The intersection of a plane and a three-dimensional figure results in a triangular cross-section is a triangular pyramid.
What is a cross-section?A solid's cross-section is a plane figure formed when the solid intersects another plane. As a result, the cross-section of an object is an infinitesimal "slice" of a solid, and it can vary depending on how the slicing plane is oriented. A sphere's cross-section is always a disk, although a cube's cross-section can be square, hexagonal, or another shape.
In these types of three-dimensional geometrical problems imagination of the figures is very crucial.
Now, Think of the plane as a very very thin sheet cutting a triangular pyramid parallel to its base will have exactly the same cross-section as its base and we know a triangular pyramid has a triangular base.

Assuming that (-2)(-7) and 4 + (-18) are equal.
⇒ (-2)(-7) = 4 + (-18)Using the property [-x × -y = x × y = xy]:
⇒ (-2)(-7) = 4 + (-18) ⇒ (2)(7) = 4 + (-18)Using the property [x + (-a) = x - a]:
⇒ (2)(7) = 4 + (-18)⇒ (2)(7) = 4 - 18⇒ 14 = -14 (False)Option B)Assuming that (2)(7) and 4 + 18 are equal.
⇒ (2)(7) = 4 + 18⇒ 14 = 22 (False)Option C)
Assuming that (–2)(7) and 18 + (–4) are equal.
⇒ (-2)(7) = 18 + (-4)Using the property [-x × y = -xy]:
⇒ (-2)(7) = 18 + (-4)⇒ (-)(2)(7) = 18 + (-4)⇒ -14 = 18 + (-4)Using the property [x + (-a) = x - a]:
⇒ -14 = 18 + (-4)⇒ -14 = 18 - 4⇒ -14 = 14 (False)Option D)
Assuming that (2)(-7) and 4 - 18 are equal.
⇒ (2)(-7) = 4 - 18Using the property [-x × y = -xy]:
⇒ (-)(2)(7) = 4 - 18⇒ -14 = 4 - 18⇒ -14 = -14 (True)Therefore, Option D is correct.

A maple tree is 6 meters tall. Its shadow is 8 meters long. Close by, there is a streetlamp
that is 9 meters tall. How long is the streetlamp's shadow?
Write your answer as a whole number or a decimal. Do not round.
meters
Answers
Answer:
12 meters
Step-by-step explanation:
The assumption regarding shadow lengths is that they are proportional to height at any given place and time.
__
Here, the streetlamp is 9/6 = 3/2 times as tall as the tree, so we expect its shadow to be 3/2 times the length of the tree's shadow.
(3/2)(8 m) = 12 m
The streetlamp's shadow is 12 meters long.

Concepts
The circumference of a circle is the distance around it, or the perimeter of the circle. The formula to find the circumference is 2πr, where r = radius.
Application
We're given the radius as 9 cm, and we have to find the circumference of the circle using π as 3.14. Let's use the formula 2πr to solve for this.

State the x and y intercepts of 2x+5y=10
PLEASE
Answers
So 2x+5y=10, is the given equation and then it becomes 2x+5(0)=0, once you plug in y=0.
which leads to 2x+0=10 once you multiply 5 and 0.
So then simplify to get 2x=10
divide both sides by 2 to eliminate 2x so it's 2x/2=10/2.
Then solve for x for both sides so it will be x=5.
The x intercept will be (5,0).
For the y intercept first you plug x=0 and solve for x
So the equation is 2x+5y=10 but now becomes 2(0)+5y=10.
Next multiply the 2 and 0 which becomes 0+5y=10.
Simplify the equation so now it's 5y=10.
Next is to divide both sides by 5 to isolate the y so 5y/5=10/5
Finally y=2
so the y intercept would be (0,2).

Answer:
8x-9
Step-by-step explanation:
You have to combine like terms in order to simplify this problem.
The like terms you have are 5x, and 3x. If you add 5x+3x, you get 8x.
Now, you do nothing with the 9 because there is nothing to combine it with. For example, if your problem was 5x+3x-9+10, you combine 5x and 3x to get 8x, but now with the 9, you keep the subtraction symbol so it is 10-9, (think of it as -9), and when you finish that, you get 1. Now there are no more symbols so you add, 8x+1.

Answers
Answer:
V = π(2.5)²(7)
Step-by-step explanation:
Given:
A flower vase is in the shape of a cylinder and has a diameter of 5 inches and a height of 7 inches.
To Find:
which equation could be used to determine the volume, in cubic inches, of the vase?
Solve:
Formula for cylinder volume: Volume = πr²h
Where,
h represents the height of the cylinder
r represents the radius of the cylinder.
π is a constant whose value is 3.14
Knowing that:
Diameter = 5 in
Height = 7 in
Radius = 2.5 {Radius is half of diameter so 5/2 = 2.5}
Thus, a equation could be use is:
V = π(2.5)²(7)
