Dimension of an equilateral
Axis of symmetry is the line x = h, where (h, k) is the vertex. Plug -5 into the equation to get k.
f(-5)=-(-5)^2-10(-5)+16=-25+50+16=41
(-5, 41)
A and C i believe that’s correct
<u>Answer:</u>
csc = 5/4
<u>Step-by-step explanation:</u>
Assuming that the two given points 3/5 and 4/5 are the two sides of a triangle and a right angle 0 with legs x and y and z as its hypotenuse.
Then using Pythagoras Theorem:





Taking square root on both the sides:

Now, 
and we know that 
Therefore, csc = 5/4.
