The equation x^3-5x=59 has a solution between 4 and 5. Use a trial and improvement method to find this solution. Give your answe

vodomira [7]

Answer:

The answer is "4.3".

Step-by-step explanation:

Given:

$\to x^3 - 5x - 59 = 0$

When $x = 4.1:$

$\to f(4.1) = (4.1)^3 - 5(4.1) - 59 = -10.579$

When $x= 4.2:$

$f(4.2) = 4.2^3 - 5(4.2) - 59 = -5.912$

When $x = 4.3:$

$\to f(4.3) = -0.993$ (closer to 0)

$\to f(4.4) = 4.184$

It changes the sign so, the root lies in 4.3 and 4.4.

When $x = 4.35:$

$\to f(4.35) = 1.563$

When the root is closer to 4.3 than 4.4 So, 1.563 is closer to zero than 4.184.

When $x = 4.32:$

$\to f(4.32) = 0.0216$ close to zero.

So the answer is 4.3 to 1 decimal place.

Find the x and y intercepts of the graph of the equation 1. 3x-4y=24 2. -6x+3y=12

deff fn [24]

Answer:

Step-by-step explanation:

Recall the intercept form of the line

x/a + y/b = 1

has intercepts at (1,0) and (0,b)

#1. Divide by 24 to get x/8 + y/-6 = 1

The intercepts are at (8,0) and (0,-6)

#2 Divide by 12

x/-2 + y/4 = 1
