Answer:
meters
Step-by-step explanation:
Let's take climbing down as "negative" and climbing up as "positive". Now, we can simply use the numbers and signs to find the change in elevation.
meters down means
meters up means
So, now we have:
<u>Eric's elevation changed meters above. So after the 2 moves, he is up by
meters.</u>
Answer:
Variance is the squared deviation and deviation is the difference of observed value from other values

Where,
Answer:
Area of the shaded region = 3.46 square units
Step-by-step explanation:
Measure of the interior angle of a regular polygon =
From the picture attached,
Number of sides of the given polygon 'n' = 6
Interior angle (∠BAF) of the given polygon =
= 120°
Measure of ∠BAC =
= 30°
Now we apply sine rule in ΔAGB,
sin(30°) =
=
BG = AB[sin(30°)]
=
= 1
By applying cosine rule in ΔABG,
cos(30°) =
=
AG = AB[cos(30°)]
=
=
AC = 2(AG)
= 2√3
Area of ΔABC =
=
=
=
Area of the shaded region = Area of ΔABC + Area of ΔFED
= 2(Area of ΔABC)
= 2√3
= 3.46 square units
