C
Step-by-step explanation:
Answer:
The bird will be at a ground distance of 10.04 units away.
Step-by-step explanation:
Vertex of a quadratic function:
Suppose we have a quadratic function in the following format:

It's vertex is the point 
In which


Where

If a<0, the vertex is a maximum point, that is, the maximum value happens at
, and it's value is
.
Equation for the height:
The height of the bird after x seconds is given by:

Which is a quadratic equation with
.
When the bird is at its highest?
Quadratic equation with
, and thus, at the vertex. The ground distance is the x-value of the vertex. Thus

The bird will be at a ground distance of 10.04 units away.
I don’t know exactly but I tried the math and it’s either 4 or 5%
I got 155♀️ I don’t know cause I did PEMDAS and got 155
Answer:
151200 ways
Step-by-step explanation:
Well assuming the numbers go from 0 to 9
we have
_ _ _ _ _ _ six spaces
in the first one can go one of the ten so the first one has 10 options
10*_ _ _ _ _
the second one has 9 options because we have used one alredy
and so on
10*9*8*7*6*5=151200
