remember
[tex]
log_{z}x^{m}=mlog_{z}x [/tex]
base is z
log x (base z) to the m
power equals m times log x (base z)
and
[tex] y=log_{z}x means z^y=x [/tex]
y=1/4log(base2)
(8x-56)^16-12
move exponent down (16, to the front)
1/4 times
16=4
so we have
[tex]
y=4log_{2}(8x-56)-12 [/tex]
area one
split up
3 sides of a recatgle
1/2 circumference of circle
the sides are
19+32+32=83
semicircle
1/2pid
d=19
1/2*19*3.14=29.83
add
29.83+83=112.83 ft
