Answer:
Step-by-step explanation: Given that
and
lies in Quadrant III.
We are to find the value of
We will be using the following trigonometric identities:
We have
Since lies in Quadrant III, so tangent will be positive.
Thus,

The equations above are all in the format 
, where 
= the gradient, or slope.
So, in the first question,
, the gradient would be 4, because 4 is in this equation (the number before the 
).
The gradient of a line perpendicular to this line is equal to the negative reciprocal of the gradient of the line. A better way to explain it is if = the gradient of the line and <u />
= the gradient of the perpendicular line then:
So in the first question, the gradient of the perpendicular line is
.
So, in the first question,
The gradient of a line perpendicular to this line is equal to the negative reciprocal of the gradient of the line. A better way to explain it is if

Answer:
0.397
Step-by-step explanation:
In the experiment, if the coin is flipped 4 times, the outcomes in which there is a single heads out of the 4 flips are:
HTTT,THTT,TTHT and TTTH
The probability of flipping a head, P(Head)=0.18
Therefore: The probability of flipping a tail, P(Tail)=1-0.18=0.82
We can then calculate the probability that there is a single heads out of the 4 flips
=P(HTTT)+P(THTT)+P(TTHT)+P(TTTH)
=(0.18 X 0.82 X 0.82 X 0.82) + (0.82 X 0.18 X 0.82 X 0.82) + (0.82 X 0.82 X 0.18 X 0.82 )+ (0.82 X 0.82 X 0.82 X 0.18)
