1. X=3, 2. X=4, 3. X= 95/2
4% is not equivalent to 40%
0.4 is equivalent to 40%. Just move the decimal two places to the right.
2/5 is equivalent to 0.4, which in turn is equivalent to 40%. 2 divided by 5=0.4
The answers are all but 4%
The value of the cosine of angle
is 1.
Given a point
that is a terminal arm of an angle
in standard position, by trigonometric relations we have the following expression for the cosine:
(1)
Where:
- Angle measure, in sexagesimal degrees.
- Horizontal position of the point of the terminal arm, no unit.
- Vertical position of the point of the terminal arm, no unit.
If we know that
and
, then the cosine of the angle
is:


The value of the cosine of angle
is 1.

Hello from MrBillDoesMath!
Answer:
w = 8, -2
Discussion:
The expression is undefined when the denominator is zero. So when does
w^2 - 6w - 16 = 0? Let's factor the expression. A little trial and error shows that 8 + (-2) = 6 (the coefficient of w) and 8 * (-2) = -16 (the constant value) so w^2 - 6w -1 6 = (w-8) (w- (-2)) and the expression equals zero when w = 8 or w = -2
Thank you,
MrB
