Answer:

-\sqrt{3} /2

Step-by-step explanation:

Note that this looks like the identity:

cos(A + B) = cosAcosB - sinAsinB.

In this case, A = π/12 and B = 3π/4. So, we can say that the given equation:

cos(π/12)cos(3π/4) - sin(π/12)sin(3π/4) = cos(π/12 + 3π/4) = cos(π/12 + 9π/12) = cos(10π/12) = cos(5π/6)

Ah, now we have a trigonometry problem we can easily solve!

cos(5π/6) = -cos(π/6) = -(√3)/2

Hope this helps!

KMN = 90° (tangent perpendicular to radius)

Using Pythagoras Theorem,

√(8^2 + 6^2) = √(100) = 10

Therefore KN = 10km

Consider this three-digit sequence: 943. Is the first digit the largest or the second digit the smallest, AND, is the third digi
wolverine [178]
The sequence: 9, 4, 3

The largest number in this sequence is 9.
This is because 9 is of greatest value, being farther from 0 than the numbers 3 and 4.

The smallest number in this sequence is 3.
This is because 3 is of least value, being closer to 0 than the numbers 4 and 9.

Knowing this, we can answer the first question- "Is the first digit the largest or the second digit the smallest?"

9 is the first digit in this sequence, and it is the largest.
4 is the second digit in this sequence, and it is not the smallest. 3 is the smallest value in the sequence, but it is not the second digit.

This means that "the first digit is the largest" is the correct answer to the first question.

Even numbers result in integers, numbers without decimals/fractions, when divided by 2.

3 is an odd number, since it does not result in an integer when divided by 2.
3 is the third number in this sequence.

9 is also an odd number for the same reason.
9 is the first number in this sequence.

Knowing this, we can answer the second question- "Is the third digit even or the first digit odd?"

3 is the third digit in the sequence, and it is odd, not even.

9 is the first digit in the sequence, and it is odd.

This means that "the first digit is odd" is the correct answer to the second question.

Answers:
1) The first digit, 9, is the largest digit in the sequence.
2) The first digit, 9, is odd.

Hope this helps!
