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
Because y varies inversely as x, therefore
where k = constant.
When x = 6, y = 2.5. Ther efore
Cross multiply.
k = 6 x 2.5 = 15
The equation is
When x = 4, obtain
Answer: a. 3.75
Answer:
equal
Step-by-step explanation:
A negative negative is positive
We are comparing +5 to +5
They are equal
+5 = +5
Answer:
the handle will end up on the left side
Step-by-step explanation:
The cup is rotated 180 degrees clockwise. Therefore, I assume the rotation is about the center of the bottom of the cup. Also, only the cup is rotated, not the saucer (although this makes no difference in this problem).
The result is that the handle will end up on the left side. The cup will still be right side up.
Answer:
2 acres/hour
Step-by-step explanation:
Please share the possible answer choices. Thank you.
If two points on this straight line graph are (3, 1.5) and (5, 2.5), then we can find the slope of this line as follows:
As we move right from x = 3 to x = 5, x (the "run") increases by 2 and y (the "rise") increases by 1. Thus, the slope of this line is m = rise / run = 2/1, or
m = 2.
area mowed
The units of measurement here are m = ----------------------
time spent
and so we could conclude that the rate is 2 acres per hour.
