You are opening a savings account with $500 that you have saved. The bank offers 3.2% interest, compounded yearly. How much mone
Nuetrik [128]

Answer:

You will have $623.3441462 in your account after 7 years

Step-by-step explanation:

The formula of the compounded interest is A = P (1+\frac{r}{n})^{nt} , where

  • A is the new value
  • P is the initial value
  • r is the rate in decimal
  • n is the number of periods
  • t is the time in years

∵ You are opening a savings account with $500  

∴ P = 500

∵ The bank offers 3.2% interest, compounded yearly

∴ r = 3.2% ⇒ divide it by 100 to change it to decimal

∴ r = 3.2 ÷ 100 = 0.032

∵ The interest is compounded yearly

∴ n = 1

∵ The time is 7 years

∴ t = 7

→ Substitute these values in the rule above to find A

∵ A = 500 (1+\frac{0.032}{1})^{1(7)}

∴ A = 500 (1.032)^{7}

∴ A = 623.3441462

∴ You will have $623.3441462 in your account after 7 years

sweet [91]

Answer:

part a and b only i was actually looking for c

Step-by-step explanation:

for part b

Area of DEF= 1/2× base × height = 1/2× 2 × 1 = 1

Area of FGD= 1/2× base × height = 1/2× 2.24 × 1.34 =1.50  

Area of GBD= 1/2× base × height = 1/2× 2 × 1 = 1

Area of ABG= 1/2× base × height = 1/2× 4.12 × 0.49 =1.01

Area of BCD= 1/2× base × height = 1/2× 1.41 × 2.12 =1.49

The approximate area of the original polygon is 6 square units
