Derive the equation and equate the derivative to zero.
dan/dt = -2n + 6 = 0
The value of n in the equation is 3. We substitute 3 to the original equation,
an = -(3)² + 6(3) - 7 = 2
The answer to this item is letter B.
Huh. Try be more specific and then I could help you out
Answer:
w= 9 3/4
Step-by-step explanation:
4 1/5 =21/5
13 19/20= 279/20
w+21/5 + 279/20
-21/5 -21/5
w+39/4
w=9 3/4

Answer:
Lizzie came up with a divisibility test for a certain number $m \neq 1$:
Break a positive integer n into two-digit chunks, starting from the ones place. (For example, the number 354764 would break into the two-digit chunks 64, 47, 35.
Find the alternating sum of these two-digit numbers, by adding the first number, subtracting the second, adding the third, and so on. (In our example, this alternating sum would be 64-47+35=52.
