The an answer is 2x
explanation :
12+3x-x-12
= 3x-x
= 2x
x = 25.17/sin(40) x sin90
x = 39.16ft
39.16ft/sin90 = x/sin50
x = 30 ft
Answer:
avg rate of change = -2/3
Step-by-step explanation:
f(x) = -1/3(x-2)²+4
f(-4) - f(2) / [-4-(-2)]
= -8 - (-28/3) / -2
= (-24/3 + 28/3) / -2
= 4/3 · -1/2
= -4/6 or -2/3
800/10 = 80
80/10 = 8
8 x 10 = 80
80 x 10 = 800
one square represents 8
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
