Answer:

$66 for 6 cars.

Step-by-step explanation:

This is a rather simple problem. To find the answer you must divide 44/4= 11. Now knowing that Chris earns $11 per car if you multiply 11x6= 66 you can find out Chris makes $66 for 6 cars.

Andreas93 [3]

The identity Sin(α)/Tan(α) = Cos(α) is valid

Trigonometry is study of triangles. All trigonometric ratios are defined using the sides of the right triangle, such as an adjacent side, opposite side, and hypotenuse side. Three major of them are as follows :-

Sine Function:

sin(θ) = Opposite / Hypotenuse

Cosine Function:

cos(θ) = Adjacent / Hypotenuse

Tangent Function:

tan(θ) = Opposite / Adjacent

Lets prove this identity by proceeding with the LHS

= Sin(α)/Tan(α)

= Sin(α)/ (Sin(α)/Cos(α)) (Tan(α) = Sin(α)/Cos(α))

= Sin(α)xCos(α) / Sin(α)

= Cos(α)

Hence verified

Answer:

a) 2

b) -\frac{1}{2}

c) y = 2x + 1

Step-by-step explanation:

a)

First put the equation into slope intersept form (y=mx+b) by...

  • Move the variable to the right-hand side and change its sign : -y = -4 -2x
  • Change the signs on both sides of the equation: y = 4 + 2x
  • Use the commutative property to reorder the terms : y = 2x + 4

Slope intersept form : y = 2x + 4

Parallel lines have the same slope so.... a parallel slope is 2

b)

First put the equation into slope intersept form (y=mx+b) by...

  • Move the variable to the right-hand side and change its sign : -y = -4 -2x
  • Change the signs on both sides of the equation: y = 4 + 2x
  • Use the commutative property to reorder the terms : y = 2x + 4

Slope intersept form : y = 2x + 4

To find a perpendicular slope flip the slope and change the sign : -\frac{1}{2}

c)

First put the equation into slope intersept form (y=mx+b) by...

  • Move the variable to the right-hand side and change its sign : -y = -4 -2x
  • Change the signs on both sides of the equation: y = 4 + 2x
  • Use the commutative property to reorder the terms : y = 2x + 4

Slope intersept form : y = 2x + 4, parellel slope : 2

  • Substitute the x and y values with the given ordered pair: 3 = 2(1) + b
  • Calculate the product: 3 = 2 + b
  • Move the variable to the left-hand side and change its sign: -x = 2 - 3
  • Calculate the difference and change the signs : b = 1

Use the slope and y-intersept (b) to write the new line : y = 2x + 4
