PARALLEL PERPENDICULAR OR NEITHER

Answers

Answer:

Parallel

Step-by-step explanation:

Using these points, we can determine that the equation is as follows:

Line B: y = -2/3x + 7/3

And since Line A has the same slope, it would make Line A's equations like this:

Line A: y = -2/3x - 11/3

This makes these equations Parallel to each other because they have the same slope with different y-intercepts.

FunctionNot a functionFunctionNot a function

========================================

Explanation:

If x repeats itself, then we don't have a function. For instance, relation 2 has the x value -4 show up twice. That input leads to multiple outputs which is why we don't have a function. Relation 4 is a similar story (this time the input 'u' shows up twice).

Relations 1 and 3 don't have this issue, so they are functions.

Question 4 Objective: Apply properties of squares to solve mathematical and real-world problems. The perimeter of a square is 116 cm. What is the approximate length of its diagonal?

help​

Answers

Answer:

41.01 cm

Step-by-step explanation:

Answer:

  41.0 cm

Step-by-step explanation:

The side length is 1/4 the length of the perimeter.

  s = P/4

The diagonal length is √2 times the side length.

  d = s·√2

Then the diagonal is ...

  d = (P/4)√2 = (116 cm)(√2)/4 ≈ 41.01 cm

The diagonal is about 41.0 cm long.
