A bedroom measures 9 feet long and 11 feet wide. A scale drawing is made using a scale factor of 112.
bazaltina [42]

Given the previous length of the bedroom and the current scale factor, the length of the bedroom in the current scale drawing is 1008ft.

<h3>What is the length of the bedroom in the scale drawing?</h3>

Scale factor is simply a measure for similar figures, who look the same but have different scales or measures.

To get new dimension;

New dimension = scale factor × current dimension

Given that;

  • Current length of the bedroom = 9ft
  • Current width of the bedroom = 11ft
  • Scale factor = 112
  • New length of the bedroom = ?

New dimension = scale factor × current dimension

New length of the bedroom = 112 × 9ft

New length of the bedroom = 1008ft

Therefore, given the previous length of the bedroom and the current scale factor, the length of the bedroom in the current scale drawing is 1008ft.

F(x) = x^2. What is g(x)?
marshall27 [118]

Answer:

g(x) = -x^2 - 4

Step-by-step explanation:

f(x) = x^2

To flip the graph, you need the negative of the right side,

y = -x^2

This is a parabola that opens downward, but the vertex is at (0, 0).

Now you need to translate the graph 4 units down, so subtract 4 from -x^2.

g(x) = -x^2 - 4
