Answer:
Answer:1.5*10^9 years
Step-by-step explanation:
The half life of the substance is given i.e 4.5B years. You can change it into seconds by multiplying it with 365 and 86400.
The current no of particles is given 78.88% which will be equal to 78.88 if you assume the substance had 100 no of particle initially.
Determine the decay constant by dividing 0.69 by half life
use these values in the equation for the answer.
[ln and e are inverse functions to eachother]
If the budget is $200 and he have 15 members then we have divide the two. 200 / 15 = $13.33 per shorts. 15x =< $200. x represents 13.33. So the solution represents the coach may spend up to $13.33 per pair of shorts. If it was even 1 cent more than $13.33 than he wouldn't have enough.So he can spend up to $13.33 or less per pair of shorts.
The length of arc is 69.1 feet
<em><u>Solution:</u></em>
<em><u>The length of arc when angle given in degrees is given as:</u></em>
Where,
r is the radius
is the central angle in degrees
From given,
<em><u>Substituting the values we get,</u></em>
Thus the length of arc is 69.1 feet
This is the answer its easy just simplify the inequality
