Guten Abend Gast und radix!

Wer mit Ghz rechnet, kennt sicher

auch die einfache Verhältnisgleichung.

Als Ergänzung:

100% / 3,7Ghz = x / 0,3Ghz

x = 100% * 0,3Ghz / 3,7 Ghz

x = 8,11%

Hallo Guest!

What is the volume of a sphere? Sphere:area of a great circle= 98.5 meters squared

A = pi r²

r = √(A / pi) = √(98.5m² / pi) = 5.59942173703m

V = 4 pi r³ / 3 = 4 pi * (5.59942173703m)³ / 3

V = 735.391 m³

Hallo Gast, hallo radix  !

lg(x⁵)+ 3 / lg(x⁵) = 7 / 2

Versuch eines anderen Weges

Einsetzen :

lg(x⁵) = a

a + 3 / a = 7 / 2

a² + 3 = 7a /2

a² -3,5a + 3 = 0

a1 = 1,5

a2 = 2

lg(x⁵) = 1,5

10^1,5    = x⁵

x = ±⁵√(10^1,5)

x = ±⁵√31,6227766017

x₁ = 1,99526231497

x₂ = - 1,99526231497 entfällt

lg(x⁵) = 2

10²   = x⁵

x = ±⁵√10²

x = ±⁵√100

x₃ = 2,51188643151

x₄ = - 2,51188643151 entfällt

lg(x⁵) + 3 / lg(x⁵) = 7 / 2

lg(1,99526231497⁵)+ 3 / lg(1,99526231497⁵) = 3,5

1,5                           + 3 / 1,5                            = 3,5

lg(2,51188643151⁵) + 3 / lg(2,51188643151⁵) = 3,5

2                               + 3 / 2                               = 3,5

Gruß und gute Nacht!

Hallo Guest!

What is the solution set for x²+6x−16=0?

x² + 6x − 16 = 0

p = 6

q = -16

x_1,2  = - p/2 ±√((p/2)² - q)

x_1,2  = - 6/2 ±√((6/2)² + 16)

x_1,2  = - 3 ±√(9 + 16)

x_1,2  = - 3 ±√25

x₁ = 2

x₂ = -8

Hello sampedrana!

La abscisa de un punto es 2 {nl} y su distancia desde el punto (3, 7) es el 5. {nl} Para encontrar es la ordenada del punto.

Ecuación general de un círculo:

(x - x_p)² + (y - y_p)² = r²

(x - 3)² + (y - 7)² = 5²

abscisa:

x = 2

insertado:

(2 - 3)² + (y - 7)² = 25

1 + (y - 7)² = 25

(y - 7)² = 25 - 1

y - 7 = ±√24

y = 7 ±√24

ordenada:

y₁ = 11.8989794856

y₂ = 2.10102051443

Hallo Gast!

Wie löse ich diese Gleichung nach x auf ?

150 000 000^3 :365,25^2 = x^3 : 225^2

150 000 000³ / 365,25² = x³ : 225²               [ * 225²

x³ = 150 000 000³ * 225² / 365.25²               [ ³√

x = ³√(150 000 000³ * 225² / 365.25²

x = 108 597 406,767

Hello guest!

Antti entered a 10-kilometer race. His goal is to finish in one hour. He starts off sprinting and completes the first 2 kilometers of the race at an average speed of 12 kilometers per hour. To achieve his goal of a one-hour finish time, what average speed must Antti maintain for the last 8 kilometers of the race? Enter your answer as a number in decimal form, without units.

t₂ = s₂/ v₂ = 2km / (12km/h) = 1/6 h

t₈ = s₈ / v₈

v₈ = s₈ / t₈ = 8km / (5/6 h) = 9.6 km/h

Antti have to walk 8 km with 9.6 km/h average speed.
