Answer:
495.62
Step-by-step explanation:
Given data
Amount=$17,886
Rate = 11%
TIme= 11 years
Let us apply the compounding expression
A=P(1-r)^t----------The negative sign is due to decreasing value
substitute
A= 1786(1-0.11)^11
A=1786(0.89)^11
A=1786*0.2775
A=495.615
Hence the approximate Amount will be 495.62
The cost function is
c = 0.000015x² - 0.03x + 35
where x = number of tires.
To find the value of x that minimizes cost, the derivative of c with respect to x should be zero. Therefore
0.000015*2x - 0.03 = 0
0.00003x = 0.03
x = 1000
Note:
The second derivative of c with respect to x is positive (= 0.00003), so the value for x will yield the minimum value.
The minimum cost is
Cmin = 0.000015*1000² - 0.03*1000 + 35
= 20
Answer:
Number of tires = 1000
Minimum cost = 20
Answer: 8(x + (-5)) = 2x
Step-by-step explanation: Lets have that "certain" number be x. We wrote an equation to represent the problem.
