Use the number line to answer the question. A number line going from negative 5 to positive 5. Point A is negative 1, point B is

0, point C is 1, and point D is 4.5. Which statement about graphing rational numbers is true? The graphs of all rational numbers will be to the right of point B. The graphs of all rational numbers will be to the left of point B. Point D does not represent a rational number. All of the points on the graph could represent rational numbers.

Answer:

The last one

Step-by-step explanation:

all points on the graph are rational numbers.

-1, 0, 1, and 4.5 are all rational numbers

rational numbers consist of;

natural numbers "1, 2, 3, 4, etc"

whole numbers "0, 1, 2, 3, etc"

integers "-3, -2, -1, 0, 1, 2, 3, etc"

And decimals "-1.5, -1, -0.5, 0, 0.5, 1, 1.5 etc"

*and fractions "1/2 3/5 6/17"

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

In 1983, a can of house paint cost $16.35. In 2000, a can of house paint cost $28.94, and in 2005, a can of house paint cost $32

The Consumer Price Index is calculated through the equation,
                             CPI = (current period price/base period price) x 100
The base period is 1983. Solving the CPIs for 2000 and 2005
         (2000) 
                             CPI = ($28.94/$16.35) x 100 = 177
        (2005)           
                             CPI = ($32.54/$16.35) x 100 = 199
The difference between the CPIs of 2005 and 2000 is 199 - 177 = 22.
