0.10x - 0.08x = 250 - 185
0.02x = 65
x = 3250
You can first use the fundamental trigonometric identity:
sin(x) ^2 + cos(x) ^2 = 1
=> cos(x) ^2 = 1 - sin(x) ^2
=> cos(x) ^2 = 1 - (-4/5)^2 = 1 - 16/25 = (25 - 16) / 25 = 9 /25
=> cos (x) = +/ - √ (9/25) = +/- 3/5
Now, analyze the sign.
In the fhird quadrant the cosine is negative, so the answer is cos(x) = - 3/5.
Answer: option C. - 3/5
Answer
Yes. The result both gives -1.
Step-by-step explanation:
The expressions are and
If he substituted g=0 and h=1
The result both gives -1.
Hello,
Here is your answer:
The proper answer to this question is: N=18
Here is how:
First writer the equation:
18=N-18
Now add 18 on both sides:
18+18=36
36=N
36÷2=18
Which means n=18!
N=18!
