6 0

Answer:

<em>Value of x = 25</em>

Step-by-Step Explanation:

~ Knowing that, in a right triangle ~

sin(40-x)=cos(3x) ⇒

sin(40-x)=sin(90-3x) ⇒

40 - x = 90 - 3x ⇒

40 - x  +3x=90 - 3x  +3x =>

40+2x=90 =>

2x=50 =>

x = 25

<em>Now it is proven to be that,</em>

<em>x = 25</em>

You decide to put $175 in a savings account to save for a $3,000 down payment on a new car. If the account has an interest rate
KengaRu [80]
First, determine the annual effective interest based on the annual interest and the compounding,
                                ieff = (1 + i/m)^m - 1
Substituting,
                       ieff = (1 + 0.03/12)^12 - 1 = 0.0304
To determine the future worth (F) of the current investment (P) is,
                                    F = P(1+ieff)^n
Substituting all the known values with n unknown,
                               3000 = 175(1 + 0.0304)^n
Solving for n gives an n = 94.8867 years
Among the choices, the nearest value is 94.8377 years.
