I suppose the integral is
The integration region corresponds to a sector of a cirlce with radius 5 subtended by a central angle of π/4 rad. We can capture this region in polar coordinates by the set
Then , , and . So the integral becomes
Answer:
3/2
Step-by-step explanation:
Pick two points on the graph
(-1,2) and (3,8)
We can use the slope formula
m= ( y2-y1)/(x2-x1)
= ( 8-2)/(3 - -1)
= (8-2)/(3+1)
= 6/4
= 3/2
On a graph, go up 7 units and to the right 2 units from the origin
Answer:
II and III ( 2 and 3)
Step-by-step explanation:
The quadrants are numbered counter clockwise, with the top right being number I
