Actually none of the answers is correct - it's neither 30,900 nor 40,000.
30,944 rounded to the nearest ten thousand will give us 30,000. It's because 30,944 is closer to 30,000 than to 40,000.
Answer:
A) Θ = 2A/r²
Step-by-step explanation:
A = Θr²/2
(Multiple both sides by 2)
2A = Θr²
(Divide both sides by r²)
2A/r² = Θ
y=-4x+7
the -4 is the slope and the 7 is the y-intercept
1. Replace f(x) with y: y = 3x - 15
2. Interchange x and y: x = 3y - 15
3. Solve this for y: 3y = x + 15, and y = (x + 15)/3
4. Replace y with
-1 -1
f (x): f (x) = (x + 15) / 3 (answer)
