Answer:
x = π/4 and 5π/4
Step-by-step explanation:
Given the expression;
2cos²x - 1 = 0
2cos²x = 0+1
2cos²x = 1
cos²x = 1/2
cos x = ±√1/2
cos x = ±0.7071
x = arccos(±0.7071)
x = ±45 degrees
Convert to radians
Sence 180° = π rad
45° = x
x = 45π/180
x = π/4
If x = -45°
Since cos is negative in the 3rd quadrant
x = 180 + 45
x = 225°
x = 225π/180
x = 45π/36
x = 5π/4
Answer:
A. Negative information is given a relatively larger weight than positive information.
Step-by-step explanation:
Among the options enlisted, the fact that negative information is given a relatively larger weight than positive information, signposts the manner in which information is processed by an interviewer.
During the recruitment and/or interview processes, the recruiter is presented with a pool of candidates with varying skills and competencies. The scenario here will be that the recruiter will come up with penciled skills and character to;
1. Streamline and reduce the large number of applicants
2. Ensures that applicants are properly matched with the right jobs
To achieve the foregoing therefore, and considering the large pool of candidates, the interviewer will be highly sensitive to negative information that could pose a threat to the underlying recruitment objective.
Answer: Solve for Y
y = -16x - 38
And then y intercept is
(0, -38)
Step-by-step explanation:
If the expression is: yⁿ
then y is the Base.
If the expression is: yn
then y is the product.
