the volume V of a gas at a constant temperature varies inversely with the pressure P. when the volume is 100 cubic inches the pr

fiasKO [112]

Answer:

The pressure is $20\ psi$

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent an inverse variation if it can be expressed in the form $y*x=k$ or $y=k/x$

In this problem we have

$V*P=k$

where

V is the volume of a gas at a constant temperature

P is the pressure

we have

For $V=100\ in^{3}$ , $P=25\ psi$

step 1

Find the value of k

substitute the values of V and P

$100*25=k$

$k=2,500$

The equation is equal to $V*P=2,500$

step 2

Find the pressure when the volume is 125 cubic inches

For $V=125\ in^{3}$

substitute in the equation and solve for P

$125*P=2,500$

$P=2,500/125=20\ psi$

Which graph represents the function f(x)=(x-5)^2+3

hammer [34]

Answer:

Parabola

Step-by-step explanation:

We are given that a function

$f(x)=(x-5)^2+3$

The given function is an equation of parabola along y- axis.

General equation of parabola along y- axis with vertex (h,k) is given by

$(y-k)=(x-h)^2$

$y=(x-h)^2+k$

Compare it with given equation then we get

h=5, k=3

Vertex of given parabola =(5,3)

Substitute x=0 then we get

$f(0)=(0-5)^2+3=28$

y-intercept of parabola is at (0,28).
