Answer:

B. 64

Step-by-step explanation:

Note that $a^{-n}$ = $\frac{1}{a^{n} }$ . Therefore

$(2w^{-2} )^{3} * (8w^{6} )$ = $8w^{-6}$ * $8w^{6}$ = 8 * $\frac{1}{w^{6} }$ * 8 * $w^{6}$ = 8 * 8 * $\frac{w^{6} }{w^{6} }$ = 8 * 8 * 1 8 * 8 = 64

Bess [88]

Answer:

the smallest number of equally sized pieces is 20

Step-by-step explanation:

The computation of the smallest number of equally sized pieces is as follows:

Given that

The sum of 1 by 5 and 3/4

Now

if we sum it

= 1 ÷ 5 + 3 ÷ 4

= 4 + 15 ÷ 20

= 19 ÷ 20

Now as if we do the lcm so the denominator sum be 20

Therefore the smallest number of equally sized pieces is 20

Find the maximum/minimum value of the function y = x2 - (5/3)x + 31/36.

AysviL [449]

Answer:

Step-by-step explanation:

Given a parabola in standard form, y = ax² + bx + c ( a ≠ 0 ), then

minimum/ maximum value is the y- coordinate of the vertex.

The x- coordinate of the vertex is

$x_{vertex}$ = - $\frac{b}{2a}$

y = x² - $\frac{5}{3}$ x + $\frac{31}{36}$ ← is in standard form

with a = 1 and b = - $\frac{5}{3}$ , thus

$\frac{x}{vertex}$ = - $\frac{-\frac{5}{3} }{2}$ = $\frac{5}{6}$

Substitute this value into y

y = ( $\frac{5}{6}$ )² - $\frac{5}{3}$ ( $\frac{5}{6}$ ) + $\frac{31}{36}$

= $\frac{25}{36}$ - $\frac{25}{18}$ + $\frac{31}{36}$ = $\frac{1}{6}$

Since a > 1 then the vertex is a minimum, thus

minimum value = $\frac{1}{6}$ → A
