Answer:
96
Step-by-step explanation:
24+20+24+20+4+4=96
"A parabola is curved instead of linear, in your case it is probably just facing up or down so I won't get into square roots for now.So the quadratic equation that you probably have had to memorize (or will soon) is:
x=(-b[+or-]√(b²-4ac))/2a when you have an equation like ax²+bx+c=0Now where does the curve shape come from? You see that little pesky plus or minus in the equation? That's because there are always 2 values (inputs) that will generate the same output. Example:y=x²(2)²=4(-2)²=...4So if you were to follow this pattern, and plot the points on a graph, you would end up with a curve. You end up with a curve because the slope is constantly increasing.
And this is actually where you start the study of Calculus(!), which is all about measuring slopes (And a bunch of other stuff, but this is the easiest part to explain). Actually, in this case of y=x², the slope at any given point (funnily enough) is equal to 2 times your x-value.
The point is, your line is curved because unlike a linear equation, the slope is changing (at a constant rate)."
Answer:
2.25
Step-by-step explanation:
The value of point C is already positive, so nothing changes.
_____
The absolute value function changes negative numbers to positive ones (by multiplying by -1, or reflecting across the origin of the number line).
<u>Given</u>:
Line segment DM with end points D(-4,5) and M(6,0) is reflected about the x - axis to give line segment D'M'.
We need to determine the coordinates of the point D'.
<u>Coordinates of the point D':</u>
The general to reflect the coordinates over the x - axis is given by
To determine the coordinates of the point D', let us substitute the coordinates of the point D in the above rule.
Thus, we get;
The reflection of the coordinate D(-4,5) about the x - axis to give the point D' is (-4,-5)
Thus, the coordinates of the point D' is (-4,-5)
Ok first you divide -1/2 by -8 which equals your answer
