Answer the Question the volume based Question. I will make uh brainliest + 50 points

Dimas [21]

To show the total capacity of container B is 132 cm³

volume = unit rate × time taken

volume = 6 cm³ × 22

volume = 132 cm³ ∴ Hence proved.

<h3 /><h3><u>Find radius</u></h3>

$\sf volume \ of \ cone = \dfrac{1}{3} \pi r^2 h$

===================

$\rightarrow \sf \dfrac{1}{3} * \dfrac{22}{7} * r^2 * 14 = 132$

<em>simplify</em>

$\rightarrow \sf \dfrac{44}{3} * r^2= 132$

<em>change sides</em>

$\rightarrow \sf r^2= \dfrac{132(3)}{44} = 9$

<em>square root both sides</em>

$\rightarrow \sf r = 3$

∴ Hence the radius of cone (Shape B is 3 cm)

<h3><u>To show the time taken</u></h3>

volume = unit rate × time taken

$\sf volume \ of \ hemi -sphere = \dfrac{2}{3} \pi r^3$

=========================

$\sf \rightarrow \dfrac{2}{3} \pi r^3 = 6 * time \ taken$

<em>Insert values</em>

$\sf \rightarrow \dfrac{2}{3} *\dfrac{22}{7} \ r^3 = 6 * time \ taken$

<em>exchange sides</em>

$\sf \rightarrow time \ taken = \dfrac{2}{3} *\dfrac{22}{7} \ r^3 *\dfrac{1}{6}$

<em>simplify following</em>

$\sf \rightarrow time \ taken = \dfrac{22}{63}r^3$

What are the zeroes of P(x) = x3 – 6x2 - x +62

Maurinko [17]

Answer:

x = 6

x = -1

x = 1

Step-by-step explanation:

Given:

Correct equation;

P(x) = x³ - 6x² - x + 6

Computation:

x³ - 6x² - x + 6

x²(x-6)-1(x-6)

(x-6)(x²-1)

we know that;

a²-b² = (a+b)(a-b)

So,

(x-6)(x²-1)

(x-6)(x+1)(x-1)

So,

zeroes are;

x = 6

x = -1

x = 1
