Find the cube root of 10 upto 5 signaficant figures by newton raphson method
AnnZ [12381]

Answer: The cube root of 10 is 2.1544, using an initial value of -0.003723.

Step-by-step explanation: The Newton-Raphson method is utilized for root finding, and its formula is NR: X=Xo-(f(x)/f'(x)). Before applying this formula, the derivative of the equation must be determined. Given that X =10, this method was implemented to identify the best root to ascertain the cube root of 10 to 5 significant figures. Utilizing software like Excel for quicker iteration calculations is advisable. The found root in this instance was -0.003723.

The table represents the equation y = 2 – 4x. A 2-column table with 5 rows. The first column is labeled x with entries negative
tester [12383]

The missing value associated with x=-1 is y=6

Explanation:

The provided equation for the table is y=2-4x

This table consists of 2 columns and 5 rows.

<pconsequently it="" states="">

x       y

-2      10

-1       ---

0        2

1        -2

2       -6

To find the value for y when x=-1

The value of y can be ascertained by substituting x=-1 into the equation y=2-4x

<pthus we="" determine="">

y=2-4(-1)

<pmultiplying the="" term="" within="" brackets="" yields="">

y=2+4

<psumming the="" terms="" we="" find="">

y=6

<pso the="">value of y when x=-1 is 6.

Hence, the value for x=-1 is y=6
