Answer:

1. 6/15, or 2/5.

2. Apples cost more per pound.

Step-by-step explanation:

1. Brian reads 2/15 in 20 minutes, like we were told. It's easy to determine how much of his book he can read within an hour, by using the ratio 1/15:10. There's clearly 1/15 in 10 minutes, 2/15 in 20, 3/15 in 30, and so on. This would result in him reading 6/15's of his book in an hour.

2.

Peaches

0.6÷8/5 converts to .6 × 5/8. The result is .375.

Apples

1.75 ÷7/2 converts to 1.75×2/7. The result of this equation is .5, so therefore, the apples cost more per pound.

Explain how the graph of y = 2csc(x - pi/4) - 5 is related to the graph of the basic trigonometric function y = cscx.
Ymorist [56]

Answer: The distance between the min and max increased by a factor of 2, horizontally shifted to the right by \bold{\dfrac{\pi}{4}}, shifted down 5 units, and has a phase shift of \bold{\dfrac{\pi}{4}}

<u>Step-by-step explanation:</u>

The general form of a csc function is: y = A csc (Bx - C) + D  where

  • |A| is the amplitude (vertical stretch)
  • -A is a reflection over the x-axis
  • |B| is the horizontal stretch
  • -B is a reflection over the y-axis
  • C is a horizontal shift (left or right)
  • D is a vertical shift (up or down)

  • Period is \dfrac{2\pi}{B}
  • Phase Shift is \dfrac{C}{B}

In the given transformed graph y = 2 csc (x - \dfrac{\pi}{4}) - 5

  • A = 2   --> distance between the Min and max is 2(2) = 4
  • C = \dfrac{\pi}{4}  --> horizontally shifted to the right  \dfrac{\pi}{4} units
  • D = -5  --> shifted DOWN 5 units
  • Phase shift is \dfrac{\pi}{4}
