if the annual interest rate is 6%, and interest is compounded monthly, the interest rate per period is: %
for a 4-year loan, at 8% compounded quarterly, the number of interest periods is:

1) 0.5 %

2) 16

Step-by-step explanation:

Since, a year = 12 months,

1 month = year,

1) If the interest is compounded monthly,

Then, the rate per period =  

Given, annual rate = 6%,

So, the rate per period = = 0.5%,

2) 1 year = 4 quarters,

If the loan is of 4 year and it is compounded quarterly,

Then, the number of compounding periods = number of years × 4

= 4 × 4

= 16

if the eqn of the parabola is f(x) = (x-4)(x+2), we need to mult. this out to find the coordinates of the vertex.

then f(x) = x^2 + 2x - 4x - 8, and f(x) = x^2 - 2x - 8.

one way in which you can find the vertex is to calculate x = -b / (2a).   here, that comes to

        )

x = = 1.   f(1) = 1^2 - 2(1) - 8 = - 9.   vertex is at (1, -9).

        2(1) 

find another point on the curve:   let x=0, for which y=-8.   then (0, -8) is on the curve.   plot the vertex and this point and draw a smooth parabola thru both.

hello from mrbilldoesmath!

answer:

the domain is the set { -2, 0, 2, 3}

discussion:

the domain is the set of x values in the ordered pairs (x,y). taking the x, or first component, of each ordered pair gives   -2, 0, 2, 3.
