The volume of a gas "V" varies inversely with the pressure "P" put on it. If the volume is 360cm³ under a pressure of 20 kgcm2

Sav [38]

Answer:

15 Kg cm²

Step-by-step explanation:

Given that V varies inversely with P then the equation relating them is

V = $\frac{k}{P}$ ← k is the constant of variation

To find k use the condition

V = 360, P = 20, then

360 = $\frac{k}{20}$ ( multiply both sides by 20 )

k = 7200

V = $\frac{7200}{P}$ ← equation of variation

When V = 480, then

480 = $\frac{7200}{P}$ ( multiply both sides by P )

480P = 7200 ( divide both sides by 480 )

P = 15

The ellipse with center C(2, -3), vertices V(-8,-3) and V2(12,-3), and foci F1(-4,-3) and F2(8,-3). 6.

attashe74 [19]

Answer:

(x-2)²/100 + (y+3)²/64 = 1

Step-by-step explanation:

C (2,-3): h=2 k=-3

semimajor axis (CV): a=12-2=10

center-foci: c=8-2=6

semi minor axis: b² = a²-c²= 100 - 36 = 64

equation: (x-h)²/a² + (y-k)²/b² = 1

(x-2)²/100 + (y+3)²/64 = 1
