Mathematics
1 answer:
Bad White [126]3 years ago
5 0

Answer:

(x+3)(x-3) = x²-9

(a+4)(a-4) = a²-16

(2/3x²y+1/4)(2/3x²y-1/4) = ((4x^4)y²)/9-1/16

(2x²+3y³)(2x²-3y³) = 4x^4-9y^6

(b-2)(b-2)(b-2) = b³-6b²+12b-8

Step-by-step explanation:

(x+3)(x-3) = x²-9

(a+4)(a-4) = a²-16

(2/3x²y+1/4)(2/3x²y-1/4) = ((4x^4)y²)/9-1/16

(2x²+3y³)(2x²-3y³) = 4x^4-9y^6

(b-2)(b-2)(b-2) = b³-6b²+12b-8

If a person wants to have $2000 after 4 years, how much would they have to deposit into an account that pays 6.5% interest compo
V125BC [204]

Answer:

The amount is $2572.93 and the interest is $572.93.

Step-by-step explanation:

STEP 1: To find amount we use formula:

A=P(1+rn)n⋅t

A = total amount  

P = principal or amount of money deposited,

r = annual interest rate  

n = number of times compounded per year

t = time in years

In this example we have

P=$2000 , r=6.5% , n=1 and t=4 years

After plugging the given information we have

AAAA=2000(1+0.0651)1⋅4=2000⋅1.0654=2000⋅1.286466=2572.93

STEP 2: To find interest we use formula A=P+I, since A=2572.93 and P = 2000 we have:

A2572.93II=P+I=2000+I=2572.93−2000=572.93
