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
Answer:
Yes f is a function of x
Step-by-step explanation:
f(x) means fuctoin of x thats what it stands for.
and it has a constant ratio of 1/2. Hope this helps!!
mark me as brainliest
Equation: 50 is greater than or equal to 45 + .5(x)
x = amount of pictures you can send without going over your budget
subtract 45 from both sides. you are left with: 5 is greater than or equal to .5(x)
multiply both sides by 2. you are left with: 10 is greater than or equal to x
Answer: 10 is greater than or equal to x
