Answer:
No
Step-by-step explanation:
Two triangles are similar if their corresponding angles are congruent and the corresponding sides are in proportion They are the same shape, but not necessarily the same size
Triangle ABC 54 +68 + 58 = 180
Triangle EFG 68 +63 +49 = 180
In this case their corresponding angles are nor congruent
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>
Yes it’s a regular polygon I Think
Wat is help sheet, didn't help,
instructions unclear, got my calculator stuck in the ceiling fan
remember some simple exponential laws
and
first one
2nd one
third one
dunno wat to do with 'help sheet'
