Answer:

r=(A/π)^1/2

Step-by-step explanation:

A=πr^2.  When dividing π on both sides, you get r^2 = A/π. Meaning that r = the square root of A/π, or (A/π)^1/2

The equation to show the depreciation at the end of x years is

f(x) = 1500 - 200x

Data;

  • cost of machine = 1500
  • annual depreciation value = x

<h3>Linear Equation</h3>

This is an equation written to represent a word problem into mathematical statement and this is easier to solve.

To write a linear depreciation model for this machine would be

For number of years, the cost of the machine would become

1500 - 200x

This is properly written as

f(x) = 1500 - 200x

where x represents the number of years.

For example, after 5 years, the value of the machine would become

f(x) = 1500 - 200x\\f(5) = 1500 - 200(5)\\f(5) = 1500 - 1000\\f(5) = 500

The value of the machine would be $500 at the end of the fifth year.

From the above, the equation to show the depreciation at the end of x years is f(x) = 1500 - 200x

32^(x+4) = 64^(2x-1)
Rudik [331]

Answer:

Vamos a resolver la ecuación paso a paso.

32x+4=642x−1

Step-by-step explanation:

Resolver el exponente.

32x+4=642x−1

log(32x+4)=log(642x−1)(Sacar el logaritmo de ambos lados.)

(x+4)*(log(32))=(2x−1)*(log(64))

x+4=(

log(64)

log(32)

)*(2x−1)

x+4=1.2*(2x−1)

x+4=2.4x−1.2(Simplificar ambos lados de la ecuación)

x+4−2.4x=2.4x−1.2−2.4x(Restar 2.4x a ambos lados)

−1.4x+4=−1.2

−1.4x+4−4=−1.2−4(Restar 4 a ambos lados)

−1.4x=−5.2

−1.4x

−1.4

=

−5.2

−1.4

(Dividir ambos lados por -1.4)

x=3.714286

Solución:

x=3.714286

Goodmorning all help me guys​
kotegsom [21]

Answer:

Step-by-step explanation:

1) Distance covered by motorcycle = x

y  = 50 + (x -2)*10

2)Distance traveled = 5 km

y = 50 + ( 5-2) *10

  = 50 + 3*10

  = 50 + 30

  = 80

Seth will be paid Php 80

3)  y = 120

50 + (x - 2)* 10 = y

50 + (x -2) *10 = 120

50 + 10x - 2*10 = 120

50 + 10x - 20  = 120

30 + 10x = 120

       10x = 120 - 30

       10x = 90

           x = 90/10

x = 9

A passenger can travel 9 km.

4)y = (x - 2)*10

 y = 10x - 20

20 + y = 10x

     20 = 10x - y

10x - y = 20      {Ax + By = C form}
