Answer:
Sure here O- cookie
Step-by-step explanation:
I believe the correct answer from the choices listed above is option A. <span>In right triangle LMN, L and M are complementary angles and sin(L) is 19/20. Therefore, cosine of M would be 19/20 as well. It would be helpful if you draw a figure of the problem. Hope this answers the question.</span>
Answer:

Step-by-step explanation:
Given

Required
Write, using scientific notation
The scientific notation is written in the form:
<em>Where n is an integer and </em>
<em />
To start with; <em>Represent the given number as fraction</em>

Represent the denominator as an exponent

This can be rewritten in form of:

Remember that:
<em>Where n is an integer and </em>
<em />
<em>This implies that; we need to adjust 2711 to a number between 1 and 10;</em>
This gives:

Write 1000 as an exponent

Apply law of indices


The question requires 2 numbers after the decimal point;
So, 2.711 will be approximated to 2.71

Hence;
<em></em>
<em> </em><em>is equivalent to </em>
<em></em>
