ira [324]3 years ago
6 0

Answer:

<u><em>Y =0</em></u>

Step-by-step explanation:

<u><em>The midline is the y value that runs straight through the middle of the wave. If you can picture the standard sine function graph. f(x) = Sin(x) reaches a maximum y = 1 and minimum y = -1 so the midline is y =0.</em></u>

bezimeni [28]

Answer:

Step-by-step explanation:

According to the first expression:

2(10-k): where,

2:shows the double amount of money which ELI has

10:shows the amount of money which ELI had at the starting.

k:shows the amount of money which is lost.

10-k:shows the amount of money which ELI has after losing some amount.

According to the second expression:

20-2k where,

20:shows the twice of initial amount.

k: is the amount of money which is lost

2k:s hows the twice of amount which is lost

20-2k: shows the amount of money which is left with ELI after his mom gave him some money....

Use the Ratio Test to determine whether the series is convergent or divergent.
natka813 [3]

Answer:

The series is absolutely convergent.

Step-by-step explanation:

By ratio test, we find the limit as n approaches infinity of

|[a_(n+1)]/a_n|

a_n = (-1)^(n - 1).(3^n)/(2^n.n^3)

a_(n+1) = (-1)^n.3^(n+1)/(2^(n+1).(n+1)^3)

[a_(n+1)]/a_n = [(-1)^n.3^(n+1)/(2^(n+1).(n+1)^3)] × [(2^n.n^3)/(-1)^(n - 1).(3^n)]

= |-3n³/2(n+1)³|

= 3n³/2(n+1)³

= (3/2)[1/(1 + 1/n)³]

Now, we take the limit of (3/2)[1/(1 + 1/n)³] as n approaches infinity

= (3/2)limit of [1/(1 + 1/n)³] as n approaches infinity

= 3/2 × 1

= 3/2

The series is therefore, absolutely convergent, and the limit is 3/2

Select the true statement plzzzz need help ASAPPPPP
xxMikexx [17]

Answer:

Correct choice is B

Step-by-step explanation:

All three functions are increasing when x is increasing. You can find values of each function when x is "enough large". For example, at x=100,

1. linear function: y=10\cdot 100=1,000.

2. exponential function: y=5^{100}\approx 0.8\cdot 10^{70}.

3. quadratic function: y=4\cdot 100^2+5\cdot 100=40,500.

As you can see,  when x approaches positive infinity, the exponential function will exceed both the linear and the quadratic functions.

Also you can use graphical method to get from the attached diagrams result. When x approaches positive infinity, the exponential function will exceed both the linear and the quadratic functions.

Correct choice is B.
