What is the square root of -9

Mathematics

Maksim231197 [3]3 years ago

You actually can’t get the exact square root of a negative number, it is not 3 as 3 squared is 9 not negative 9. It is not possible to square a number to get a negative answer, that’s where all the “i” stuff comes in with irrational numbers.

There are 20 small tropical fish swimming in a 55-gallon aquarium. What is the population density?
umka21 [38]

Answer:

The population density is 0.364 fish per gallon.

Step-by-step explanation:

The population density can be defined as the number of individuals (in this case, small tropical fish) per unit of area or volume. In this case, the volume of the aquarium (55 gallon).

The density can be calculated then as:

d=\dfrac{P}{V}=\dfrac{20\;\text{fish}}{55\;\text{gal}}\approx0.364\dfrac{\text{fish}}{\text{gal}}

The population density is 0.364 fish per gallon.

If f(x) = 2x^2 + 1 and g(x) = x^2 - 7, find (f+g)(x)
jarptica [38.1K]
(f + g)(x) means f(x) + g(x)

So, you just input the function of f(x) and g(x) altogether, then simplify it.
(f + g)(x) 
= f(x) + g(x)
= 2x² + 1 + x² - 7
= 2x² + x² + 1 - 7
= 3x² - 6

The answer is b

210 is equal to the total of p and 111
Aleks [24]

Answer:

p + 111 = 210

p = 99

Step-by-step explanation:

Break the question down into parts.

<u>Convert each part into algebraic form</u> (numbers or symbols).

210                                =>   210

is equal to                    =>   =

the total of p and 111    =>   p + 111

Put the equation together:

210 = p + 111

Usually, the variable is on the left side:

p + 111 = 210

<u>To solve the equation is to isolate "p"</u>. This means to keep "p" on the left, and move everything else to the right side. When moving something, do the <u>reverse operation</u> to both sides of the equation.

p + 111 = 210            "111" should be on the left. It's opposite is -111.

p + 111 - 111 = 210 - 111                Simplify. "111" cancels out on the left.

p = 99                     Solved for "p"
