Which number is the largest? <br> 1.2 × 104, 4.5 × 10−3, 3.8 × 103, 7.5 × 103

Artemon [7]

Answer:

1.2 x 10^4 = 12,000

4.5 x 10^-3 = 4.5 x 1/(10^3) = 4.5/1000 = 0.0045

3.8 x 10^3 = 3,000

7.5 x 10^3 = 7,000

largest is 1.2 x 10^4

Determine whether the function f(x) -1 / x^2 + x^4 is even odd or neither

kirill [66]

If f(-x) = f(x) then the function is even.

If f(-x) = -f(x) then the function is odd.

We have: $f(x)=\dfrac{-1}{x^2+x^4}$

calculate f(-x):

$f(-x)=\dfrac{-1}{(-x)^2+(-x)^4}=\dfrac{-1}{(-1x)^2+(-1x)^4}\\\\=\dfrac{-1}{(-1)^2x^2+(-1)^4x^4}=\dfrac{-1}{1x^2+1x^4}=\dfrac{-1}{x^2+x^4}=f(x)$

f(-x) = f(x), therefore your answer: The function f(x) is even.

If we have: $f(x)=\dfrac{-1}{x^2}+x^4$

$f(-x)=\dfrac{-1}{(-x)^2}+(-x)^4=\dfrac{-1}{x^2}+x^4$

f(-x) = f(x)

f(x) is even

Pls answer 10 points I will mark brainliest

Degger [83]

Answer:

500 cm³

Step-by-step explanation:

Using the given values in the given formula, we find the volume to be ...

$V=\dfrac{4}{3}\pi r^3\\\\V=\dfrac{4}{3}(3)(5\text{ cm})^3 = 4(125\text{ cm}^3) = \boxed{500\text{ cm}^3}$

The volume of the sphere is about 500 cubic centimeters.

_____

<em>Additional comment</em>

The actual value of pi would add about 4.72% to this figure, bringing the estimate to about 523.6 cm³.
