14.

The first, third and fifth number are even numbers. 2, 8, 12

And the second, forth and sixth numbers are odd numbers. 7, 3, 9

1. y = c + 2x

<span>c1= 2 (and subsequent c= next number in the series) and x is in </span>reducing order:

2 + 2x3 = 8

8 + 2x2 = 12

12 + 2x1 = 14

2. u = a (+-) 2(v).

a1=7 (and subsequent a= next number in the series) and v is in increasing order.

7 - 2x2 = 3

3 + 2x3 = 9

9 - 2x4 = 1

<span>the subsequent number is an even number, so it should be 14</span>

Money Flow The rate of a continuous money flow starts at $1000 and increases exponentially at 5% per year for 4 years. Find the

77julia77 [94]

Answer:

Present value = $4,122.4

Accumulated amount = $4,742

Step-by-step explanation:

Data provided in the question:

Amount at the Start of money flow = $1,000

Increase in amount is exponentially at the rate of 5% per year

Time = 4 years

Interest rate = 3.5% compounded continuously

Now,

Accumulated Value of the money flow = $1000e^{0.05t}$

The present value of the money flow = $\int\limits^4_0 {1000e^{0.05t}(e^{-0.035t})} \, dt$

= $1000\int\limits^4_0 {e^{0.015t}} \, dt$

= $1000\left [\frac{e^{0.015t}}{0.015} \right ]_0^4$

= $1000\times\left [\frac{e^{0.015(4)}}{0.015} -\frac{e^{0.015(0)}}{0.015} \right]$

= 1000 × [70.7891 - 66.6667]

= $4,122.4

Accumulated interest = $e^{rt}\int\limits^4_0 {1000e^{0.05t}(e^{-0.035t}} \, dt$

= $e^{0.035\times4}\times4,122.4$

= $4,742

As part of a survey, 150 students were asked to name their favorite class. 50 points

disa [49]

A:40%
If you put 60 over 150 and x(percent of students) over 100 and cross multiply 100 and 60, you will get 6000. You then divide that by 150 which leaves you with 40 as x and 40 over 100 is 40%.
