Can a pentagon be a cross section of a triangular prism?
nikitadnepr [17]

Answer:

<em>No</em>, a pentagon can NOT be a cross-section of a triangular prism.

Step-by-step explanation:

Prisms have a uniform cross-section and are named after their cross-section. Hence, the cross section of a triangular prism is a triangle. The only prism with a pentagon cross-section is a pentagonal prism.

a 23 gram sample of a substance thats a by-product of fireworks has a K-value of .13. whats the substances half life in days
nata0808 [166]
Given:
Initial mass, m₀ = 23 g
Decay constant, k = 0.13

Exponential decay obeys the equation
m(t)=m_{0} e^{-kt}
where t = time, days

For half life, the mass is m = m₀/2.
Therefore
e^{-0.13t} = \frac{1}{2} \\ -0.13t = ln(0.5)\\t= \frac{ln(0.5)}{-0.13} =5.33

Answer: The half life is 5.33 days
