Explanation of why Method A is recommended to save the fish from pesticide contamination

Explanation:

The method I would recommend to save the fish is Method A. Here's why:

Given the urgency and the higher rate of removal, Method A is the best choice to ensure the survival of the fish after the contamination event.

When you reflect a function in the x-axis, the first coordinate of a point stays the same, and the second coordinate changes sign (what was positive is now negative and vice versa).  See the attached picture.

Question 11:  f(x) = -5x + 2.  The function changes to its opposite, so g(x) = -(-5x + 2) = 5x - 2.

When you reflect a function in the y-axis, the first coordinate of a point changes to its opposite, but the second coordinate stays the same.  Replace  x  with  -x .

Question 14:  f(x) = |2x - 1| + 3.  Replacing x with -x produces  g(x) = |2(-x) - 1| + 3  which simplifies to  g(x) = |-2x -1| + 3.

Question 15 works the same way as #14.

Let's assume

x is number of hours worked

y is amount paid

Since, this is linear relationship

We can select any two points

(2,36.50) and (4,73)

so, we can also write as

x1=2 , y1 =36.50

x2=4 , y2=73

Firstly, we can find slope

[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

we can plug values

[tex]m=\frac{73-36.50}{4-2}[/tex]

[tex]m=18.25[/tex]

now, we can use point slope form of line

[tex]y-y_1=m(x-x_1)[/tex]

we can plug values

[tex]y-36.50=18.25(x-2)[/tex]

now, we can solve  for y

[tex]y=18.25x[/tex]

or

[tex]y=18.3x[/tex]..............Answer

Solution

The general form of the n-th term = a + (n-1)d

Here we are given the 1st term (a) = 10

6th term = 40

We need to find the 20th term.

Let's find the common difference.

6th term = 10 + (6 - 1) d

6th term is 40, so

40 = 10 + (6 -1)d

40 -10 = 5d

30 = 5d

d = 30/5

d = 6

The common difference is d = 6.

20th term = a + (n -1)d

= 10 + (20 -1)6

= 10 + 19*6

= 10 + 114

20th term = 124

This is a Mathematics problem about perimeter. If Brian has 25ft of fencing and one side of the rectangle is 9ft, the equation created is 2x =16. Solving for x gives the other dimension as 8ft which means the kennel's dimensions are 9ft by 8ft.

The subject of this question is Mathematics and it involves a problem of perimeter in geometry. In this problem, Brian has 25ft of fencing and one side of the rectangular area, the one against the garage, doesn't need fencing, and that side is 9ft.

Let the other side be 'x'. In a rectangle, opposite sides are equal. Since one of the sides is already fenced, we need fencing for only three sides. So we can create the equation 9 + x + x = 25. This simplifies to 2x = 16. Therefore, 'x' equals 8. The dimensions of the rectangular kennel are 9ft by 8ft.

This is the Pythagorean theorem, that equation is a^2 + b^2 = c^2, but if you dont have b you can manipulate the equation, that equation is c^2-a^2=b^2. So you take 15^2 - 12^2 and that equals 81, then you take the square root of 81, which equals 9, so your answer would be 9 feet. Hope that helped :)

The unknown side of the right-angled triangle measures 9 feet. We found this using the Pythagorean theorem.

This problem falls under the topic of Pythagoras theorem in Mathematics. The Pythagorean theorem describes the relationship between the lengths of the sides of a right-angled triangle. It is stated as: a² + b² = c², where c represents the length of the hypotenuse, and a and b are the lengths of the other two sides of the triangle.

If one side (say, a) of the right triangle is 12 feet and the hypotenuse (c) measures 15 feet, we can calculate the length of the other side (b) using the principle of the Pythagorean Theorem. By rearranging the theorem to solve for 'b', we get the equation:

b = √(c² - a²)

Substitute the given values into the equation:

b = √((15)² - (12)²) = √(225 - 144) = √81

Hence, the unknown side 'b' measures 9 feet.

To find the scale factor  the ratio of one length to the other is determined.

The scale factor is a measurement for comparing figures with similar appearances but differing scales or metrics.

Consider two squares that appear to be similar yet have different length of side.

The scale factor describes how much a figure has grown or shrunk in comparison to its original size.

Scale Factor is determined by dividing the new figure dimensions with the original figure.

For scale up the formula is Dimensions of the bigger figure / Dimensions of the smaller one.

Joseph earns $15 for every lawn he mows. Is the amount of money he earns proportional to the number of lawns he mows? Make a table to help you identify the type of relationship.

