Find the distance between the point (2, 3) and the line 4x + 3y = 10 (round your answer to the nearest tenth).

Monica [59]

Explanation

Let's first graph the elements:

Using the distance formula we get:

$d=\frac{|4(2)+3(3)-10|}{\sqrt{4^2+3^2}}$ $d=\frac{|7|}{\sqrt{25}}=\frac{7}{5}=1.4$

According to Boyle’s law, PV= K, what was the volume at the time of the first measurement given the following information? Round

Temka [501]

<h2>Hello!</h2>

The answer is:

The first measurement of volume is equal to 835.23 mL.

Boyle's Law equation can be used when the temperature is kept constant, and it establishes a relation between the pressure and volume, showing that when an ideal gas is kept constant, the pressure and volume are inversely proportional.

So, we Boyle's Law equation states that:

$P_{1}V_{1}=P_{2}V_{2}$

Where,

$P_1=FirstPressure\\V_1=FirstVolume\\P_2=NewPressure\\V_2=NewVolume$

Now, if we are looking for the first volume measurement, we need to rewrite the equation as follow:

$P_{1}V_{1}=P_{2}V_{2}\\\\V_{1}=\frac{P_{2}V_{2}}{P_{1}}$

So, substituting the given information and calculating, we have:

$V_{1}=\frac{8.59atm*527mL}{5.42atm}$

$V_{1}=\frac{4526.93atm.mL}{5.42atm}=835.23mL$

Hence, the first measurement of volume is equal 835.23 mL.

Have a nice day!

Please solve, -7x+8=-4(x+1)

omeli [17]

Answer: $x=4$

Simplify both sides of the equation.

$-7x+8=-4(x+1)\\-7x+8=(-4)(x)+(-4)(1)(Distribute)\\-7x+8=-4x+-4$

Add 4x to both sides

$-7x+8+4x=-4x-4+4x\\-3x+8=-4$

Subtract 8 from both sides

$-3x+8-8=-4-8\\-3x=-12$

Divide both sides by -3

$-3x/-3=-12/-3\\x=4$
