2 and 4

Step-by-step explanation:

the number of years after 2000 cannot be negative, nut it can be 0 since you can say that it is the year 2000

so an inequality would be t is greater than or equal to 0, and you can write this as t 0

4 is just saying what t 0 in word form: t is greater than or equal to 0

the length of o'p' is .

step-by-step explanation:

it is given that the quadrilateral m'n'o'p' is the image of quadrilateral mnop after dilation.

the center of dilation is origin and the scale factor is 1.5.

in dilation the image and preimge are similar figures. it means the sides of image and preimage are proportional.

the scale factor is defined as

the scale factor is 1.5.

multiply both sides by op.

note: if the value of op is given, then multiply the value of op with 1.5 to get the length of side o'p'.

therefore length of o'p' is .
