Answer: (C) even

Step-by-step explanation:

A function is even when f(x) = f(-x)

A function is odd when f(-x) = -f(x)

f(x) = -2x⁴ + 3x²

f(-x) = -2(-x)⁴ + 3(-x)²

= -2x⁴ + 3x²

f(x) = f(-x) so the function is even

-f(x) = -(-2x⁴ + 3x²)

= 2x⁴ - 3x²

f(-x) ≠ -f(x) so the function is not odd.

If a = b and 1/x + 1/a = 1/b then x =

seraphim [82]

1/x+1/a=1/a
minus 1/a from both sides
1/x=0
false
let's try a differnt way
1/x+1/a=1/a
times both sides by xa
a+x=x
minus x from both sides
a=0
???
1/0 is undefined
this creates problems

Add - 3/x + 7y/x . -4y/2x -3 + 7y/x - 10y/x -3 + 7y/2x

yanalaym [24]

Answer:

$-\frac{3}{x} + \frac{7y}{x} = \frac{-3+ 7y}{x}$

Step-by-step explanation:

Given

$-\frac{3}{x} , \frac{7y}{x}$

Required

Add

The statement can be interpreted as:

$-\frac{3}{x} + \frac{7y}{x}$

Take LCM

$-\frac{3}{x} + \frac{7y}{x} = \frac{-3+ 7y}{x}$

One large bubble separates into four small bubbles so that the total area of the small bubbles is equal to the area of the large

sergey [27]

Answer:

R = 10 cm

Step-by-step explanation:

The area of a spherical shape is given by :

$A=4\pi r^2$

Where

r is the radius of the sphere

ATQ,

One large bubble separates into four small bubbles so that the total area of the small bubbles is equal to the area of the large bubble.

The radius of each small bubble is 5 cm

Using the given condition,

$4\pi R^2=4\times (4\pi r^2)\\\\R^2=4r^2\\\\R=\sqrt{4r^2} \\\\R=2r\\\\R=2\times 5\\\\R=10\ cm$

So, the radius of the large bubble is equal to 10 cm.
