Answer:
The watered area is approximately 3783 square feet.
Step-by-step explanation:
The area that is watered due to the rotation of the spankler is a circular section area (), whose formula is:
Where:
- Water distance, measured in feet.
- Rotation angle, measured in sexagesimal degrees.
Given that and , the watered area is:
The watered area is approximately 3783 square feet.
Answer:
(1/2, 0), (0, -2)
Step-by-step explanation:
We can determine the slope from ...
slope = (change in y)/(change in x) = (10 -2)/(3 -1) = 8/2 = 4
Then an equation for the line can be written for slope m and point (h, k) as ...
m(x -h) -(y -k) = 0
Using the slope we calculated and the first point, we have the equation ...
4(x -1) -(y -2) = 0
4x -4 -y +2 = 0 . . . . . eliminate parentheses
4x -y = 2 . . . . . . . . . . put in standard form
Now, we can divide by the constant on the right to put this into intercept form:
x/(x-intercept) + y/(y-intercept) = 1
x/(1/2) + y/(-2) = 1
The x-intercept is 1/2; the y-intercept is -2.
Answer:
c.) π/4
Step-by-step explanation:
Form the desired ratio and simplify:
A / B = circle area / square area
= (36π)/(144) = (π·36)/(4·36) = π/4 . . . . matches choice C
Answer:
8
Step-by-step explanation:
The outlier is the puece of data that is very different from the rest. If all of the numbers in this data were to be put on some sort of visualization, most of the numbers would be in a clump, while the 8 would be far from the clump.
