I don't have to go to the ice. I'm in trouble. Dave Canterbury crawled on his belly to look over that cliff. What I have to hope now is I can actually get them to take a bet here that'll give me usage of the rope.

Yeah, here we go, here we go. If I can tell you how high that is without even looking over it, do I get to use your rope?

Without looking? Yes, and you're not going to use a rope to do it, Dave. That would be cheating.

Within how many feet? Within 10 feet? Less than 10 feet?

All right, Colonel, I'll take that action. You're on, Daddo.

Right, give me some space. What do you need?

Oh, a rock. A rock I'll start with.

Yeah, a rock. Okay, give me a second.

Give me a second. Below 2 and 1/2 seconds. 2 and 1/2, 2 and A4, 2 squ 4 and a bit onto that 'cause it's going to be four 72 feet.

I got to say, I think that's pretty close just for my ballparking it. Just tell me when you confirm my mathematics by counting each stretch of rope as he pulls it up.

Dave can ballpark the height of the cliff. What do you make it? About 65 feet.

So 72 is definitely within 10 feet. Come on, team. Time to learn.

Distance traveled is the initial velocity times the time it travels plus half of the acceleration times the time it traveled squared.

So it's a half of 32. 32 feet per second per second is the acceleration due to gravity, which is 16 times... um 5, which is the time squared, which comes up to 72.

It sums. Do you not do mathematics? That's what engineers do. We do them in our head. English measure.

So let’s dig a little bit more into matrices and their inverses, and in particular, I’m going to explore the situations in which there might not be an inverse for a matrix. So just as a review, we think about if we have some matrix A, is there some other…

Example using estimation for decimal products

We are told that 52 times 762 is equal to 39,624, and then we’re told to match each expression to its product. These products, this is the exercise on Khan Academy. You can move them around so the product can be matched to the appropriate expression. So p…
