What is the length of segment BD

 The length of BD is 2.4

Step-by-step explanation:  BD is a leg of a right triangle, so use the

Pythagorean Theorem  a² + b² = c²  

BC is the hypotenuse here, so that is c = 3

We can use the segment CD as side b = 1.8

We will call BD side a, and solve to find that length.

a² + (1.8)² = 3²   Square the known values of b and c

 a² + 3.24 = 9     Subtract 3.24 from both sides.

a² = 9 - 3.24     Simplify

a²  =  5.76          Find the square root of both sides (Calculator time!)

a = 2.4

Step-by-step explanation:

Given that the  height of the plant f(n), in cm, after n days:

To find n when f(n) = 11.04 cm

i.e. in 2.5 days

2) n cannot go upto infinity

If maximum growth is h, then domain is (0, )

3) Put n=0

y intercept = 10 cm.

4) This gives the initial height of the plant i.e. when n =0

5) Average rate of change = 10(1.04)^n ln 1.04

6) n =1,2,3,4,5

n 1      2               3        4                         5
