What is the simplified form of the following expression? 5√8-√18-2√2

Romashka [77]

Answer:

Option (B) is correct.

To prove

As given the epression in the question is given by

$= 5\sqrt{8} - \sqrt{18} - 2 \sqrt{2}$

Now simplify the above

Terms are written as

$\sqrt{8} = \sqrt{2\times 2\times 2} = 2 \sqrt{2}$

$\sqrt{18} = \sqrt{3\times 3\times 2} = 3 \sqrt{2}$

Put in the above expression.

$= 5\times 2 \sqrt{2} -3 \sqrt{2} - 2 \sqrt{2}$

$= 10 \sqrt{2} -5 \sqrt{2}$

$=5 \sqrt{2}$

$Therefore\ the\ expression\ 5\sqrt{8} - \sqrt{18} - 2 \sqrt{2}\ is\ equivalent\ to\ 5 \sqrt{2} .$

The population of a certain city was 112,000 in 1998, and the observed relative growth rate is 4% per year. (a) Find a function

Zanzabum

Answer:

See Explanation

Step-by-step explanation:

Now;

From;

P=Poe^kt

Where;

P = population at time=t

Po = population initially present

k = growth rate

t = time taken

a) The function is;

P= 112,000e^0.04t

b) In the year 2004, the population will be

P= 112,000e^0.04(6)

P= 142380

c) 200,000 =112,000 e^0.04t

200,000/112,000 = e^0.04t

1.786 = e^0.04t

ln 1.786 = ln e^0.04t

ln 1.786= 0.04t

t = ln 1.786/0.04

t = 14.5 years
