Morgan has an investment worth $30,000 dollars invested at 5% simple
interest. If no withdrawals or deposits were made, what is the balance
after 20 years?
O
$50,000
O
$45.000
$60,000
O
$80,000

in 20 years there would be 60,000                                      

Step-by-step explanation:

So there is $3655.21 in the account after 4 years (where $3000 is invested at an interest rate of 5% each year and it's compounded semiannually).

it is the one with 60,000

Step-by-step explanation:

the polynomial is a perfect square trinomial of the form a^2-2ab+b^2:

option a. true

step-by-step explanation:

9x^2-12x+4

comparing with the form a^2-2ab+b^2

1.) a^2=9x^2

solving for a: square root both sides of the equation:

sqrt(a^2)=sqrt(9x^2)

a=sqrt(9) sqrt(x^2)

a=3x

2.) b^2=4

solving for b: square root both sides of the equation:

sqrt(b^2)=sqrt(4)

b=2

to be a perfet square trinomial 2ab must be equal to 12x. let's check:

2ab = 2 (3x) (2)

2ab = 12x

correct
