For the given bond, whose interest rate is provided, find the semiannual interest payment and the
Vika [28.1K]

Answer:

The semiannual interest payment is $485.5

The total interest earned over the life of the bond is $10,681

Step-by-step explanation:

The formula of the simple interest is I = Prt, where

  • P is the money invested
  • r is the interest rate in decimal
  • t is the time in years

∵ The bond is $20,000

∴ P = 20,000

∵ First Income Fund 11-year bond at 4.855%

∴ t = 11

∴ r = 4.855%

- Change it to decimal by divide it by 100

∴ r = 4.855 ÷ 100 = 0.04855

∵ The semiannual interest payment = P × r × half a year

∴ The semiannual interest payment = 20,000 × 0.04855 × \frac{1}{2} (1)

∴ The semiannual interest payment = 485.5

The semiannual interest payment is $485.5

∵ I = Prt

- Substitute the values of P, r and t in the formula

∴ I = 20,000(0.04855)(11)

∴ I = 10,681

The total interest earned over the life of the bond is $10,681

The endpoints of ab are a(1,4) and b(6,-1). If point c divides ab in the ratio 2:3, the coordinates of c are ?. If point d divid
aliya0001 [1]

Answer:

see explanation

Step-by-step explanation:

Find the coordinates of c using the section formula

x_{c} = \frac{(3(1)+(2(6)}{2+3} = \frac{3+12}{5} = 3

y_{c} = \frac{(3(4))+(2(-1))}{2+3} = \frac{12-2}{5} = 2

coordinates of c = (3, 2)

Similarly to find the coordinates of d

x_{d} = \frac{x(2(1))+(3(3))}{3+2} = \frac{2+9}{5} = \frac{11}{5}

y_{d} = \frac{(2(4))+(3(2))}{3+2} = \frac{8+6}{5} = \frac{14}{5}

coordinates of d = ( \frac{11}{5}, \frac{14}{5})
