Answer:

87.86 feet.

Step-by-step explanation:

We know that there is 30.48 cm in 1 foot. So to find how many feet are in 2678 cm, we need to divide it by 30.48

2678 / 30.48 = 87.86

Find a degree 3 polynomial with real coefficients having zeros 3 and 3−3i and a lead coefficient of 1. Write P in expanded form.
LekaFEV [45]

Answer:

P =  x³ − 9x² + 36x − 54

Step-by-step explanation:

Complex roots come in conjugate pairs.  So if 3−3i is a zero, then 3+3i is also a zero.

P = (x − 3) (x − (3−3i)) (x − (3+3i))

P = (x − 3) (x − 3 + 3i) (x − 3 − 3i)

P = (x − 3) ((x − 3)² − (3i)²)

P = (x − 3) ((x − 3)² + 9)

P =  (x − 3)³ + 9 (x − 3)

P =  x³ − 9x² + 27x − 27 + 9x − 27

P =  x³ − 9x² + 36x − 54

The cylinder shown has a volume of 30 cubic units. The
yKpoI14uk [10]

The volume of the cone will be 10 cubic units.

<h3>What is volume?</h3>

Volume is defined as the space occupied by any object in the three-Dimensions. All three parameters are required for the volume like length, width and height of the cube or cuboid.

Given that:-

  • The cylinder shown has a volume of 30 cubic units.
  • The cone and the cylinder have the same height and the same base.

The volume of the cone will be:-

Vc   =   Vcyl

\dfrac{1}{3} \pi r^2h\ \ \ =\ \  \pi r^2h

Vc         =    (1  /  3)  Vcyl

Vc         =    ( 1  /  3  ) x  30

Vc         =     10  cubic units

Therefore the volume of the cone will be 10 cubic units.
