Bentley is going to invest $98,000 and leave it in an account for 7 years. Assuming
den301095 [7]

Answer:

The rate of interest for compounded daily is 2.1 6

Step-by-step explanation:

Given as :

The principal investment = $ 98,000

The Time period for investment = 7 years

Let The rate of interest compounded daily = R %

The Amount at the end up = $ 114,000

<u>From compounded method</u>

Amount = Principal × (1+\dfrac{rate}{365\times 100})^{365\times Time}

Or, $ 114,000 = $ 98,000  × (1+\dfrac{R}{365\times 100})^{365\times 7}

Or, \frac{114000}{98000} = (1+\dfrac{R}{36500})^{2555}

or, 1.16326 = (1+\dfrac{R}{36500})^{2555}

or, (1.16326)^{\frac{1}{2555}} = 1 + \frac{R}{36500}

1.00005919 - 1 =  \frac{R}{36500}

or, 0.00005919 =  \frac{R}{36500}

∴ R =  0.00005919 × 365000 = 2.16

Hence the rate of interest for compounded daily is 2.1 6   Answer

Solve the system by graphing.
igor_vitrenko [27]

Answer:

Hi There the correct answer is {x,y} = {-1,-10}  

 

System of Linear Equations entered :

  [1]    3x - y = 7

  [2]    4x - 2y = 16

Graphic Representation of the Equations :

   y + 3x = 7        -2y + 4x = 16  

 

 

Solve by Substitution :

// Solve equation [1] for the variable  y  

 

 [1]    y = 3x - 7

// Plug this in for variable  y  in equation [2]

  [2]    4x - 2•(3x-7) = 16

  [2]    -2x = 2

// Solve equation [2] for the variable  x  

  [2]    2x = - 2  

  [2]    x = - 1  

// By now we know this much :

   x = -1

   y = 3x-7

// Use the  x  value to solve for  y  

   y = 3(-1)-7 = -10  

Solution :

{x,y} = {-1,-10}  

Hope it helps!
