A rational number is a number that can be written in form a/b where a and b are integers and b is not eual to 0

simplify eacy
$\sqrt{8}=2\sqrt{2}$
$\sqrt{16}=4$
we get

$\frac{2\sqrt{2}}{3}+4$
$\sqrt{2}$ is irrational
since we can't write $\sqrt{2}$ as a rational number, the entire phrase is irrational

anwer is irrational

F(x) = x^2, g(x) = 2/3 x^2 comparison

daser333 [38]

Answer:

g(x) is a vertical compression of f(x)

Step-by-step explanation:

Equation of graph 1 : $f(x)=x^2$

Equation of graph 2 : $g(x)=\frac{2}{3}x^2$

f(x)→a f(x)

Its is case of vertical stretch or compression

Vertical stretch if |a|>1

Vertical compression if 0<|a|<1

f(x)→a f(x)

So, $x^2$ → $\frac{2}{3}x^2$

So, $a= \frac{2}{3}=0.67$

So,0<|a|<1

So,It is a case of vertical compression

So, g(x) is a vertical compression of f(x)

9 is what percent of 20?

liberstina [14]

So percent means parts out of 100 so
1%=1/100

so 9/20=x/100
a hack withought using legit math is
20 times 5=100 so
9/20 times 5/5=x/100
9 times 5=45
20 times 5=100
45/100
45% is the answer

3. Every time Deucalion threw one stone over his shoulder, eight people sprang

kvv77 [185]

Answer:

1156

Step-by-step explanation:

When Deucalion threw one stone over his shoulder, 8 people appear. So, for every stone, we have 8 new people.

Therefore, if Deucalion threw 68 stones, the number of people that would appear is

$n_1=68\cdot 8 =544$
