Hello!
The rule regarding the division of exponents states the following:
=
Insert any known values into the formula above:
=
Simplify the expression:
=
We have now proven that is equal to .I hope this helps!
Based on gas laws:
PV/T = Constant, P = Pressure, V = volume, T = Temperature (K)
Therefore,
P1V1/T1 = P2V2/T2
P1 = 10 psig
V1 = 10 in^3
T1 = 65°F = 291.483 K
P2 = ?
V2 = 1.5 in^3
T2 = 180°F = 355.372 K
Rearranging the equation,
P2 = P1V1T2/T1V2 = (10*10*355.372)/(291.483*1.5) = 81.279 psig
Answer:
D
Step-by-step explanation:
A is an arithmetic sequence in that is adds or subtracts the same amount.
B is also an arithmetic is that it takes the original 1000 and adds another 1000 for each year
C is a geometric sequence because it's losing 5× however many questions missed
D is the answer because it says it loses 10% every year, so it loses 10% of the previous year, not the beginning year.
that would be the circumference of the circle
= 2 pi r
= 2 * pi * 2
= 6.28 feet to 2 DP's.
Answer:
80 km/hr
Step-by-step explanation:
This is asking for speed.
Speed=Distance/Time
Speed=720/9
Speed=80 km/hr
