Step-by-step explanation:

A police officer can not punish air pollution but can enforce laws and regulations to protect the environment.

Air pollution means the presence of harmful substances in the air that can cause harm to all living beings.

We have,

Air pollution is not a living being so it can not be punished by a police officer.

A police officer or government authorities can enforce laws and regulations to reduce air pollution to protect all living beings and the environment.

Some of the measures are:

- Setting emissions standards for automobile and related industries

- Promoting the use of clean energy resources.

- Encouraging individuals and entities to adopt sustainable practices

Thus,

A police officer can not punish air pollution but can enforce laws and regulations to protect the environment.

Answer:

5/24

Step-by-step explanation:

Answer:

In the case of 4 tickets it can be possible

Step-by-step explanation:

Let us assume the number of tickets be t

Now as per the question the equations would be

For you  = t + $8

For your friend = t + $12

In the case when you both spend the same amount so the above equations would be equivalent to each other

t + $8 = t + $12

So here the tickets would be 4 so this is possible that you both spend the same amounts

Answer:

Step-by-step explanation:

f(x) = 1 - x²

g(x) = [tex]\sqrt{11-4x}[/tex]

[tex](\frac{f}{g})(x)=\frac{f(x)}{g(x)}[/tex]

[tex](\frac{f}{g})(x)=\frac{1-x^2}{\sqrt{11-4x}}[/tex]

[tex](\frac{f}{g})(-1)=\frac{1-(-1)^2}{\sqrt{11-4(-1)}}[/tex]

             = [tex]\frac{1-1}{\sqrt{15}}[/tex]

             = 0

(g + f)(x) = g(x) + f(x)

             = [tex]\sqrt{11-4x}+1-x^2[/tex]

(g + f)(2) = [tex]\sqrt{11-4(2)}+1-(2)^2[/tex]

             = [tex]\sqrt{3}-3[/tex]

(g - f)(x) = g(x) - f(x)

            = [tex]\sqrt{11-4x}-(1-x^2)[/tex]

            = [tex]\sqrt{11-4x}-1+x^2[/tex]

(g - f)(-1) = [tex]\sqrt{11-4(-1)}-1+(-1)^2[/tex]

             = [tex]\sqrt{15}[/tex]

(g . f)(x) = g(x) × f(x)

            = [tex](\sqrt{11-4x})(1-x^2)[/tex]

(g . f)(2) = [tex](\sqrt{11-4(2)})(1-(2)^2)[/tex]

             = [tex]\sqrt{3}(-3)[/tex]

Answer:

  ∠B = ∠C = 138°

  ∠D = 42°

Step-by-step explanation:

Angles between the parallel bases are supplementary:

  ∠B = 180° -∠A = 180° -42° = 138°

Right-side angles are the same measure as their mirrors across the line of symmetry.

  ∠C = ∠B = 138°

  ∠D = ∠A = 42°

Answer:

0.9115

Step-by-step explanation:

Using a binomial probability function :

P(x =x) = nCx * p^x * (1 - p)^(n - r)

Probability of success, p = 0.55

1 - p = 1 - 0.55 = 0.45

n = 8

x = 2

P(x > 2 ) = p(x = 3) + p(x = 4) + p(x = 5) + p(x = 6) + p(x = 7) + p(x =8)

To save computation time, we could use the binomial probability calculator :

P(x > 2 ) = 0.9115

Because we know what x is, we plug in 7 to the expression.

7+3<9

Since 7+3 is 10, then the new expression is 10<9.

I have no idea if this is a true/false question, because this statement is false.

Quick question, did you find the answer?

Answer:

4 is the BASE and 5 is the EXPONENT

Step-by-step explanation:

Thx i needed this answer :P

The number 5 is the exponent or power and the number 4 is the base of the expression.

Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.

The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.

The exponential expression is given as,

⇒ (4)⁵

In the exponential expression aⁿ, the n is the exponent or power and a is the base of the expression.

Then in the exponential expression (4)⁵, the number 5 is the exponent or power and the number 4 is the base of the expression.
