Let point A(x,y) be the point on the x-axis. All points that lie on the x-axis have y-coordinate equal to 0, then A(x,y).
Find the distance from point A to point (12,-5):
![d=\sqrt{(x-12)^2+(0-(-5))^2}=\sqrt{(x-12)^2+25}.](https://tex.z-dn.net/?f=d%3D%5Csqrt%7B%28x-12%29%5E2%2B%280-%28-5%29%29%5E2%7D%3D%5Csqrt%7B%28x-12%29%5E2%2B25%7D.)
This distance is equal to 13, then
![\sqrt{(x-12)^2+25}=13,\\ \\(x-12)^2=169-25,\\ \\(x-12)^2=144,\\ \\x-12=12 \text{ or } x-12=-12,\\ \\ x=24 \text{ or }x=0.](https://tex.z-dn.net/?f=%5Csqrt%7B%28x-12%29%5E2%2B25%7D%3D13%2C%5C%5C%20%5C%5C%28x-12%29%5E2%3D169-25%2C%5C%5C%20%5C%5C%28x-12%29%5E2%3D144%2C%5C%5C%20%5C%5Cx-12%3D12%20%5Ctext%7B%20or%20%7D%20x-12%3D-12%2C%5C%5C%20%5C%5C%20x%3D24%20%5Ctext%7B%20or%20%7Dx%3D0.)
You get two ponts (0,0) and (24,0).

Answer:
y=a(x^2-5x+4)
Step-by-step explanation:
I mean there are a bunch of answers. to figure it out, you can use the formula where you have solved the zeroes in terms of x.
y=(x-1)(x-4)
y=x^2-5x+4
Now if you add any a value to this function, your function will stretch or compress accordingly
y=a(x^2-5x+4)
So there isn't a single correct answer, but if you're looking for a bunch, then just replace the a value with whatever value you want, you'll still get the same answer since they're all proportional to one another.

Answer:
All of the batches of the new blend of concrete made at their plant in a particular week.
Step-by-step explanation:
The population refers to all the subjects or data which which meets the condition or requirement of a certain experiment or research. This means that all the set of similar items or subjects which is of interest in a certain study is the population. In the scenario above, the population will be the set of all the new blend concrete which are made in the plant within a certain week. Thereafter, if a sample is required it will be drawn from these set of data or observation.
