Which quadratic equation defines the function that has zeros at -8 and 6?

1 answer:

5 0

Well, if 'y' has zeros at x=6 and x=-8,
then 'y' must be the product

y = (x - 6) (x + 8)

Perform the multiplication to get the quadratic function:

y = x² + 2x - 48

Answer:

Calculate the Macaulay duration of Annuity B at the time of purchase is 1.369.

Step-by-step explanation:

First, we use 0.93 to calculate the v which equals 1/(1+i).

$\frac{0+1*v+2v^{2} }{1+v+v^{2} }$ = 0.93

After rearranging the equation, we get 1.07 $v^{2}$ + 0.07v - 0.93=0

So, v=0.9

Mac D: $\frac{0+1*v+2*v^{2}+ 3*v^{2} }{1+v+v^{2}+ v^{3} }$

After substituting the value of v, we get Mac D = 1.369.
