Answer: 286 and 1/3

Step-by-step explanation: 3 goes into 859 286 times without any remainder. (3 x 286 = 858)

858 and 859 are 1 apart, and 1 is 1/3 or 3. This means the answer is 286 and 1/3

Answer:

C. a=12ft, b=12ft

A book falls from a shelf that is 5 feet above the floor. A model for the height h in feet if an object dropped from an initial

Brums [2.3K]

Answer:

About 0.559 seconds

Step-by-step explanation:

The height equation is:

$h=-16t^2+h_0$

Where $h_0$ is the initial height of the book, which is 5, so we can write:

$h=-16t^2+5$

Now, we want time it took for the book to reach ground (h = 0)

So, we substitute h = 0 and solve for t:

$h=-16t^2+5\\0=-16t^2+5\\16t^2=5\\t^2=0.3125\\t=0.5590\\t=0.559$

It took about 0.559 seconds for the book to reach the ground
