What are the coordinates of the image of Q for a dilation with center (0, 0) and scale factor 1/2?
Amanda [17]
The answer would be D. (2,2)
Since the scale factor is 1/2, all you have to do is multiply 1/2 by each of x-coordinate and y-coordinate of Q.
Multiplying by 1/2 is the same as dividing by 2, so you divide the x and y coordinates of Q to get the dilation image of Q as (2,2).

Annie estimates that the height of a bookcase is 78.25 in. The actual height is 75.50 in.
tankabanditka [31]

Answer:

The percentage error is 3.6 % .

Step-by-step explanation:

Formula

Error\ percentage = \frac{Error\times 100}{Exact\ value}

Error = \left |Approx - Exact \right |

As given

Annie estimates that the height of a bookcase is 78.25 in. The actual height is 75.50 in.

Here

Approx value =  78.25 in

Exact value = 75.50 in

Error = \left |78.25 - 75.50\right |

Error = 2.75

Put in the formula

Error\ percentage = \frac{2.75\times 100}{75.50}

Error\ percentage = \frac{275}{75.50}

Error percentage = 3.6 %

Therefore the percentage error is 3.6 % .
