Answer:
1)
2)
So then the model would be given by:
Step-by-step explanation:
For this case we have the following differential equation:
We can do this using algebra:
Part 1
And now we can integrate both sides like this:
We can use the u substituton for the left part
We can multiply both sides by 4 and we got:
, where
and after integrate the left part we got:
And if we apply exponential on both sides we got:
Now we can replace u and we got:
where
And then finally we have:
Part 2
For this case we have the initial condition y(0) =5 and if we use it we got:
So then the model would be given by:
Answer:
Here, the given problem,
The total number of hours =
Now, the number of hours to make each invitation card =
Hence, the total number of invitations =
a. Scale the number line from 0 to 1,
In which each unit represents
By the number line,
b. By model,
Take a grid which shows 1 hour and each box of the grid represents 1/12th hour,
By the grid,
That is, the number of hours to make invitation = 9
c.
Answer:
Step-by-step explanation:
Answer:
975 feet.
Step-by-step explanation:
2/3 = 4/6
650/4 = 162.5
162.5 x 2= 325
650+325 = 975
Answer:
y=x^2+6
you need to add in the exponent
