Answer:
THE AXIS OF SYMMETRY IS ALWAYS THE X VALUE OF THE VERTEX
Step-by-step explanation:
The vertex is where the graph performs the u shape bend.
The vertex is always -b/2a. so in problem one, it would be 6/2(3) which is 1. That is the x value so the axis of symmetry would be x=1.
8.3 is 10 times 0.83 so it is greater by a factor of 10
Answer:
p=59.19°
Step-by-step explanation:
We first find the length BD
BD=√(6²+5²)=√61
Using Pythagorean theorem,we find p by:
cos(p°)=4/√61
p=cos^-1(4/√61)
p=59.19°
LW = A
L(L - 3) = 18
L^2 - 3L - 18 = 0
(L - 6) (L + 3) = 0
L could be 6 or -3 ( -3 cannot be a length of a side of a rectangle since it’s negative.)
So L = 6 and W= 3
