The <em><u>correct answer</u></em> is:
The order is -11x⁵y² + 7x³y³ - 3x²y + 4; and the degree is 6.
Explanation:
To order them by x, we look at the powers of x. In the original polynomial, the power of x in the first term is 3, the power of x in the second term is 0, the power of x in the third term is 5, and the power of x in the last term is 2. Arranging them, we want 5, 3, 2 and 0. This explains the order.
The second term of the ordered polynomial is 7x³y³. The degree is found by adding the exponents of the variables in the problem; this gives us 3+3 = 6.
If we consider it as a combination problem, then we could calculate the how many combinations are there if we pick up three nodes out of six nodes, and then we have:
And the answer should be 20
The area of a circle can be found using:
pi x r^2 (where r is the radius)
If the area of the circle is 255pi, then:
pi x r^2 = 255pi
Now we need to make r the subject:
r^2 = 255 (cancel the pi on both sides)
r = square root of 255
r = 15.96871942
Answer: 15.96871942 feet
Hope the answer helps :)
Answer:
b.) distance north or south of the equator
Step-by-step explanation:
Lines of latitude are horizontal lines parallel with the equator.
The equator is the central line of latitude, and latitude is measured north or south of the equator.
Answer: b.) distance north or south of the equator
