4] Which perfect square root is close to
?
Well we know that 7 times 7 is 49, and 6 times 6 is 36, so our answer will be between
and 
The closer root is
, so we can approximate that the square root of 39 is around <u><em>6.2</em></u>.
5] We can do a similar step-by-step here.
4 times 4 is 16, and 5 times 5 is 20.
This gives us
and 
Well, they are both equal distance from
(2), so we can do this:
We know it'll be between 4 and 5 (the number plot in the answer lets us know that too)
4 times 4 is 16
4.1 times 4.1 is around 16.8
4.2 times 4.2 is about 17.64
4.3 times 4.3 is 18.49
Now that we have an 18, we can stop going and see which one is closer.
18 - 18.49 = -0.49
18 - 17.64 = 0.36
4.2 times 4.2 is closer, so we can approzimate that
is around 4.2

Note] Hope this helps! Upon using a calculator I can confirm these answers are correct :D
1 quart = 0.95 litres
7 quarts = 6.65 litres
To get from 1 quart to 7 quarts you times by 7, and if one quart is 0.95 litres, to find out what 7 quarts is equal to in litres you have to times 0.95 by 7.
Answer:
Step-by-step explanation:
symmetry with respect to y-axis for y=f(x) means f(-x)=f(x)
in this case, y = f(x) = x / (x^2+4)
f(-x) = -x / ((-x)^2+4) = -x / (x^2+4) = -f(x)
so it is not symmetric to y-axis
symmetry with respect to x-axis for x=g(y) means g(-y)=g(y)
in this case, y = x / (x^2+4)
y*(x^2+4) = x
y*x^2 + 4y - x = 0
substitute -y into g(y)
(-y)*x^2 +4(-y) - x = 0
-y*x^2 - 4y - x = 0
y*x^2 + 4y + x = 0
so g(-y) is not equal to g(y)
so it is not symmetric to x-axis
Answer: 2(x + 5) less than 3x
Step-by-step explanation: 2 = twice the... x + 5 = the sum of a number and 5 (number = x) 3x = three times the number
Ouuu ion I gotta do the math on it cause I’m not on math rn
