Answer:
The degree of the polynomial is 4.
Step-by-step explanation:
Given:
Polynomial =
To Find:
The degree of the polynomial = ?
Solution:
The degree of the polynomial is the highest degree in the polynomial expression.
Here, the degrees are 4, 2, 1
and the coefficients are 7 , 5 , 1
and the constant term is -9
The Highest among the degrees is 4

Answer:
The value of this investment at the end of the 5 years is of $662.5.
Step-by-step explanation:
Compound interest:
The compound interest formula is given by:
Where A(t) is the amount of money after t years, P is the principal(the initial sum of money), r is the interest rate(as a decimal value), n is the number of times that interest is compounded per year and t is the time in years for which the money is invested or borrowed.
Dina invests $600 for 5 years at a rate of 2% per year compound interest.
This means that . Thus
Calculate the value of this investment at the end of the 5 years.
This is A(5). So
The value of this investment at the end of the 5 years is of $662.5.
