Answer:
The Number is 8.
Step-by-step explanation:
Let the number be x.
Given:
1/2 is subtracted from four times the reciprocal of a number, the result is 0.
Hence the equation will become like;
Now Solving the equation we get.
Now the we can see the number is 8, when 1/2 is subtracted from 4 times the reciprocal of number means 4/8 which becomes 1/2 and hence when 1/2 is subtracted from 1/2 it equals to 0.
Hence the number is 8.
Answer:
C
Step-by-step explanation:
Remember the mnemonic: SohCahToa, where:
Let's determine our side lengths first.
Note that our angle is A. So, we have to determine the sides with respect to A.
The opposite side to A is 16.
The adjacent side is 12.
And the hypotenuse is 20.
With this, we can find our trig ratios:
Sine:
Substitute 16 for the opposite and 20 for the hypotenuse. This yields:
Reduce:
Cosine:
Substitute 12 for the adjacent and 20 for the hypotenuse. This yields:
Reduce:
Tangent:
Substitute 16 for the opposite and 12 for the adjacent. This yields:
Reduce:
So, our answers are:
Out of the answer choices, the choice that represents this is C.
So, our correct answer is C.
And we're done!
