…99 . Math 151 written Work #4- Due Sunday, May 12th Spring 2019 Name collect written works to verify that you are able to show your work neatly and fully. While I care that you get the correct answer, it's also about communicating well about how you got your answer. This written work about showing that you know how show your work on problems that have multiple steps Let f(x) 8-5log (2x +4) Find the exact area of the triangle enclosed by the tangent line to (n) atx3, the x-axis, and the y axis. (Thi /won't be exact.) Be sure to draw a picture of what this problem is about. is is all in the 1st quadrant.) Do not use your calculator to evaluate anything (your answer 2 points for a graph (picture), with everything labeled (using variable(s)), 4 points for finding the exact area of the triangle Remember, you shouldn't be touching ur calculator to do anything here RRCa points for finding the equation of the tangent line exactly.

Answer 1

ven : -{ (a ): 8-slag(2x +4) Step 1: st os au we find Gi ta the tanet i - 1 So sLo pe dy 4 2 x + 4 8 2 (2) +4 (zy)(2, 8) So on point

Step: 2 Now we find the closed hia la axis n and y-x ISIn whin yo (01 42-4002 0

Step-3 A we find the are A tx) da 4 42 612 42-60 2 4 1 l o 42一60 × 0.3010) 2 2 ะ 0.3010 4-13 o) (25 94)
