3. If 0 < a < 1, so the solution set of inequality a is...
If 0 < a < 1, the solution set of inequality a is all real numbers that are greater than 0 and less than 1.
In other words, the solution set of the inequality a is the interval (0,1), which includes all real numbers x such that 0 < x < 1.
For example, if a = 0.5, then the solution set of the inequality a is the interval (0,1), which includes all real numbers x such that 0 < x < 1. This interval includes all numbers between 0 and 1, including 0.5.
If a is any other number between 0 and 1, the solution set of the inequality a will also be the interval (0,1).
I hope this helps!

di garis bilangan, terlihat bahwa panah -1 bulatanmya dihitamkan •, berarti -1 ikut. jadinya ≤terlihat bahwa panah 2 bulatannya kosong °, berarti 2 tidak ikut, jadinya >13. Y =ax2 + bx +c Y = k For which value of k ( in term a,b and c ) will thesystem have exactly one solution? What is that solution?what is the relationship betweenthis solution you’vefound and the graph of Y = ax2 + bx + c?
its so easy...just make a substitution and use the diskriminant properties. the K is should the vertex ordinat for y=ax2+bx+c
14. make the graph of this equation : 2x + y = 2!

16. It is currently 0°C outside. The temperature is dropping 2.5°C every hour. Write and solve an inequality that represents the number of hours that must pass for the temperature to drop below −20°C.
Jawaban:
setiap satu jam temperatur turun 2,5°c. agar bisa mencapai -20°c dibutuhkan waktu berapa jam.
-20°,÷2,5=8
So it takes 8 hours to bring the temperature down to minus 20 degrees Celsius.

17. What is the solution of this problem?Please help me to solve this pattern answer? = ....
Terlihat polanya perkolom adalah:
- (hati x bulat) + trapesium
-(4 x 6 ) + 11 = -24 + 11 = -13
-(6 x 8) + 7 = -48 + 7 = -41
-(8 x 9) + 5 = -72 + 5 = -67
-(10 x 10) + 3 = -100 + 3 = -97
maka
-(2 x 4 ) + 13 = -8 + 13 = 5

20. What is the molarity of H2SO4 solution which contains 49.04 g in 1 litre solution.
Materi : Asam - Basa
Answer:
0.500408163236 (0.5 molarity)
Explanation:
to calculate the molarity of sulfuric acid H2SO4.
KNOWN;
m H2SO4 = 49.04 g
v = 1 litre
Mr H2SO4 =
Mr H2SO4
= (2 × Ar h) + (1 × Ar S) + (4 x Ar o)
= (2×1) + (1×32) + (4×16)
= 2+32+6
Mr H2SO4 = 98
(1.The formula for calculating the moles of sulfuric acid
n = m/Mr H2SO4
n = 49.04/98
= 0.50040816326 or 0.5
(2.The formula for calculating the molarity of sulfuric acid
M = n/v
M = 0.50040816336/1
= 0.5
→so the molarity of sulfuric acid H2SO4 is 0.5
hope it helps, thank you
