√(3x+4)≥0 (otherwise it becomes imaginary)
3x+4≥0
3x≥-4
x≥-4/3
Y=2(0)-5 (it's the lowest x value, and that means it will limit y)
Y=-5
As x can be > -4/3, let's try for another Y value
Y=2√(3(5/3)+4)-5
Y=2√9-5
Y=6-5
Y=1
1>-5
So, Y≥-5
Answer is A
2*12-1=23 ? or 12=2n-1, n = 6.5, not sure what you mean
Answer:

Step-by-step explanation:
<u><em>The complete question in English is
</em></u>
Find the height of the tower with the data provided by the engineering team. Value of the segment ab= 50 m. The length between the child and the tip of the tower is 250 m
<u><em>The picture in the attached figure

we know that
In the right triangle ABC
Applying the Pythagorean Theorem
we have
substitute
Answer:
CE = AD/2
Step-by-step explanation:
C is the center of small circle
- Point E is on same circle, therefore CE = radius of small circle
- AD passes through the center of small circle and both points are on same circle, therefore AD is diameter of small circle
<u>Since diameter is double of radius:</u>
