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
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 :/
Answer:
2× 6^n-1
Step-by-step explanation:
using formula
tn= a.r^n-1
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.
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 :)
