Q 13 roots of equation

the roots of the second equation are
x1 = 1/3(-0.693) = -0.231
x2 = 1/3(1.443) = 0.481
the equation is
(x+0.231)(x-0.481)=0

Using Pythagoras in the first question
c=

which is approximately 16.5
for the second question
we also use Pythagoras

The formula is A=p(1 + (r/n))^(nt)
A = 3500(1 + (.08/4))^(4*2)
A = 3500 ( 1.02)^8
A = $ 4100.81
The decimals that represent the portions of the words that Tomas spelled correctly is 0.9 or 0.90.
You'll have to show work guaranteed.......so i'll tell you that you need to inverse
