Answer:
-22%
Step-by-step explanation:
The percent decrease can be found by subtracting the original amount from the sale price. Divide the result by the original price and multiplying the decimal by 100 for the percent.
670.80 - 860 = -189.2
-189.2/860 = -0.22
-0.22*100 = -22%
Answer:
The coordinates of E are .
Step-by-step explanation:
The triangle ABC represents a right triangle as both sides AB and AC are orthogonal to each other. The side AB is in the y axis, whereas the side AC is in the x axis. The triangle is dilated with respect to the origin, in which point A is set.
Vectorially speaking, dilation is defined by the following operation:
(1)
Where:
- Point of reference.
- Original point.
- Dilated point.
- Dilation factor.
By applying this operation, point B becomes point D:
,
Lastly, we transform point C into point E by applying the same operation: , and
The coordinates of E are .
