Plot another sin function of 20% higher frequency over the same range.

Mathematics

Ostrovityanka [42]3 years ago
4 0

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).

Answer:

Rode most in May, 133.2 miles

Rode least in March, 16.65

133.2 - 16.65 = 116.55

HELP!!!!!!!!! I DONT UNDERSTAND THIS
ValentinkaMS [17]

Answer:

x=86^{\circ}

y=94^{\circ}

z=54^{\circ}

Step-by-step explanation:

First, let's look at the largest triangle (two smaller triangles are combined) to solve for z. Since the sum of the angles in a triangle adds up to 180^{\circ}, we can write the equation:

20+74+32+z=180

z=180-126

z=54^{\circ}

Looking at the smaller triangle on the left, y (exterior angle) is the sum of the two opposite interior angles of the triangle on the left:

y=74+20

=94^{\circ}

Since x is the exterior angle of the triangle on the right, it is equivalent to the sum of the opposite interior angles of that triangle:

x=32+z

=32+54

=86^{\circ}

Hope this helps :)
