after 2 years?
symbol required

The total balance of his account after 2 years=$581.875

Step-by-step explanation:

The formula for calculating the compound interest is given as;

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

where;

A=Total amount after a given period of time

P=Initial deposit

r=annual Interest rate

n=number of times the interest is compounded annually

t=number of years the deposit is in the account

In our case;

P=$190

r=75%=75/100=0.75

n=1

t=2 years

Replacing;

A=190(1+0.75/1)^(1×2)

A=190(1.75)^2

A=190×3.0625

A=$581.875

The total balance of his account after 2 years=$581.875

-7

step-by-step explanation:

x^2 + 18x + 74 = (x + 9)^2 - 81 + 74

= (x + 9)^2 - 7.

so q = -7.
