Expand the integrand:

$(2x - 3) (4x^2 + 1) = 8x^3 - 12x^2 + 2x - 3$

Then integrate using the power rule:

$\displaystyle \int (8x^3-12x^2+2x-3) \, dx = 2x^4 - 4x^3 + x^2 - 3x + C$

By the fundamental theorem of calculus, the definite integral has a value of

$\displaystyle \int_0^2 (2x-3)(4x^2+1) \, dx = \left(2x^4 - 4x^3 + x^2 - 3x\right)\bigg|_{x=2} - \left(2x^4 - 4x^3 + x^2 - 3x\right)\bigg|_{x=0}$

$\displaystyle \int_0^2 (2x-3)(4x^2+1) \, dx = 32 - 32 + 4 - 6 = \boxed{-2}$

A potato chip company produces a large number of potato chip bags each day and wants to investigate whether a new packaging mach

alexandr1967 [171]

Answer:

The conditions for the approximation have been met

Step-by-step explanation:

Random samples on both cases and

p∧o proportion of bags packaged on the old machine that are damaged

p∧n sample proportion of bags packaged on the new machine that are damaged

p∧c = ( p∧o + p∧n ) / (nO + nN )

p∧o = 15 % p∧o = 0,15 nO = 150

p∧o * nO = 0,15 *150 p∧o * nO = 22,5

p∧n = 8 % p∧n = 0,08 nN = 200

p∧n*nN = 0,08 * 200 p∧n*nN = 16

Both p∧n*nN and p∧o * nO are bigger than 5

Therefore both samples are big enough for the approximation of the binomial distribution to normal distribution

It took a skydiver 15 seconds to drop 450 feet. What is the

Citrus2011 [14]

Answer:

30feet/second

Step-by-step explanation:

The rate in feet per seconds of the diver will be the speed of the diver.

Speed is the rate of change in distance of a body.

Speed = Distance/Time

Given distance or height of drop = 450feet

Time = 15seconds

Rate of change in distance = 450/15

Rate of change in distance = 30feet/second
