The rate of growth in the tree is 4 feet per year.

Height of tree at year 0 = 2 feet

Height of tree at year 1 = 6 feets

Therefore, the difference in the heights of the tree from the previous year will be:

= 6 feet - 2 feet.

= 4 feet

Line CD is the perpendicular bisector of segment AB. The lines intersect at point E. Which of these statements is true?
fredd [130]

Answer:

C. E is the same distance from A and B.

Step-by-step explanation:

Line CD is a perpendicular that divides segment AB into two equal parts as it intersects segment AB at point E.

This divides AB into AE and EB.

Point E is the middle of A and B. Therefore, E will be the same distance from A and from B.

That is, AE = EB.

Therefore, the statement that is true is: C. E is the same distance from A and B.
