Answer:What is your Question?
Step-by-step explanation:
Because when you build things with real wood and tools, negative length has no physical meaning. There are still two square roots, but we ignore the one that's not useful.
Answer:
a
Step-by-step explanation:
Using the tangent ratio, the height of the antenna, to the nearest meter, is AB = 8 m.
<h3>What is the
Tangent Ratio?</h3>
Tangent ratio is expressed as: tan ∅ = opposite/adjacent (TOA).
The information given has been sketched in the diagram attached below.
Find AC using the tangent ratio. Thus, we would have:
tan 29 = AC/CD
Substitute
tan 29 = AC/22
AC = tan 29 × 22 = 12.2 m.
Find BC using the tangent ratio:
tan 42 = BC/DC
Substitute
tan 42 = BC/22
BC = tan 42 × 22 = 19.8 m.
The height of the antenna, AB = BC - AC = 19.8 - 12.2 ≈ 8 m.

Answer: the maximum is (-2,5 )and the equation for the axis of symmetry is x = -2
Explanation if you want:
for the min and max: when a quadratic has a maximum point, that is the largest point that it will ever be at. When it has a minimum, that is the smallest.
- the +5 tells us that we have an upward movement of 5. The +2 means we actually move to the point -2. bc: (x+2)=0 = -2
- so, from our initial function, those are the changes.
for the axis of symmetry: basically, this is the line that splits the graph into two equal parts.
- it is the line that goes through the vertex (which we already know is (-2,5).
