4x^6 / (2x - 6)
4x^6 / 2(x - 3)
2x^6 / (x - 3)
Answer:
C = StartFraction pi times 4 over 2 EndFraction.
Step-by-step explanation:
the circumference of a circle=
C= 2 times PI times radius
Radius= d/2
sooo it is
C = StartFraction pi times 4 over 2 EndFraction.
Answer:

Step-by-step explanation:
10/16/5=
KCF (Keep, change, flip)
10/16*1/5= 10/80
simplify
10/80=1/8
Answer:
Step-by-step explanation:
<u>Fractions</u>
We are given the expression:
We'll find an equivalent expression that results when simplifying the given fraction.
The numerator is a mixed fraction, which we'll convert into an improper fraction as follows:
Now it follows:
Instead of dividing fraction, we multiply by the reciprocal of the denominator:
Simplifying:
Answer:
434,470 gallons
Step-by-step explanation:
The exponential equation for the volume v remaining after t hours can be written as ...
v(t) = (initial amount)×(decay factor)^(t/(decay time))
v(t) = 500,000×(1 -10%)^(t/3)
Then after 4 hours, the remaining volume is ...
v(4) = 500,000×(0.90^(4/3)) ≈ 434,470 . . . . gallons

<em>Comment on the form of the equation</em>
The decay factor is related to the decay rate by ...
decay factor = 1 - (decay rate)
and the decay time is the time applicable to that decay rate. Here, the rate is 10% every 3 hours, so the decay time is 3 hours for a decay rate of 10%.
