What is the factored form of 125x6 – 8?(5x2 – 2)(25x4 – 10x2 – 4)
(5x2 – 2)(25x4 – 10x2 + 4)
(5x2 – 2)(25x4 + 10x2 + 4)
(5x2 – 2)(25x4 + 10x2 – 4)

Answers

If you would like to know the factored form of 125x^6 - 8, you can find this using the following steps:

125x^6 - 8 = (5x^2 - 2) * (25x^4 + 10x^2 + 4)

The correct result would be (5x^2 - 2) * (25x^4 + 10x^2 + 4).

P (1+r)^n $750 at 7% for 9 years compounded annually
Total amount=
Interest amount=

Answers

Answer with Step-by-step explanation:

Total amount = $P(1+r)^n$

Here, P=$750

r=7/100=0.07

n=9

Total amount=

$750(1+0.07)^9\n\n=750* 1.07^9\n\n=\$ 1378.8$

Interest amount=Total amount-Initial amount

=1378.8-750

= $628.8

Hence,

Total amount=

$1378.8

Interest amount=$628.8

A = 750(1+0.07)^9
A = $1378

$1378 - $750 = $628

total amount = $1378
interest amount = $628

The table shows the approximate measurements of the Great Pyramid of Giza in Egypt and the Pyramid of Kukulcan in Mexico.Pyramid Height (meters)
Area of the Base

(square meters
Pyramid Height (meters)
Great Pyramid of Giza 147 52,900
Pyramid of Kukulcan 30 3,025

Approximately what is the difference between the volume of the Great Pyramid of Giza a

Answers

Answer:

The difference in the volume between the Great Pyramid of Giza and the Pyramid of Kukulcan is approximately 2561850 m³

Step-by-step explanation:

Here we have both pyramids as rectangular pyramids, therefore, volume of pyramid is given by Volume = $(1)/(3) * Area \ of \ base \ * Height$

For the Great Pyramid of Giza,

Height = 147 meters

Area of base = 52900 m²

Volume = 1/3 × 52900 ×147 = 2592100 m³

For the Pyramid of Kukulcan,

Height = 30 meters

Area of base = 3,025 m²

Volume = 1/3 × 3,025 × 30= 30250 m³

Therefore, the difference in the volume of the two pyramids is approximately 2592100 m³ - 30250 m³ = 2561850 m³.
