If the instructions for a problem ask you to use the smallest possible domain to completely graph two periods of y = 5 + 3 cos 2

(x - pi divided by three), what should be used for Xmin and Xmax? Plz explain why because this question is seriously confising me.

Hello,

y=5+3*cos (2(x-π/3))

The function is periodic with periode=2π.


-1<=cos (2(x-π/3))<=1
==>-1*3<=3*cos (2(x-π/3))<=3*1
==>5-3<=5+3cos(2(x-π/3))<=5+3
==>2<= y<=8

In Speed Study Number 1, we looked at two cars traveling the same distance at different speeds on city streets. Car "A" traveled
MAVERICK [17]

Answer:

b-about 5 minutes

Step-by-step explanation:

For an object in uniform circular motion (=moving at constant velocity), the time taken to cover a certain distance is given by:

t=\frac{d}{v}

where

d is the distance covered

v is the speed of the object

In this problem we have:

d = 10 miles is the distance covered by both cars

Car A travels at a speed of

v_A=35 mi/h

So the time it takes is

t=\frac{10}{35}=0.286 h \cdot 60 \frac{min}{h}= 17.2 min

Car B travels at a speed of

v_B=45 mi/h

So the time it takes is

t'=\frac{d}{v_B}=\frac{10}{45}=0.222 h \cdot 60 \frac{min}{h}=13.3 min

So the difference in time is

\Delta t = t-t'=17.2 min - 13.3 min \sim 4 min

So, the closest answer is

b-about 5 minutes
