Answer:
9. No
10. Yes
Step-by-step explanation:
The first one is not, since you have (3, 3) and (3, 9). In a function, each x maps to a single y.
The second one is since every x appears only once.
Answer:
Density = Mass / volume
Problem B mass = 87.5 g and volume = 5 cm^3
Density = 87.5 / 5 = 17.5
This value is too low to be platinum
Step-by-step explanation:
Answer:
b and c
Step-by-step explanation:
We are given that a population whose growth over a given time period can be described by the exponential model

Let initial population =
when time t=0

After integrating
We get ln N=rt +C
Where C is integration constant
When t=0 then N=

Substitute the value of C then we get





When r=0.1 then we get

Hence, the population increase not decrease.
When r= 0
Then we get


Hence, the population do not increase or decrease.
So, a population with r of 0 will have no births or deaths during the time period under consideration.
If we take a positive value of r then the population will increase exponentially .
Hence, option b and c are both correct.
