What is the value of R
frutty [35]

Answer:

2.45 × 10^{6}

Step-by-step explanation:

using the rules of exponents

• \frac{a^{m} }{a^{n} } = a^{(m-n)}

• (a^m)^{n} = a^{mn}

evaluating the numerator

(3.8 × 10^{5})² = 3.8² × (10^5)^{2} = 14.44 × 10^{10}

R = \frac{14.44.10^{10} }{5.9.10^{4} }

  = \frac{14.44}{5.9} × \frac{10^{10} }{10^{4} }

  = 2.45 × 10^{6} ← to 2 dec. places

<u>AC</u><u> </u><u>i</u><u>s</u><u> </u><u>6</u><u>.</u><u>5</u><u> </u><u>cm</u>

Step-by-step explanation:

From trigonometric ratios:

\sin( \theta)  =  \frac{opposite}{hypotenuse}  \\

opposite » 3 cm

hypotenuse » AC

angle » 28°

\sin(28 \degree)  =  \frac{3}{AC}  \\  \\ AC =  \frac{3}{ \sin(28 \degree) }  \\  \\ AC =  \frac{3}{0.46}  \\  \\ AC = 6.5 \: cm
