well, the volume of that triangular prism will just be the area of the triangle times the length.

now, what's the area of that triangular face?  well, let's say it has a base of "b" and a height of 3, whilst the prism has a length of 6, Check the picture below.

\stackrel{\textit{triangle's area}}{\cfrac{1}{2}(b)(3)}\stackrel{\textit{prism's length}}{(6)}~~ = ~~4\frac{1}{2}\implies 9b=\cfrac{9}{2}\implies b=\cfrac{9}{18}\implies b=\cfrac{1}{2}

I think of a number multiply it by 2, subtract 5 and multiply the result by 2
zalisa [80]
Call our original number n. Then here's what we did in an equation:
(n*2-5)*2=2

We can solve this for n:
n*2-5=1
n*2=6
n=3

The entrepreneur had a well-deserved reputation for
jekas [21]

The entrepreneur had a well-deserved reputation for <u>prescience</u> having accurately anticipated many changes unforeseen by established business leaders.

The correct option is A.

The definition of prescience is understanding something before it happens, as followed by the word anticipate, which also means prediction, thus all other options are eliminated, such as foreknowledge.

<h3>What is prescience?</h3>

prescience is the supposed psychic experience of seeing or becoming intimately aware of future events. There is no accepted scientific proof that precognition exists, and it is largely regarded as pseudoscience.

<h3>How do you use prescience?</h3>

He foresaw their reaction with incredible foresight. Her foresight as an investor is remarkable. These sample sentences were automatically compiled from different internet news sources to reflect current use of the word 'prescience.'

Abby used the law of cosines for TriangleKMN to solve for k.
torisob [31]

Answer:

  m∠K = 37° and n = 31

Step-by-step explanation:

A lot of math is about matching patterns. Here, the two patterns we want to match are different versions of the same Law of Cosines relation:

  • a² = b² +c² -2bc·cos(A)
  • k² = 31² +53² -2·31·53·cos(37°)

<h3>Comparison</h3>

Comparing the two equations, we note these correspondences:

  • a = k
  • b = 31
  • c = 53
  • A = 37°

Comparing these values to the given information, we see that ...

  • KN = c = 53 . . . . . . . . . . matching values 53
  • NM = a = k . . . . . . . . . . . matching values k
  • KM = b = n = 31 . . . . . . . matching values 31
  • ∠K = ∠A = 37° . . . . . . . matching side/angle names

Abby apparently knew that ∠K = 37° and n = 31.

__

<em>Additional comment</em>

Side and angle naming for the Law of Sines and the Law of Cosines are as follows. The vertices of the triangle are labeled with single upper-case letters. The side opposite is labeled with the same lower-case letter, or with the two vertices at either end.

Vertex and angle K are opposite side k, also called side NM in this triangle.
