Answer:
A.
B.
Step-by-step explanation:
Given that:
An investment of Amount = $8000
earns at an annual rate of interest = 7% = 0.07 compounded continuously
The objective is to :
A) Find the instantaneous rate of change of the amount in the account after 2 year(s).
we all know that:
where;
The instantaneous rate of change =
At t = 2 years; the instantaneous rate of change is:
(B) Find the instantaneous rate of change of the amount in the account at the time the amount is equal to $12,000.
Here the amount = 12000
㏑(1.5) = 0.07 t
0.405465 = 0.07 t
t = 0.405465 /0.07
t = 5.79
At t = 5.79
Answer:
z^2/z=z
Step-by-step explanation:
Answer:
3.2 is the highest value for k that will yield a non-negative discriminant
Step-by-step explanation:
For an equation to have real numbers as solutions, its discriminant (delta value) must be bigger than zero since there are no real square root solutions for negative numbers.
In this case, the discriminant is given by:
For k =3.2
As shown above, 3.2 is the highest value for k that will yield a non-negative discriminant and, therefore, if k > 3.2 the solutions of the expression are not real numbers.
D. Because a number is irrational if it doesn't terminate or if it repeats over and over
50 miles since 1 inch equals 10 miles and there's 5 inches that means 5x10=50
