Answer:
The answer would be (-7,3)
Step-by-step explanation:
Answer:
You can choose which equation below suits your taste but I recommend the 2n + 1 = -33.
Step-by-step explanation:
The line would intersect with the y-axis at (0,0)
1 gallon = 4 quarts.
15 quarts/ 4 = 3.75 gallons
1 hour = 60 minutes
3.75 gallons / 60 minutes = 0.625 gallons per minute.
Of the four x-coordinates to choose only 1/√(11) belongs can belong to the unit circle.
The other three x-coordinates are greater than 1, then they are out of the unit circle.
The unit circle formula is x^2 +y^2 = 1
Then to find the y-coordinate given the x-coordinate you can solve for y from that formula:
y^2 = 1 - x^2
y = (+/-)√(1-x^2)
Substitute the value of x
y = (+/-)√{1 - [1/√(11)]^2} = (+/-) √{(1 - 1/11} =(+/-) √ {(11 -1)/11 =(+/-)√(10/11) ≈ +/- 0.95
