1 answer:
uysha [10]3 years ago
6 0

Answer:

  • 1. a, 2. d, 3. b, 4. d, 5. a, 6. b, 7. d, 8. a, 9. d, 10. b

Step-by-step explanation:

Question 1

  • log3 9  = log 3 3² = 2

Question 2

  • log8 12 = log 12/log 8 = 1.19  

Question 3  

  • ln 7 = log 7 / log e = 1.95

Question 4  

  • log4 14 as a logarithm of base 3
  • log4 14 = log3 14/ log3 4

Question 5  

  • log6 5 as a logarithm of base 4
  • log6 5 = log4 5/ log4 6

Question 6

  • log4 (y − 9) + log4 3 = log4 81
  • log4 (3y - 27) = log4 81
  • 3y - 27 = 81
  • 3y = 108
  • y = 36

Question 7

  • 5 log2 k − 8 log2 m + 10 log2 n
  • log2 k^5 - log2 m^8 + log2 n^10 =
  • log2 (k^5n^10/m^8)

Question 8

  • 2 log x = log 36  log x^2 = log 36
  • x^2 = 36
  • x = √36
  • x = ± 6

Question 9  

  • 4 log12 2 + log12 x = log12 96  log12 16x = log12 96
  • 16x = 96
  • x = 6

Question 10

  • 2 log2 2 + 2 log2 6 − log2 3x = 3
  • log2 (4*36/3x) = 3
  • 48/x = 2^3
  • 48/x = 8
  • x = 48/8
  • x = 6

The radius of a circle is 6 meters. What is the area of a sector bounded by a 150 arc
just olya [345]

Answer:

47.14 m²

Step-by-step explanation:

Recall that the central angle of a full circle is 2π radians or 360°.  The area of the sector bounded by a 150° arc is the fraction

150°

------- times the area of the full circle (πr²):

360°

(15/36)π(6m)² = 0.417(3.14)(36 m² = 47.14 m²
