How can you use powers and exponents to express known quantities

The most common ways is to indicate orders of magnitude through multiplying by powers of 10. I expect you’re at least seen something like 6.022∗1023

show up in your texts. The important part for this discussion is 1023

, because it gives us an idea of just how large this value is. If we wrote it all out, it would be: 602,200,000,000,000,000,000,000. You can do the same thing in the other direction, too. 10−28
Common value for certain types of physics, but a very, very small one.

Alternately, when dealing with probability, the function for determining the probability of series of independent events with the same odds is

where p is the probability of a certain outcome and n is the number of times the event occurs. For example, if we want to know what the odds of getting five heads in a row while flipping a coin we’re looking at 125
or 132

But the thing with powers of 10 is the most common I’ve seen, it even occasionally gets named Scientific Notation.

PolarNik [594]

Answer:

$70 is what he would have left. Since each trip is $14 you would multiply that by the amount of times he went which was 11. 14x11 is $154. But you need what he has left so you take his total amount $224-$154 and get $70.

Part b.) 16 times. He has $224 total. You want to find out how many times he can go on the tool roads. We know the toll roads cost $14 each time. So you do $224/14 and get an even amount of 16. He would be able to use it 16 times before he have no money left.

D = 2r => 12.6 = 2*r => r=6.3
A = π*r^2 = (3.14) * (6.3)^2 = (3.14)*(39.69) = 124.6266 which is approximately 124.63

Hope this helps!
