Answer:

log3 4

Step-by-step explanation:

To write the two expressions as a single logarithm, we use the division law of logarithms since they are in the same base already.

Hence, log3 40 - log3 10 = log3 (40/10) = log3 4

Hamid is playing a trivia game with multiple choice questions. Each question has 2 correct answers among 5
goblinko [34]

The probability that Hamid guesses both answers correctly is 10%.

Since Hamid is playing a trivia game with multiple choice questions, and each question has 2 correct answers among 5 answer choices, and Hamid has no idea what the answers to a certain question are, so he needs to choose two different answers at random, to determine what is the probability that Hamid guesses both answers correctly the following calculation must be performed:

  • 2/5 x 1/4 = X
  • 0.4 x 0.25 = X
  • 0.1 = X
  • 0.1 x 100 = 10

Therefore, the probability that Hamid guesses both answers correctly is 10%.

Part A: Explain how to determine the value of the vertical translation, d, for the graph of g(x). (2 points)
Vinil7 [7]

Answer:

Part A: Up 9

Part B: Up 6

Step-by-step explanation:

Part A: The graph appears to be a cosine graph since it starts at a peak on the y-axis. Normally a cosine graph starts at (0,1). This graph begins at (0,10). It has been shifted up y a translation by 9.

Part B: Each trig equation has a basic structure f(x) = a sin (x+b) + k where:

  • a is the vertical stretch
  • b is the horizontal shift
  • k is the vertical shift

A vertical translation is a vertical shift and is represented by the value in k added outside of the function. In the equation f(x) = 2sin(θ + 120°) + 6, k = 6. The vertical translation is 6.
