A bank account has an initial deposit of $14,000. After 8 years, the bank accounthas $18,000. Assuming that compounding interest is done annually and that no
withdrawals are taken, find the annual interest rate on the investment. If the interest is compounded annually what is the approximate interest rate on the investment?

Answers

Answer 1
Answer:

Answer:

2.3%

Step-by-step explanation:

18000 = 15000( 1 + i)^8

Divide both sides by 15000

1.2 = (1 + i)^8

Take both sides to the 1/8 power

1.2^(1/8) = 1 + i

1.023051875220463 = 1 + i

Subtract 1 from both sides

i = 0.023051875220463

~ 2.3%

What is the solution to the equation -(5-(a+1))=9-(5-(2a-3))

Answers

Answer:

a)-5

Step-by-step explanation:

-(5-(a+1))=9-(5-(2a-3))

=    -(5-a-1)= 9-(5-2a+3)

=    -5+a+1 = 9-5+2a-3

=     -4+a = 1+2a

=     -4 - 1 = 2a-a

=     -5 = a
Step 1: Simplify both sides of the equation.
−(5−(a+1))=9−(5−(2a−3))
−(5−(a+1))=9+−1(5−(2a−3))(Distribute the Negative Sign)−(5−(a+1))=9+(−1)(5)+−1(−2a)+(−1)(3)−(5−(a+1))=9+−5+2a+−3a+−4=9+−5+2a+−3(Distribute)a−4=(2a)+(9+−5+−3)(Combine Like Terms)a−4=2a+1a−4=2a+1Step 2: Subtract 2a from both sides.a−4−2a=2a+1−2a−a−4=1Step 3: Add 4 to both sides.−a−4+4=1+4−a=5Step 4: Divide both sides by -1.−a−1=5−1a=−5
