Graph the image of this triangle after a dilation with a scale factor of 1/2 centered at (-5,1)
1 answer:
Answer:
Red triangle on the diagram
Step-by-step explanation:
The center of dilation is point D(-5,1). The scale factor is 1/2. This means that all distances need to be halved.
If triangle ABC has vertices A(-1,7), B(7,9) and C(3,1), then the image triangle has vertices at points E(-3,4), G(1,5) and F(-1,1).
Points E, G and F are midpoints of the segments DA, DB and DC (see attached diagram for details).

Answer:
492 gallons
Step-by-step explanation:
Total gallons of water collected = 4212
Gallons used for watering of plants = 114
Remaining gallons = 4212 - 114
= 4098
She uses 12% of the remaining water to was her laundry.
So that, gallons of water used to wash her laundry = 12% of 4098
= × 4098
= 491.76
≅ 492
She uses 492 gallons to wash her laundry.
