patriot [66]

Answer:

  • x = 14

Step-by-step explanation:

<u>Direct variation equation:</u>

  • y = kx, where k is constant of variation

<u>Given:</u>

  • 96 = 8k
  • k = 96/8
  • k = 12

<u>The equation is:</u>

  • y = 12x

<u>Find the value of x when y = 168:</u>

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
