The graph of line a and line b is shown in the image attached below. The lines do not intersect each other.

To check if both lines intersect, we need to graph the system of equations. First, use the points given to write out the equations.

Line a:

Slope (m) = change in y / change in x = 6 - 4 / 8 - 0 = 2/8

m = 1/4

Find the y-intercept (b) by substituting m = 1/4, x = 0 and y = 4 into y = mx + b:

4 = 1/4(0) + b

b = 4

The equation of line a is: y = 1/4x + 4.

Line b:

Slope (m) = change in y / change in x = 1 - (-2) / 8 - 0

m = 3/8

Find the y-intercept (b) by substituting m = 3/8, x = 0 and y = -2 into y = mx + b:

-2 = 3/8(0) + b

b = -2

The equation of line b is: y = 3/8x - 2.

Both lines are graphed in the image attached below. Line a is the red line and line b is the red line. They do not intersect at any point.

The temperature of an apple pie during the time it spends in the oven shows the continuous relationship.

In mathematics, a continuous function is a function that does not have discontinuities that means any unexpected changes in value. A function is continuous if we can ensure arbitrarily small changes by restricting enough minor changes in its input.

A function f(x) is said to be a continuous function in calculus at a point x = a if the curve of the function does NOT break at the point x = a.

A continuous function, on the other hand, is a function that can take on any number within a certain interval. For example, if at one point, a continuous function is 1 and 2 at another point, then this continuous function will definitely be 1.5 at yet another point.

Therefore, option C and E are the correct answers.

After considering the given data we conclude that the satisfactory value which always true for the given function is  \(\pi\).

To evaluate the value of \(\pi\phi\) such that \(sin (t + \pi\phi) = -sin (t),\) we can apply the following steps:
Applying the trigonometric identity \(sin (a + b) = sin a cos b + cos a sin b\) to restructure \(sin (t + \pi\phi)\)as \(sin t cos \pi\phi + cos t sin \pi\phi\).
Set this expression equivalent to\(-sin t: sin t cos \pi\phi + cos t sin \pi\phi = -sin t.\)
Factor out sin t: \(sin t (cos \pi\phi + 1) = 0.\)
Evaluating for \(\pi\phi: cos \pi\phi = -1.\)
The value of \(\pi\phi\) that gradually satisfy this equation is\(\pi\phi\) = \(\pi\).
Therefore, the answer is (e) \(\pi\).

5. To solve the first question related to triangle, we can use Pythagorean theorem and  by using the formula, A = 1/2 * b * h

Area of the triangles are 48.5, 28.4 and 20.1.

6) The three side lengths of 9ft, 14ft, and 15ft form an acute triangle.

7) The three side lengths of 6km, 8km, and 10km form a right triangle.

This type of triangle is determined by the length of the sides and the measure of the angles. Acute triangles have all angles measuring less than 90 degrees.

5. To solve the first question related to triangle, we can use Pythagorean theorem.

By following the given information, let us divide the triangle into 2 sections.

Triangle 1 with 11 as the longest side. It is shown that the height of the triangle is perpendicular to its base.

For Triangle 1, two of its sides are given, 9 is the base and 11 is the hypotenuse.

So, according to the Pythagorean theorem,

hypotenuse² = base²+ perpendicular²

11² = 9² + perpendicular²

11² - 9² = perpendicular²

40 = perpendicular²

perpendicular = √40

perpendicular = 6.3

Now, for Triangle 2, we found the value of the perpendicular and the hypotenuse is given as 9.

So, by again using Pythagorean theorem,

hypotenuse² = base²+ perpendicular²

9²- 6.3² =  base²

41.6 =  base²

base = √41.6

base =6.4

Thus, the value of the base of the Triangle is 9+6.4=15.4

Now, the area of the overall triangle can be found by using the formula,

A = 1/2 * b * h

Here, the base is 15.4 and the height is 6.3.

A = 1/2 * 15.4 * 6.3

A = 1/2 * 97

A = 48.5 square

Area of triangle 1=

A = 1/2 * 9 * 6.3

A = 1/2 * 56.7

A = 28.4 square

Area of triangle 2=

A = 1/2 * 6.4 * 6.3

A = 1/2 * 40.3

A = 20.1 square

6) The three side lengths of 9ft, 14ft, and 15ft form an acute triangle. This can be determined by using the Pythagorean Theorem.

In this case, the squares of the two shorter sides are 9² + 14² = 277, and the square of the hypotenuse is 15² = 225.

Therefore, the three side lengths form an acute triangle, as the sum of square of two shorter sides is greater than the square of the longer side.

7) The three side lengths of 6km, 8km, and 10km form a right triangle. This can be determined by using the Pythagorean Theorem.

