Which recursive formula can be used to generate the sequence shown, where f(1) = 5 and n > 1?5,–1, –7, –13, –19, ...

Answers

Answer 1

Answer: the sequence of numbers decrease by 6 each time, so we can write:
f(1) = 5
f(2) = -1
f(3) = -7
f(1) - f(2) = 6
or:
f(2) = f(1) - 6
which means:
f(n + 1) = f(n) - 6

Answer 2

Answer:

Answer:

Step-by-step explanation:

the sequence of numbers decrease by 6 each time, so we can write:

f(1) = 5

f(2) = -1

f(3) = -7

f(1) - f(2) = 6

or:

f(2) = f(1) - 6

which means:

f(n + 1) = f(n) - 6

What is 7/8 x c for c=8

Answers

Answer:
7

Explanation:
We are given the equation:
$(7)/(8)$ * c

We want to get the value of the equation at c = 8.
Therefore, all we have to do is substitute c in the equation with 8 and solve as follows:
$(7)/(8)$ * 8

= $(7*8)/(8)$

The 8 in the numerator will be cancelled out with the 8 in the denominator leaving us with only the 7 as a solution

Hope this helps :)

Answer:

Value is 7

Step-by-step explanation:

We are given the expression, $(7)/(8)* c$ .

It is required to evaluate the expression for c= 8.

So, after substituting the value of c= 8 in the given expression, we get,

$(7)/(8)* c$ = $(7)/(8)* 8$ = 7

Hence, the value of the expression at c= 8 is 7.

Doris put $4000 in a 5year CD paying 6% interest compounded monthly. After 2 years, she withdrew all her money, and as an early withdrawal penalty, she paid back all the interest she made during the first year. How much money was Doris left with? Show your work.

Answers

Answer: Doris was left with $4216.93.

Step-by-step explanation:

Since we have given that

Principal amount = $ 4000

Rate of interest = 6%

He put $4000 in a 5 year CD paying 6% interest compounded monthly.

After 2 years, she withdrew all her money.

so, Amount after 2 years when it is compounded annually.

$A=4000(1+(6)/(12* 100))^(12* 2)\n\nA=4000(1+0.005)^(24)\n\nA=4000(1.005)^(24)\n\nA=\$4508.64$

As an early withdrawal penalty, she paid back all the interest she made during the first year.

$Interest=4000[(1+0.005)^(12)-1]\n\nInterest=\$246.71$

Amount left with Doris is given by

$\$4508.64-\$246.71\n\n=\$4261.93$

Hence, Doris was left with $4216.93.

for APEX it is going to be 4261.93
