Answer:
I believe its (- 2, 2 )
Step-by-step explanation:
Assuming the dilatation is centred at the origin, then multiply the coordinates of B by the scale factor 2, that is
B(- 1, 1 ) → B'(2(- 1), 2(1) ) → B'(- 2, 2 )
Answer:
r = 7.7
Step-by-step explanation:
A = πr²
60π = πr²
r² = 60π/π
r² = 60

r = 7.746
Rounded to tenths:
7.7

speed equals 825 divided by 17
speed equals to 48.5miles per hour
gas mileage equals to 825/38
gas mileage equals to 21.7
125/38 equals to 3.3 unit price
