yarga [219]

Answer:

Assume that 1900km^2 is 1900.

If that happens, The equation of that will look like...

1900 - (1900 x 7.75% x 14)%.

1900 x 7.75% are 147.25.

and 147.25 x 14 are 2061.5.

so... there will be no forest after 14 years.(harsh)

1. A penny is dropped from the top of the empire state building. The function h(t) = -16t^2 +1250 describes the height of the pe

liubo4ka [24]

Answer: $8.83\ s$

Step-by-step explanation:

Given

Height of the dropped penny is given by

$h(t)=-16t^2+1250$

When penny hit the ground, $h(t)=0$

$\therefore -16t^2+1250=0\\\Rightarrow 16t^2=1250\\\\\Rightarrow t^2=\dfrac{1250}{16}\\\\\Rightarrow t=\sqrt{\dfrac{1250}{16}}\\\\\Rightarrow t=8.83\ s$

Thus, it takes 8.83 s to hit the ground.
