Answer:
2
Step-by-step explanation:
g(9)=2 since g(x)=2
Answer:
The circumference is pi times larger than the diameter of a circle.
Step-by-step explanation:
The formula of the circumference of a circle is
C = 2(pi)r = (pi)d
C = (pi)d
To find the ratio of the circumference to the diameter, divide both sides of the equation by d.
C/d = pi
The circumference is pi times larger than the diameter of a circle.
Hello! To answer this question, all you have to do is subtract both numbers from each other. 14.6 - 5.2 is 9.4. The numbers are 9.4 units away from each other on a number line. An expression that would represent a distance between them are 14.6 - 5.2 = x. Just make the negative numbers positive to make it easier to solve.
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]
