√- 81 doesn't result in a rational number because you can't get a negative from squaring any number. Instead you get a number with an imaginary number. 

13 - √- 81 = 13 - 9i

natita [175]

Answer:

84 arrangements

Step-by-step explanation:

First, we need to calculate the total number of roses that the shop owner has. We do this by adding the pink roses and the red roses that the owner has.

342 + 330 = 672 total roses

Now that we have the total number of roses we simply divide by the number of roses needed for each arrangement (8) in order to calculate the total number of arrangements that the owner can make.

672 / 8 = 84 arrangements

Use the Distance Formula to find the distance between (13, 1) and (9,- 4), rounded to the nearest hundredth.
valina [46]

Answer:

  about 6.40 units

Step-by-step explanation:

The distance formula is ...

  d = √((x2 -x1)^2 +(y2 -y1)^2)

For the given points, the distance between them is ...

  d = √((9 -13)^2 +(-4-1)^2) = √((-4)^2 +(-5)^2) = √(16 +25)

  d = √41 ≈ 6.40

The distance between the points is about 6.40 units.
