Answer:

1. 38, 80, 89 and 4. 14, 15, 29

I don't know if there is supposed to be only one, but both of those do not form right triangles.

Step-by-step explanation:

Evaluate all of them and see if they meet the requirements of the Pythagorean Theorem, a² + b² = c².

1. 38, 80, 89

a² + b² = c²

38² + 80² = 89²

1444 + 6400 = 7921

7844 ≠ 7921.

This is an answer because it doesn't satisfy the Pythagorean Theorem.

2. 16, 63, 65

a² + b² = c²

16² + 63² = 65²

256 + 3969 = 4225

4225 = 4225

This isn't the answer because it satisfies the Pythagorean Theorem.

3. 36, 77, 85

a² + b² = c²

36² + 77² = 85²

1296 + 5929 = 7225

7225 = 7225

This isn't the answer because it satisfies the Pythagorean Theorem.

4. 14, 15, 29

a² + b² = c²

14² + 15² = 29²

196 + 225 = 841

421 ≠ 841

This is an answer because it does not satisfy the Pythagorean Theorem.

Answer:

  1. 15 - 7 (Parentheses)
  2. 3² (Exponents)
  3. 8 × 2 (Multiplication)
  4. 40 ÷ 8 (Division)
  5. 5 + 9 (Addition starting from the leftmost)
  6. 14 + 16 (Addition after the first addition operation)

Concept:

When encountering questions that ask for simplifying expressions through operation, following the PEMDAS method would be easier:

  • <u>P</u>arentheses
  • <u>E</u>xponents
  • <u>M</u>ultiplication
  • <u>D</u>ivision
  • <u>A</u>ddition
  • <u>S</u>ubtraction

Therefore, the whole process of simplifying the given expression should follow the PEMDAS method. <u>For extra</u>, whenever there are two occurences of the same operation, then prioritize the leftmost and go right.

Hope this helps!! :)

Use technology to approximate the solution(s) to the system of equations to the nearest tenth of a unit.
Ivanshal [37]

Answer: (2.6, 0.4), (3.6,0.6) is the solution of given equations.

Explanation: Given Functions are:

f(x)=log(x) and g(x)=|x-3|

Since, the solution of the above equations will be get after solving these two equations. Or we can say that, the intersection point of the curves made by the above equation is the solution of  the system.

After making the graph of functions f(x) and g(x)  we observed that, f(x) and g(x) are intersecting at points (2.587, 0.413) ≈(2.6,0.4) and (3.55,0.55)≈(3.6,0.6).

Thus, solution of f(x) and g(x) are (2.6,0.4) and (3.6,0.6).

Therefore, options first and fourth is correct.
