To find the critical number of that function we have to find the derivative and set it equal to 0 and solve for x. The derivative of the function is f'(x)=-10x+2. If we set it equal to 0 and solve, we have x = -2/-10 which simplifies to x = 1/5.
Answer:
x=-1
Step-by-step explanation:
By adding the bottom lines you can get
2x+11 = x+10
Simplifying this gets you
x=-1
The formula in getting the arithmetic sequence:
an = a1<span> + (n – 1)d.
</span>
We can substitute the values in order for us to know how many terms the sequence has.
an = 7373
a1 = 1313
d = 303
an = a1<span> + (n – 1)d
</span>7373 = 1313 + (n-1) 303
7373 = 1313 + 303n - 303
-303n = 1313 - 303 - 7373
303n = -1313 + 303 + 7373
303n = 6363
n = 21
So, there are 21 terms in the sequence given.
