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.
Answer:
An expression will be said to be a perfect square trinomial if it takes the form of ax² + bx + c and if it satisfies the condition b² = 4ac.
Step-by-step explanation:
An expression which is obtained from the square of a binomial equation is known as perfect square trinomial.
Now, the conditions for which an equation will be called a perfect square trinomial are;
i) It is of the form: ax² + bx + c
I) It satisfies the condition: b² = 4ac.
Thus, the perfect square formula could take the following forms:
(ax)² + 2abx + b² = (ax + b)²
Or
(ax)² − 2abx + b² = (ax − b)²
Loan + interest= 450+ (9.9%•450)= 494.55
Monthly payment= 494.55/12=41.21
Answer is (2)
Given:
There are given that the polynomial:
Explanation:
According to the concept, trinomial is three terms, and binomial means two terms.
And,
When the degree of any polynomial is 2, then it represents quadratic, when the degree is 3, it represents cubic, when the degree is 4, then it represents quartic, and when the degree is 5, then it represents quintic.
Now,
From the equation:
In the above equation, there are only two parts and they have degree 4.
So, the given terms represent quartic binomial.
Final answer:
Hence, the correct option is C.
