Which number is equal to 10 tens + 5 ones + 3 tenths + 6 thousandth

63,105

Step-by-step explanation:

15.306

Step-by-step explanation:

I'm not sure if this is correct, but it should be. 10 + 5 would be 15, and you put "tens" and "ones" without the "th", then you would put a decimal and put 3 for the tenths, 0 since there is no number stated for the hundreths, and 6 for the thousandth.

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.

hope this
