Good evening Guest!

f(x) = 2x + (k−3)     k=

Here is my opinion:

f(x) = 2x + k−3

f(x) = f(x)

2x + k − 3 = 2x + k − 3

Die Gleichung ist erfüllt für jeden Wert für k.

The equation is satisfied for any value of k.

What is the volume of a cone with the height of five mm and diameter of 24.6 mm

V = (1/3) * (d² pi /4) * h

V = (1/3) * (24.6² mm² * pi / 4) * 5 mm

V = 792.153 mm³

The volume of this cone is 792.153 mm³

Ach du lieber Gott! Da habe ich Mist gebaut.

Dank heureka steht jetzt eine richtige Antwort da.

Hallo Gast!

Wie rechnet man 3x plus 4=x plus 8 ?

3x + 4 = x + 8          [ - x

2x + 4 = 8                [ - 4

2x = 4                      [ / 2

x = 2

Probe:

3 * 2 + 4 = 2 + 8

6 + 4 = 10

10 = 10

The slope is 5/3,
or arctan (5/3) = 59,036°

(9 × 10^-7) × 0.007 = 0.000 000 006 3 = 6.3 × 10^-9

Hello Guest !

What is the value of b in the following question? 3^(4b) = 9^(b + 3) ?

3 ^ (4b) = 9 ^ (b + 3)

4b * lg3 = (b + 3) * lg9

4b * lg3 = b * lg9 + 3 * lg 9

4b * lg3 - b * lg9 = 3 * lg 9

b * (4 * lg3 - lg9) = 3 * lg9

b = 3 * lg9 / (4 * lg3 - lg9)

b = 3

Good morning Guest!

A trapezium of area A = 60 cm² has parallel sides of length a =12 cm and b = 8cm. What is the difference h between two parallel sides?

A = (a + b) * h / 2

h = 2A / (a + b) = 2 * 60 cm² / (12 + 8) cm

h = 6 cm

The difference between two parallel sides is 6 cm.

Guten Morgen Guest!

Find the width of a rectangular prism with a volume of 60 cm³ and a length equal width of 3 cm and a height of 12cm.

This rectangular prism is a square prism.

V = w² * h

w = √(V / h) = √(60 cm³ / 12 cm) = √(5 cm²)

w = 2.236 cm

The width of a rectangular prism is 2.236 cm.
