4) secx/1 +cot²x

$\frac{sec \: x}{1 + cot { \: x}^{2} } = \frac{sec \: x}{cosec \: {x}^{2} } = \frac{ \frac{1}{cos \: x} }{ \frac{1}{sin \: x} } = \frac{sin \: x}{cos \: x} = tan \: x$

On the planet Jupiter, a ball this thrown upward at a velocity at 10m/s. It's height, h(t) meters after t seconds is given by th

Ilya [14]

Answer:

a) The maximum height that the ball reaches is 4 meters.

b) The height of the ball when it is released from thrower's hand is 2 meters.

c) The ball will take approximately 0.966 seconds to hit the surface of Jupiter.

Step-by-step explanation:

a) Let $h(t) = -12.5\cdot (t-0.4)^{2}+4$ , where $t$ and $h(t)$ are the time and height, measured in seconds and meters. Since this equation is in vertex form, the maximum height corresponds to the value associated with the dependent variable (height). That is:
