Rewrite s = 4 + sqrt(s+2) as s-4 = sqrt(s+2)
Square both sides: s^2 - 8s + 16 = s + 2
combine like terms: s^2 - 9s + 14 = 0
Factor this: (s-7)(s-2)=0
Solve for s: s={7, 2}
Answer:
Troposphere
Step-by-step explanation
contains the air we breath and is often reffered to as the lower atmosphere
Answer:
b. 23
Step-by-step explanation:
Using factor trees
23 115
∧ ∧
1 23 5 23
So,
23= 23
115= 23
If you circle the common factors in each factor tree, you get 23.
Therefore your answer is B
y = Acos(Bx) + D;
D = 4, A = 2. Now T = 2π/B = 5π/8, B = 2π/(5π/8) = 16/5
WE get y = 2cos(16/5x) + 4
You have not provided the options, therefore, I can not provide an exact answer.
However, I will help you with the concept
In a triangle, the circumcenter is defined as the point of intersection of the three perpendicular bisectors in the triangle
The circumcenter is characterized by the following:
1- The circumcenter is the center point of the circumcircle
2- The circumcenter is equidistant from the three vertices of the triangle
<u>3- Position of circumcenter:</u>
in acute triangle ........> it lies inside the triangle
in right-angles triangle .......> it lies at the midpoint of the hypotenuse
in obtuse triangle ..........> it lies outside the triangle
Hope this helps :)
