Answer:
C.
Step-by-step explanation:
that the coordinates of the vertices of the triangle after a reflection across the parallel lines .
Given the function f(x)=x^2+5x+5 , to get the zeros we solve using quadratic formula;
x=[-b(+or-) sqrt(b^2-4ac)]/(2a)
from our function;
a=1,b=5, c=5
thus,
x=[-5(+or-)sqrt(5^2-4*1*5)]/(2*1)
x=[-5(+or-)sqrt(25-20)]/2
x=[-5+/-sqrt(5)/2
The answer is option C
A. 40 km/h
this because (2,80)/2 is (1,40) or 40/1, so it would be 40 km/h
Answer:
We can make it in 36! ways.
Step-by-step explanation:
We have 36 photos and we need to arrange on a gallery wall.
So, since we need to arrange them so we will use permutation
And the number of ways arranging these 36 photos will be 36!

So, here we have n=36
