How do the 8 differ in 38108
kvasek [131]
The left 8 represents 8000 units.
The right 8 represents 8 units.

Their placement in the number is used to signify the multiplier for the number of units they represent. That is why the number system is called a "place value number system." Each time the digit is moved left one place, its value increases by a factor of 10.

Multiple by moving the decimal point 24.6x100,37x1,000 0.367x10,000,0.005x1000,000 .
lesya [120]

The answers are 2460, 37,000, 3670 and 5000

Step-by-step explanation:

  • Step 1: Find the answers for each by multiplying.

24.6 × 100 = 2460 (moved one decimal point)

37 × 1000 = 37,000

0.367 × 10000 = 3670 (moved three decimal points)

0.005 × 1000,000 = 5000 (moved three decimal points)

Answer:

x = 10 - 10sqrt(3)/3

Approximately 4.2265 cm

Volume = 1539.6 cm³

Step-by-step explanation:

Let the height be x

V = (20 - 2x)(40 - 2x)x

V = (800 - 80x - 40x + 4x²)x

V = 4x³ - 120x² + 800x

dV/dx= 12x² - 240x + 800 = 0

3x² - 60x + 200 = 0

x = [60 +/- sqrt(60² - 4(3)(200))]/6

x = [30 +/- 10sqrt(3)]/3

x = 10 +/- 10sqrt(3)/3

Approximately,

15.7735 and 4.2265

d²V/dx² = 24x - 240

For max, d²V/dx² < 0

So, x = 4.2265

V = (20 - 2x)(40 - 2x)x

Plug in x = 10 - 10sqrt(3)/3

V = 1539.600718
