Find the unknown side lengths and angle measures.
seropon [69]

Answer:

Step-by-step explanation:

<em>m∠D</em> = 90° - 51° = <em>39°</em>

sin E = \frac{DE}{DF} ⇒ DE = DF × sin E

<em>DE</em> = 18 sin51° ≈ <em>14.0 ft.</em>

cos E = \frac{EF}{DF} ⇒ EF = DF × cos E

<em>EF</em> = 18 × cos51° ≈ <em>11.3 ft.</em>

Plot another sin function of 20% higher frequency over the same range.
Ostrovityanka [42]

Step-by-step explanation:

The frequency of sine function is given by the number of periods in a given range. For example:

  • Frequency for sin(x) is 1 in the interval [0,2\pi].

This means that, if we want another sine function with frequency 20% higher, we need that function to have a frequency of 1.2 in the interval [0,2\pi].

To be easier to see we will consider interval [0,10\pi] instead of [0,2\pi]. In this interval sin(x) has 5 periods, therefore our new sine function should have 6 periods.

Finally, as we can see in the graph, the function sin(\frac{6}{5}x ) (in blue) has a frequency 20% higher than sin(x) (in red). This can be easily seen counting the number of periods between 0 and 10\pi for both functions. 5 for sin(x) and 6 for sin(\frac{6}{5} x).
