What is the distance between the points (1, -4) and (1, 0)
tino4ka555 [31]

For this case we have that the distance between two points is given by:


d = \sqrt{(y2-y1)^2+(x2-x1)^2}

Given the points:


(x1, y1) = (1, -4)(x2, y2) = (1,0)

We substitute in the formula:


d = \sqrt{(0 - (- 4)) ^ 2 + (1-1) ^ 2}

d = \sqrt{(4 ^ 2 + 0 ^ 2)}

d=\sqrt{16}

d = 4

So, the distance is d = 4

Answer:


d = 4

Helppppppp mathhhhhhhh

Again using the Pythagorean Theorem:

h^2=x^2+y^2, where h is the hypotenuse of a right triangle and x and y are the side lengths.  You are given that the hypotenuse is 34 ft and the base side is 16ft. Let h=34, x=16, and y=height, then you have:

34^2=16^2+y^2

y^2=34^2-16^2

y^2=1156-256

y^2=900

y=√900

y=30 ft

So the ladder will reach a spot 30 feet high on the building.

Answer:

18ft^2

Step-by-step explanation:

I'm going to use a dilation method to help solve this.

First we need to find your base. So 12/4 = 3.

6*3 = 18.

18 ft^2
