Answer: 19
Step-by-step explanation: when two negative signs are next to eachother, you need to add the two numbers.
A=p (1+rt)
A future value ?
p Principle 900
R interest rate 0.06
T time 9/12
A=900×(1+0.06×(9÷12))
A=940.5
Answer:
C. dL/dt=k(100−L)
Step-by-step explanation:
The rate of change of the number of words memorized is proportional to the number of words left to be memorized.
The rate of change is dL/dt.
The rate is a constant k. Since the rate is proportional to the number of words left to be memorized, and the initial number of words is 100, k has to be multiplied by (100-L).
So the correct answer is:
C. dL/dt=k(100−L)
X= 3
Y=4
I used the substitution method
