2xy, -xy, and 1/2xy because they contain the same variables
X = 0, for starters. Also, X + Y = Y( true for any Y value when X = 0)
Answer:
Step-by-step explanation:
the is answer is 2 3root2
like 2 on the outside, 3 as the small number, and 2 as the big number in the symbol
The given curve is y = 5x -4, -1 ≤ x ≤ 3.
The length of the arc is computed from the formula

The derivative is
y' = 5
Therefore

Note that
x = -1 +> y = 5(-1) - 4 = -9
x = 3 => y = 5(3) - 4 = 11
The distance between the points (-1, -9) and (3, 11) from the distance formula is
D = √[(3-(-1))² + (11-(-9))²] = √(16+400) = 20.396
This answer agrees with that obtained by integration.
Answer: 20.396
Obtained by integration and verified by the distance formula.
