Answer:

Proportional relationship.

Step-by-step explanation:

From the given table, let us find the ratio of each pair of time and distance.

The first pair is 2 and 90.

Therefore, the ratio is $r=\frac{90}{2}=45$

The second pair is 3 and 135.

Therefore, the ratio is $r=\frac{135}{3}=45$

The third pair is 5 and 225.

Therefore, the ratio is $r=\frac{225}{5}=45$

The fourth pair is 6 and 270.

Therefore, the ratio is $r=\frac{270}{6}=45$

Since, the ratio of each pair is same and equal to 45, therefore, the relationship is proportional relationship.

Step-by-step explanation:

Two of the sides are 13.5 inches by 2.5 inches, two sides are 13.5 inches by 8 inches, and two sides are 2.5 inches by 8 inches.

Surface area = 2*13.5*2.5 + 2*13.5*8 + 2*2.5*8

What are the real and complex solutions of the polynomial equation X^3-216=0

vazorg [7]

Answer:

$6,\ -3+3\sqrt{3}i,\ -3-3\sqrt{3}i$

Step-by-step explanation:

Factor the equation $x^3-216=0$ using formula for difference of the cubes:

$x^3-216=(x-6)(x^2+6x+36),$

then

$x-6=0\ or\ x^2+6x+36=0.$

1. The equation $x-6=0$ has real solution $x=6.$

2. The equation $x^2+6x+36=0$ has negative discriminant $D=6^2-4\cdot 36=36-144=-108,$ then it has two complex solutions

$x_{1,2}=\dfrac{-6\pm 6\sqrt{3}i}{2}=-3\pm3\sqrt{3}i.$
