C. Compound daily applies interest everyday over a period of 365 days in a year. Compound annually only applies the 3% interest once a year.
Step-by-step explanation:
3% compounded daily:
A = P(1 + r/n)^nt
= 25000(1 + )^365(5)
= 25000(1.00008219)¹⁸²⁵
= 25000(1.161827)
= 29045.6770
3% compounded annually:
A = P(1 + r/n)^nt
= 25000(1 + )^1(5)
= 25000(1.03)⁵
= 25000(1.159274)
= 28981.8518
Answer: The equation of parabola is .
Explanation:
It is given that the focus of the parabola is (−5, 5) and a directrix of y = −1.
The standard form of a parabola is,
Where, (h,k+p) is the focus and y=k-p is the directrix.
It is given that the focus of the parabola is (−5, 5).
On comparing both sides we get,
.... (1)
The directrix of y = −1.
.... (2)
Add equation (1) and (2),
Put this in equation (1),
Put p=3, k=2 and h=-5 in standard equation of parabola.
Therefore, the equation of parabola is .
