use gaussian quadrature to evaluate the following integrand. ∫ sin () 1 , 4 −4 use node n=4

Answers

Answer 1

Therefore, using Gaussian Quadrature with 4 nodes, the value of the integral ∫ sin(x)dx from -4 to 1 is approximately 0.003635.

To evaluate the given integral using Gaussian Quadrature with 4 nodes, we need to follow these steps:

Step 1: Convert the integral to the standard form: ∫ f(x)dx ≈ ∑wi f(xi)

where wi are the weights and xi are the nodes.

Step 2: Determine the weights and nodes using the Gaussian Quadrature formula for n = 4:

wi = ci/[(1-xi^2)*[P3(xi)]^2]

where ci are the normalization constants and P3(xi) is the Legendre polynomial of degree 3 evaluated at xi.

Using a table of values for the Legendre polynomials, we can find the nodes and weights for n = 4:

c1 = c2 = c3 = c4 = 1

x1 = -0.861136, w1 = 0.347855

x2 = -0.339981, w2 = 0.652145

x3 = 0.339981, w3 = 0.652145

x4 = 0.861136, w4 = 0.347855

Step 3: Evaluate the integral using the weights and nodes:

∫ sin(x)dx from -4 to 1 ≈ w1f(x1) + w2f(x2) + w3f(x3) + w4f(x4)

≈ 0.347855sin(-0.861136) + 0.652145sin(-0.339981) + 0.652145sin(0.339981) + 0.347855sin(0.861136)

≈ 0.003635

A cone has a volume of 47.1 cm³ and a radius of 3 cm what is its height?

Answers

Radius of cone ( r ) = 3 cm,

Curved surface area of a cone= 47.1 cm²

Curved surface area of a cone= πrl

47.1 = πrl

47.1 = 3.14 × 3 × l

l = 47.1 / (3.14 × 3)

l = 15.7 / 3.14= 1570/314= 5 cm

slant height (l) = 5 cm

Height of a cone (h) = √(l²) - (r²)

h = √ 5² -3²

h = √ 25 - 9 = √ 16 = 4 cm

h = 4 cm

Volume of cone= ⅓(πr²h)

= ⅓(3.14 × 3 × 3 × 4)

= 3.14 × 12= 37.68 cm³

Hence, the volume of a cone is 37.68 cm³.

Probability helps us to know the chances of an event occurring. The likelihood that best describes the probability of this event is Likely.

What is Probability?

Probability helps us to know the chances of an event occurring.

[tex]\rm Probability=\dfrac{Desired\ Outcomes}{Total\ Number\ of\ outcomes\ possible}[/tex]

Given the probability of landing on blue when spinning a spinner is 4/5, therefore, there are 80% chances that the spinner will land on blue.

Hence, the likelihood that best describes the probability of this event is Likely.

Write the linear equation in slope-intercept form given the following:
(-3, 7) and (6, -8)

Answers

Answer:

y = - [tex]\frac{5}{3}[/tex] x + 2

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (- 3, 7) and (x₂, y₂ ) = (6, - 8)

m = [tex]\frac{-8-7}{6+3}[/tex] = [tex]\frac{-15}{9}[/tex] = - [tex]\frac{5}{3}[/tex] , then

y = - [tex]\frac{5}{3}[/tex] x + c ← is the partial equation

To find c substitute either of the 2 points into the partial equation

Using (6, - 8) , then

- 8 = - 10 + c ⇒ c = - 8 + 10 = 2

y = - [tex]\frac{5}{3}[/tex] x + 2 ← equation of line
