Answer:
The new position of the bird is 1 ft below surface of pond.
Step-by-step explanation:
- Position of water bird after 15ft dive:
11-15= -4ft
- Position of water after rising 3 feet:
-4+3= -1ft
Therefor it id 1ft below the surface of the pond
Step-by-step explanation:
the slope of a line function is always the factor of x.
in our case : -1/4
it is the ratio y/x indicating how many units y changes, when x changes a certain amount of units.
in our case y decreases by 1 for every x increase by 4.
now, the perpendicular slope simply changes x and y upside-down and flips the sign.
in our case it is : 4/1 = 4
so, the line function in point slope form is then (using the new slope and the point coordinates)
y - 3 = 4(x - 1)
Use Pythagaras theorem :-
x^2 = 1.8^2 + 2.4^2 where a is distance required
x^2 = 9
x = 3 miles Answer
