Answer:

y = 10√16) = 40

Step-by-step explanation:

This says, "y is proportional to the square root of x." We are told that y = 60 when x = 36. Find the formula for this function. Then, determine what value y will take on when x = 16.

y = k√x becomes 60 = k√36, or 60 = 6k. Then k must be 10, and the formula is y = 10√x.

If x = 16, y = 10√16) = 40

What is the factored form of _________?

enyata [817]

Answer:

Step-by-step explanation:

The expression given is a difference of cubes and factors as

a³ - b³ = (a - b)(a² + ab + b²)

8 $x^{24}$ = (2 $x^{8}$ )³ ⇒ a = 2 $x^{8}$

27 $y^{6}$ = (3y²)³ ⇒ b = 3y²

Hence 2 factors are

(2 $x^{8}$ - 3y²) and

((2 $x^{8}$ )² + (2 $x^{8}$ × 3y²) + (3y²)²)

= (4 $x^{16}$ + 6 $x^{8}$ y² + 9 $y^{4}$ )

Hence the factored form of the expression is C
