Give three real-world examples of rectangular prisms.

Mathematics

barxatty [35]3 years ago
5 0

Answer:

Rectangular Prisms: Most Skyscrapers, a cardboard box, and a book

Triangular Prism: Camping Tent and Slice of Cake.

Step-by-step explanation:

Rectangular Prisms: Most skyscrapers are rectangular prisms because they have 4 very long sides and 2 smaller sides. A cardboard box can be a rectangular prism for the same reasons. And a book, even though it doesn't look like a normal one, it still is a rectangular prism.

Triangular Prism: A Camping tent has 2 short triangular sides and 3 rectangular sides. A slice of cake has 2 tall triangles and 3 other rectangular sides. These fall under the category of a triangular prism.

Which congruence theorem can be used to prove<br> ABR = RCA?
vivado [14]

Answer: The HL Theorem can be used to prove ABR ≅ RCA because both triangles share the same hypotenuse and a leg. The HL theorem states that If the hypotenuse and one leg of a right triangle are congruent to the hypotenuse and one leg of another right triangle, then the triangles are congruent.

(05.06)A chocolate bar measures 50 mm wide, 90 mm long, and 3 and 1 over 2 mm high. Will’s Wrapping Company is making a wrapper
grandymaker [24]
The surface area of a rectangular prism is always:

A=2(xy+xz+yz), where x, y, and z are the three dimensions of the prism.

A=2(50*90+50*3.5+90*3.5)

A=2(4500+175+315)

A=2(4990)

A=9980 mm^2

How do I solve the equation in an interval from 0 to 2π ? 9 cos 2t = 6​
Ivahew [28]

9\cos(2t)=6\implies\cos(2t)=\dfrac23

Using the fact that cos is 2π-periodic, we have

\cos(2t)=\dfrac23\implies2t=\cos^{-1}\left(\dfrac23\right)+2n\pi

That is, \cos(\theta+2n\pi)=\cos\theta for any \theta and integer n.

\implies t=\dfrac12\cos^{-1}\left(\dfrac23\right)+n\pi

We get 2 solutions in the interval [0, 2π] for n=0 and n=1,

t=\dfrac12\cos^{-1}\left(\dfrac23\right)\text{ and }t=\dfrac12\cos^{-1}\left(\dfrac23\right)+\pi
