ce from the y-axis to the same point.
1 answer:
Answer:
(2√5)/5
Explanation:
CHECK THE ATTACHMENT BELOW FOR DETAILED EXPLATION
From the question we can deduced that the vertical distance from the x-axis to a point on the perimeter of the circle is twice the horizontal distance, we can say that the y-coordinate, is twice of the horizontal, then let call the horizontal "y", the vertical would be 2y.
from the attachment the question on the unit circle is interpreted using a figure,then, hypotenuse was first calculated

We know for the problem that Arnold drove 400 miles during his business trip, and the cost of each mile is $0.50, so the total cost of the miles the company will reimburse is: 
$.
Part A. We now know that the total cost of the miles the company have to pay to Arnold is $200. We also know the company pays him $40 a day for food and lodging. So let
represent the number of days of Arnold's business trip:
where
is the amount the company will reimburse Arnold after days.
is the number of days.
Part B. We know that the amount the company will reimburse Arnold is $2600, so
. Lets replace that value in our equation and solve for to find the number of days:
The first thing we are going to do to solve our equation is subtract 200 to both sides using the subtraction property of equality:
Next, we are going to divide both sides of the equation by 40, using the <span>division property of equality,</span> to find the value of:
Finally, we can use the reflexive property of equality to get:
Part C. We can conclude that Arnold spend 60 days in his business trip.
