Answer:
Died speciman prior would be best to measure the bird’s mass.The length (also bill-to-tail length) of a bird is usually measured from dead specimens prior to their being skinned for preservation. The measurement is made by laying the bird on its back and flattening out the head and neck gently and measuring between the tip of the bill and the tip of the tail.
Answer:
if you simplify and solve you will get y=3
Answer:
x=2
Step-by-step explanation:
The axis of symmetry can be calculated using the following formula:

In order to use this formula, we need to have the function written in it's polynomial formula:

In order to do so, we have to isolate Y from the excercise's formula.

Then we resolve the square of the binomial knowing that (a+b)^2=a^2+2.a.b+b^2


Now we have that:



As we have now the polynomyal formula, we know that a=-2, b=8 and c=-13. We supplant on the formula and get:
