Answer: Graph a straight line through (4,0) and (4,1)

These two points have the same x coordinate x = 4. The y coordinate doesn't matter. All points on this vertical line have the same x coordinate.

Extra info: All vertical lines have an undefined slope.

The portion of a student’s ballpoint pen that contains the ink is a cylinder with a diameter of 0.400 cm and a height of 11.5 cm

grandymaker [24]

First, we need to figure out the volume of the cylinder that holds the ink. The formula for the volume of a cylinder is $\pi r^{2} h$

We have the diameter, but we can easily find the radius by dividing it by 2. 0.400/2=0.200. Now, we plug our numbers into the formula.

$\pi 0.2^{2} *11.5 = 1.445 cm^{3}$

Now, we need to figure out how much ink he uses each week. We do this by dividing the volume by the amount of weeks, or 1.445/7 = 0.206.

So, the student uses $0.206 cm^{3}$ ink each week.

Alice and Bob have two positive integers, x and y respectively, glued to their foreheads, so that each can read the other’s numb

vazorg [7]

Step-by-step explanation: |x − y| = 1, ok lets play as Alice, my number is y, and the bob number is x.

the condition says that x-y = 1 or x-y = -1.

so, if you know x, then y = 1 +y or y = y - 1. so you have two possibilities.

let's see two cases : first, let's suppose there are no code in the conversation. Then the only way of being shure of your number, is if one of them have the lowest positive number, so the other should have the next one. So if Bob have the number one, Alice knows for shure that she has the 2. Bob knows that she has a 2, but that means he could have a 1 or a 3, but when he sees that Alice is shure about her number, he knows that his number is the 1.

the second case is where the conversation may be a sort of code, saying a phrase x times and changing when x = the number of the other person, in this case, bob will have the 201 and alice the 202.