In this case, the squares of the two shorter sides are 6² + 8² = 100, and the square of the hypotenuse is 10² = 100. Therefore, the three side lengths form a right triangle, as the sum of square of two shorter sides is equal to the square of the longer side.

Answer:  The height is 5.2 cm.

Step-by-step explanation:

146.952 = n r^2 h

146.952= 3.14 * 9 *h

146.952= 28.26 h  divide both sides by 28.26

h = 5.2

false :) thats ur answer

To show h(t) = |r(t)|², where r(t) is a complex-valued function, we need to first find the magnitude of r(t) and then square it.

Let r(t) = x(t) + i y(t) be a complex-valued function, where x(t) and y(t) are the real and imaginary parts of r(t), respectively. The magnitude of r(t) is given by |r(t)| = √(x(t)² + y(t)²), which is the distance of the point (x(t), y(t)) from the origin in the complex plane.

To find |r(t)|², we simply square the magnitude, i.e., |r(t)|² = (x(t)² + y(t)²).

Therefore, h(t) = |r(t)|² = (x(t)² + y(t)²),

which is the sum of the squares of the real and imaginary parts of r(t).

In the case where r(t) is a real-valued function, i.e., y(t) = 0, then h(t) reduces to h(t) = r(t)².

The concepts of additive relationship and multiplicative relationship are given as follows:

An additive relationship exists when the change in one variable corresponds to a fixed change in another variable. For example, if the cost of buying a certain number of apples is $10, and the cost of buying twice as many apples is $20, then we have an additive relationship between the number of apples purchased and the cost.

On the other hand, a multiplicative relationship exists when the change in one variable corresponds to a fixed multiple of another variable. For example, if the interest earned on a bank account is proportional to the amount of money in the account, then we have a multiplicative relationship between the interest earned and the amount of money in the account.

To solve this problem, let's represent the unknown number as "x". According to the given information, the number is multiplied by 10 and then 25 is added to the result. So, the expression for this operation is 10x + 25.

Now, if we add 113 to this expression and multiply the whole sum by 6, we should get the same answer.

The expression for this operation would be 6 * (10x + 25 + 113).

To find the value of x, we can set these two expressions equal to each other and solve for x.

So, we have: 10x + 25 = 6 * (10x + 25 + 113).

Expanding the right side of the equation, we get: 10x + 25 = 60x + 420.

Moving all the terms involving x to one side, we have: 10x - 60x = 420 - 25.

Simplifying, we get: -50x = 395.

To isolate x, we divide both sides of the equation by -50: x = 395 / -50.

Simplifying the division, we find that x = -7.9.

Therefore, the number you were thinking of is -7.9.

The surface area of a square pyramid net can be found by adding the areas of the base and the four triangular faces.

First, find the area of the base by multiplying the length and width of the square base.

Area of base = length × width

Next, find the area of one of the triangular faces by using the formula:

Area of triangle = 0.5 × base × height

Since there are four triangular faces in a square pyramid, multiply the area of one triangle by four to find the total area of the triangular faces.

Area of triangular faces = 4 × (0.5 × base × height)

Finally, add the area of the base and the area of the triangular faces to find the total surface area of the square pyramid net.

Surface area = Area of base + Area of triangular faces

= (length × width) + (4 × (0.5 × base × height))

= (length × width) + (2 × base × height)

So, the surface area of a square pyramid net is the sum of the area of the base and the area of the four triangular faces.

Step-by-step explanation:

In an observational study, lurking variables are present but not explicitly accounted for in the study design. These variables may have an effect on the outcome variable and can lead to confounding.

Lurking variables are variables that are not directly measured or controlled in a study, but can affect the relationship between the variables of interest. They can lead to confounding, which is when the effect of one variable on the outcome cannot be separated from the effect of another variable. In an observational study, it can be more difficult to identify and control for lurking variables, which can weaken the ability to draw causal conclusions.

Blinding is a technique used in some studies to reduce bias by hiding the treatment or condition from either the participants, the researchers, or both. In a single-blind study, either the participants or the researchers are unaware of the treatment or condition, while in a double-blind study, both the participants and the researchers are unaware. Blinding can help reduce bias by preventing expectations from influencing the results.

Confounding occurs when the effect of one variable on the outcome cannot be separated from the effect of another variable. This can lead to incorrect conclusions about the relationship between the variables of interest. For example, in a study looking at the relationship between coffee consumption and heart disease, age could be a lurking variable that affects both coffee consumption and the risk of heart disease. If age is not controlled for, it could lead to a false conclusion about the relationship between coffee consumption and heart disease.

Random assignment is a technique used in experimental studies to assign participants to different treatments or conditions at random, which helps to ensure that the groups are similar in all aspects except for the treatment or condition. This reduces the potential for confounding and helps to establish a causal relationship between the treatment or condition and the outcome.
