Answer:
The expression that models the growth of users is:
The rate of change per quarter is 7.5%
Step-by-step explanation:
Since the number of users is growing at a rate of 30% per year, then initially we have 5400, but after the first year we will have:
After the second year we will have:
After the third year we will have:
This will continue as the years passes. Therefore:
The rate of change pre quarter of year is the rate of change pre year divided by 4,therefore:

(Pay attention to the subject you're choosing, this is supposed to be in the Chemistry section, not here in the Mathematics)
On the periodic table, the Magnesium Mg is located in period 3, group 2. So it got 12 electrons.
So to become the cation Mg2+, the Magnesium has lost 2 electrons during it's formation.
So 12-2=10.
So there's 10 electrons in the Cation magnesium Mg2+
Hope this Helps! :)
Answer:
nx^(n-1).
Step-by-step explanation:
d/dx (x^n)
We multiply by n than subtract 1 from the exponent (n):
= n x^(n-1)
Numerical examples:
d(x^3) dx = 3 * x^(3-1)
= 3x^2.
d(2x^5)/dx = 5*2 x^(5-1)
= 10x^4.
Answer:
yes
Step-by-step explanation:
both the lines are at the same spot on the graph (where they intersect) so that is the ordered pair.
