Answer:
Final amount = 25,407.4
Step-by-step explanation:
A = P ( 1 + 
A = final amount
P = initial principal balance
r = interest rate
t = number of times interest applied per time period
Here P = 2000
r = 4 %
n = 3 years
A = 2000( 1 + 
)³
= 2000( 
)³
= 2000 × 
= 25,407 .4
Final amount = 25,407.4

Answer:
(2x-3) (2x+3)
zeros, x intercepts: -3/2, 3/2
Step-by-step explanation:
4x^2 -9
We know the difference of squares is a^2 -b^2
This factors into (a-b) (a+b)
Let 4x^2 =a^2
Taking the square root
2x =a
Let b^2 =9
Taking the square root
b= 3
(4x^2-9 ) = (2x-3) (2x+3)
To find the zeros, we set the equation equal to zero
(4x^2-9 ) = (2x-3) (2x+3) =0
Using the zero product property
2x-3 =0 and 2x+3 =0
2x-3+3 = 0+3 2x+3-3 = 0-3
2x=3 2x=-3
Divide by 2
2x/2 = 3/2 2x/2 = -3/2
x = 3/2 x = -3/2
These are the zeros of the equation (which are also the x intercepts)
3xy -6x
just multiply 3x by y and 3x by -2
(10 pounds) - (7 pounds 3 ounces) =
2.8125 pounds
