Answer:
The differential equation is 
Step-by-step explanation:
Differential equation for the rate of change in radiation level:
Radiation level is R.
Rate of change indicates that the radiation level R varies in function of time t, which mathematically means that we have:
After the reactor is shut down, the radiation from the nitrogen-17 decreases in such a way that the rate of change in the radiation level is directly proportional to the radiation level.
Rate of change is k. Decreases means that k is negative. Proportional to the radiation level of R means that -k multiplies R. So the differential equation is:
The associative property allows you to change the <em>grouping</em> of addends or factors without changing the value of the expression.
Answer:F(x) is a negative number with a small absolute value
Step-by-step explanation:
-9/ 3= -3
-3 + -4 + -2 = -9
the numbers are -2 , -3 , -4
Answer:
Step-by-step explanation:
Let p be the number of identical packages.
We have been given that each package has a mass of 37.4 kg, so weight of p packages will be 37.4p.
The total mass of Renna and her load of identical packages is 620 kg.
We have been given that the mass limit for the elevator is 450 kg. This means that Renna can remove p packages from 620 kg such that 620 minus weight of p packages will be less than or equal to 450 kg.
We can represent this information in an inequality as:
Therefore, the inequality can be used to determine the number of packages, p, Renna could remove from the elevator to meet the mass requirement.
