Answer:

Tyrone

Step-by-step explanation:

$Tyrone=\frac{400 yards}{1 minute} \\\\Alejandro=\frac{150 yards}{25 seconds}\\\\60 seconds = 1 minute\\\\\frac{60}{25} =2.4\\\\$

$Alejandro=\frac{150 *2.4}{25 *2.4}\\\\Alejandro=\frac{360 yards}{1 minute}\\\\\\400>360$

Apply Newton’s method to estimate the solution of x3 − x − 1 = 0 by taking x1 = 1 and finding the least n such that xn and xn +

ss7ja [257]

Solution :

Given

$f(x)=x^3-x-1, x_1=1$

$f'(x)=3x^2-1$

Let the initial approximation is $x_1 =1$

So by Newton's method, we get

$x_{n+1}=x_n-\frac{f(x_n)}{f'(x_n)},n=1,2,...$

$x_2=x_1-\frac{f(x_1)}{f'(x_1)}=1-\frac{1^3-1-1}{3(1)^2-1}=1.5$

$x_3=1.5-\frac{(1.5)^3-1.5-1}{3(1.5)^2-1}=1.34782608$

$x_4=1.34782608-\frac{(1.34782608)^3-1.34782608-1}{3(1.34782608)^2-1}=1.32520039$

$x_5=1.32520039-\frac{(1.32520039)^3-1.32520039-1}{3(1.32520039)^2-1}=1.32471817$

$x_6=1.32471817-\frac{(1.32471817)^3-1.32471817-1}{3(1.32471817)^2-1}=1.32471795$

$x_5 \approx x_6$ are identical up to eight decimal places.

The approximate real root is x ≈ 1.32471795

∴ x = 1.32471795

It would be B because you would take amelias age and take two away since todd is five years younger to get the a-5.
hope this helps :)

Which answer is a solution of the equation?

Nuetrik [128]

2x + y = 5

Put the coordinates of the points to the equation and check it:

A. 5 - not make sense

B. (1, 2) - x = 1, y = 2

2(1) + 2 = 2 + 2 = 4 ≠ 5 NOT

C. (2, -1) - x = 2, y = -1

2(2) + (-1) = 4 - 1 = 2 ≠ 5 NOT

D. (3, -1) - x = 3, y = -1

2(3) + (-1) = 6 - 1 = 5 YES

<h3>Answer: D. (3, -1).</h3>
