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.
75cm²
Explanation:
10 times 15 is 150 and since it is a triangle you divide in half so the answer is 75. And in this case the 18 is not needed.
1. x=6
2. x=4
3. x=3.5
please mark me brainliest i really need it to move up!! yeah
Answer:
y = -2
Step-by-step explanation:
This one is easy. As you may know, a axis of symmetry is the line where everything is the same on both sides of it. For this, you can use trial and error or just look at the points on either side. For y = -1, that will put the line in an awkward spot, crossing through 2 slanted lines instead of corners. For x = -1, this just cuts through the shape straight up and down and does not make the shape look equal on both sides of the line at all. Same goes for x = -2. I should probably mention, when you see a line that is described as "x = 1", it is a vertical line, because the line is constantly staying on the point x = 1, while having an infinite number of y-values. When you see "y = 1", it will be horizontal for the same reason, just flipped.
