Can someone help me with graphing this function?
Paul [167]

p.s. Excuse the scribble.

Step-by-step explanation:

This is a piece-wise function. The three intervals we need to worry about are [0, 1), [1,2], and [2,4].

Separate the functions into their pieces and draw out the individual graphs. Place them together onto the graph within their respective intervals.

In an obtuse isosceles triangle the angle measurements are, x∘, x∘, and (10x−2)=128∘. Find the measurement of one of the acute a
klemol [59]

Answer:

26°

Step-by-step explanation:

An obtuse triangle is a triangle that has one obtuse angle. Obtuse angle is an angle that is greater than 90 degrees but less than 180 degrees.

An isosceles triangle is a triangle that has two equal sides and angles.  

Therefore, an obtuse isosceles triangle is a triangle with an obtuse angle and two equal sides that have two equal acute angles (angle less than 90° ).

Given:

The three angles of the triangle are given to be x°, x°  and (10x−2) = 128°. The obtuse angle is 128°, the two x° are acute angles. We are not using equation 10x − 2 since the value of the obtuse angle has been given as 128°

The sum of angles in a triangle is 180°

∴  x° + x° + 128° = 180°

2x° = 180° - 128°

2x° = 52°

x° = 52° / 2

x° = 26°

The measurement of one of the acute angles is 26°

-x + y = -5 Y intersect and x intersect
Furkat [3]

Answer:

  • (0, - 5) and (5, 0)

Step-by-step explanation:

<u>Given line:</u>

  • - x + y = - 5

<u />

<u>The y-intercept is the point when x = 0:</u>

  • 0 + y = - 5
  • y = - 5

The point is (0, - 5)

<u />

<u>The x-intercept is the point when y = 0:</u>

  • - x + 0 = - 5
  • - x = - 5
  • x = 5

The point is (5, 0)
