- 5/6x = 20

- 5 = 120x

x = - 5/120

x = - 1/24

2/3(x - 7) = - 2

2 = - 6(x - 7)

2 = - 6x + 42

6x = 42 - 2

6x = 40

x = 40/6

x = 20/3

x = 6  2/3

A cyclist rides his bike at a rate of
docker41 [41]
15 miles per hour right so anyways that will be split by the number of minutes per hour so first there are 60 mins in an hour so its 15 divided by 60 which is 0.25 next how many miles will the cyclist travel in 15 minutes so that would mean taking the answer from the above and multiply it by 15 since you need 15 min which is 3.75 miles in 15 min hope i helped rate brainiest so i can reach next lvl! :)

Questions, are all in picture, please solve
Andrews [41]

The function represents a <em>cosine</em> graph with axis at y = - 1, period of 6, and amplitude of 2.5.

<h3>How to analyze sinusoidal functions</h3>

In this question we have a <em>sinusoidal</em> function, of which we are supposed to find the following variables based on given picture:

  1. Equation of the axis - Horizontal that represents the mean of the bounds of the function.
  2. Period - Horizontal distance needed between two maxima or two minima.
  3. Amplitude - Mean of the difference of the bounds of the function.
  4. Type of sinusoidal function - The function represents either a sine or a cosine if and only if trigonometric function is continuous and bounded between - 1 and 1.

Then, we have the following results:

  1. Equation of the axis: y = - 1
  2. Period: 6
  3. Amplitude: 2.5
  4. The graph may be represented by a cosine with no <em>angular</em> phase and a sine with <em>angular</em> phase, based on the following trigonometric expression:

    cos θ = sin (θ + π/2)

If you choose a card at random from a well shuffled deck of 52 cards, what is the probability that the card chosen is not a hear
Vinvika [58]
Sample space ={13 H + 13 D + 13 S + 13 C} = 52 cards

P(getting one heart) = 13/52 = 1/4
P( getting NO heart) = 1-1/4 = 3/4 = 0.75
