1) 25% of 176 = 44
2) 90% of 20 = 18
3) 24 is 80% of 30

1. 25% if 1/4, so we want to find 1/4 of 176. Best way to get the result is just divide 176 by 4, so 176:4=44 - its the answer.

2. To get the answer we can use proportion
100% -----------20
90% ---------- x
crossmultiply now
100x=90*20
100x=1800     /:100        divide both sides by 100
x=18 - its the answer

3. Similar problem
24 ---------- x
30 ---------- 100%
crossmultiply now
24*100%=30x 
2400%=30x     /:30 divide both sides by 30
2400%:30=x
80%=x - its the answer

Calculate two iterations of Newton's Method to approximate a zero of the function using the given initial guess. (Round your ans
VikaD [51]

Answer:

The two iterations of f(x) = 1.5598

Step-by-step explanation:

If we apply  Newton's iterations method, we get a new guess of a zero of a function, f(x), xₙ₊₁, using a previous guess of, xₙ.

xₙ₊₁ = xₙ - f(xₙ) / f'(xₙ)

Given;

f(xₙ) = cos x, then  f'(xₙ) = - sin x

cos x / - sin x = -cot x

substitute in "-cot x" into the equation

xₙ₊₁ = xₙ - (- cot x)

xₙ₊₁ = xₙ + cot x

x₁ = 0.7

first iteration

x₂ = 0.7 + cot (0.7)

x₂ =  0.7 + 1.18724

x₂ = 1.88724

 

second iteration

x₃ = 1.88724 + cot (1.88724)

x₃ = 1.88724 - 0.32744

x₃ = 1.5598

To four decimal places = 1.5598
