How much is the interest on my loan?
kirill [66]

Answer:  The interest is:  " $ 64 .00 " .

_____________

Step-by-step explanation:

_____________

Take note of the formula:

" Ⅰ = Prt " ;

→ that is:

_____________

→   " Ⅰ = P * r * t " ;

_____________

In which:  

_____________

 " Ⅰ = the interest " ;

 " P = the Principal amount of money " ;

 " r = rate " (expressed as the "decimal form" of the percentage) ;

 " t = time " (in years) ;

_____________

We are given:  

_____________

 P = $400 ;

 r = 0.08 ;  

{<u>Note of interest</u>:  That is " 8% " ; since "8 % "  = "(8/100)" ;

                                                                          = "(8 ÷ 100)"

                                                                          = " 0.08 ".}.

 t = 2 ; {that would represent:  " 2 (two) years".}.

_____________

We are to solve for "Ⅰ" ; the amount of "Ⅰnterest" :

→ To solve for "Ⅰ " ; we plug in our given values; and calculate:

_____________

  →  Ⅰ = P * r * t ;

        = 400 * 0.08 * 2 ;

        = 64 .

_____________

  →  Ⅰ = $ 64.00 .

_____________

Hope this is helpful to you!

Best wishes!

Solve: e^2x + 5 = 4<br> help pls
kaheart [24]

Answer:

The solution of the equation is x=\frac{(ln4)-5}{2} ⇒ 3rd answer

Step-by-step explanation:

* Lets explain how to solve this problem

- The function f(x) = e^x is called the (natural) exponential function

- The natural logarithm (㏑), or logarithm to base e, is the inverse

 function to the natural exponential function

∵ e^{2x+5}=4 is an exponential function

∴ We can solve it by using the inverse of e (㏑)

- Remember:

# ln(e)=1

# ln(e^{m})=m(ln(e))=m

- Insert ln in both sides

∴ ln(e^{2x+5})=ln(4)

∵ ln(e^{2x+5})=(2x+5)ln(e)=2x+5

∴ 2x + 5 = ㏑(4)

- Subtract 5 from both sides

∴ 2x = ㏑(4) - 5

- Divide both sides by 2 to find x

∴ x=\frac{ln(4)-5}{2}

* The solution of the equation is x=\frac{(ln4)-5}{2}
