inches, the inequality must be satisfied. That is, 1/2 × b × h ≤ 30. This inequality can be rewritten in terms of the side lengths by substituting 1/2 × q × r for h. This gives us a ≤ 30.

No, Morgan is not correct. If the diameter of the second circle is twice as long as the diameter of the first circle, then the area of the second circle will be four times as great as the area of the first circle, not twice as great.

Circle is a shape consisting of all points in a plane that are at a given distance from a given point, the centre.

No, Morgan is not correct. If the diameter of the second circle is twice as long as the diameter of the first circle, then the area of the second circle will be four times as great as the area of the first circle, not twice as great.

The formula for the area of a circle is given by:

A = πr^2

Where A is the area and r is the radius. The radius of the first circle is half the length of its diameter, so if its diameter is d, then its radius is d/2.

If the diameter of the second circle is twice as long as the diameter of the first circle, then its radius will be 2 * d/2 = d, and its area will be:

A = πd^2 = π(2d/2)^2 = 4π(d/2)^2 = 4A

So the area of the second circle is four times as great as the area of the first circle, not twice as great.

The value of x is 2yw + y - 1 for the given equation 2x + 2/y = 4w + 2.

According to the given question.

We have an equation

2x + 2/y = 4w + 2

Since, we have to find the value of x for the given equation

2x + 2/y = 4w + 2

Thereofore,

2x + 2/y = 4w + 2

⇒ 2(x + 1)/y = 2(2w + 1)    (taking 2 common from both the sides)

⇒ (x + 1)/y = 2w + 1

⇒ (x + 1) = y(2w + 1)         (multiplying both the sides by y)

⇒ x + 1 = 2yw + y

⇒ x = 2yw + y - 1         ( subtracting 1 both the sides)

Hence, the value of x is 2yw + y - 1 for the given equation 2x + 2/y = 4w + 2.

Answer:

The segment that connects the midpoints of the legs of a trapezoid is called the median of the trapezoid.

Step-by-step explanation:

The absolute maximum value occurs at x = -2, where f(x) is 20.

Therefore, the answer is E. -2.

Here, we have,

To find the absolute maximum value of the function f(x) = x³ - 3x² + 12 on the closed interval [-2, 4], we need to evaluate the function at the critical points within the interval and at the endpoints.

Evaluate f(x) at the critical points:

To find the critical points, we take the derivative of f(x) and set it equal to zero:

f'(x) = 3x² - 6x

Setting f'(x) = 0 and solving for x:

3x² - 6x = 0

3x(x - 2) = 0

From this equation, we find two critical points: x = 0 and x = 2.

Evaluate f(x) at x = 0:

f(0) = (0)³ - 3(0)² + 12 = 12

Evaluate f(x) at x = 2:

f(2) = (2)³ - 3(2)² + 12 = 2

Evaluate f(x) at the endpoints of the interval:

Evaluate f(x) at x = -2:

f(-2) = (-2)³ - 3(-2)² + 12 = 20

Evaluate f(x) at x = 4:

f(4) = (4)³ - 3(4)² + 12 = -8

Now, we compare the function values at the critical points and endpoints to determine the absolute maximum value:

f(-2) = 20

f(0) = 12

f(2) = 2

f(4) = -8

The absolute maximum value occurs at x = -2, where f(x) is 20.

Therefore, the answer is E. -2.

True: When a form is created based on two or more tables, a relationship must be defined between queries.

True. When a form is created based on two or more tables, a relationship must be defined between queries in order to ensure that the form displays accurate data. Queries are used to pull data from multiple tables and present it in a single view, so it is important to define the relationships between these tables to avoid inconsistencies or errors in the displayed data. This ensures that the data from the related tables can be properly displayed and managed within the form.

When you drag and search a field from an "other" (unrelated) table, a new one-to-many relationship is created from the table in the list and the table from which you dragged the field. This relationship is established by Access, which does not enforce integrity by default.

Step-by-step explanation:

The angle of a body segment with respect to a fixed line of reference is known as a "relative angle."

The angle of a body segment with respect to a fixed line of reference is known as a reference angle. This angle is measured between the segment and the reference line, and is used to determine the position and orientation of the segment relative to other parts of the body or external objects. The segment itself refers to a specific part of the body, such as an arm, leg, or torso, that is bounded by two or more joints or points of attachment. By measuring the reference angle of a segment, it is possible to quantify the degree of movement or displacement of that segment, and to track changes in its position over time.
In this context, the angle represents the measurement of the difference in orientation between the body segment and the reference line, while the segment refers to a specific part of the body, such as an arm or leg. The reference line serves as a fixed point for comparison, allowing you to determine the position or orientation of the body segment in relation to it.

The value of n in the n-sided polygon, with sides AC and AD, where the external angle formed at the point the decagon touches the n-sided polygon is 60° is; n = 15

A polygon is a planar shape with three or more straight sides.

