The cities of Singapore (in Asia) and Kigali (in Africa) both lie approximately on the equator. Singapore is at 104° longitude, and Kigali is at 30° longitude. If the earth is a sphere of radius 4000 miles, use arc length to find the distance between the cities. [Use π = 3.14, and round to the nearest mile.] A) 4880 miles B) 5160 miles C) 5410 miles D) 5650 miles

B) 5160 Miles

Step-by-step explanation: My explanation is that my answer is correct.

option 2 is correct.

step-by-step explanation:

we are given two inequality equation

x+y> 5 and -3x+2y< -2

first we draw the graph of both function using t-table method

equation: x+y> 5

for x=0, y=5

for x=-5, y=0

table:

x   :   0     5

y   :   5     0

test point (0,0) , 0> 5

false

equation: -3x+2y< -2

for x=0, y=-1

for x=2, y=4

table:

x   :   0     2

y   : -1       4

test point (0,0) , 0< -2

true

now we draw the graph. see the attachment for graph.

common region would be solution set.

option 2 is correct.
