5 0

First off,we can find out how much an oz cost for each package:

Package of brown rice:
0.79÷16
=$0.049375
≈$0.049

Package of white rice:
3.99÷32
=$0.1246875
≈$0.125

Price of brown rice:$0.049 < price of white rice:$0.125

Therefore,brown rice is a better deal as it is cheaper.

Hope it helps!

Answer: It has two distinct real zeros.

Step-by-step explanation:

The formula that is used to calculate the discriminant of a Quadratic function is the one shown below:

$D=b^2-4ac$

In this case you have the following Quadractic function provided in the exercise:

$f(x)=6x^2 +10x-1$

Let's make it equal to 0:

$0=6x^2 +10x-1$

You can identify that:

$a=6\\\\b=10$

Knowing these values, you can substitute them into the formula and then evaluate:

$D=10^2-4(6)(-1)\\\\D=124$

Therefore, since:

$D>0$

You can determine that the it has two distinct real roots.

Evaluate the integral:<br> dx / e^(pie*x) from 2 (upper bound) to 0.

kenny6666 [7]

Substitution:
u = - π x
d u = - π d x
d x = - d u / π
----------------------
$-1/ \pi \int\limits^2_0 {e ^{u} } \, du =- \frac{e ^{- \pi x} }{ \pi } = \\ -1/ \pi (e ^{-2 \pi } -1) = \\ = \frac{1}{ \pi } - \frac{1}{ \pi e ^{2 \pi } }$
