Answer:
Step-by-step explanation:
In general, a scale factor is applied to an original (pre) to obtain an image (post). It is the ratio post/pre that expresses the relationship between image dimensions and original dimensions.
Here, that post/pre ratio is 3/4 = 0.75.
x=1 y=2.5
7 hours
7.5 m
circumference = 360/72 × 3π = 15π
so the radius of the circle =
15π / 2π = 7.5 m
always
The point-slope form:
We have the points (5, -3) and (-2, 9). Substitute:
