Find the final amount for a $750 investment at 5.25% interest compound semiannually for 25 years
Rufina [12.5K]

Answer:

=$2739.81

Step-by-step explanation:

To find the total amount if the interest is compounded, we use the compound interest formula.

A=P(1+R/100)ⁿ

A is the amount, P- principal, is the invested amount R is the % interest rate, n is the number if periods.

If compounded semi-annually, it means we have two periods in 1 year

The rate is also divided by 2

Thus 25 years have (25×2) = 50 periods.

A= 750(1+5.25/200)⁵⁰

=750(1.02625)⁵⁰

=$2739.81

Can someone please help me coz i really need this :(<br><br>i need serious answer :(​
sp2606 [1]

Answer:

1. DB = 10 as diagonals of isosceles trapezoid are congruent

2. ∠DAB and ∠BCD are supplementary angles

  • m∠BCD = 180° - 120° = 60°

3. ∠BCD is congruent with ∠ADC as trapezoid is isosceles

  • m∠BCD = m ∠ADC = 65°

4. AB = 15, DC = 25,

  • EB = 1/2(AB + DC) as midline
  • EB = 1/2(15 + 25) = 20

5. m∠ADC = 2x - 10, m∠ABC = 3x + 40

<u>These are supplementary, find x first:</u>

  • 2x - 10 + 3x + 40 = 180
  • 5x + 30 = 180
  • 5x = 150
  • x = 30
  • m∠BCD = m∠ADC = 2*30 - 10 = 50°
