Since 15 liters of water flow through a water pipe and enter a tank within 4.5 minutes, the same amount of water would flow through a similar pipe at the same time. Therefore, if two similar water pipes are used, the volume of water that would flow into the tank in 4.5 minutes is 15 × 2 = 30 liters
Therefore, the time it will take to pump 727.5 liters of water into a water tank using 2 similar water pipes is
So for the first year the deposits would amount to 40 * 12 = $480
Now since the interest rate is applied yearly we will assume that the interest rate will be applicable to the amount that is left after the first year of deposits
So that would be 889.98 - 480 = 409.98
409.98 * 14.99 % = 61.45
The new amount owed for the second year would be 409.98 + 61.45 = 471.43
So by the end of the second year the debt would of been wiped clean with $8.57 to spare.
f (x) = a(x - h)2 + k, where (h, k) is the vertex of the parabola. FYI: Different textbooks have different interpretations of the reference "standard form" of a quadratic function.
The standard form of a parabola is y=ax2++bx+c , where a≠0 . The vertex is the minimum or maximum point of a parabola. If a>0 , the vertex is the minimum point and the parabola opens upward. If a<0 , the vertex is the maximum point and the parabola opens downward.
