Answer:
degrees apart in latitude: 91.22
degrees apart in longitude: 147.95
Step-by-step explanation:
Liverpool and Melbourne are two cities that are located very far away from each other. Liverpool is located in the northwestern part of England, while Melbourne is located in the southeastern part of Australia, so understandably their latitudes and longitudes are very different. In order to get to the distance in degrees between these two cities in latitude and longitude, we just simply need to sum the degrees of both of them and we will get to the result. The reason why simple summing will do the job is because they are on separate hemispheres, with Liverpool being on the Northern and Western Hemisphere, while Melbourne being on the Southern and Western Hemisphere.
Latitude distance:
53.41 + 37.81 = 91.22
Longitude distance:
2.99 + 144.96 = 147.95
Answer:
9-4i²
Step-by-step explanation:
(3-2i)(3+2i)
Use the FOIL method for this.
First: 9
Outer: 6i
Inner: -6i
Last: -4i²
9+6i-6i-4i²=
9-4i²
Answer:
< ABC = 80
Step-by-step explanation:
Inscribed Angle = 1/2 Intercepted Arc
< ABC = 1/2 ( 160)
< ABC = 80
Answer:
(7, -4.5)
Step-by-step explanation:
25−x=−4y ---> x=25+4y
3x−2y=30
use x to substitute into the second equation
3 (25+4y)-2y = 30
75+12y-2y=30
75+10y=30
10y=-45
y=-4.5
3x-2(-4.5)=30
3x+9=30
3x=21
x=7
check:
25-7=-4*-4.5
18=18 (yes)
3*7-2*-4.5=30
21+9=30
30=30 (yes)
