Answer:

b(4) = -8

Step-by-step explanation:

We are to find the 4th term.

n = 4

b(n) = 1(-2)ⁿ⁻¹

b(4) = 1(-2)⁴⁻¹

b(4) = 1(-2)³

b(4) = 1(-8)

b(4) = -8

What is 4x-5/3+2x=7+2/9x+2
ch4aika [34]

Simplifying the expression gives 36x^2 - 82x - 10 = 0

<h3>How to simplify the expression</h3>

Given the expression;

4x-5/3+2x=7+2/9x+2

\frac{4x - 5}{3 + 2x} = \frac{9}{9x + 2}

Cross multiply

4x - 5( 9x + 2) = 9 (3 + 2x)

Expand the bracket

36x^2 + 8x - 45x - 10 = 27x + 18x

Collect like terms

36x^2 + 8x - 45x - 27x - 18x = 0

Add the like terms

36x^2- 82x - 10 = 0

Thus, simplifying the expression gives 36x^2- 82x - 10 = 0

Please help!!! ASAP someone please
murzikaleks [220]

Answer:

0.31 yr

Step-by-step explanation:

The formula for interest compounded continuously is

FV = PVe^{rt}

FV = future value, and

PV = present value

If FV is twice the PV, we can calculate the doubling time, t

\begin{array}{rcl}2 & = & e^{rt}\\\ln 2 & = & rt\\t & = & \dfrac{\ln 2}{r} \\\end{array}

1. Brianna's doubling time

\begin{array}{rcl}t & = & \dfrac{\ln 2}{0.065}\\\\& = & \textbf{10.663 yr}\\\end{array}

2. Adam's doubling time

The formula for interest compounded periodically is

FV = PV\left (1 + \dfrac{r}{n} \right )^{nt}

where

n = the number of payments per year

If FV is twice the PV, we can calculate the doubling time.

\begin{array}{rcl}2 & = & \left (1 + \dfrac{0.0675}{4} \right )^{4t}\\\\&= & (1 + 0.016875 )^{4t}\\& = & 1.016875^{4t}\\\ln 2& = & 4 (\ln 1.01688)\times t \\& = & 0.066937t\\t& = & \dfrac{\ln 2}{0.066937}\\\\& = & \textbf{10.355 yr}\\\end{array}

3. Brianna's doubling time vs Adam's

10.663 - 10.355 = 0.31 yr

It would take 0.31 yr longer for Brianna's money to double than Adam's.
