Answer:
Step-by-step explanation:
The equation can be written using information from the graph. The vertex of the parabola is (-3,-1). Use the vertex form 
by substituting h = -3 and k = -1. The equation becomes 
. It simplifies to 
. To find a, substitute the point (x,y) on the graph into the equation and solve for a. Substitute x = -2 and y = 0.
So the equation is 
. Convert to standard form by distributing the parenthesis and combining like terms.

Step-by-step explanation:
we know that
In the right triangle ABC
----> by SOH (opposite side angle B divided by the hypotenuse)
substitute the given values
Answer:
17.2 m
Step-by-step explanation:
The mnemonic SOH CAH TOA reminds you the relationship between the adjacent side of a right triangle and the opposite side is given by ...
Tan = Opposite/Adjacent
Filling in the given information, we have ...
tan(25°) = (8 m)/distance
distance = (8 m)/tan(25°) ≈ 17.156 m
The man is about 17.2 meters from the tower.
No it is not as if you simplify down 64:60, the closest you can get to 16:14 is 16:15
