Answer:

Step-by-step explanation: Part A:

3x−6y=−12;x−2y=−8

Rewrite equations:

x−2y=−8;3x−6y=−12

Step: Solvex−2y=−8for x:

x−2y=−8

x−2y+2y=−8+2y(Add 2y to both sides)

x=2y−8

Step: Substitute2y−8forxin3x−6y=−12:

3x−6y=−12

3(2y−8)−6y=−12

−24=−12(Simplify both sides of the equation)

−24+24=−12+24(Add 24 to both sides)

0=12

Answer:

No solutions.

Part B: the lines are parallel

Angle θ is in standard position. If (8, -15) is on the terminal ray of angle θ, find the values of the trigonometric functions.
notsponge [240]

ANSWER

\sin( \theta)   =  -  \frac{15}{17}

\csc( \theta)   =  -  \frac{17}{15}

\cos( \theta)   =   \frac{8}{17}

\sec( \theta)   =    \frac{17}{8}

\tan( \theta)   =  -  \frac{15}{8}

\cot( \theta)   =  -  \frac{8}{15}

EXPLANATION

From the Pythagoras Theorem, the hypotenuse can be found.

{h}^{2}  = 1 {5}^{2}  +  {8}^{2}

{h}^{2}  = 289

h =  \sqrt{289}

h = 17

The sine ratio is negative in the fourth quadrant.

\sin( \theta)  = -   \frac{opposite}{hypotenuse}

\sin( \theta)   =  -  \frac{15}{17}

The cosecant ratio is the reciprocal of the sine ratio.

\csc( \theta)   =  -  \frac{17}{15}

The cosine ratio is positive in the fourth quadrant.

\cos( \theta)   =  \frac{adjacent}{hypotenuse}

\cos( \theta)   =   \frac{8}{17}

The secant ratio is the reciprocal of the cosine ratio.

\sec( \theta)   =    \frac{17}{8}

The tangent ratio is negative in the fourth quadrant.

\tan( \theta)   =  -  \frac{opposite}{adjacent}

\tan( \theta)   =  -  \frac{15}{8}

The reciprocal of the tangent ratio is the cotangent ratio

\cot( \theta)   =  -  \frac{8}{15}

1. What is the difference between heat capacity, specific heat, and latent heat? 2. Explain what is physically meant by "Degrees
alisha [4.7K]

Answer:

1.

- Heat capacity is defined as the total amount of heat required to increase the temperature of a substance in 1°C.

- Specific heat is defined as the total amount of heat required to increase the temperature of a substance in 1°C per unit mass. Hence this property depends of the mass of the substance.

- Latent heat is the amount of energy absorbed or released by a substance in a phase change (physical change) without a change in temperature.

2.

- Degrees of freedom is the number of parameters that define the configuration of a system. For example, in a system with we want to know about the dynamic in the three dimension x,y,z and also about the rotation around a fixed axe we have four degrees of freedom.

- Equipartition theorem relates the temperature of a system with the average energy of the system (this average is taken for those degrees of freedom that appears quadratically).

I hope this is useful for you

Hometown Donuts tracked how many of each type of donut were recently sold.
ziro4ka [17]

Answer:

4.62%

Step-by-Step Explanation:

Ask yourself: "3 is what percent of 65?" and solve.

Percentage solution with steps:

Step 1: We make the assumption that 65 is 100% since it is our output value.

Step 2: We next represent the value we seek with <em>x</em>.

Step 3: From step 1, it follows that 100%=65.

Step 4: In the same vein, x%=3.

Step 5: This gives us a pair of simple equations:

100%=65(1)

x%=3(2)

Step 6: By simply dividing equation 1 by equation 2 and taking note of the fact that both the LHS

(left hand side) of both equations have the same unit (%); we have

100% / x% =65 / 3

Step 7: Taking the inverse (or reciprocal) of both sides yields

x% / 100% =3 / 65

---> x = 4.62%

Therefore, 3 is 4.62% of 65.
