Answer:
A) SQ is the geometric mean between the hypotenuse and the closest adjacent segment of the hypotenuse.
Step-by-step explanation:
In this geometry, all of the right triangles are similar. That means corresponding sides have the same ratio (are proportional).
Here, SQ is the hypotenuse of ΔSQT and the short side of ΔRQS.
Those two triangles are similar, so we can write ...
(short side)/(hypotenuse) = QT/SQ = QS/RQ
In the above proportion, we have used the vertices in the same order they appear in the similarity statement (ΔSQT ~ ΔRQS). Of course, the names can have the vertices reversed:
QT/SQ = SQ/QR . . . . . QS = SQ, RQ = QR
__
When this is rewritten to solve for SQ, we get ...
SQ² = QR·QT
SQ = √(QR·QT) . . . . SQ (short side) is the geometric mean of the hypotenuse and the short segment.
You plug in -3 for x for 4(-3)+5 =-7
Answer:
The equation is 12x=180. You worked for 15 hours.
Step-by-step explanation:
Do 12x=180 then divide by 12. You get x=180/12. Then simplify
Answer:
The table is:
x y
1 1
2 5
3 9
The graph B shows the relationship y=4x-3
Step-by-step explanation:
We need to fill the table using the rule:
To find y multiply x by 4 and then subtract 3.
Writing rule in mathematical form:
y=4x-3
Now for completing the table we need to put x=1,2 and 3 and find values of y
So, the table is:
x y
1 1
2 5
3 9
The graph B shows the relationship y=4x-3
11/25
