- 2 2
1
16 = 2⁴
- Express the -16 as a power
![\sqrt[4]{-2^{4}} or \sqrt[4]{2^{4}i^{2}}](https://tex.z-dn.net/?f=%5Csqrt%5B4%5D%7B-2%5E%7B4%7D%7D%20%20or%20%20%20%5Csqrt%5B4%5D%7B2%5E%7B4%7Di%5E%7B2%7D%7D)
Remember that -1 = i²
- Get the fourth root of -16

Answer:
(3 ± √23 * i) /4
Step-by-step explanation:
To solve this, we can apply the Quadratic Equation.
In an equation of form ax²+bx+c = 0, we can solve for x by applying the Quadratic Equation, or x = (-b ± √(b²-4ac))/(2a)
Matching up values, a is what's multiplied by x², b is what's multiplied by x, and c is the constant, so a = 2, b = -3, and c = 4
Plugging these values into our equation, we get
x = (-b ± √(b²-4ac))/(2a)
x = (-(-3) ± √(3²-4(2)(4)))/(2(2))
= (3 ± √(9-32))/4
= (3 ± √(-23))/4
= (3 ± √23 * i) /4

It’s A because a rectangle has 2 pairs of equal sides if it was a square A could be an answer but it’s a rectangle so it’s answer A
Answer:
11.8 % empty
Step-by-step explanation:
volume of cylinder : pi × r² × h
attention ! the question gives us diameter, so for radius we need to cut them in half.
Va = pi × (14/2)² × 9 = pi×49×9 = 1385.44236... ft³
Vb = pi × (10/2)² × 20 = pi×25×20 = 1570.79633... ft³
after filling B with everything in A there is still some empty volume in B
Vb empty = Vb - Va = 185.35397... ft³
so,
100% Vb = 1570.79633... ft³
1% Vb = 15.7079633... ft³
so, how often does 1% of the total volume of B fit into the remaining empty volume of B ?
185.35397... / 15.7079633... = 11.8%
