Answer:

a) Sinusoidal functions are y = a sin [b(x-h)] + k    (or)                                        

y = a cos [b(x-h)] + k

Where a is amplitude a= (max-min)/2=(16-2)/2=7

period p= 2π/b

            b=2π/30

            Horizontal transformation to 10 units right h=10

            k= (max+min)/2=(16+2)/2=9

h = 7 cos [π/15(t-10)]+ 9

b) t=10min=600 sec

substitue in the above equation

h=5.5m

What is the area of each piece of paper that Jodi is cutting out
Reptile [31]
The simplest (and most commonly used) area calculations are for squares and rectangles. To find the areaof a rectangle multiply its height by its width. For a square you only need to find the length of one of the sides (as each side is the same length) and then multiply this by itself tofind the area.

Darya [45]

Answer:

718\ min

Step-by-step explanation:

Let

x ----> the number of minutes

y ----> the total charge in dollars

we know that

For x>700 min

y=0.45x+40

so

For y=48.10

substitute

48.10=0.45x+40

Multiply by 100 both sides

4,810=45x+4,000 ----> equation without decimals

solve for x

45x=4,810-4,000\\45x=810\\x=18\ min

To find out the total minutes we need to sum

18\ min+700\ min=718\ min
