Answer:
See attachment
Step-by-step explanation:
The given function is 
This function is in the form:
Where the axis of symmetry is given by 
By comparison, we have -h=2.
This implies h=-2
Therefore the axis of symmetry is 
The maximum value occurs at the vertex, given by (h,k)=(-2,8)
See attachment for the axis of symmetry and maximum point.
To find the slope of the perpendicular line, you can take the negative reciprocal of the slope of the line it is perpendicular to.
Taking the negative reciprocal of -1/5 gives 5.
Now we have y=5x+b, where b is the y-intercept. Since we know that the perpendicular line passes through the point (1,4), we can substitute those values into the equation we have to find b.
y=5x+b
4=5(1)+b
4=5+b
b=-1
Therefore, the equation of the perpendicular line is y=5x-1.

She eats 45 grams of proteins per day. There is 17 days.
Multiply the two numbers together.
45 x 17 = 765.
the Athlete eats 765 grams of protein during those 17 days of training.
hope this helps
