First. we use the Pythagorean theorem:
![a {}^{2} + b {}^{2} = c {}^{2}](https://tex.z-dn.net/?f=a%20%7B%7D%5E%7B2%7D%20%2B%20%20b%20%7B%7D%5E%7B2%7D%20%3D%20%20c%20%7B%7D%5E%7B2%7D%20)
Add the numbers in
![{30}^{2} + {b}^{2} = {50}^{2}](https://tex.z-dn.net/?f=%20%7B30%7D%5E%7B2%7D%20%20%2B%20%20%7Bb%7D%5E%7B2%7D%20%20%3D%20%20%7B50%7D%5E%7B2%7D%20)
start simplifying
![{b}^{2} = 1600](https://tex.z-dn.net/?f=%20%7Bb%7D%5E%7B2%7D%20%20%3D%201600)
![b = 40](https://tex.z-dn.net/?f=b%20%3D%2040)
So, the leg has a length of 40 mm.
Voltage= Current * Resistance
Plug in your values and solve for 'x' or resistance
Answer:
c.
Step-by-step explanation:
That is the only answer choice that makes the most sense.
±10 = √100; in this case, they want the non-negative value, so it is 10.
Answer:
Symbols of inclusion are symbols used in mathematical expressions that group terms or factors together. They indicate that when we are simplifying expressions, we are to perform what's inside the symbols first. The three types of symbols of inclusion are parentheses, brackets, and braces.
Answer:
1) f(3) means the temperature after 3 seconds
2) f(3) = 22 + 1.3(3) = 25.9
Temperature after 3 seconds is 25.9°C
3) f(t) = 35 means after t seconds, temperature was 35°C
4) 35 = 22 + 1.3t
1.3t = 13
t = 10 seconds
