Answer:
When graphing a linear inequality on a number line, use an open circle for <em><u>"less than" or "greater than",</u></em> and a closed circle for "less than or equal to" or "greater than or equal to".
Answer:
f(1) = -3 f(n) = 2 f(n - 1) + 1 f(2)
Alternate form:
{f(n) = -f(1)/3, f(n - 1) = f(1)/2 - f(2)/2}
Answer:
0.16666666666
Step-by-step explanation:
2400 divided by 44% which is 1056.
(sneaky way to put history in math, btw...)
As far as I can make out this one.
the bunker is a 3D object, it has a height, with and length, however we're only concerned with the 2D front face, which has a length and width only.
we know the x-axis is the ground level, so the y-axis must be the scale for the length.
if we can find, using the provided model, the x-intercepts, namely where the x-axis gets touched, we can just get the distance between them and that's the ground level width.
keeping in mind that when the graph touches the x-axis, an x-intercept, "y" is 0.

now, the distance from (-72, 0) and (72, 0) is just 72 +72, or 144.
