So, on day 1, the plant was say "P" cm tall.
then 2 weeks go by, or 14 days, and the plant grew to 452 cm.
Out of the choices, the entities with only one dimension and have infinite length are the line and ray. The line extends to both sides while the ray is restricted by an endpoint on one side but can extend infinitely to the other side. The answers are therefore letter D and F.
Answer:
±5sqrt(2) = x
Step-by-step explanation:
50 - x^2 = 0
Add x^2 to each side
50 - x^2 +x^2= 0+x^2
50 = x^2
Take the square root of each side
±sqrt(50) = sqrt(x^2)
±sqrt(25*2)) = x
±sqrt(25) sqrt(2) = x
±5sqrt(2) = x
