Hi!
We can use the Pythagorean Theorem to see if it is a right triangle.
The Pythagorean Theorem is a² + b² = c².
c = the longest side, or the hypotenuse. In this case, the hypotenuse should be 65.
39 can be a, and 52 could be b, or 52 could be a, and 39 could be b. It doesn't matter.
39² + 52² = 65²
Is this equation true?
Yes! This equation is true.
The answer is Yes, this is a right triangle.
Hope this helps! :)
I attached the work/steps for my answer.
Answer:
8 and 4
Step-by-step explanation:
i had it
Equation 1- does a u up so that is not stight
equation 2- does a straight line down in the y-axis but has a small curve
equation 3- does a stight line
equation 4- you sure that right
but if i had to choose i would go with equation 3, hope it helped
Answer:
Depending on how the input of each function defined,
- The first choice
, - The third choice
- The fourth choice
might be functions.
Step-by-step explanation:
A function between two sets (domain and range) should
- be defined for all elements in the domain, and
- map each element from the domain to exactly one element in the range.
The second choice can't be a function since the element 
from the domain is mapped to more than one element in the range.
Keep in mind that a function should be defined for all elements in its domain. For the first relation to be a function, its domain needs to be 
. Similarly, the domain for the third and fourth relations should be 
and
