WILL MARK BRAINLIEST FOR BEST ANSWER
MatroZZZ [7]

Answer:

5−x²+2xy−y²

Step-by-step explanation:

5 - (x-y)²

Rewrite  

(x−y)² as (x−y)(x−y) so

5−((x−y)(x−y))

Expand (x−y)(x−y) using the FOIL Method

Apply the distributive property.

5−(x(x−y)−y(x−y))

Apply the distributive property

5−(x⋅x+x(−y)−y(x−y))

Apply the distributive property

5−(x⋅x+x(−y)−yx−y(−y))

Simplify and combine like terms  

Simplify each term

5−(x²−xy−yx+y²)

Subtract yx from −xy  

5−(x²−2xy+y²)

Apply the distributive property

5−x²−(−2xy)−y²

Multiply  −2 by −1

5−x²+2xy−y²

The volume of a conical pile of sand is increasing at a rate of 300πcm3/sec
lesya [120]
So using the formula for the volume of a cone:
r^2pi x h/3

The height is always 4 times the radius, so:
h=4r

Now putting the values into the original formula:

r^2pi x 4r/3

Now to see how much the radius increases per second:

r^2pi x 4r/3=300pi

r^2 x 4r/3=300

r^2 x 4r=900

r^2 x r=225

r^3=225

The radius increases by the cubic square root of 225 cm per second.

f(s)= 225^1/3 cm

On what interval is the function h(f)=|x+2|-2 increasing ?
VLD [36.1K]

Answer:

The increasing interval is S=(-2,\infty)

Step-by-step explanation:

This absolute function has a vertex in x=-2. Now, from this point, the function has a positive slope (increasing), which means for values of x equals to -1,0,1,2,3,...,n.

Therefore the interval will

S=(-2,\infty)
