Answer:

A jagged curve

The coordinates of quadrilateral VWXY are given below. Find the coordinates of its image after a dilation with the given scale f
Lapatulllka [165]

Answer:

The coordinates of its image after dilation by a scale factor of 2 will be:

  • V'(12, 4)
  • W'(-4, 8)
  • X'(-6, -10)
  • Y'(6, -10)

Step-by-step explanation:

Given the quadrilateral VWXY

  • V(6, 2)
  • W(-2, 4)
  • X(-3, -5)
  • Y(3, -5)

A dilation by a scale factor of 2 means every coordinate of the original quadrilateral gets multiplied by the scale factor (x2).

<u>Using the formula of dilation by a scale factor of 2</u>

Dilation with scale factor 2, multiply by 2

(x, y) → (2x, 2y)

Thus, the coordinates of its image after a dilation will be:

(x, y)          →           (2x, 2y)

V(6,2)        →         (2(6), 2(2))        =      V'(12, 4)

W(-2, 4)     →         (2(-2), 2(4))       =      W'(-4, 8)

X(-3, -5)     →         (2(-3), 2(-5))      =      X'(-6, -10)

Y(3, -5)      →          (2(3), 2(-5))       =      Y'(6, -10)

Therefore, the coordinates of its image after dilation by a scale factor of 2 will be:

  • V'(12, 4)
  • W'(-4, 8)
  • X'(-6, -10)
  • Y'(6, -10)

A boat took 5 h to travel 60 km up a river, against the current. The return trip took 3 h. Find the speed of the boat in still w
Dafna11 [192]

Answer:

Correct answer: V₁ boat = 16 km/h and V₂ current = 4 km/h

Step-by-step explanation:

If we take speed (velocity) of the boat as V₁ and speed of the current V₂

Let us form equations:

Traveling down the current  V₁ + V₂ = 60/3 = 20 km/h

Traveling against the current  V₁ - V₂ = 60/5 = 12 km/h

V₁ - V₂ = 12

V₁ + V₂ = 20

If we add up the left and right sides of the equations we get:

2 V₁ = 32  =>    V₁ = 32/2 = 16 km/h

from the second equation we get:

V₂ = 20 - V₁ = 20 - 16 = 4 km/h

V₂ = 4 km/h

I NEED HELP PLEASE !!!!
Sergio [31]

Answer:

Step-by-step explanation:

2x + 3.5x + 15 = -1.5

5.5x + 15 = -1.5

5.5x = -16.5

x = -3

y = 3.5(-3) + 15

   = -10.5 + 15

    = 4.5

(-3, 4.5)
