Find the equation of the line passing through the points (2, 1) and (5, 10).​
Vedmedyk [2.9K]

The equation : y=3x-5

<h3>Further explanation </h3>

Straight-line equations are mathematical equations that are described in the plane of cartesian coordinates

General formula

y-y1 = m(x-x1)

or

y = mx + c

Where

m = straight-line gradient which is the slope of the line

x1, y1 = the Cartesian coordinate that is crossed by the line

c = constant

The formula for a gradient (m) between 2 points in a line

m = Δy / Δx

  • Gradient

\tt \dfrac{10-1}{5-2}=3

  • Equation

\tt y-1=3(x-2)\\\\y-1=3x-6\\\\y=3x-5

Imagine that you have an ideal gas in a 6.70 L container, and that 1450 molecules of this gas collide with a square-inch area of
kakasveta [241]

Answer:

they could collide 241.66 molec / in² by increasing the volume to 40.2L

Explanation:

ideal gas:

<u>Boyle Law</u>: at constant temperature the pressure of a gas varies inversely with the volume

  • V1 * P1 = V2 * P2
  • P = F / A

∴ V1 = 6.70 L;

∴ P1 = 1450 molec / in²

∴ V2 = 40.2 L

⇒ P2 = (( 6.70 L ) * ( 1450 molec/in²)) / 40.2 L

⇒ P2 = 241.66 molec/in²

The rate constant for a certain reaction is k = 5.40×10−3 s−1 . If the initial reactant concentration was 0.100 M, what will the
IceJOKER [234]

Answer : The concentration after 17.0 minutes will be, 4.05\times 10^{-4}M

Explanation :

The expression for first order reaction is:

[C_t]=[C_o]e^{-kt}

where,

[C_t] = concentration at time 't'  (final) = ?

[C_o] = concentration at time '0' (initial) = 0.100 M

k = rate constant = 5.40\times 10^{-3}s^{-1}

t = time = 17.0 min = 1020 s (1 min = 60 s)

Now put all the given values in the above expression, we get:

[C_t]=(0.100)\times e^{-(5.40\times 10^{-3})\times (1020)}

[C_t]=4.05\times 10^{-4}M

Thus, the concentration after 17.0 minutes will be, 4.05\times 10^{-4}M
