HELP
Answer:
Step-by-step explanation:
The shortest distance d, of a point (a, b, c) from a plane mx + ny + tz = r is given by:
--------------------(i)
From the question,
the point is (5, 0, -6)
the plane is x + y + z = 6
Therefore,
a = 5
b = 0
c = -6
m = 1
n = 1
t = 1
r = 6
Substitute these values into equation (i) as follows;
Therefore, the shortest distance from the point to the plane is
Answer:
20/19
Step-by-step explanation:
y2-y1/x2-x1
= 8-3/5-1/4
=20/19
I don’t see a picture so I can’t exactly answer this. Sorry
I saw the image that should have been included in this problem.
It was a rectangular prism. It can also be identified as a right prism because its bases are aligned one directly above the other and its lateral faces are rectangular.
The image has the following measurements:
length = 7 inches
width = 5 inches
height = 4 inches
volume = length * width * height
v = 7 in * 5 in * 4 in
v = 140 in³ Choice B i believe.
