Answer:
-56-56n
Step-by-step explanation:
That's not an equation so I can't solve it. They're nothing it equals to.
If you need to multiply, it's Distributive Property: -7*8+ -7*8n = -56-56n
Answer:
im pretty sure that it is B?
Step-by-step explanation:
Answer:
option C.
Step-by-step explanation:
we have
System A
---> first equation system A
----> second equation system A
Multiply the second equation by 4 both sides
Adds this equation to the first equation system A
----> first equation system B
----> second equation system B
so
The first equation of System B is obtained by adding the first equation of System A to 4 times the second equation of System A
The second equations are identical
therefore
They will have the same solution
Answer:
And that would be the approximately cost for 2013.
Step-by-step explanation:
For this case we need to define some notation first.
A= population , t= represent the years after 2003, C= constant for the exponential model.
The starting point t=0 correspond to the year of 2003.
On this case we are assuming the following exponential model:
The initial value on this case is for t=0 A(t=0)= 120 and if we replace we got this:
And then the model is:
Now we need to determine the value for C. Since we know that inflation increase 4% per year we have that after one year we have 1.04 times the value of the original value, and we have this equation:
And we got this:
Applying ln on both sides we got:
So then our model is given by:
For 2013 we have that t=10 since 2013-2003 = 10 after 2003, if we replace t=10 we got this:
And that would be the approximately cost for 2013.
