Answer:
$148.02
Step-by-step explanation:
In the question
Principal = $100, rate(R) = 4% compounded annually, time(T)= 10 years
we know that the formula for compound interest
A= where A is amount
now putting values in the above formula we get
A=
therefore A= $148.024428
rounding off to the nearest penny we get amount as $148.02 and compound interest will be $48.02
Step-by-step explanation:
We need to write the function that have two real number zeros by calculating the discriminant i.e. .
We know that,
If D>0 the roots are real and unequal
If D= 0 roots are real and equal
If D< 0 roots are imaginary or not real and unequal
Function (1)
D>0 the roots are real and unequal
Function (2)
D<0 the roots are real and unequal
Function (3)
D>0 the roots are real and unequal
Function (4)
D>0 the roots are real and unequal
Function (5)
D<0 the roots are real and unequal
Function (6)
D>0 the roots are real and unequal
(1),(3),(4) and (6) have two real number zeroes.
