What is the equation of the midline of the sinusoidal function?
WITCHER [35]
Answer: y = 0
Note: of course you don't need to type in the "y=" part as its already taken care of

----------------------------------------------------------

The highest point is when y = 5
The lowest point is when y = -5
Find the midpoint of those y values. Add them up: 5 + (-5) = 0
Then divide that result by 2: 0/2 = 0

The midpoint of 5 and -5 is 0. So the midline is y = 0
This is the center horizontal line that runs through the middle of the sinusoidal curve
The vertical distance from the midline to either the peak or valley is the same (in this case, 5) which is known as the amplitude

PLEASE PLEASE HELP WILL MARK BRAINLIEST
Rama09 [41]

Answer:

The answer is

\huge y = 3x + 21

Step-by-step explanation:

To find an equation of a line given the slope and a point we use the formula

y -  y_1 = m(x -  x_1)

where

m is the slope

( x1 , y1) is the point

From the question the point is (−5, 6) and slope = 3

The equation of the line is

y - 6  = 3(x + 5) \\ y - 6 = 3x + 15 \\ y = 3x + 15 + 6

We have the final answer as

y = 3x + 21

Hope this helps you

A furniture delivery truck leaves the store at 8 A.M. It travels 6 miles east, then 4 miles south, then 2 miles west and then 4
Dovator [93]

Answer:

It's 4 miles East from the store.

Step-by-step explanation:

6 miles east - 2 miles west = 4 miles East

Displacement for north and south should cancel out since they are equal to each other.
