i know a triangular prism has 5 faces and six vertices if that helps
After 1 hour, 360 g decays to 180 g.
After another hour (total 2 hours), 180 g decays to 90 g.
After another hour (total 3), 90 g decays to 45 g.
After one more (total 4), 45 g decays to 22.5 g.
More quickly, with a half-life of 1 hour, the 360 g of starting material decays to
(360 g) / 2⁴ = 22.5 g
In general, if the half-life is 1 hour, then after <em>n</em> hours, an initial amount <em>A</em> of this substance decays according to
<em>A</em> / 2<em>ⁿ</em>
204 is 10.2% of 2000
Working Out
204/2000 x 100 = 10.2%
Since is a positive a value (4) we know that the graph opens upward. -5 represents how far up or down the “vertex” is of the absolute value graph. This means that the range is -5
Answer:
12
units^3
Step-by-step explanation:
V=1/3Bh
=1/3 Area of the base times height
Area of base: r^2=4
height=9
4 times 9=36
1/3 of 36 =12
