PLEASE HELP!

Use the given recursion and starting value of x_0 = 2.4 to find x_1 :

x_1 = \dfrac{x_0 + \frac6{x_0}}2 = \dfrac{2.4 + \frac{6}{2.4}}2 = 2.45

Do the same for x_2 and x_3 :

x_2 = \dfrac{x_1 + \frac6{x_1}}2 = \dfrac{2.45 + \frac6{2.45}}2 \approx 2.44949

x_3 = \dfrac{x_2+\frac6{x_2}}2 \approx \dfrac{2.44949 + \frac6{2.44949}}2 \approx \boxed{2.44949}

(That's not a mistake. This just tells you that the 2nd and 3rd iterates are very close together and have at least the same first 5 digits after the decimal.)

ra1l [238]

Answer:

$ 154

Step-by-step explanation

Let the value of suitcase=x

x × 4.5% = 6.93 (converted the question into equation)

x × \frac{4.5}{100} = 6.93 (converted the percentage into fraction)

x = 6.93 x \frac{100}{4.5} (took reciprocal of 4.5/100 after moving it to the other side of the equation)

x = \frac{693}{4.5} (multiplied the values)

x = 154 $ (simplified the fraction)

make it the brainliest and get 20 years of luck : )
