liberstina [14]

Answer: 15

<u>Step-by-step explanation:</u>

a₁ = ___, a₂ = 7, a₃ = ____, a₄ = 1575

a₁(r) = a₂

a₂(r) = a₃

a₃(r) = a₄

To get from a₂ to a₄, you have to multiply by r²

⇒ 7r² = 1575

⇒ r² = 225

⇒ r = 15

Convert the following into degree measure: 7pi/12

Alex787 [66]

Since we know that there are 180° in π radians, then, how many degrees are there in 7π/12 radians?

$\bf \begin{array}{ccll}
de grees&radians\\
\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\
180&\pi \\\\
d&\frac{7\pi }{12}
\end{array}\implies \cfrac{180}{d}=\cfrac{\quad \pi \quad }{\frac{7\pi }{12}}\implies \cfrac{180}{d}=\cfrac{\quad \frac{\pi}{1} \quad }{\frac{7\pi }{12}}
\\\\\\
\cfrac{180}{d}=\cfrac{\underline{\pi} }{1}\cdot \cfrac{12}{7\underline{\pi} }\implies \cfrac{180}{d}=\cfrac{12}{7}\implies \cfrac{180\cdot 7}{12}=d\implies 105=d$
