A small craft in lake Ontario sends out a distances signal. The coordinates of the boat in trouble are (57,64). One rescue boat

KatRina [158]

Answer:

The coast guard craft will get to the distressed boat the fastest.

Step-by-step explanation:

The coordinates of boat are (57,64).

The coordinates of rescue boat are (67,83).

The coordinates of coast guard craft are (65,46).

Both rescue crafts travel at the same rate. One of them will get to the distressed boat the faster, whose distance from the boat is least.

Distance formula:

$d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

The distance between boat and rescue boat is

$d_1=\sqrt{(67-57)^2+(83-64)^2}=21.4709105536\approx 21.47$

The distance between boat and coast guard craft is

$d_2=\sqrt{(65-57)^2+(46-64)^2}=19.6977156036\approx 19.70$

Since the distance between boat and coast guard craft is least, therefore coast guard craft will get to the distressed boat the fastest.

Farmer has 2,400 feet of fencing and wants to fence off a rectangular field that borders a straight river. he needs no fence alo

konstantin123 [22]

Let each side perpendicular to the river be "x".
Then the side parallel to the river is "2400-2x".

The function would be:

A(x) = x(2400-2x)

And it would be: A(x) = 2400x - 2x^2

To solve the equation:

You have a quadratic with a = -2 and b = 2400

Maximum Area happens where:

x = -b/2a

= -2400/(2*-2)

= 600 ft. (width)

To find the length it will be:

= 2400-2x = 2400-2*600 = 1200 (length)
