Answer:
C. 8
Step-by-step explanation:
f(5) =1/4(2)^5
because x=5
f(5)=1/4(32)
because 2^5 is 2*2*2*2*2=32
f(5)=8
because 1/4*32 or 32/4 is 8
Hope this helped :) I haven't even learned f(x) in school yet haha. I'm in 8th grade, but I took extracurriculars for math and I'm on the math team. Ergo, I know it's right!
The degree of the polynomial is 9 ( not determined by the first number)
The degree of a polynomial is the highest exponent.
Here the highest exponent is 6 but since y is not a term on its own, you add the exponent of the term together.
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
Hope it helps if u dont understand ask me again
