Step-by-step explanation:

Since b2 is certainly positive, that means a2 is certainly negative, which is impossible. √−1=i is an imaginary number, not lying anywhere on the real number line. Therefore as others have said, it is neither rational nor irrational in the usual senses of those words.

The population of a coty is 100,000 and the annual growth rate is 4.2%. Write an equation to model the population y after x year

Andrews [41]

Answer: $1,00,000(1+0.042)^x$

Step-by-step explanation:

Given

The initial population of a city is $P_o=1,00,000$

The annual growth rate is $4.2\%$

after 1 year it is

$\Rightarrow P_1=1,00,000+4.2\%\times 1,00,000\\\Rightarrow P_1=1,00,000(1+0.042)$

after 2 years, it is

$\Rightarrow 1,00,000(1+0.042)+4.2\%\times 1,00,000(1+0.042)\\\Rightarrow 1,00,000(1+0.042)^2$

after x years it is

$\Rightarrow P_x=1,00,000(1+0.042)^x$

Can someone help me please, thanks

9966 [12]

Answer:

B. x ≥ 2

Explanation:

hey there,

< 54-10x ≤ 20+7x

This is kind of simplified as if it was an equation with "=". First, put all the "x"s to one side.

54-10x-7x ≤ 20

Put all the regular numbers to the other side.

-10x-7x ≤ 20-54

Continue simplifying:

-17x ≤ -34

When finishing up this to try to find "x", you are going to change the sign to the opposite (since here it is greater than or equal to, you're going to change it to less than or equal to). The sign is going to change because the numbers being dragged over are negative. This is just a rule you have to follow. So:

x ≥ 2 is your final answer. >

Hope this helped! Feel free to ask anything else.
