Answer:
a
Step-by-step explanation:
Answer:
(D) an = 5n - 1
Step-by-step explanation:
The sequence is generated by substituting a value for n.
The first term of the sequence is 4
So when n = 1
The formula is an = 5n - 1
a1 = 5(1) - 1
a1 = 5 - 1
a1 = 4
The second term of the sequence is 9.
So n = 2
a2 = 5(2) - 1
a2 = 10 - 1
a2 = 9
To find the next value you just have to substitute the next value for n.
To determine the maxima and minima of the polynomial, differentiate the given based on x and equate to 0.
C(x) = 400x - 0.2x²
dC(x) / dt = 400 - 0.4 x = 0
The value of x is 1000. This is the value of the maxima. As the value of C(x) continously becomes lesser as the value of x is set higher, the minima is not identified. Substitute x to the original equation,
C(x) = (400)(1000) - 0.2(1000²) = $ 200,000
Thus, the answer is letter B.
