The substance of 256 gm will be decayed into 1 gm in 800 years.
Step-by-step explanation:
Given,
The substance decays 75% in every 600 years.
Amount of substance = 256 gm
To find the the time the substance to decay to 1 gm.
Now,
75% decay in 600 years
1% decays in 600÷75 years
100% decays in ×100 years
= 800 years
Hence,
The substance of 256 gm will be decayed into 1 gm in 800 years.

The ball takes 1.5 seconds to reach its maximum height
The ball's maximum height is 44 feet
<em><u>Solution:</u></em>
Given that,
<em><u>The height in feet after t seconds is given by the function:</u></em>
Let us first find the derivative of h(t)
Differentiate the given function with respect to t
At the maximum height the derivative of the function needs to be 0
Thus the ball takes 1.5 seconds to reach its maximum height
<h3><u>Find the ball's maximum height:</u></h3>
Substitute t = 1.5 in given function
Thus ball's maximum height is 44 feet
