SCORPION-xisa [38]3 years ago
7 0

Answer:

a=15849*a_{o}

Step-by-step explanation:

The Richter scale is a logarithmic scale

\log_{10}\left( \frac{a}{a_{o}} \right)=4.9\\\left( \frac{a}{a_{o}} \right)=10^{4.9}\\\left( \frac{a}{a_{o}} \right)=10^{4.9}\\\left( \frac{a}{a_{o}} \right)=15,849\\{a}=15,849*{a_{o}}

According to internal revenue records 1.65 of all household tax returns are audited.according to humane society 38% of all house
Paul [167]

Answer:

0.627%

Step-by-step explanation:

Probability calculates the likelihood of an event occurring. The likelihood of the event occurring lies between 0 and 1. It is zero if the event does not occur and 1 if the event occurs.

For example, the probability that it would rain on Friday is between o and 1. If it rains, a value of one is attached to the event. If it doesn't a value of zero is attached to the event.

Probability of a randomly selected household to be audited and owns a dog = P(A ∩ B) = P(A) x P(B)

where A = household tax returns audited

B = percentage of households that own dogs

0.0165 x 0.38 = 0.627%

Identify the TRUE statement relating to a property of the function y = sin x
svlad2 [7]

The true statement relating to a property of the function y =sin x is that the maximum and minimum values of the function are 1 and -1 respectively. Option B

<h3>Properties of the function</h3>

The following are the properties of the sin trigonometric ratio of the function;

  • The sine graph rises till +1 and then falls back till -1 from where it rises again.
  • The function y = sin x is an odd function
  • The domain of y = sin x is the set of all real numbers
  • The range of sine function is the closed interval [-1, 1]
  • The amplitude of the function is half its range value
  • One cycle of the function is 6. 28

From the above listed deductions, we can see that the true statement about the function y = sin x is that the range which is always known as the maximum and minimum values of the function are 1 and - 1 respectively.

Thus, the true statement relating to a property of the function y =sin x is that the maximum and minimum values of the function are 1 and -1 respectively. Option B

5(wx-v)=9(x+v)<br> make x the subject
Zepler [3.9K]
Expand the brackets first
5(wx-v) = 9(x + v) 
5wx - 5v = 9x + 9v

Get all x's on one side and everything on on the other side
9x - 5wx = 9v + 5v

factorise out the x
x(9-5w) = 14v

then divide by 9-5w
x = 14v/(9-5w)

Find the measures of the complementary angles that satisfy each case. One of the angles is 3 times larger than the other.
Nookie1986 [14]

Answer:

22.5° and 67.5°

Step-by-step explanation:

The sum of complementary angles equal 90°.

Given that one of the complementary angles is 3 times larger than the other, let "x" represent the other angle.

Thus, the following expression can be written to represent this case:

x + 3x = 90

Solve for x

4x = 90

Divide both sides by 4

\frac{4x}{4} = \frac{90}{4}

x = 22.5

The measure of the complementary angles are:

x = 22.5°

3x = 3(22.5) = 67.5°
