Each DVD storage case is about 1/5 inch thick. What will be the height in simplest form of 12 cases sold together?
Dominik [7]

Answer:

Height of the 12 cases will be = 2\frac{2}{5} inches.

Step-by-step explanation:

Thickness of each DVD storage case = \frac{1}{5} inches

Let number of DVD storage cases sold = x

Therefore, the height of cases sold will be represented by the expression  \frac{x}{5}

If the number of cases sold x = 12

So the height of the cases sold will be = \frac{12}{5} inches

                                                                = 2\frac{2}{5} inches

Therefore, the answer is 2\frac{2}{5} inches.

the graph of y= 6cos (x-2) - 3 is obtained by shifting the graph of y=6 cos x-3 horizontally 3 units to the right. true or false
Neporo4naja [7]

Answer:

false.

Step-by-step explanation:

Given the function g(x) = f(x − k), can be sketched f(x) shifted k units horizontally. if k is negative, the function is shifted k units to the left.

Given the function g(x) = f(x) + k, we can say that the function is translated vertically upwards k times. If k is negative, the function is translated vertically downwards k times.

In this case, the function is translated two units to the right and 3 units down because the number "-3" is negative.

So it's false. The graph is translated three units downwards and 2 units to the right.

Find the value of each expression using the given information cot∅=8, csc&lt;0<br> find sin ∅
Oksana_A [137]

9514 1404 393

Answer:

  sin(∅) = -√65/65

Step-by-step explanation:

The identities that relate the cotangent, the cosecant, and the sine are ...

  csc² = 1 +cot²

  sin = 1/csc

_____

For the given values, we find ...

  csc(∅)² = 1 +cot(∅)² = 1 +8² = 65

  csc(∅) = -√65 . . . . . . . . . . . . . . . . square root with attention to sign

  sin(∅) = -1/√65 = (-√65)/65
