Roots can be written as fraction exponents. An exponent of 1/2 means the square root.
So, for the second problem, they've reversed the situation: Now we have the temperature, and we have to think backwards to figure out the number of cricket chirps (in five minutes)!
We ended up with 60 degrees (somehow). Well, let's subtract 37. That gives us 23. What does this number mean? It is the number of times the cricket chirps in 15 seconds. But we want five minutes... I bet you can take it from here... :)
Answer:
or 15.231546
Step-by-step explanation:
The answer to that is 800 hundred. Here is a saying 5 or more raise the score 4 or less give it a rest
Slope of AB = (5 - 2)/(7 - 4) = 3/3 = 1
slope of BC = (2 - 2)/(4 - 9) = 0
m<span>∠ABC = arctan 1 = 45°
