📌 Une suite géométrique a un premier terme de 3 et une raison commune de 2. Quelle est la somme des 5 premiers termes ?

📌 La somme \(S_n\) des \(n\) premiers termes d’une suite géométrique est \(S_n = a \frac{r^n - 1}{r - 1}\).

📌 Ici, \(a = 3\), \(r = 2\), \(n = 5\).

📌 S_5 = 3 \frac{2^5 - 1}{2 - 1} = 3 \times (32 - 1) = 3 \times 31 = 93

📌 Si \( \sin \theta = \frac{3}{5} \) et \( \theta \) est dans le premier quadrant, trouvez \( \cos \theta \).

📌 Utilisez l’identité \(\sin^2 \theta + \cos^2 \theta = 1\).

📌 \left(\frac{3}{5}\right)^2 + \cos^2 \theta = 1 \implies \frac{9}{25} + \cos^2 \theta = 1 \implies \cos^2 \theta = 1 - \frac{9}{25} = \frac{16}{25}

📌 Puisque \(\theta\) est dans le premier quadrant, \(\cos \theta > 0\), donc \(\cos \theta = \frac{4}{5}\).

Let the number of thymine bases be \(x\). According to the ratio:
\frac{5}{3} = \frac{15}{x}
To solve for \(x\), cross-multiply:
5x = 15 \times 3
Calculate the right side:
5x = 45
Now, divide both sides by 5 to solve for \(x\):
x = \frac{45}{5} = 9
Thus, there are \(\boxed{9}\) thymine bases.
