Activity 2: Planting Trees The best time to plant trees was 20 years ago
The second best time is NOW
Data from the lumber industry shows that the
older the tree (a), the greater the number of board feet
(n) that can be created from the tree. For a tree that is
160 years old, 18,200 board feet can be used
a) Write an equation in slope-intercept form to represent this situation
b) What does the independent variable represent?
c) What does the dependent variable represent?
d) How much board feet can be used from a tree that is 100 years old?
e) If 6,825 board feet was used from a tree, how old was the tree?

Intersecting secant-tangent theorem states that if a tangent segment and a secant segment are drawn to a circle from an exterior point, then the square of the measure of the tangent segment is equal to the product of the measures of the secant segment and its external secant segment.so to break it down: 1. pq acts as the tangent and ps as the secant with an intersection at p.sr = 21rp = 3x + 3pq = 4x + 4following to equation: tangent squared = the two segments multiplied by each otherso (4x + 4) ^ 2 = (3x + 3) • (21) simplifies to 16x^2 - 31x - 47 = 0 or (16x - 47)(x + 1) x = -1 or x = 47/162. pq acts as the tangent and ps as the secant with an intersection at p (again! )sr = 16rp = xpq = 15(15) ^ 2 = 16 • x225 = 16xx = 225/163. the interesting chords are proportional to each other so a ratio is possible to set up: ap dp 10 3 + x = = —— = pc pb 8 xcross multiple to get 10x = (3 + x)(8)x = 12
