Evaluate the line integral, where C is the given curve. C sin(x) dx + cos(y) dy, where C consists of the top half of the circle
kenny6666 [7]

Parameterize the circular part of C (call it C_1) by

x=4\cos t

y=4\sin t

wih 0\le t\le\pi, and the linear part (call it C_2) by

x=-4-t

y=4t

with 0\le t\le1.

Then

\displaystyle\int_C\sin x\,\mathrm dx+\cos y\,\mathrm dy=\left\{\int_{C_1}+\int_{C_2}\right\}\sin x\,\mathrm dx+\cos y\,\mathrm dy

=\displaystyle\int_0^\pi(-4\sin t\sin(4\cos t)+4\cos t\cos(4\sin t))\,\mathrm dt+\int_0^1(-\sin(-4-t)+\cos4t)\,\mathrm dt

=0+\displaystyle\int_0^1(\sin(t+4)+\cos4t)\,\mathrm dt

=\cos4-\cos5+\dfrac{\sin4}4

These angles are adjacent which means they share a side and a vertex. Adjacent angles are also supplementary so the measure of the two angles add up to 180 degrees. Since angle 1 is 137 degrees, angle two is 43 degrees. I hope this explanation helps you.

The elevation of city A is 96 feet below sea level; the elevation of city C is 24 feet below sea level. The elevation of city D
dedylja [7]
We shall use a negative sign for an elevation below sea level, and a positive sign for an elevation above sea level.

Given:
Elevation of city A = -96 ft (below sea level)
Elevation of city C = -24 ft (below sea level)

Let x =  elevation of city D.

Part A.
Because the elevation of city D is 1/4 of the elevation of city C, therefore
x = (1/4)*(-24)

Part B.
Because 24/4 = 6, therefore
x  = -6 ft.

Answer:
The elevation of city D is 6 feet below sea level.
The answer is negative because the elevation is below sea level.

Can you help me in this question?
dezoksy [38]

Answer:

C

Step-by-step explanation:

2m + 3m = 5m

9m - 5m = 4m

11m - 6m = 5m

Therefore, the expression 11m - 6m is equivalent to 2m + 3m

(as they both equal 5m)
