Answer:
Apply cosine rule:
c²=b²+a²-2ba cosC
C= pi/3 = 180/3 = 60 degrees
cosine 60 deg = 0.5
c²=2²+3²-[2×2×3×0.5]
c²=7
c=√7
c=2.645 ;length of third side of angle

Answer:
h greater-than-or-equal-to negative 432
Step-by-step explanation:
* multiply each side by -24 *

IMPORTANT NOTE: when multiplying an inequality by a negative number you must flip the sign. So if the inequality sign was once facing the constant ( 18 ) then it will flip and face the variable ( h )
Thus,
h ≥-432
Which can also be expressed as h is greater than or equal to negative 432
Extra notes: You only have to flip the inequality sign if it's being multiplied by a negative number. Meaning if its multiplied by a positive number then the inequality sign does not flip.
Answer:
33=2x+y, 48=3x+y
Step-by-step explanation:
Sorry my internet isn't working well. Go to math-way and put that in and it will give you the answer :)
We can re-write the equation √(1-x) - 2y = 2 → - 2y = 2 - √(1-x)
→ 2y = - 2 + √(1-x) → and y = [ - 2 + √(1+x)]/2
Tis function "exists" as long as the radical is > or = to zero:
1+x > or = 0 → x>-1
{x ∈ R for x> =0}
