F(x)=(x^3+4x^2+7x-9) d(x)=(x+3)<br><br> divide using long division

Alchen [17]

The result is x^2 +x +4 -21/(x+3).

_____

Polynomial long division tends to be easier than numerical long division because the quotient term never needs adjustment. It is always the ratio of the highest degree terms of the dividend and divisor.

Water flows through a pipe at a rate of 8600 cubic meters per hour. Express this rate of flow in quarts per second. Round your a

Answer:

R = 2524 quarts/s

Step-by-step explanation:

Water flows through a pipe at a rate of 8600 cubic meters per hour.

We know that,

1 m³ = 1056.69 quarts

1 hour = 3600 s

Rate of flow of water = 8600 cubic meters per hour

$R=8600\ \dfrac{m^3}{h}\\\\=8600\times \dfrac{1056.69\ \text{quarts}}{3600\ s}\\\\=2524.311\ \text{quarts/s}$

R = 2524 quarts/s

So, the rate of flow of water is 2524 quarts/s.
