Answer:
f(½) = 1.73
f(¼) = 1.32
Step-by-step explanation:
You will find the complete question attached as a picture alongside the solution.
y = f(x) =
When f(x) ⇒ f(½); that is, x = ½
y = =
y = 1.7320508076 ≈ 1.73
y = <u>1.73</u> (to the nearest hundredth)
When f(x) ⇒ f(¼); that is, x = ¼
y = =
y = 1.316074013 ≈ 1.32
y = <u>1.32</u> (to the nearest hundredth)
Answer:
============================================================
Explanation:
Apply the distance formula to find the length of segment WX
W = (x1,y1) = (-10,4)
X = (x2,y2) = (-3, -1)
Segment WX is exactly units long which approximates to roughly 8.6023253
-------------------
Now let's find the length of segment XY
X = (x1,y1) = (-3, -1)
Y = (x2,y2) = (-5, 11)
Segment XY is exactly units long which approximates to 12.1655251
-------------------
Lastly, let's find the length of segment WY
W = (x1,y1) = (-10,4)
Y = (x2,y2) = (-5, 11)
We see that segment WY is the same length as WX.
Because we have exactly two sides of the same length, this means triangle WXY is isosceles.
