Answer:

-33 - 21i

Step-by-step explanation:

3i (-7 + 11i)

= -21i + 33i^2                   (i^2 = -1)

= -21i + 33(-1)

= -33 - 21i

3i(-7+11i)=-28i+33i^2=\boxed{-33-28i}

HELP ASAP!! WILL MARK AS BRAINLIEST IF ANSWERED NOW!!!!

Answer: She should blend 98 lbs of high-quality beans.

She should blend 72 lbs of cheaper beans

Step-by-step explanation:

Let x represent the number of pounds of high quality beans that she should blend.

Let y represent the number of pounds of cheaper beans that she should blend.

She needs to prepare 170 lbs of blended coffee beans. This means that

x + y = 170

She plans to do this by blending together a high-quality bean costing $4.75 per pound and a cheaper bean at $2.00 per pound. The blend would sell for $3.59 per pound. This means that the total cost of the blend would be 3.59×170 = $610.3. This means that

4.75x + 2y = 610.3 - - - - - - - - - -1

Substituting x = 170 - y into equation 1, it becomes

4.75(170 - y) + 2y = 610.3

807.5 - 4.75y + 2y = 610.3

- 4.75y + 2y = 610.3 - 807.5

- 2.75y = - 197.2

y = - 197.2/-2.75 = 71.9

y = 72 pounds

x = 170 - y = 170 - 71.9

x = 98.1

x = 98 pounds

The volume of a cone is 37x3 cubic units and its height is x units.
Alla [95]

Answer:

  6x

Step-by-step explanation:

The formula for the volume of a cone is ...

  V = (π/3)r²h

Filling in the given values and solving for r, we find ...

  37x³ = (π/3)r²x

  (3·37/π)x² = r² . . . . . . . . divide by the coefficient of r²

  x√35.3324 ≈ r ≈ 5.94x

The closest answer choice is 6x.
