E. the zeros of the graph is at (0,0) and (12,0) and the function is negative,
moreover, the max is (4,81), which shows how the speed goes up then down.
f.
x=t
f(t)=t²
f(x)=x²
g. is more complicated.
Answer:
1/6
Step-by-step explanation:
Because there is only a side that has the number 4 in a total of 6 sides
Answer: C {3, 4}
Step-by-step explanation:
<em>Solve the inequality:</em>
7x + 6 > 20
7x > 20 - 6
7x > 14
x > 2
Only 3 and 4 are greater than 2.
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.
