So you have: ((-15(x^2)(y^6))+(50(x^4)(y^3))+(20x^2y))/((5x^2)(y))

which simplifies to

(-3y^5)+(10(x^2)(y^2))+4

as there are no like terms and x and y have not been given, this is as far as it can be simplified.

qaws [65]

Answer:

the interest earned= 93.401

and the future value of an annuity= 493.401

Step-by-step explanation:

Given Data:

Interest rate= 7%

time,t = 3 years

weekly payment, P= 400

At the end of 3 years, final investment A= ?

n= 52 as it is weekly

As per the interest formula

A= P(1+r/n)^nt

Putting value in above equation

= 400\left(1+\frac{0.07}{52}\right)^{156}

= 493.401

Interest earned = A-P

                           = 493.401-400

                          = 93.401 !
