Assume the cost of a car is $25,000. With continuous compounding, in effect, the cost of the care will increase according to the
Masja [62]
The value of t that makes the factor e^(.032t) have the value of 2 can be found using logarithms.
  2 = e^(0.032t)
  ln(2) = ln(e^(0.032t)) = 0.032t
  t = ln(2)/0.032 ≈ 21.66

It would take 21.66 years for the cost to double.

Solve the equation 2(9x-6)=6(3x-2)+2
weqwewe [10]

Answer:

There are no solutions.

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

2(9x−6)=6(3x−2)+2

(2)(9x)+(2)(−6)=(6)(3x)+(6)(−2)+2(Distribute)

18x+−12=18x+−12+2

18x−12=(18x)+(−12+2)(Combine Like Terms)

18x−12=18x+−10

18x−12=18x−10

Step 2: Subtract 18x from both sides.

18x−12−18x=18x−10−18x

−12=−10

Step 3: Add 12 to both sides.

−12+12=−10+12

0=2

Audrey is buying a new car for 32,998.00. She plans to make a down payment of 4,200.00. If she's to make a monthly payments of 5
UkoKoshka [18]

<span>This question is an annuity problem with cost of the car = $32,998, the present value of the annuity (PV) is given by the difference between the cost of the car and the down payment = $32,998 - $4,200 = $28,798. The monthly payments (P) = $525 and the number of number of years (n) = 5 years and the number of payments in a year (t) is 12 payments (i.e. monthly) The formula for the present value of an annuity is given by PV = (1 - (1 + r/t)^-nt) / (r/t) 28798 = 525(1 - (1 + r/12)^-(5 x 12)) / (r/12) 28798r / 12 = 525(1 - (1 + r/12)^-60) 28798r / (12 x 525) = 1 - (1 + r/12)^-60 2057r / 450 = 1 - (1 + r/12)^-60 Substituting option A (r = 37% = 0.37) 2057r / 450 = 2057(0.37) / 450 = 761.09 / 450 = 1.691 1 - (1 + r/12)^60 = 1 - (1 + 0.37/12)^-60 = 1 - 0.1617 = 0.8383 Therefore, r is not 37% Substituting option D (r = 3.7% = 0.037) 2057r / 450 = 2057(0.037) / 450 = 76.109 / 450 = 0.1691 1 - (1 + r/12)^60 = 1 - (1 + 0.037/12)^-60 = 1 - 0.8313 = 0.1687 Therefore, r is approximately 3.7%</span>
