Answer: x is 52 and y is 38.
Step-by-step explanation:
x+128=180
x=52
52+y=90
y=38
I believe the answer is 8
True because rational numbers are countable, but the irrational numbers are uncountable.
Answer:
Faction of population = 1.39 / 7.2
Percentage of population = 19.3% (Approx.)
Step-by-step explanation:
Given:
China's population in 2014 = 1.39 billion (Approximately)
Find:
Compare China's population to world population
Computation:
World's population in 2014 = 7.2 billion (Approximately)
Faction of population = China's population in 2014 / World's population in 2014
Faction of population = 1.39 / 7.2
Percentage of population = [China's population in 2014 / World's population in 2014]100
Percentage of population = [1.39/7.2]100
Percentage of population = [0.193]100
Percentage of population = 19.3% (Approx.)
Answer:
Steps below
Step-by-step explanation:
8) x = y²/2 2rcosΘ = r²sin²Θ 2cosΘ = rsin²Θ
r = 2cosΘ/sin²Θ = 2cotΘcscΘ
9) (x+2)²+y²=4 y= rsinΘ x=rcosΘ
(rcosΘ+2)²+y²sin²Θ = 4
r²cos²Θ+4rcosΘ+4+y²sin²Θ=4
r²(sin²Θ+cos²Θ)+4rcosΘ=0
r²+4rcosΘ=0 r+4cosΘ=0
r = - 4cosΘ
10) r = 2sinΘ r=2* y/r r²=2y x²+y²=2y
x² + (y²-2y+4) = 4 x²+(y-2)² = 4
11) r = 3tanΘsecΘ = 3* (y/x) * (r/x)
1 =3y/x²
x² = 3y 3y = x²
