Answer:
The answer to your question is: Incorrect
Step-by-step explanation:
Sid is wrong because 26 is not a multiple of 3.
A number is multiple of three if the sum of its digits is multiple of three.
Example:
24 = 2 + 4 = 6 6 is a multiple of 3
27 = 2 + 7 = 9 9 is multiple of 3
but 26 = 2 + 6 = 8 8 is not a multiple of 3
Answer:
Step-by-step explanation:
Let the function be:
f(x, y) = 2(y^2) - x^2 = 8
Since the shortest distance is basically a straight line from point (3, 0) to
f(3, y).
2y^2 - 3^2 = 8
2y^2 = 17
y = sqrt(17/2)
So the nearest point on the planes course to the point (3,0) is (3, sqrt(17/2))
Now lets use the distance formula:
x1 = 3
y1 = 0
x2 = 3
y2 = sqrt(17/2)
![=\sqrt{\left(3-3\right)^2+\left(\sqrt{\frac{17}{2}}-0\right)^2}](https://tex.z-dn.net/?f=%3D%5Csqrt%7B%5Cleft%283-3%5Cright%29%5E2%2B%5Cleft%28%5Csqrt%7B%5Cfrac%7B17%7D%7B2%7D%7D-0%5Cright%29%5E2%7D)
![=\sqrt{(0)^2+(\sqrt{\frac{17}{2}})^2}](https://tex.z-dn.net/?f=%3D%5Csqrt%7B%280%29%5E2%2B%28%5Csqrt%7B%5Cfrac%7B17%7D%7B2%7D%7D%29%5E2%7D)
![=\sqrt{(\sqrt{\frac{17}{2}})^2}](https://tex.z-dn.net/?f=%3D%5Csqrt%7B%28%5Csqrt%7B%5Cfrac%7B17%7D%7B2%7D%7D%29%5E2%7D)
![=\sqrt{\frac{17}{2} }](https://tex.z-dn.net/?f=%3D%5Csqrt%7B%5Cfrac%7B17%7D%7B2%7D%20%7D)
So m in this case is just 17/2 and the square root of m is sqrt(17/2) = 2.91547594742
Circumference of the entire circle = 2 * PI * radius
circumference = 2 * PI * radius
circumference =

62.832
81 degrees is (81 / 360) or .225 of the entire circumference
so the 81 degree arc = .225 * 62.832 = 14.137 feet
