Interval notation uses parenthesis and brackets, while inequality notation uses inequality symbols.
a)
Interval notation: [-4, 8)
Inequality notation:
x >= -4, x < 8
---For inequality notation, it can also be written as two separate inequalities. I am not sure what your teacher is looking for, so I will provide both the compound and separate formats.
b)
Interval notation: (-infinity, 7)
Inequality notation: x < 7
c)
Interval notation: (-infinity, -6) U (0, infinity)
Inequality notation:
x < -6, x >= 0
Hope this helps!
Given
in ∆ABC
AB = 5cm
BC = 6 cm
AC = 7 cm
now,
as we have to make ∆PQR inside it
than, possibly ∆PQR's sides length is,
PQ = ½ of CB (according to mid point theorem)
→ CB = 6cm → 6/2 → 3cm
PQ = 3cm
QR = ½ of AC
→ AC/2 = 7/2 = 3.5 cm
RP = ½ of AB
→ AB/2 = 5/2 = 2.5cm
therefore, length of
PQ = 3cm
QR = 3.5 cm
PR = 2.5 cm
Hope this answer helps you dear!
