Y = e^tanx - 2
To find at which point it crosses x axis we state that y= 0
e^tanx - 2 = 0
e^tanx = 2
tanx = ln 2
tanx = 0.69314
x = 0.6061
to find slope at that point first we need to find first derivative of funtion y.
y' = (e^tanx)*1/cos^2(x)
now we express x = 0.6061 in y' and we get:
y' = k = 2,9599

Answer:
c = 2
Step-by-step explanation:
26 - (2c + 4) = 2(c+6) + c
26 - 2c + 4 = 2c + 12 + c
26 - 4 - 12 = 2c + 2c + c
10 = 5c
2 = c
Divide the figure into 3 shapes
top square
middle trapezoid
bottom rectangle
so
Area of figure
= (10x10) + 1/2(8 + 14)(4) + (20 x 6)
= 100 + 44 + 120
= 264
answer
264 cm^2
