See the graphs

<h2>Explanation:</h2>

First Case:

Here we have the following function:

h(x)=2sin(2x)-3

In order to graph this function, first let's take:

f(x)=sin(x)

Step 1. Compress horizontally this function by 1/2, so it becomes:

f_{1}(x)=sin(2x)

Step 2. Stretch vertically this function, so it becomes:

f_{2}(x)=2sin(2x)

Step 3. Shift the graph of the function three units down.

f_{2}(x)=2sin(2x)-3

Second Case:

Applying a similar method, we get:

Step 1. Compress horizontally this function by 1/2, so it becomes:

Step 2. Stretch vertically this function, so it becomes:

Step 3. Shift the graph of the function tow units down.

Finally, the graphs are shown below.

Which expressions correctly show "the sum of the product of 3 and 8 and the product of 12 and 2"? Select two that are correct. *
Degger [83]

Answer:

The two correct expressions are:

  • (12 × 2) + (3 × 8)
  • (3 × 8) + (12 × 2)

Step-by-step explanation:

Let 'a' and 'b' be the two numbers.

When we say the product of 'a' and 'b', it

  • algebraically means: a × b

Let 'c' and 'd' be the two numbers.

When we say the product of 'c' and 'd', it

  • algebraically means: c × d

And when we say the sum of the product of 'a' and 'b' and the product of 'c' and 'd', it algebraically means:

(a × b) + (c × d)

or

(c × d) + (a × b)

as

(a × b) + (c × d) = (c × d) + (a × b)

So when we say "the sum of the product of 3 and 8 and the product of 12 and 2".

It algebraically means:

(12 × 2) + (3 × 8)

or

(3 × 8) + (12 × 2)

as

(12 × 2) + (3 × 8) = 24 + 24      ∵ 12 × 2 = 24, 3 × 8 = 24

                           = 48

(3 × 8) + (12 × 2) = 24 + 24      ∵  3 × 8 = 24, 12 × 2 = 24,

                          = 48

Therefore, the two correct expressions are:

  • (12 × 2) + (3 × 8)
  • (3 × 8) + (12 × 2)

Here are the first four terms of a number sequence.
AleksAgata [21]
8,14,20,26

8 to 14 is 6
14 to 20 is 6
20 to 26 is 6


The next term will be 26 + 6 = 32

Because there is a gap of 6 between each number
