The equation of the blue line in the given graph is y = -x/2 + 2   .

In the question ,

a line graph is given,

we have to find the equation of the blue line .

to find the equation of line , we need at least two points ,

So , from the graph we can see that the two points from where the blue line passes the graph are (4,0)  and (0,2) .

the slope = (2-0)/(0-4)

m = 2/(-4)

m = -1/2

So , the equation of the line passing from the points (4,0) with slope -1/2 , is

(y - y₁) = m(x - x₁)

y - 0 = (-1/2)(x - 4)

y = -x/2 + 2

Therefore , The equation of the blue line in the given graph is y = -x/2 + 2   .

As per the given function, the local minimum is 1 and the local maximum is 9 and it can be written as (1, 9)

Local Minimum and maximum

The term Local maxima and minima are the maxima and minima of the function that arises in a particular interval.

Here the Local maxima would be the point in the particular interval for which the values of the function near that point are always less than the value of the function at that point.

Whereas the local minima would be defined as the point where the values of the function near that point are greater than the value of the function at that point.

Given,

Here we have the function f is increasing on the interval (1, 4) and decreasing on the interval (4, 9).

Here we need to determine and explain whether there is a local maximum or local minimum on the interval (1, 9).

According to the definition of the local minimum and local maximum,

While we looking into the given point,

We have identified that the resulting point is

=> (1, 4) => 1 (minimum)

=> (4, 9) => 9 (maximum)

Therefore, the minimum and maximum is (1, 9).

A continuous function that has a domain of [-3, 4]  will include all the values as -3,-2,-1,-0,-1,-2,3,4

What do you mean by continuous function?

In mathematics, a continuous function is one where a continuous variation of the argument results in a continuous variation of the function's value (i.e., a change without a leap). This indicates that there aren't any discontinuities, or sudden changes in value. More specifically, a function is continuous if it is possible to guarantee that its value will not vary significantly even with arbitrarily tiny changes to its parameter. Any function that is not continuous is said to be discontinuous.

It is given that a continuous function has a domain of [-3,4]

According to the definition of closed interval,

[-3,4] will contain all the elements between them and including them.

Therefore, [-3,4] will contain elements as -3,-2,-1,-0,-1,-2,3,4

Hence, a continuous function that has a domain of [-3, 4]  will include all the values as -3,-2,-1,-0,-1,-2,3,4

What is the property of a similar triangle?

Two triangles are similar if their corresponding angles are equal and their corresponding sides are within the same ratio (or proportion).

Given

You are standing such that a 63-foot tree is directly between you and the sun.

If you are standing 240 feet away from the tree and the tree casts a 270-foot shadow.

BC to be the height of the tree and DE to be the height of how tall you could be and still be completely in the shadow of the tree.

∠D = ∠B = 90 degrees

Therefore,

By the similar triangle property;

DE/BC = AD/AC

x/63 = (270-240)/270

x/63=30/270=0.11

x=63*0.11 = 7

Step-by-step explanation:

The percent markup is 11.11%.

There is a department store. The total number of shirts bought by the department store is 400. The total cost of the shirts bought by the department store is $10,800. The department store sells all the shirts for $30 each. We need to find the percent markup.

We first need to find out the cost of each shirt. The cost price of each shirt is the total cost of all the shirts divided by the total number of shirts bought by the department store.

C = $10,800/400

C = $27

Hence, each shirt was purchased for a price equal to $27. To find the markup percentage, we need to find the percentage difference between the cost price and the selling price of the shirt.

M = [(30 - 27)/27]*100%

M = (3/27)*100%

M = 100/9%

M = 11.11%

The length of the line is 18 units.

If there are two point P( a, b) and Q (c, d) then the distance between P and Q is

d= √ ( c- a)² + ( d- b)²

Given points: ( -10 ,9 ) and ( 5, -1)

So, the distance between these two points

Using Distance formula

d= √ ( c- a)² + ( d- b)²

d = √(5 - (-10))² + (- 1- 9)²

d= √15² + (-10)²

d= √225+ 100

ΔABC is not a right angled triangle.

What is right angled triangle?

A right-angle triangle is one that has angles between its two sides that equal 90 degrees.

Main Body:

First let's find the length of the last side. We can do this by adding AB and BC together, then subtracting this amount from the perimeter of Triangle ABC, 22 cm.

ABC - (AB + BC) ⇒ 22 - (8 + 5)

                             =22 - 13 = 9 cm

The hypotenuse is always the longest side of a triangle, so we know that the side we figured out is the hypotenuse. Now we can use the Pythagorean Theorem to see whether the triangle is a right triangle.

Pythagorean Theorem: a² + b² = c², where a and b are legs and c is the hypotenuse.

If a² + b² do equal c², then the triangle is a right triangle.

⇒8² + 5² = 9²

⇒64 + 25 = 81

⇒89 > 81

Therefore triangle is not a right triangle, but we know that it is obtuse since a and b together are longer than c.

The ratio between the fruit and vegetable is 1:3

Ratio shows how many times one number contains another. For example, if there are eight oranges and six lemons in a bowl of fruit, then the ratio of oranges to lemons is eight to six. Similarly, the ratio of lemons to oranges is 6:8 and the ratio of oranges to the total amount of fruit is 8:14. The ratio is defined as the comparison of two quantities of the same units that indicates how much of one quantity is present in the other quantity. Ratios can be classified into two types. One is part to part ratio and the other is part to whole ratio.

We can simply say that a ratio is a fraction of one quantity over another quantity

In this case, we just have to figure the ratio between fruit and vegetables.

In the first column, we have fruit to vegetable as 2:6 = 1:3

In the second column, we have fruit missing. We can make that x.

Using the ratio between fruit and vegetable, when vegetable is 12, the fruit will be 12/3 = 4

The value of fruit in the second column will be 4.

The probability of a type I error in the case of the new blood test is 0.022.

Given;

It is not always possible to identify rare diseases by screening. A blood test that has been created by researchers is thought to be reasonably dependable. In 97% of those who suffer from a sickness, it produces a favorable response. However, 5% of those tested who do not have the condition received an incorrectly positive response. Take into account the null hypothesis that "the person does not have the disease."

A: The individual does not have the disease

B: The individual does have the disease

We know that,

Type I Error is rejecting the true null hypothesis

P (Type I Error) = P(Positive reaction to an individual who does not have the disease)

Step-by-step explanation:

The area of the circular table is 1075.21 square inches.

Jada has a table. The table is circular in shape. She paints the table. The diameter of the circular table is 37 inches. We need to find out the area of the table. We will, first of all, find the radius of the circular table. Let the radius and the area of the table be represented by the variables "r" and "A", respectively.

The radius of a circle is equal to half its diameter.

r = 37/2

r = 18.5 inches

To find the area of the table, we will use the formula for the area of a circle.

A = πr²

A = π(18.5)²

A = 1075.21

Hence, the area of the circular table is 1075.21 square inches.
