To find kilometers using latitude and longitude:
distlon = lon2 - lon1 = 133-161 = -23
distlat = lat2 - lat1 = 54-48 = 6
a = (sin(distlat/2))^2 + cos(lat1) * cos(lat2) * (sin(distlon/2))^2
a = (sin(6/2)^2 + cos(48)*cos(54)* sin(-23/2)^2
c = 2 * arctan2( sqroot(a), sqroot(1-a) )
d = R * c (where R is the radius of the Earth, 6373 km's)
d = 2052 km's
April 30th to May 22nd is 23 days.
23 days x 24 hours per day = 552 hours.
Rate of travel = 2052 / 552 = 3.717 km per hour ( round answer as needed.)
B . The set of all first elements of the function is the answer
Answer:
2/3
Step-by-step explanation:
you reduce the fraction to get the scale factor. so 8/12 reduces down to 2/3 which is the scale factor
Answer:
40
Step-by-step explanation:
f(4) = 3(4²) - 2(4)
= 3(16) - 8
= 48 - 8
= 40
when x=4, f(x) = 40
(x+4)²=-63
