Avisitor is staying in a tent that is 7 miles west of the closest point on a shoreline to an island. the island is 2 miles due north of the shoreline. the visitor plans to travel from the tent to the island by running and swimming. if the visitor runs at a rate of 8 mph and swims at a rate of 2 mph, how far should the visitor run to minimize the time it takes to reach the island? round to two decimal places.

first one is a: renaming a fraction. second one is c: de-c

my explanation is that these were the answers on edg : )

if you need , reply with more info. u.

t hope this

:

let f (x ) is a function and c be a positive real number,   the graph of the function g (x ) = f (cx ) is represented as follows.

when, c > 1,   the function compresses it in the x - direction.

when, 0 < c < 1, the function stretches it.

the function is g ( x ) = (9x )2.

the heighest power of x in g ( x ) = (9x )2 is 2, so the parent function is square function.

the equation of parent function is f ( x ) = x 2 .

the function is g ( x ) = (9x )2 and the parent function is f ( x ) = x 2 .

so, the functions f and g have the following relationship.

g ( x ) = f ( 9x ).

compare the function g ( x ) = f ( 9x ) with g (x ) = f (cx ).

c = 9 ( > 1 ).

so, the function g (x ) = (9x )2 compresses it in the x - direction.
