The answer is A because if you plug in the coordinates (0,0) into y<x^2+2x+1 you get....0<1+2+1. Which simplified is 0<4. For the other equation if you plug in (0,0) you'd get 0≤-3 which is false.
Answer: #1 ). 84.8230016469 if using actual pi or 84.78 if using 3.14
#2). 113.04
Step-by-step explanation:
Answer: y = v₀tgθx - gx²/2v₀²cos²θ
a = v₀tgθ
b = -g/2v₀²cos²θ
Step-by-step explanation:
x = v₀ₓt
y = v₀y.t - g.t²/2
x = v₀.cosθt → t = x/v₀.cosθ
y = v₀y.t - g.t²/2
v₀y = v₀.senθ
y = v₀senθ.x/v₀cosθ - g/2.(x/v₀cosθ)²
y = v₀.tgθ.x - gx²/2v₀²cos²θ
a = v₀tgθ → constant because v₀ and θ do not change
b = - g/2v₀²cos²θ → constant because v₀, g and θ do not change
F(x) slope is bigger than g(x) as 6>2
G(x) because 6 is the slope of g(x) and -6 is the slope of f(x)
Reflection across y=x is a special case transformation

The original triangle has vertices A(-5,1), B(-4,3), C(-2,1), D(-3,-1) so the transformed triangle has vertices
A'(1,-5), B'(3,-4), C'(1,-2), D'(-1,-3)
Choice A'(1,-5)
