PLEASE HELP NEED THIS ANSWERED CORRECTLY
Helen [10]

f(3) = 1.9

Solution:

Given function:

$f(x)=\frac{14}{7+2 e^{-0.6 x}}

To find f(3):

Substitute x = 3 in the given function.

$f(3)=\frac{14}{7+2 e^{-0.6 (3)}}

$f(3)=\frac{14}{7+2 e^{-1.8}}

Let us first simplify 2e^{-1.8}.

Apply exponent rule: a^{-b}=\frac{1}{a^{b}}

$ 2e^{-1.8}=2\frac{1}{e^{1.8}}$

The value of e^{1.8}=6.04964. (using calculator)

$\frac{2}{e^{1.8}}=\frac{2}{6.04964}=0.33059

2e^{-1.8}=0.33059

Substitute this value in f(3).

$f(3)=\frac{14}{7+0.33059}

$f(3)=\frac{14}{7.33059}  

$f(3)=1.90980

f(3) = 1.9

Hence the value of f(3) is 1.9.

An account has $26,000 after 15 years. The account received 2.3 percent interest compounded continuously. How much was deposited
Leya [2.2K]

The intital amount deposited was  $18485.82.

<h3>How to find the compound interest?</h3>

If n is the number of times the interested is compounded each year, and 'r' is the rate of compound interest annually, then the final amount after 't' years would be:

a = p(1 + \dfrac{r}{n})^{nt}

An account has $26,000 after 15 years. The account received 2.3 percent interest compounded continuously.

A = 26000

R = 0.02.3

a = p(1 + \dfrac{r}{n})^{nt}

26000 = p(1 + \dfrac{2.3}{100})^{15}\\\\26000 = p \times 1.4064\\\\\P= 18485.82

Therefore, the intital amount deposited was  $18485.82.

Henry can write 5 pages of his novel in 3 hours. At this rate, how many pages can Henry write in 8 hours?
Anna007 [38]

Step-by-step explanation:

3 hours =5 pages

8 hours =x

Cross multiplying

3x=5×8

3x=40

Dividing both sides by 3

3x/3=40/3

x=13.33

To the nearest whole number Henry will write 13 pages in 8 hours
