62 +510 + 10 = 572
572 ÷ 2 = 286.
Answer:

Step-by-step explanation:
Given

Required
Determine the domain of the function
To do this, we need to solve for the vertex, p of the function

Given the the general form of a quadratic function is:

By comparison, we have:

So:




Substitute 1 for p in 



This implies that

The interpretation of this is that;
<em>For every value of p, there's a corresponding value of R.</em>
<em>However, because p indicates price and it's impossible to have a negative price, we can say that the minimum value of p is 0;</em>
Hence, the domain is

x is 14.3

the right angle is 90 degrees, so sin(a) is 90

multiply sin(90) on both sides to give:

x is 14.3
The distance between any two points can be calculated using Pythagorean Theorem...
d^2=(x2-x1)^2+(y2-y1)^2
d^2=(-14-10)^2+(-3--3)^2
d^2=24^2+0
d=24 units...
You could do that (
yes), but in many cases, you would need to determine equivalence some other way (
no) before plotting the numbers on a number line.
If the number line is graduated in a manner that makes 1/2 clear, and also makes 4/8 clear, then it is possible to determine that both values lie at the same point. If the number line is graduated in tenths or hundredths (for example), you would need to convert both numbers to that format before plotting.
