Answer:
Distance between Nauru and Galapagos islands = 11525 Km to the nearest Km
Step-by-step explanation:
The angle between the two Islands is given as X
X = (180 - 166.56) + (180 - 90.30)
X = 13.44° + 89.70°
X = 103.14
Distance between the islands = length of the arc with angle X subtended at the center of the earth of radius R.
Length of arc = (X/360) × 2πR
Where, R, radius of the earth = 6400 Km
Length of arc = (103.14/360) × 2π × 6400 Km
Length of arc = 11525.48 Km
Therefore, distance between Nauru and Galapagos islands = 11525 Km to the nearest Km
Answer:
h is directly proportional to B and inversely proportional to A
Step-by-step explanation:
Answer:
49
Step-by-step explanation:
substitute b = - 6 and c = 7 into the expression and evaluate
c - 7b = 7 - (7 × - 6) = 7 - (- 42) = 7 + 42 = 49
Answer:
116
2
real
irrational
Step-by-step explanation:
discriminant= b^2-4ac
a=1 b=8 c=-13
discriminant = 8^2 -4*(-13)=64+52=116
if discriminant>0 then we have two real solutions
since √116 is not an integer, solutions are irrational
