First, simplify the expression of the function 
highlighting the perfect square:
Then find the vertwx of parabola. When x=2, f(2)=2 and the coordinates of the vertex are (2,2). The axis of symmetry passes through the vertex and is parallel to the y-axis. Therefore, its equation is x=2 (see attached graph for details).
Answer: x=2.
Answer: i dont know, gook luck
Step-by-step explanation:
Answer:
W = 
Step-by-step explanation:
given the formula V = LWH
to solve for W divide both sides by LH, hence
W =
W times 73 because product means multiply
The distance that Kirsten and Molly need to bike on their third day is obtained by subtracting the sum of the distances they have traveled after two days from the length of the entire route.
distance left = 156 miles - (64 miles + 45 miles)
= 47 miles
Thus, Kirsten and Molly need to bike 47 miles on their third day.
