Answer:
Other root is -95i
Step-by-step explanation:
Here, Nature of roots of f(x) is imaginary roots.
Therefore, Roots are conjugate of each other.
Conjugate of x + yi is x - yi.
we get conjugate of 95i as -95i
Verification shows....
(x-95)(x+95i)=0
this, roots are -95i and 95i

Answer:
$35.97
Step-by-step explanation:
the regular price is 59.95
40% discount so
let's say the price now is x and i am gonna do fractions
x/59.95 = 40%/100
100 x X = 100x
59.95 x 40 = 2398
i divide 2398 by 100 which equal 23.98
40% is 23.98 and then i do 59.95 - 23.96 = 35.97
DONE!
