Answer:
C would be the correct answer
Step-by-step explanation:
Answer:
B. The student incorrectly calculated the scale factor to be –2
Step-by-step explanation:
Given that :
After a dilation with a center of (0, 0), a point was mapped as (4, –6) → (12, y).
The student determined y to be -2
If a figure dilated with a center of (0, 0) and scale factor k, then
(x , y) → (kx , ky)
(4, -6) → (12, y)


k = 3
Thus; the scale factor is 3
Now; the y-coordinate can now be calculated as;
ky = (3 × -6)
ky = -18
Therefore; the value of y = -18 and the student incorrectly calculated the scale factor to be -2.
Step-by-step explanation:
5x 3 1/2 = 3 x 5 1/2 is false
Answer:
A. the one in the table because after two hours it is the size of the one that began at 20 cm
B. the one describes by the graph because after 10 hours it would be 0 cm and the one described by the equation would be 5 cm
C. the one described by the graph will burn out in 10 hours as shown in the graph and the one described by the equation will burn out in 12 hours
