Given that PS is the perpendicular bisector of QR, PQ=3.5m+18, and PR=6m+3, identify PQ.

kolbaska11 [484]

Answer:

$PQ=39\ units$

Step-by-step explanation:

we know that

$QS=RS$ ----> equation A

Applying Pythagoras Theorem

$PQ^2=SP^2+QS^2$ -----> equation B

$PR^2=SP^2+RS^2$ -----> equation C

substitute equation A in equation C

$PR^2=SP^2+QS^2$

we have that

$PR^2=PQ^2$

$PR=PQ$

substitute the given values

$6m+3=3.5m+18$

Solve for m

$6m-3.5m=18-3$

$2.5m=15$

$m=6$

Find the value of PQ

$PQ=3.5m+18$

substitute the value of m

$PQ=3.5(6)+18$

$PQ=39\ units$

The graph of a function f(x) is shown below:<br><br><br><br> What is the domain of f(x)?

Pie

The domain is the scope of the x values. In this case (-2,-1) is a hole, so x>-2 is one end of the domain, while (3,3) is defined. So the domain using interval notation is (-2,3] which can also be expressed -2 < x ≤ 3, answer option 1
