Consider the helix r(t)=⟨cos(7t),sin(7t),−1t⟩. Compute, at t=π6:

gogolik [260]

Consider the helix below:

$r(t)= (\cos(7t), \sin(7t), -t)$

We have to determine the value of helix at t = $\frac{\pi}{6}$

So, $r(\frac{\pi}{6})$

= $(\cos(\frac{7 \pi}{6}), \sin(\frac{7 \pi}{6}), -\frac{\pi}{6})$

Consider $\cos(\frac{7 \pi}{6}) = \cos(\pi + \frac{\pi}{6}) = - \cos (\frac{\pi}{6}) = \frac{-\sqrt3}{2}$

Consider $\sin(\frac{7 \pi}{6}) = \sin(\pi + \frac{\pi}{6}) = - \sin (\frac{\pi}{6}) = \frac{-1}{2}$

So, the value of helix $r(\frac{\pi}{6}) = (\frac{-\sqrt3}{2}, \frac{-1}{2}, \frac{- \pi}{6})$ .

A bookstore is deciding what price it should charge for a certain book. After research, the store finds that if the book's price

Wewaii [24]

Answer:

[130-5(13)] (13) = $845 max revenue.

Step-by-step explanation:

If the number of books sold = 130-5p then revenue will be (130-5p)p = -5p^2+130p

the maximum can be found by graphing or by the fact that the max will be -b/2a = -130/-10 = 13 dollars/book

[130-5(13)] (13) = $845 max revenue.

Serggg [28]

Answer:

That you answer

Step-by-step explanation:

Given 3x - 2 <2x +1 3x -2x 1 + 2 x <3 or x∈(−∞,3)

The lines y=3x−2 and y=2x+1 both will intersect at x=3

Clearly, the dark line shows the solution of 3x−2<2x+1.

The frequency of D3 is 146.83 Hz. What is the frequency of D5, which is two octaves above D3?

Vaselesa [24]

Answer: D

Frequency = 587.32 Hz

Step-by-step explanation:

One octave above has a frequency of 2 × 146.83 Hz = 293.66Hz (D4). Two octaves above has afrequency of 2 × 293.66 Hz = 587.32 Hz (D5)
