If you would like to know the page that Casey start on at 3:30 P.M., you can calculate this using the following steps:

8:00 P.M. - <span>5:30 P.M. = 2:30
280 - 160 = 120 pages

</span><span>5:30 P.M. - 3:30 P.M. = 2:00

2:30 = 150 minutes ... 120 pages
2:00 = 120 minutes ... x pages = ?

150 * x = 120 * 120
x = 120 * 120 / 150
x = 96 pages

160 pages - 96 pages = 64

Casey started on page 64.</span>

Given:
3:30 - 5:30 = page 160
5:30 - 8:00 = page 280

280 - 160 = 120
8:00 - 5:30 = 2.5 hours or 5 half hours 
120 / 5 half hours  =  24 pages every half hour or 30 minutes

3:30 - 5:30 = 2 hours or 4 half hours
24 * 4 = 96 pages

160 - 96 = 64

P Casey was on page 64 at 3:30 p.m.

Select the functions that have identical graphs.
Elan Coil [88]

Answer:

c. 1 and 3

Step-by-step explanation:

To quickly solve this problem, we can use a graphing tool or a calculator to plot each equation.

Please see the attached image below, to find more information about the graph

s

The equations are:

1) y = sin (3x + π/6)

2) y = cos (3x - π/6)

3) y = cos (3x - π/3)

Looking at the graphs, we can see that the identical ones

are equations one and three

Correct option:

c. 1 and 3
