Answer:

1437.33

Step-by-step explanation:

first,

r = d/2

r = 14/2

r = 7

now,

4/3πr³

4/3 × 22/7 (7)³ [ π = 22/7]

88/21 × 343

30184/21

1437.33

What is the absolute value of –6? Use the number line to help answer the question. A number line going from negative 7 to positi

drek231 [11]

<h3>Answer: 6</h3>

Mark the locations -6 and 0 on the number line. Note that going from -6 to 0, or vice versa, will take exactly 6 steps. Put another way, the distance between 0 and -6 is 6 units. Absolute value represents distance, so it is never negative.

We say $|-6| = 6$

Effectively, all we're doing is removing the negative sign.

How do you find the zeros of an equation

lubasha [3.4K]

Answer:

Step-by-step explanation:

In general, given the function, f(x), its zeros can be found by setting the function to zero. The values of x that represent the set equation are the zeroes of the function. To find the zeros of a function, find the values of x where f(x) = 0.

Help mi out plz..... solve using matrix method

HACTEHA [7]

Answer:

x = $\frac{22}{7}$

y = $\frac{3}7}$

Step-by-step explanation:

$2x-3y=5\\5x=4y=14\\\\\left[\begin{array}{cc}2&-3\\5&-4\\\end{array}\right] \left[\begin{array}{c}x\\y\\\end{array}\right] =\left[\begin{array}{c}5\\14\\\end{array}\right]$

Let A = $\\\left[\begin{array}{cc}2&-3\\5&-4\\\end{array}\right]$

The inverse of A multiplied by A = the identity matrix $\left[\begin{array}{cc}1&0\\0&1\\\end{array}\right]$

Inverse of A = $\frac{1}{detA}$ $\left[\begin{array}{ccc}-4&3\\-5&2\\\end{array}\right]$

detA = ad - bc = $-8 - - 15 = 7$

Inverse of A = $\left[\begin{array}{cc}\frac{-4}{7} &\frac{3}{7} \\\frac{-5}{7} &\frac{2}{7}\\\end{array}\right]$

$\left[\begin{array}{ccc}x\\y\\\end{array}\right] = \left[\begin{array}{cc}\frac{-4}{7} &\frac{3}{7} \\\frac{-5}{7} &\frac{2}{7}\\\end{array}\right] \left[\begin{array}{ccc}5\\14\\\end{array}\right] = \left[\begin{array}{ccc}\frac{22}{7} \\\frac{3}{7} \\\end{array}\right]$
