Correct Question: Find the simplified product: 
Answer:
Step-by-step explanation:
Based on the rules of radicals, since 
and 
has the same index (square root), therefore:
To simplify this, multiply their bases together, and add their exponents.
Simplify further
Slope m=(y2-y1)/(x2-x1)
(x1,y1)=(-5,0)
(x2,y2)=(0,19)
m=19-0/0-(-5)
m=19/5=3.8
Slope is 3.8
Good luck.
When you have so many, it is convenient to use a spreadsheet or other technology to repeat the tedious task. See the table for the average rate of change.

CORRECTED QUESTION:
Two cities have nearly the same north-south line of 110 degrees Upper W. The latitude of the first city is 23 degrees Upper N, and the latitude of the second city is 36 degrees N. Approximate the distance between the cities if the average radius of Earth is 6400 km.
ANSWER: 1452.11 km
Step-by-step explanation:
Since the two cities both lies on the Northern latitude of the sphere along the same longitude, we are going to subtract the angles the latitude that each city subtend at the equator.
36 - 23 = 13 degrees i.e the angles between the with two cities on a cross section the large circle formed by the longitude and its center.
Applying the formula for the length of an arc on a sector on the large circle
(∅/ 360) x 2πR
where, ∅ = is the angle between the two cities
R = radius of the Earth.
13/360 x 2 x π x 6400 = 1452.11 km
