Recall that to compute for the new amount of the original sum at a compound interest is
A(t) = P(1 + r/n)^(nt)
where P is the original amount, r is the interest rate, n is the number of times P is compounded each year, and t is the number of year.
With this, the total amount owed by Sam in five full years becomes [(120)(1 + 0.30/12)^60 ]. The total interest is the difference between the original amount owed and the amount that needs to be paid over time. Thus, total interest is [(120)(1 + 0.30/12)^60 ] - 120 = 407.97.
Therefore, the total interest is $407.97<span>.</span>
Answer:
Consider: (a+b)(a-b)=a^2-ab+ab-b^2=a^2-b^2. This is a binomial. Hence, it is not always true that the product of two binomials is a trinomial.
Step-by-step explanation:
Let y = daily rate
let x = number of people
let m = charge per person
let b = arbitrary cost
so, y=mx+b
150 = 20m + b
330 = 50m + b
30m = 180
m = 6
b = 30
so linear relationship : y = 6x+30
if x = 30
y = 180 + 30
y = 210
Answer:
1. f(1) = -1
2. for x=3 f(x)=1
Step-by-step explanation:
According to function definition:
for x=1 f(x)=f(1)=-1 (for first answer)
for x=3 f(x)=f(3)=1 (for second answer)
E, D, and A.
well because it can be divide my 5.
