Answer:

  {Segments, Geometric mean}

  {PS and QS, RS}

  {PS and PQ, PR}

  {PQ and QS, QR}

Step-by-step explanation:

The three geometric mean relationships are derived from the similarity of the triangles the similarity proportions can be written 3 ways, each giving rise to one of the geometric mean relations.

  short leg : long leg = SP/RS = RS/SQ   ⇒   RS² = SP·SQ

  short leg : hypotenuse = RP/PQ = PS/RP   ⇒   RP² = PS·PQ

  long leg : hypotenuse = RQ/QP = QS/RQ   ⇒   RQ² = QS·QP

I find it easier to remember when I think of it as <em>the segment from R is equal to the geometric mean of the two segments the other end is connected to</em>.

__

  segments PS and QS, gm RS

  segments PS and PQ, gm PR

  segments PQ and QS, gm QR

What is the completely factored form of f(x) = – 2 – 5 + 6? f(x) = (+ 2)( – 3)( + 6) f(x) = (+ 2)( – 3)( – 6) f(x) = (– 2)( + 3)
PolarNik [594]
All I keep getting for my answers is y= -1
I don’t know how to put in that form, it’s been a while for me, but it’s either the 3rd or 4th answer. Sorry :/

The graph of f(x) = 2x is shown on the grid. The graph of g(x) = ()x is the graph of f(x) = 2x reflected over the y-axis. Which
lakkis [162]

Answer:

While the graph is not shown, it would be the graph of g(x) = -2x.

Step-by-step explanation:

A reflection across the y-axis negates the x-coordinate of every point.  To find the function associated with this, we would replace x with -x:

g(x) = f(-x) = 2(-x) = -2x

The function would be g(x) = -2x.

What is the area of the composite figure below?
musickatia [10]

Answer:

33 sq cm.

Step-by-step explanation:

Let's calculate each shape serperately,

--------

For the square, the area is 25 since

5 × 5 = 25

-------

For the rectangle, the area is 8:

4 × 2 = 8

-----

Add these together to get 33 sq cm

Have a good day :)
