Answer: The average annual rate of appreciation of the land over this 5-year period is 12%

Step-by-step explanation:

Calculating the amount of appreciation, we say,

$96,000 - $60,000 = $36,000

Then, $36,000/5 years = $7,200 per year.

Finally, $7,200/$60,000 = 0.12

0.12 x 100% = 12%

Princess Poly claims that the equation (3x−4i)(7x−8)(3x+4i)=0 has three roots, a real root and a complex root with a multiplicit
Serjik [45]

Given equation:

(3x-4i)(7x-8)(3x+4i)=0

i.e., 3x-4i=0       and       7x-8=0       and       3x+4i=0

i.e., 3x=4i       and       7x=8       and       3x=-4i

i.e., x=\frac{4i}{3}       and       x=\frac{8}{7}       and       x=-\frac{4i}{3}

Therefore, the given equation has a real root i.e., x=\frac{8}{7}

and two complex conjugate roots i.e., x=\frac{4i}{3} and x=-\frac{4i}{3}

Hence, option C is correct.

While playing with magnetic building tiles, Natalie constructed a square pyramid out of
Dovator [93]

The height of the green pyramid constructed  by Natalie while playing with magnetic building tiles is 26.25 cm.

<h3>Volume of the orange pyramid</h3>

The volume of the orange pyramid is calculated as follows;

V = ¹/₃Ah

where;

  • A is the base area of the pyramid
  • h is the height of the pyramid

V = ¹/₃ x (7²) x 5

V  = ¹/₃ x (245 cm³)

<h3>Volume of the green pyramid</h3>

Voume = 21 x [¹/₃ x (245 cm³)]

Volume = 1,715 cm³

<h3>Height of the green pyramid</h3>

V = ¹/₃Ah

3V = Ah

h = 3V/A

h = (3 x 1715) / (14²)

h = 26.25 cm
