Answer:
k = 2.
Step-by-step explanation:
j = c/k where c is a constant.
When k = 3, j = 12 so
12 = c/3
c = 36.
So the relation is j = 36/k
When j = 18
18 = 36 / k
So 18k = 36
k = 2.
Answer:
See below.
Step-by-step explanation:
When x has a value between 0 and 90 the values of sin x ranges from 0, if x = 0 and 1 , if x = 90 degrees.
The cosine of x has the reverse value: cos x is 1 for x = 0 and 0 for x = 90 degrees.
At x = 45 the sine and cosine are equal in value.
So for sin x < cos x the value of x must be between 0 and 45 degrees.
So a possible value of x is 30 degrees.
When x = 30 sin x = 0.5 and cos x = 0.866.
Answer:
It is the first and the last three.
