The constants 0.693 is the natural log of 2 and the constant 2.303 is the multiplicative factor of converting log of a number to the natural log of that same number.

<h3>What are 0.693 and 2.303 used for?</h3>

It follows from the task content that the calculation involves the use of the half-life of radioactive materials formula.

Hence, the constant 0.693 is the real number value of ln(2). Additionally, the constant 2.303 as used by convention is used to convert log value of a number x to its natural log value. Hence,. it follows that the relation which holds true is; ln(x) = 2.303 × log(x).

The conservation club has 32 members. There are 18 girls in the club.
butalik [34]
The answer is D. because if there is 32 total, and 18 of them are girls, that means that there are 14 boys . with the question asking for girl/boy ratio it would have to be 18/14 in that order . if you divide 18 and 14 by two, they simple down to 9/7 . making the answer D.

10. A 50-ft ladder leans against a building so that the base of the ladder is 15 feet from the
Hunter-Best [27]

By applying the trigonometry ratio, SOH, the angle that the ladder makes with the building is calculated as: 17.5°

<em><u>Recall:</u></em>

  • Trigonometry ratios that can be used to solve a right triangle are: SOH CAH TOA.
  • SOH represents: sin ∅ = Opp/Hyp
  • CAH represents: cos ∅ = Adj/Hyp
  • TOA represents: tan ∅ = Opp/Adj

The diagram attached below depicts the problem given.

∅ = x

Opp = 15 ft

Hyp = 50 ft

  • Thus, applying the trigonometry ratio, SOH, we have:

sin x = 15/50

x = sin^{-1}(15/50)

x = 17.5°

In conclusion, by applying the trigonometry ratio, SOH, the angle that the ladder makes with the building is calculated as: 17.5°
