Answer:
And solving for x we got:
And taking square root we got:
Step-by-step explanation:
For this case we have the following point given 
And we want to find the value of x, since P lies on the unitray circle if we find the distance from P to the center of the unitary circle (0,0) we need to get 1. Using the definition of Euclidean distance that means:
And if we square both sides of the last equation we got:
And solving for x we got:
And taking square root we got:
A response variable you are trying to measure once you've done the experiment.
What have you done? You've measured what sunglasses will do to affect eyesight. You have used a 10 week period to measure their response. You don't really care what the response is -- only if there is one.
10 people and 10 weeks don't change. Those two are not a choice for an answer. Now you come to the crunch of the question. Is it the sunglasses you are trying to measure or is it what your eyes have done because you were wearing sun glasses.
So we need an answer. If you say sun glasses, how did you measure what they did. THAT's the answer. The answer is not the sunglasses.

The answer to A. is 108cm or 1.08m
First convert 2m to cm:
2m x 100 = 200 cm
Next convert 6m to cm:
6m x 100 = 600 cm
Divide the height of the person by his/her shadow:
200cm ÷ 600cm = <span>0.33333333333 = .3</span>
Multiply 360cm by .3:
360cm x .3 = 108cm
108cm ÷ 100 = 1.08m
The answer to B. is 6.8 cm.
The scale seems a bit small... are you sure you don't mean 0.8 m?
a = length of actual car.
8.5 x 0.8 = 1 x a
6.8 = 1 x a
6.8 ÷ 1 = a
6.8 = a
If you did mean 0.8 m... the answer is 680 cm or 6.8 m.
a = length of actual car.
0.8m x 100 = 80cm
8.5 x 80 = 1 x a
680 = 1 x a
680 ÷ 1 = a
680 = a
680 ÷ 100 = 6.8