First let's start by making a table. I've attached an image of my drawing of the table and how it should look like. Feel free to comment below any questions you may have! :)

The type of relationship is definitely proportional, as for every lawn Joseph mows he gains 15 dollars. The relationship would be y = 15x, where y represents Joseph's earnings and x represents the number of lawns Joseph mows.

Hope this helped you!

To identify the type of Relationship between the amount of money Joseph earns and the number of lawns he mows, we can create a table and analyze the values. The relationship is directly proportional, meaning the amount of money Joseph earns increases proportionally as the number of lawns mowed increases.

To identify the type of relationship between the amount of money Joseph earns and the number of lawns he mows, we can create a table. Let's say the number of lawns he mows is represented by x and the amount of money he earns is represented by y.

We can start by assigning different values to x and calculating the corresponding values of y. For example, if Joseph mows 1 lawn, he would earn $15. If he mows 2 lawns, he would earn $30, and so on. After creating the table, we can analyze the relationship.

In this case, we observe that the amount of money Joseph earns is directly proportional to the number of lawns he mows. This means that as the number of lawns increases, the amount of money Joseph earns also increases proportionally.

Answer:

The slope is 3/4.

Step-by-step explanation:

Slope formula:

[tex]\displaystyle \frac{y_2-y_1}{x_2-x_1}[/tex]

[tex]\displaystyle \frac{(-2)-4}{(-8)-0}=\frac{-6}{-8}=\frac{-6\div2}{-8\div2}=\frac{-3}{-4}=\frac{3}{4}[/tex]

Therefore, the slope is 3/4, and the correct answer is 3/4.

if the lines are parallel the slopes are the same so m=5

the equation of a line given the slope and a point is

y-y1 = m(x-x1)

y-14= 5(x-2)

y-14 = 5x-10

y=5x+4

The vertical angles are congruent (or equal) so,

32 = 2x

2x = 32

2x/2 = 32/2 ..... dividing both sides by 2

x = 16 which is the answer

X=16 because 16 x 2=32 and both sides look pretty equal so.

We are given : Number of diagonals of a polygon = 1127 diagonals.

We know relation between number of diagonals and number of sides of the polygon.

Plugging d=1127 in above formula, we get

[tex]\frac{n(n-3)}{2}=1127[/tex]

Multiplying both sides by 2, we get

[tex]n(n-3)=2254[/tex]

[tex]n^2-3n=2254[/tex]

[tex]n^2-3n-2254=0[/tex]

Solving quadratic equation by factoring, we get factors

[tex]\left(n-49\right)\left(n+46\right)=0[/tex]

Solving for n, we get

n-49=0

n=49.

n+46=0.

n=-46.

We can't take number of sides by a negative number.

Therefore, number of sides does the polygon have 49 side.

The answer to the question "37 is what percent of 144 to the nearest percent?" is therefore 26%.

Answer:

(-1)^2 = +1

Step-by-step explanation:

(-1)(-1) is equivalent to (-1)^2, and vice versa.  Recall that when two negative numbers are mult. together, the product is positive.  Thus, (-1)^2 = +1.

Based on the definition of the square of a negative number, the result of (-1)² is: 1.

The square of a number represented as "x" can be found by multiplying "x" by itself, expressed as x², where "x" represents the number being squared.

When you square a number, you multiply it by itself. In this case, you are squaring -1.

Calculation:

(-1)² = (-1) * (-1) = 1

So, (-1)² is equal to 1. The negative sign is squared along with the number, resulting in a positive value.

Answer:

The correct answer is D. I hope i help you))

The correct answer is Option D. The graphed function consists of a constant value of 5 for (x < 2) and a linear equation with a positive slope for ([tex]x \geq 2)[/tex]

The graph represents a piecewise function. Let’s analyze it step by step:

Left Segment (for (x < 2)):

The graph is a horizontal line at (y = 5).

This corresponds to the piecewise component (f(x) = 5) for (x < 2).

Right Segment (for [tex](x \geq 2))[/tex]:

The graph is an oblique line passing through points (2,5) and (5,8).

The slope of this line is [tex](\frac{8 - 5}{5 - 2} = 1).[/tex]

It intersects the y-axis at (y = -2).

This corresponds to the linear equation (f(x) = x + 3) for ([tex]x \geq 2[/tex]).

Therefore, the function graphed is a piecewise function with two parts:

For (x < 2): (f(x) = 5)

For [tex](x \geq 2)[/tex]: (f(x) = x + 3)
