The domain and range of the the function are -

Domain → [0, 180]

Range → [600, 1050]

The domain of a function f(x) is the set of all values for which the function is defined, and the range of the function is the set of all values that function takes.

Given is that the owners of a recreation area filled a small pond with water in 180 minutes. The pond already had some water at the beginning. The graph {attached below} shows the amount of water (in liters) in the pond versus time (in minutes).

Domain is the set of all possible {x} values. We can write -

Domain → [0, 180]

Range is the set of all possible {y} values. We can write -

Range → [600, 1050]

Therefore, the domain and range of the the function are -

Domain → [0, 180]

Range → [600, 1050]

Answer:

Step-by-step explanation:

so

120 = 2x

x = 120 : 2

x = 60

120 = 2 x 60

120 = 120

Answer:

You do length time width

Answer:

4x-2y=8

or, 4x = 8+2y

or x = 8+2y/4-----(eq.1)

2x-3y=12-----(eq.2)

Now,

putting value of eq.1 in eq.2, we get

2x-3y=12

or, (8+2y/4)-3y = 12

or, 8-10y/4=12

or, 8-10y=12×4

or,8-10y=48

or,-10y=48-8

or,y=40/-10

or, y = -4

again,

2x-3y=12

or, 2x-3×-4=12

or, 2x+12=12

or, x=0

In 1st option

4x-2y=8

or,4×0-2×-4=8

or,0+8=8

8=8

2x-3y=12

2×0-3×-4=12

0+12=12

12=12

So 1st option is true

Hope this helps, sorry I don't have an explanation...

The use of if__name__ == '__main__' in python is to check whether the current script is being run on its own or being imported somewhere else by combining it with if statement.

Here we need to find the use of if __ name __ == '__ main __' in Python.

Basically, in python the term Allows You to Execute Code When the File Runs as a Script, but Not When It’s Imported as a Module

Here for most practical purposes, this is known as the conditional block that you open with if __name__ == "__main__" as a way to store code that should only run when your file is executed as a script.

Therefore, the function is used as  a variable defined for each script that defines whether the script is being run as the main module or it is being run as an imported module.

Answer:

The area of x is 4

The area of the right triangle is 6

Step-by-step explanation:

The Pythagorean Theorem can be used when dealing with right triangles. So, if we use the equation a^2 + b^2 = c^2, we can find that 3^2 + x^2 = 5^2 or 9 + x^2 = 25. If we calculate, we can find that x is equal to 4. Now if we multiply by 3 and divide by 2, we can get the answer of 6 as the area of the right triangle.

The true equations are - 15·0 = 015·0, 1.4 + 2.7 = 4.1, and 4(2/3) = 5-(1/3).

What is an equation?

A mathematical definition of an equation is a claim that two expressions are equal when they are joined by the equals sign ("=").

The first equation is -

5 + 0 = 0

This equation is false, as if 0 is added to any number, the result is the same number itself, and not 0.

The second equation is -

15·0 = 015·0

Any number multiplied by 0, gives the result as 0.

In the above equation LHS = RHS = 0.

Hence, this equation is true.

The third equation is -

1.4 + 2.7 = 4.1

Solving LHS -

= 1.4 + 2.7

= 4.1

So, LHS = RHS and hence, this equation is true.

The fourth equation is -

(2/3) · (5/9) = 7/12

Solving LHS -

= (2/3) × (5/9)

= 10/27

Here, LHS ≠ RHS.

Hence, this equation is false.

The fifth equation is -

4(2/3) = 5-(1/3)

Solving LHS -

4(2/3) = 14/3

Solving RHS -

= 5 - 1/3

= (15 - 1)/3

= 14/3

Therefore, LHS = RHS and hence, this equation is true.

By adding the squares of the triangle's two smaller sides and comparing the result to the square of a largest side, you may determine whether triangle is acute, obtuse, or right.

The equilateral triangle comes first. All three sides of this triangle are the same length, and each angle measures exactly 60 degrees. An equilateral triangle is Triangle A.

This triangle has two acute angles, which are angles smaller than 90 degrees in length, but one right angle (as well as angle which measures 90 degrees). A right triangle is triangle B.

The isosceles triangle is another. This triangle has two sides that are the same length.

The scalene triangle comes next. This triangle has three different lengths for its three sides.

The acute triangle is the next type of triangle and has three acute angles.

The obtuse triangle is the last triangle. Two of the angles of this triangle are sharp, and one of the angles is obtuse, which is defined as being more than 90 degrees.

Thus, by adding the squares of the triangle's two smaller sides and comparing the result to the square of a largest side, you may determine whether triangle is acute, obtuse, or right.

Answer: 5/6

Step-by-step explanation: Another way of writing this problem is 2/1 ÷ 12/5. To solve this division problem, you must multiply the recipricol of the divisor. The recipricol of 12/5 is 5/12, so the new expression will look like this: 2/1 x 5/12. You can solve this by multiplying the numorators and then multiplying the denonimators to get 10/12. The simplified version of 10/12 can be expressed as 5/6.

By using simple arithmetic and using calculator we get:

Arithmetic is a branch of mathematics that deals with the manipulation of numbers and their properties. It is the study of numbers and the operations that can be performed on them, such as addition, subtraction, multiplication, and division. Arithmetic also includes concepts such as fractions, decimals, and percentages. The study of arithmetic is fundamental to many other branches of mathematics, including algebra, geometry, and calculus, as well as many practical fields like finance, engineering, and computer science.

A calculator is a device that performs mathematical calculations. It can be a handheld device or a software program on a computer or mobile device. Calculators typically have buttons or keys for performing basic arithmetic operations, such as addition, subtraction, multiplication, and division, as well as more advanced functions like trigonometry and logarithms. Some calculators also have the ability to store and recall numbers, perform conversions between units of measurement, and perform other specialized functions.

By probability, she will not receive a phone call from any of her grandchildren after 146 days

In those circumstances, probability helps in assessing the likelihood of an event. Probability plays a significant role in daily life. political strategy analysis, blood type determination, sports and gaming strategies, insurance buying or selling, online shopping, and online gaming.

There is a [tex]\frac{2}{3}[/tex] chance that the first child won't call, a [tex]\frac{3}{4}[/tex] chance that the second child won't call, and a [tex]\frac{4}{5}[/tex] chance that the third child won't call on any given day. There is a [tex]\frac{2}{3} *\frac{3}{4} * \frac{4}{5} = \frac{2}{5}[/tex] chance that no child calls her on a randomly selected day.

When we consider a sample of 360 days, in particular, this "unrigorous" reasoning becomes rigorous due to linearity of expectation; over the first 360 days, 360 * 2/5 = 144 days will pass without a phone call. Now, we just check the remaining days. On days $361 and $362, no one calls her. On days 363 and 364, she receives calls from children every three and four days, respectively. On day 365, she receives calls every five days. Therefore, to get our answer of 146, we two more days in  144.

y = -3x + 12   is the equation  for the line containing the side opposite the side containing the first two vertices.

Given coordinates:

(-3,4) ; (-2,1) ; and (2,6)

let us solve for the slope.

Since , parallel sides have the same slope.

m = y2-y1 / x2-x1

m = 1 - 4 / -2-(-3)

m = -3 / 1

m = -3

y = mx + b

Since , (2,6) is a point which passes through the line . Hence , it must satisfy the equation.

Therefore,

6 = -3(2) + b

6 = -6 + b

6 + 6 = b

12 = b

On Substituting , values of m and b in y = mx +b , we get y = -3x +12 which is the required equation of the line.

Hence, y = -3x + 12   is the equation  for the line containing the side opposite the side containing the first two vertices.
