Answer:

The graph could be a graph of the function:

      Option: B       B. F(x)=2\cdot (0.5)^x

Step-by-step explanation:

We know that for any exponential function of the type:

                            f(x)=ab^x

if b>1 then it represent a exponential growth

and if 0<b<1 then it represent a exponential decay.

Clearly from the graph given to us we could observe that it is a graph of a exponential decay.

Hence 0<b<1

Now we will check for each of the given options:

A)

F(x)=2\cdot (1.6)^x

Now as b=1.6>1

So, this function will represent a exponential growth.

Hence, option: A is incorrect.

C)

F(x)=2\cdot (7)^x

Now as b=7>1

So, this function will represent a exponential growth.

Hence, option: C is incorrect.

D)

F(x)=2^x

Now as b=2>1

So, this function will represent a exponential growth.

Hence, option: D is incorrect.

B)

F(x)=2\cdot (0.5)^x

Now as b=0.5<1 and also 0.5>0

So, this function will represent a exponential decay

             Hence, option: B is correct.

Given that the series kcoskt kº +2 k=1 converges, suppose that the 3rd partial sum of the series is used to estimate the sum of
3241004551 [841]

Answer:

c

Step-by-step explanation:

Given that:

\sum \limits ^{\infty}_{k=1} \dfrac{kcos (k\pi)}{k^3+2}

since cos (kπ) = -1^k

Then, the  series can be expressed as:

\sum \limits ^{\infty}_{k=1} \dfrac{(-1)^kk)}{k^3+2}

In the sum of an alternating series, the best bound on the remainder for the approximation is related to its (n+1)^{th term.

∴

\sum \limits ^{\infty}_{k=1} \dfrac{(-1)^{(3+1)}(3+1))}{(3+1)^3+2}

\sum \limits ^{\infty}_{k=1} \dfrac{(-1)^{(4)}(4))}{(4)^3+2}

= \dfrac{4}{64+2}

=\dfrac{2}{33}

For her college fund jenny's parents invested $5000 four years ago. the account has now reached $6312. what is the approximate a
Tasya [4]

Answer:

Rate = 6.56%

Step-by-step explanation:

Principal (P) = $5000

Interest (I) = $6312

Time (T) = 4 years

Rate (r) = ?

This question is involves simple interest and with the formula, we can easily plug in the values to find the rate.

S.I = P(1 + rt)

S.I = simple interest

P = principal

R = Rate

T = Time

6312 = 5000(1 + r*4)

6312 = 5000 + 5000*4r

6312 - 5000 = 20000r

1312 = 20000r

r = 1312 / 20000

r = 0.0656

Rate are calculated in percentage hence we'll multiply it by 100

R = 6.56%
