Answer:
no solution
Step-by-step explanation:
The discriminant is ...
b^2 -4ac = (-4)^2 -4(2)(16) = 16 -128 = -112
A negative discriminant means there are no real solutions to the equation.
_____
The complex solutions are 1±i√7.
If we assume the equation has a typographical error and is intended to be ...
2x^2 -4x -16 = 0
The solutions are x = -2 and x = 4.
Answer:
$4.03
Step-by-step explanation:
because 15% of 3.50 is 0.525
take 0.525 and round it up (0.53)
3.50 + 0.53 = $4.03
1.847 rounds to 1.85 because the number in the thousandths place bumps it up since it is greater then 4. 1.798 rounds to 1.8 because the number in the thousandths place bumps the nine up to ten and you can't have a two digit number where there is only supposed to be one. so that "ten" bumps the 7 up to 8.
