Which functions have a range of [tex]$\left\{y \in R \mid-\infty\ \textless \ y\ \textless \ \infty\right\}$[/tex] ?
[tex]$f(x)=-(x+1)^2-4$[/tex]
[tex]$f(x)=x^2+7 x-9$[/tex]
[tex]$f(x)=-4 x+11$[/tex]
[tex]$f(x)=2^{x+3}$[/tex]
[tex]$f(x)=\frac{2}{3} x-8$[/tex]
Answer (2)
x = v t x = a t 2 v t = a t 2 v = a t a = t v = 7.4 11.3 = 1.527 m / s 2
To catch its prey, the cheetah must maintain a constant acceleration of approximately 3.05 m/s². This is calculated by first determining the distance covered by the prey and applying the equations of motion for the cheetah starting from rest. Setting the distances equal allows us to solve for the required acceleration.
