This question is Incomplete

Complete Question

Recall the hurricane relief fund context from the previous investigation. Bob set up a hurricane relief donation fund and started it off by donating $ 35 . Instead of tripling in value each day, suppose it doubled in value each day

Complete the following table showing the account values at the end of each day.

Number of days since the initial investment, n Amount (in dollars) in the relief account, A

0 1 2 3 4

Answer:

Number of days(n) = Amount (in dollars) in the relief account(A)

0 = $35

1 = $70

2 = $140

3 = $280

4 = $560

Step-by-step explanation:

The formula for doubling time

P(t) = Po(2)^t/k

Where P = Amount after time t

Po = Initial Amount

t = number of days

k = Frequency at which it doubles

For 0 days

t = 0, k = 1, P(o) = $35

P(t) = Po(2)^t/k

P(0) = $35(2)^0/1

= $35(2)⁰

= $35 × 1

= $35

For 1 day

t = 1, k = 1 , P(0) = $35

P(t) = Po(2)^t/k

P(0) = $35(2)^1/1

= $35(2)¹

= $35 × 2

= $70

For 2 days

P(t) = Po(2)^t/k

t = 2, k = 1, P(0) = $35

P(0) = $35(2)^2/1

= $35(2)²

= $35 × 4

= $140

For 3 days

P(t) = Po(2)^t/k

t = 3, k = 1

P(0) = $35(2)^3/1

= $35(2)³

= $35 × 8

= $280

For 4 days

P(t) = Po(2)^t/k

t = 3, k = 1, P(0) = $35

P(0) = $35(2)^5/1

= $35(2)⁴

= $35 × 16

= $560

A stadium asked for $760,000 for naming rights. During a bidding war for the stadium naming rights, one company bid 7% more than
alex41 [277]

Answer:

\$\ 829464

Step-by-step explanation:

Bid of first company:

Bid is 7\% more

7\% of 760000=\frac{7}{100}\times760000=53200

Bid of first =760000+53200=813200

Bid of second company:

Bid of second is 2\% greater than that of first

2\% of first bid =\frac{2}{100}\times 813200=16264

Hence Bid of second company =813200+16264=829464

Suppose a1=12−12,a2=23−13,a3=34−14,a4=45−15,a5=56−16. a) Find an explicit formula for an: . b) Determine whether the sequence is
lorasvet [3.4K]

I'm going to assume you meant to write fractions (because if a_n are all non-negative integers, the series would clearly diverge), so that

a_1=\dfrac12-\dfrac12

a_2=\dfrac23-\dfrac13

a_3=\dfrac34-\dfrac14

and so on.

a. If the pattern continues as above, we would have the general term

a_n=\dfrac n{n+1}-\dfrac1{n+1}=\dfrac{n-1}{n+1}

b. Note that we can write a_n as

a_n=\dfrac{n-1}{n+1}=\dfrac{n+1-2}{n+1}=1-\dfrac2{n+1}

The series diverges by comparison to the divergent series

\displaystyle\sum_{n=1}^\infty\frac1n

Literal Equations: d + 3n = 1, for n
slega [8]
D + 3n = 1        Subtract d from both sides
      3n = 1 - d   Divide both sides by 3
        n = \frac{1 - d}{3}
