How many years (to two decimal places) will it take $15000 to grow to $17500 if it is invested at 8% compounded semi- annually?
VLD [36.1K]

Answer:

1.97 years

Step-by-step explanation:

First, convert R as a percent to r as a decimal

r = R/100

r = 8/100

r = 0.08 per year,

Then, solve the equation for t

t = ln(A/P) / n[ln(1 + r/n)]

t = ln(17,500.00/15,000.00) / ( 2 × [ln(1 + 0.08/2)] )

t = ln(17,500.00/15,000.00) / ( 2 × [ln(1 + 0.04)] )

t = 1.965 years

1. the shape is a parallelogram. what is the measure of KL?
aleksklad [387]

Answer:

1. KL = 29

2. angle J = 127 degree

3. angle of K = 53 degrees

Step-by-step explanation:

SInce it is a parrallelograme, one thing that will help you is to remember that opposits are the same.

1. KL = JM since they are opposite => KL = 29

2. angle J = angle L since they are opposite => angle J = 127 degrees

3. Since we know that angle J and L are both equal to 127 degree and since the sum of the angles of a parralelogram is 360 degrees, so the sum of the angles of K and M is:  360 - 127 - 127 = 106 degrees.

Since K's and M's angles are equale => 106 / 2 = 53 degrees.
