Answer:
r₁ = 3.583cm
V₁= 192.55cm³
r₂= 5.176cm
V₂ = 580.283cm³
r₃ = 5.255cm
V₃ = 607.479cm³
Step-by-step explanation:
assuming circumferences of each balloons are given as follows C₁ = 22.5cm, C₂ = 32.5cm and C₃ = 33cm
Recall C = 2πr
volume of a sphere is 4/3πr³
Amplitude is 3
Horizantal Shift 3 units to the left
Vertical Shift of 2 units up
Domain is [-1,1]
Range is [-1,5]
We get an infinite number of solutions when we have equivalent equations, for example equations that a scalar multiples of each other. That's not going to happen for two equations in slope intercept form unless all the terms are the same. None of those on this list.
So we're left with the second choice, and clearly the second equation is three times the first, with the same solution set, all the points along the line.
Answer: Second choice y=-3x + 4 and 3y = -9x + 12
