Answer:
Step-by-step explanation:
Vertex-form equation for vertical parabola:
y = a(x-h)² + k
with
vertex (h,k)
axis of symmetry: x = h
Apply your equation
y = 3x² + 18
vertex (0,18)
axis of symmetry: x = 0
The future value of a monthly deposit A=125.30 at annual interest i=0.015 per annum for n=35 years compounded monthly is given by
FV=A((1+i/12)^(12*n)-1)/(i/12)
=125.30(1+0.015/12)^(12*35)/(0.015/12)
=$69156.05
The annuity formula is given by
Payment = r(PV)/(1-(1+r)^(-n))
where
r=interest rate per period = 0.015/12
PV= $69156.05
n=20*12=240
so
Payment = (0.015/12)<span>69156.05/(1-(1+0.015/12)^(-240))
= $333.71 per month.</span>
Break the number apart into hundreds, tens, ones, etc. and add the quantities together. Here is an example:
<em>To write 256 in expanded form, break it apart. There is 200, 50, and 6 in 250. Now, add them together. 200 + 50 + 6 = 256</em>
x- the number
9x - 4
Four less (-4) than nine times number (9x)
x/4 + 9
Nine more (+9) than one-fourth of number (1/4 x = x/4)
4 - 9x
Four (4) decreased (-) by the product of a number and nine
4x - 9
Nine less (-9) than a four times number (4x)
x/9 + 4
The sum (+) of one-nineth a number (1/9 x = x/9) and four (4)
