What is the minimum value for y= 3cosx?

VashaNatasha [74]

Take the deritive
y'=-3sinx
find whre it equals 0
it equals 0 at -pi, 0, pi, etc
find whre it changes from negative to positive
at -0.5pi, the derivitive is positive
at 0.5pi, the deritivie is negative
changes from positive to negative at x=0
that means that the max values are at pi and -pi in 2pi intervals

-pi, pi, 3pi, 5pi,etc
the min y value is -3

so the minimum(s) are/is at (2aπ,-3) where 'a' is an integer

A new movie is released each year for 14 years to go along with a popular book series. Each movie is 2 minutes longer than the l

-Dominant- [34]

Answer:

B

Step-by-step explanation:

If you use the general equation for an arithmetic sequence,

$a_{n}=a_{1}+d(n-1)$ ,

where aₙ is the number of minutes for movie n,

a₁ is the length of the first movie in minutes, and

d is the difference between each movie, in minutes

Our sequence is this:

$a_{n}=70+2(n-1)$

If we want the length of the second movie (we already know the length of the first), we fill in n with 2:

$a_{2}=70+2(2-1)$

which gives us a length of 72. Now for the length of movie n = 3:

$a_{3}=70+2(3-1)$

which gives us a length of 74. Now for the length of movie n = 4:

$a_{4}=70+2(4-1)$

which gives us a length of 76. One more and I'm sure you'll notice the pattern:

$a_{5}=70+2(5-1)$

which gives us a length of 78. Now we will find the length of the 14th movie and add up by 2's all the way up to that number of minutes:

$a_{14}=70+2(14-1)$

which gives up a length of 96 minutes. We will add up by 2's from 70 to 96:

$70+72+74+76+78+80+82+84+86+88+90+92+94+96=1,162 min$
