I conclude that the sum will be even because any even number can be represented by 2n where n is a whole number
and even numbers are 2 apart, so
the sum of the first 15 are
2n+2(n+1)+2(n+2) etc until we get to 2(n+14)
we can undistribute the 2 from all of them and get
2(n+n+1+n+2...n+14)
and we are sure that whatever is in the parenthasees is a whole number because whole+whole=whole
therefor, the sum is even
if you did want to find the sum then
an=2n
the 15th even number is 30
the first is 2
S15=15(2+30)/2=15(32)/2=15(16)=240
which is even
Answer:
No
Step-by-step explanation:
-0.48 at the end should go first and 0.47 should be all the way on the right.
The answer is d.
The easiest way is to find a point within the shaded region and test out the equation.
Answer:
See explanation below.
Step-by-step explanation:
Assuming the following function:

Where y represent the sales and t the years after a particular model is introduced.
For this case if we find the domain for this function we have this:
Since the neatural log for negative numbers or 0 is not defined.
So then 
And the range on this case is all the possible reals.
The sales are equal to 0 when:

If we exponential both sides we got:


So then the x intercept is
. We don't have y intercept since the function not touch the y axis.
And we don't have a relative maximum or minimum since the function is increasing over the interval of all the reals.
The plot of the function is on the figure attached.
Answer:
579 pastries
Step-by-step explanation:
You can write an equation to solve this problem.
(3 * 147) + 138
(441) + 138 = 579
They sold 579 pastries in total.
