a. Write and simplify the integral that gives the arc length of the following curve on the given integral. b If necessary, use t
WINSTONCH [101]

Answer:

\int\limits^{\pi/2} _0 (1+4cos^{2} (2x)dx

Step-by-step explanation:

Arc length is calculated by dividing the arcs in to small segments ds

By pythagoren theorem

ds^2=dx^2+dy^2

then integrate ds to get arc length.

We are given a function as

y = sin 2x in the interval  [0, pi/2]

To find arc length in the interval

Arc length s =\int\limits^{\pi/2} _0 {1+y'^2} \, dx \\=\int\limits^{\pi/2} _0 (1+4cos^{2} (2x) )dx

Hence arc length would be

B) \int\limits^{\pi/2} _0 (1+4cos^{2} (2x)dx

Can someone help me with questions 25 through 28
AleksAgata [21]
25. 3y+15

26. 15k+20

27. 21n+7p

28. 60w+20x

Also, you got number 19, number 21, and number 24 wrong.

D+D+D+D+D = 5D, not D⁵

S+S+S = 3S, not S³

N+N+N+N = 4N, not N⁴

Remember, repeated addition, (n+n+n) is 3n. Repeated multiplication, (n•n•n) is n³.

Hope this helps.

Line passes through (-5,3) and (-6,-1). Line B passes through (3,-2) and (2,-7). Are the lines parallel? Explain.
FromTheMoon [43]

Answer:

No they are not parallel.  

Step-by-step explanation:

You have to figure out the slopes of each set of points. For  (-5,3) and (-6,-1) the slope is 4 and for  (3,-2) and (2,-7) the slope is 5. You can only have parallel lines if the slope is same and the y- ints are different. Here the slopes aren't same.

Sorry If im wrong. Hope this helps!
