Answer:
The region that contains the solution to the system is:
Region D
Step-by-step explanation:
- We are given first inequality as:
The graph of this will be a solid line passing through (9,0) and (0,3) with shading towards the origin.
Hence, it covers Region C and Region D.
- Similarly the second inequality is given by:
The graph of this will be a solid line passing through (-2/3,0) and (0,2) with away from the origin.
Hence, it covers Region A and Region D.
Hence, the intersection region that is covered by both the inequalities is:
Region D

Step-by-step explanation:
Answer: B = 43.9 , b = 18 71 , c = 8.45
Step-by-step explanation:
from the law of sine,
a b c
--------- = ---------- = ----------- a =25.3, C = 18.2 degree, A = 110.8 deg.
Sine A Sine B Sine C
to get the value of c,
a c
--------- = -----------
Sine A Sine C,
25.3 c
----------- = -------------
Sine 110.8 Sine 18.2
Now cross multiply to get the value of c
c x Sine 110.8 = 25.3 x Sine 18.2
Therefore c = 25.3 x Sine 18.2
------------------------
Sine 110.8
checking for Sine 18.2 in your log tables/calculators , ie, sine 18 under 2, = 0.3123 and sine 110.8 = 0.9348
c = 25.3 x 0.3123
--------------------
0.9348
= 8.45.
To get angle B, sum total of a triangle is supplementary ie, 180 degree.
meaning that A + B + C = 180
Therefore, angle B = 180 - ( 110.8 + 25.3)
= 180 - 136.1
= 43.9
Now to find b,
b c
------------- = ------------
Sine B Sine C
b 8.45
--------- = ------------
Sine 43.9 Sine 18.2
b x sine 18.2 = 8.45 x Sine 43.9
b = 8.45 x 0.6934
--------------------
0. 3123
b = 18.708
= 18.71.
The final Answer = B = 43.9, b = 18.71, c = 8.45

Answer:
The possible value of 'x' is: 3.
Step-by-step explanation:
A polynomial has no real solutions when the discriminat is less than zero. Given the following polynomial: the discriminant is given by:
In this case, a=1, b=2. By substituting those values:
⇒
Given that the discriminant should be less tha zero, then 'c' must be greater than one.
In this case, the only possible value of 'x' is: 3.
Answer:
3
Step-by-step explanation:
Given
x² + 2x + c = 0 ← in standard form
with a = 1, b = 2 and c = c
If there are no real solutions then the discriminant
b² - 4ac < 0, that is
2² - (4 × 1 × c ) < 0
4 - 4c < 0 ( subtract 4 from both sides )
- 4c < - 4
Divide both sides by - 4, reversing the sign as a consequence
c > 1
Hence a possible value of c is 3