The sum of angles at a point property indicates that, the sum of angles at the point A can be presented as follows;

∠BAC + ∠CAD + ∠DAB = 360°

Angle ∠BAC = 60°

Angle ∠DAB is an interior angle of a 10-sided regular polygon, (a decagon),  therefore, the measure of angle ∠DAB is 144°

Plugging in the values of the measures of the angles ∠BAC and ∠DAB, in the equation, ∠BAC + ∠CAD + ∠DAB = 360°, we get;

+ ∠CAD + 144° = 360°

∠CAD = 360° - (144° + 60°) = 156°

∠CAD = 156°

The formula for finding the measure of the interior angle of an n-sided polygon, θ, can be presented as follows;

θ = (n - 2) × 180°/n

Where the interior angle, θ = 156°, which is the measure of ∠CAD, in the n-sided polygon, we get;

156° = (n - 2) × 180°/n

156·n = 180·n - 360

360 = 180·n - 156·n = 24·n

Rainbow punch, made by Frutayuda, Inc., was sold in 12-ounce cans to benefit victims of Hurricane Zero. The mean number of ounces placed in a can by an automatic fill pump is 11.7 ounces with a standard deviation of 0.18 ounce. Assuming a normal distribution, the probability that more than 12 ounces will be released by the pump and overflow the can is 0.02275.

This can be calculated by finding the probability that the filling pump will cause a can to have an amount less than 12 ounces. This probability can be calculated by finding the area under the normal distribution curve from 11.7 to 12. To do this, the z-score of 11.7 must be found. This z-score is -1.05.

The area under the curve from -1.05 to 0 is 0.1587. Subtracting this from 1 gives 0.8413, which is the probability that the filling pump will cause a can to have an amount less than 12 ounces. This means that the probability that the filling pump will cause an overflow in a can is 0.02275 (1-0.8413 = 0.02275).

Step 1: There are four consecutive integers that add up to - 362

Step 2: Let's write the equation to find the four consecutive integers, as follows:

• Let x to represent the first consecutive integer

• Let x + 1 to represent the second consecutive integer

• Let x + 2 to represent the third consecutive integer

• Let x + 3 to represent the fourth consecutive integer

Therefore,

x + x + 1 + x + 2 + x + 3 = -362

Step 3: Let's solve for x

4x + 6 = -362

Subtracting 6 at both sides:

4x + 6 - 6 = -362 - 6

4x = -368

Dividing by 4 at both sides:

4x/4 = -368/4

x = -92

Step 4: Let's find the four consecutive integers based on x = -92

To find L{f(t)}, we first need to know the definition of the Laplace transform.  Laplace Transform Definition: The Laplace transform of a function f(t) is defined as  L{f(t)} = ∫[0,∞) e^(-st) f(t) dt, where s is a complex variable.

The Laplace transform is a mathematical tool used to transform a function of time into a function of complex frequency, s. This tool is often used in engineering and physics to solve differential equations and analyze systems.
To find L{f(t)}, we need to use the Laplace transform definition and substitute f(t) into the integral.

Assuming that the function f(t) is known, we can use the Laplace transform definition to find L{f(t)}.
L{f(t)} = ∫[0,∞) e^(-st) f(t) dt
Let's assume that f(t) = sin(t).
L{sin(t)} = ∫[0,∞) e^(-st) sin(t) dt
We can use integration by parts to solve this integral.
Let u = sin(t) and dv = e^(-st) dt.
Then, du/dt = cos(t) and v = (-1/s) e^(-st).
Using integration by parts, we get:
L{sin(t)} = [-1/s * e^(-st) * sin(t)]∞[0] - ∫[0,∞) [-1/s * e^(-st) * cos(t)] dt
Simplifying this expression, we get:
L{sin(t)} = [-1/s * e^(-s∞) * sin(∞)] - [-1/s * e^(0) * sin(0)] - (1/s) ∫[0,∞) e^(-st) cos(t) dt
Since sin(∞) and sin(0) are both zero, we can simplify further to get:
L{sin(t)} = (1/s) ∫[0,∞) e^(-st) cos(t) dt
We can use integration by parts again to solve this integral.
Let u = cos(t) and dv = e^(-st) dt.
Then, du/dt = -sin(t) and v = (-1/s) e^(-st).
Using integration by parts, we get:
L{sin(t)} = (1/s) [(-1/s * e^(-st) * cos(t)]∞[0] - (1/s) ∫[0,∞) [-1/s * e^(-st) * (-sin(t))] dt
Simplifying this expression, we get:
L{sin(t)} = (1/s^2) [cos(0) - cos(∞)] - (1/s^2) L{-cos(t)}
Since cos(0) = 1 and cos(∞) = undefined, we can simplify further to get:
L{sin(t)} = 1/(s^2 + 1)
Therefore, the Laplace transform of f(t) = sin(t) is L{f(t)} = 1/(s^2 + 1).

There are 625 possible combinations.

According to the multiplication principle, if an event A can happen in x different ways and an event B can happen in y different ways, then there are x y possibilities for both events to happen at once.

To determine the number of combinations possible with 4 cards and a spinner with 5 numbers, we can use the concept of the multiplication principle.

For the spinner, we have 5 possible numbers that can be selected.

For the 4 cards, each card can have any one of the 5 possible numbers from the spinner.

Using the multiplication principle, we multiply the number of choices for each item together to find the total number of combinations.

Number of combinations = Number of choices for the spinner × Number of choices for each card

                       = 5 × 5 × 5 × 5
