Answer:

y+3=-3/5(x + 5)

Step-by-step explanation:

3x+5y=15 has a slope of -3/5. With the point (-5,-3) that would be y + 3= -3/5(x + 5) in point slope form.

Jerome found the lengths of each side of triangle QRS as shown, but did not simplify his answers. Simplify the lengths of each s

Margaret [11]

Answer:

$QR = 6.0033$

$QS = 8.22$

$RS = 6.0033$

QRS is isosceles

Step-by-step explanation:

Given

See attachment for complete question

From the attachment, we have the following parameters $QR = \sqrt{(-3-0)^2+(-5.2-0)^2}$

$QR = \sqrt{9+27.04}$

$QS = \sqrt{(-3-5)^2+(-5.2-(-3.322))^2}$

$QS = \sqrt{64+3.53} = \sqrt{67.53$

$RS = \sqrt{(0-5)^2 + (0 - (-3.322))^2}$

$RS = \sqrt{(25 + 11.04}$

Solving further, we have:

$QR = \sqrt{9+27.04}$

$QR = \sqrt{36.04}$

$QR = 6.0033$

$QS = \sqrt{64+3.53} = \sqrt{67.53}$

$QS = 8.22$

$RS = \sqrt{25 + 11.04}$

$RS = \sqrt{36.04}$

$RS = 6.0033$

From the calculations;

$RS = QR = 6.0033$

<em>This means that: QRS is isosceles</em>

The volume of a gas varies directly with its temperature and inversely with the pressure. If the volume of a certain gas is 15 c

vladimir2022 [97]

Answer:

Therefore the volume of the gas is 32 cubic feet.

Step-by-step explanation:

Given that,

The volume of a gas varies directly with its temperature and inversely with the pressure.

$V\propto \frac{T}{P}$

V= Volume of the gas at constant mass

T= Temperature at constant mass

P= pressure at constant mass

$\frac{V_1}{V_2}=\frac{\frac{T_1}{T_2}}{\frac{P_1}{P_2}}$

$\therefore \frac{V_1}{V_2}=\frac{T_1P_2}{T_2P_1}$ .

Given that,

At constant mass, the volume of a certain gas is 15 cubic feet and a pressure of 40 pound per square inch at a temperature 300 k.

$V_1$ =15 cubic feet, $P_1$ =40 pound per square inch and $T_1$ = 300 K

$V_2=?$ , $P_2$ =20 pound per square inch and $T_2$ = 320k

$\therefore \frac{V_1}{V_2}=\frac{T_1P_2}{T_2P_1}$ .

Plugging all values

$\frac{15}{V_2}=\frac{300\times 20}{320\times 40}$

$\Rightarrow V_2=\frac{15\times 320\times 40}{300\times 20}{}$

$\Rightarrow V_2=32$ cubic feet

Therefore the volume of the gas is 32 cubic feet.
