Astudent claimed that the transformation (x, y) (3x, y) is a rigid motion because the segment joining (4,0) to (4,2) is transformed to the segment joining (12,0) to (12,2) and both of these segments have the same length complete the explanation of the students error

the distance between point a and point b is 6 units

3+3+3+2*2*2+29*12 = 365

step-by-step explanation:

there are 14 dogs at the park now

answer-

the equation that models this pattern is

solution-

a researcher placed a petri dish with 32,000 bacterial cells. one hour after being placed in the vacuum chamber, the number of cells in the petri dish had halved. another hour later, the number of cells had again halved.

this can be represented as exponential decreasing function,

where,

putting the values,

y-intercept means, where x=0, so

the coordinate of this poin will be (0, 32000)

this means when x=0 or at the starting of the research, the number of bacteria cells was 32000.

after 3 hours, number of bacteria cells will be,

the   coordinate of this point will be (3, 4000)
