1.Define phase shift. Could every sine function be expressed as a phase shifted cosine function? Explain.

Ann [662]

A phase shift is defined as the amount of x by which sinusoid is shifted to the left or right.

And yes, every sine function be expressed as a phase shifted cosine function:

sin(t)=cos(90-t)

Answer:

-80

Step-by-step explanation:

We have: -6 = $\frac{x}{8}$ + 4. In order to solve for x, we need to isolate it; in order to isolate x, we have to "undo" order of operations.

The regular order of operations is PEMDAS: parentheses, exponents, multiplication, division, addition, subtraction.

Here, since we're solving for x, we need to go backwards. So, first, subtract 4 from both sides:

-6 - 4 = $\frac{x}{8}$ + 4 - 4 ⇒ -10 = $\frac{x}{8}$

Then, multiply by 8 on both sides:

-10 * 8 = $\frac{x}{8}$ * 8 ⇒ x = -80

Thus, x = -80.

Hope this helps!

-40-2(3m+1/2)=7m-2 what does m equal

kherson [118]

Answer: $m$ = −3

Step-by-step explanation:

Hey there! I will give the following steps, if you have any questions feel free to ask me in the comments below.

Step 1: Expand.

−40 − 6 $m$ − 1 = 7 $m$ − 2

Step 2: Simplify −40 − 6 $m$ − 1 to −6 $m$ − 41.

−6 $m$ − 41 = 7 $m$ − 2

Step 3: Add 6 $m$ to both sides.

−41 = 7 $m$ − 2 + 6 $m$

Step 4: Simplify 7 $m$ − 2 + 6 $m$ to 13 $m$ − 2.

−41 = 13 $m$ − 2

Step 5: Add 2 to both sides

−41 + 2 = 13 $m$

Step 6: Simplify −41 + 2 to −39.

−39 = 13 $m$

Step 7: Divide both sides by 13.

− $\frac{39}{13}$ = $m$

Step 8: Simplify $\frac{39}{13}$ to 3.

−3 = m

Step 9: Switch sides.

$m$ = −3
