Answer:

56÷2=28

Circumference=2×3.142×r

c= 2×3.142×28=175.952

hundredth =175.95cm

Area=3.142×r^2

A= 3.142×28^2=2463.328

hundredth =2463.33cm^2

A tautology will have an infinite number of solutions, as it is true for all possible values of the variable by definition.

Example: 3(x+2) = 3x+6

All other linear equations in one variable will have one solution, which may include values that are undefined or indeterminate.

Examples:

... 3x-2 = 7 . . . solution is x=3

... x = 0/0 . . . . solution is an indeterminate number

... x = 1/0 . . . . solution is undefined

1). Solve for x 3x-6=7x+18
Blizzard [7]
3x - 6 = 7x + 18

(Move terms)

3x - 7x = 18 + 6

(Collect the terms)
(Calculate the sum)


-4x = 24

(Divide both sides by -4)

x = -6

3) Y-3=4(n=2)<br>*to draw graph​​​​
Kazeer [188]

Answer:

[see below]

Step-by-step explanation:

I am assuming that you mean: y-3=4(x-2).

The equation is in point slope form...

y-y_1=m(x-x_1)

The point used in the equation is (2, 3). 2 replaces 'x1' and 3 replaces 'y1'.

If you convert the equation in to slope intercept form:

y-3=4(x-2)\\\\y-3=4x-8\\\\y-3+3=4x-8+3\\\\\boxed{y=4x-5}

You get -5 as the y-intercept.

So, the line you draw would pass through points (2,3) and (0,-5).

Hope this helps.

Un alemán se encuentra situado en una ciudad C y necesita transportar varios cilindros de gas de cloro. Si la ciudad C está situ
Yakvenalex [24]

Answer:

El alemán debe recorrer de la ciudad B a la ciudad A para llevar los cilindros de gas de cloro.

Step-by-step explanation:

De acuerdo con este problema, tenemos un ángulo y dos lados adyacentes, por tanto, podemos determinar la distancia entre las ciudades A y B, medida en kilómetros, por la Ley del Coseno, definida como sigue:

AB = \sqrt{AC^{2}+BC^{2}-2\cdot AC\cdot BC\cdot \cos C} (1)

Donde:

AC - Distancia entre las ciudades A y C, medida en kilómetros.

BC - Distancia entre las ciudades B y C, medida en kilómetros.

C - Ángulo en la ciudad C, medida en grados sexagesimales.

Si tenemos que AC = 5\,km, BC = 8\,km y C = 36^{\circ}, entonces:

AB = \sqrt{(5\,km)^{2}+(8\,km)^{2}-2\cdot (5\,km)\cdot (8\,km)\cdot \cos 36^{\circ}}

AB \approx 4,927\,km

El alemán debe recorrer de la ciudad B a la ciudad A para llevar los cilindros de gas de cloro.
