The given function is
The general form of the cosine function is
a is the amplitude
2pi/b is the period
c is the phase shift
d is the vertical shift
By comparing the two functions
a = 4
b = pi
c = 0
d = 1
Then its period is
The equation of the midline is
Since the maximum is at the greatest value of cos, which is 1, then
Since the minimum is at the smallest value of cos, which is -1, then
Then substitute them in the equation of the midline
The answers are:
Period = 2
Equation of the midline is y = 1
Maximum = 5
Minimum = -3
Answer:
Step-by-step explanation:
2.6 * 10^9
-------------
1.3 * 10^2
2.6 / 1.3 = 2 and 10^9 / 10^2 = 10^7
so the answer is 2 * 10^7
Answer:
See below
Step-by-step explanation:
to find the slope of a line you need to use the formula y1-y2/x1-x2
2. the points are (3,2) and (1,-2)
y1-y2 = 2--2 = 4
x1-x2 = 3-1 = 2
4/2 is the same as 2
3. (1,4) and (2,1)
4-1=3
1-2=-1
3/-1 = -3
the slope is -3
4. (6,5) and (3,1)
5-1 = 4
6-3 = 3
4/3
the slope is 4/3
Answer:
The table will be:
x y=x+1
1 2
2 3
3 4
4 5
5 6
The graph is shown in figure attached.
Step-by-step explanation:
We need to create table and graph the expression: 
Table is made, such that we take value of x and find value of y
You can take any values of x from negative values to positive values. I am taking values of x: 1,2,3,4,5 and find value of y.
So our table will be:
x y=x+1
1 2
2 3
3 4
4 5
5 6
Now, we will plot these value on the graph. x values will be on x-axis and corresponding y-values will be on y-axis.
The graph is shown in figure attached.
