Triangle HIJ has coordinates H(-3,5), (8,2), and J(-3,-5). Find

Vlad1618 [11]

Answer:

H (x= -3 , y=5)

I (x=8 , y=2)

J (x= -3 , y= -5)

D is the distance between the 2 points so just plug in the x and y cords of each of the corresponding points

so for (HI)

you plug in 2 on the red x

and 8 on the red y

then -3 in the blue x

and 5 in the blue y

All together he made 23.40
One third of $17.55 is $5.85
When you add $17.55 and $5.85 together you get $23.40

You are given the following points: A=(−6,−5,18)A=(−6,−5,18), B=(−17,0,−1)B=(−17,0,−1), C=(7,−11,−20)C=(7,−11,−20). Which point

Answer:

See answer below

Step-by-step explanation:

Since the yz-plane represents all the points (0,y,z) , then the distance of any point (x,y,z) to the yz-plane is given by the difference vector

d= (x,y,z) - (0,y,z) = (x,0,0)

then the distance |d| is

|d|=√ ( x² + 0²+0²) = |x|

then the distance only depends on |x|. Therefore A has the minimum distance to the plane and its distance dA is

dA=|xA| =|-6| = 6

Similarly , the xy- plane represents all the points (x,y,0). Doing the same procedure , the distance is |z| . Then the point that is closest to this plane is B because

dB=|zB| =|-1| = 1

Also , for a point to lie in the xz-plane , has to be of the form (x,y,0) , that is zB=0 ( distance to the plane =0). Since neither A , B or C comply , then any of the points lie in this plane

the altitude of the hypotenuse of a right triangle divides the hypotenuse into segments of lengths 14 and 8. what is the length

lisov135 [29]

Answer:

B. $4\sqrt{7}$

Step-by-step explanation:

The right triangle altitude theorem states that the altitude of a right angled triangles formed on the hypotenuse is equal to the geometric mean of the 2 line segments it creates.

This can be represented as:

$h = \sqrt{(xy)}$
