Answer:
∫₂³ √(1 + 64y²) dy
Step-by-step explanation:
∫ₐᵇ f(y) dy is an integral with respect to y, so the limits of integration are going to be the y coordinates. a = 2 and b = 3.
Arc length ds is:
ds = √(1 + (dy/dx)²) dx
ds = √(1 + (dx/dy)²) dy
Since we want the integral to be in terms of dy, we need to use the second one.
ds = √(1 + (8y)²) dy
ds = √(1 + 64y²) dy
Therefore, the arc length is:
∫₂³ √(1 + 64y²) dy
Answer:
the length = eleven meters.
Step-by-step explanation:
area divided by width.
33/3 = 11.
Answer:
Step-by-step explanation:
hello :
(3+i)(2+i) = 6+3i+2i+i² but : i² = -1
(3+i)(2+i) = 5+5i
Which question do you need to be answered?
We may answer the question above by substituting the values of the coordinates of the points in the choices to the x and y of the inequality.
A. (-2, 4) 4 - 4(-2) ≤ -6 12 ≤ -6 FALSE
B. (1, -2) -2 - 4(1<span>) ≤ -6 -6 ≤ -6 TRUE
C (1, 3) 3</span> - 4(1<span>) ≤ -6 -1 ≤ -6 FALSE
D. (2, 3) 3</span> - 4(2<span>) ≤ -6 -5 ≤ -6 FALSE
The answer would be letter B. </span>
