What is the distance between (1,-5) and (-3,6)

spin [16.1K]

Answer:

$\large\boxed{\sqrt{137}}$

Step-by-step explanation:

The formula of a distance between two points:

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

We have the points (1, -5) and (-3, 6). Substitute:

$d=\sqrt{(6-(-5))^2+(-3-1)^2}=\sqrt{11^2+(-4)^2}=\sqrt{121+16}=\sqrt{137}$

A garden has the form of a right triangle. One leg of the triangle is formed by a 2400-ft long sea wall. The hypotenuse of the

stepladder [879]

Answer:

given leg: 2400 ft
other leg: 1000 ft
hypotenuse: 2600 ft

Step-by-step explanation:

The Pythagorean theorem tells a relation between the leg lengths and the hypotenuse. If x represents the unknown leg length, then we have ...

x^2 + 2400^2 = (x +1600)^2

x^2 +5760000 = x^2 +3200x +2560000 . . . . eliminate parentheses

3200000 = 3200x . . . . . . . . . subtract x^2+2560000

1000 = x . . . . . . . . . . . . . . divide by 3200

The other leg length of the garden is 1000 ft. The garden is a triangle with side lengths 1000 ft, 2400 ft, 2600 ft.
