Jari invests in a CD with an annual interest rate of 6.90% compounded quarterly. How many years will it take for Jari's investme
ivann1987 [24]

Answer:   10.1246 years (approx)

Step-by-step explanation:

Here, She invests in a CD with an annual interest rate of 6.90% compounded quarterly.

Let the initial amount or principal = P

And, Let after t years it is doubled.

Therefore, 2P= P(1+\frac{6.9}{400} )^{4t}

⇒ 2 = (1+\frac{6.9}{400} )^{4t}

⇒log 2 = t log(1+\frac{6.9}{400} )^4 ( By taking log both sides)

⇒log 2 = t log(1.01725 )^4

⇒t= log 2/log 1.07080599536= 10.1245504311≈10.1246 years

What is the equation of a line that passes through the point (0, -2) and has a slope of -3? y = -3 y = -3x - 2 y = -2x - 3 y = -
goblinko [34]
The general equation of a line is y = mx +b. 
m is equal to the slope, so for this problem it is m = -3 
b is equal to the y-intercept (the y-point when x = 0) so according to this since it passes through (0, -2), x=0 at y = -2 
The equation of the line is: y = -3x - 2
