Answer: the initial deposit is $162.1

Step-by-step explanation:

The formula for continuously compounded interest is

A = P x e (r x t)

Where

A represents the future value of the investment after t years.

P represents the present value or initial amount invested

r represents the interest rate

t represents the time in years for which the investment was made.

e is the mathematical constant approximated as 2.7183.

From the information given,

r = 7% = 7/100 = 0.07

t = 3 years

A= $200

Therefore,

200 = P x 2.7183^(0.07 x 3)

200 = P x 1.234

P = 200/1.234

P = $162.1 to the nearest cent

 x = (180/100) * (23000)
 x = 41400

The bes thing to do t find the scale factor is to divide the larger number by the smaller number. 260/13= 20 120/6= 20. As these are both the same, therefore, the scale factor is 20. Hope this helps :)

Answer:

  y = -4/3x +2

Step-by-step explanation:

The slope-intercept form of the equation of a line with slope m and y-intercept b is ...

  y = mx + b

To get your equation with slope -4/3 and y-intercept 2, you put -4/3 where m is, and 2 where b is.

  y = -4/3x + 2
