Answer:

c = 9/16

Step-by-step explanation:

<h3>step1</h3>

(a-b)²

a² - 2ab + b²

here a = x

        b = ?

   

so

x² - (2)(x)(?) + ?²

Now we can see that -(2x)? = -3x/2

                                    -2x? = -3x/2

cancel -x on both sides

2? = 3/2

? =  3/2 * (2)

? =  3/4

so b = 3/4

<h3>step2</h3>

(x² - 3x + 9/16) = (x-3/4)²

so from the expression we can see that C = 9/16

Value discounting refers to the fact that the percieved value of the reinforcer is less the longer you have to wait for it. See
vekshin1

Answer:

there is an economic principle that states that 1 dollar today is worth more than 1 dollar in the future, since an invested dollar could earn interests and gain value.

For example, we can assume a 6% interest rate (0.5% monthly interest rate), and using the present value formula we can determine the present value of $100:

  • given to us in 30 days = $100 / (1 + 0.5%)¹ = $99.50
  • given to us in 150 days = $100 / (1 + 0.5%)⁵ = $97.54
  • given to us in 300 days = $100 / (1 + 0.5%)¹⁰ = $95.13

In order to calculate the value of $100 given to us tomorrow, we would need to determine a daily interest rate = 6% / 360 = 0.00017

  • $100 given to us tomorrow = $100 / (1 + 0.00017)¹ = $99.98

since the amount of money is not that large and the interest rate is rather low, the difference in value is not that large. But imagine if you used a 24% interest rate instead of 6% (monthly interest rate = 2%)

  • $100 given to us in 30 days = $100 / (1 + 2%)¹ = $98.04
  • $100 given to us in 150 days = $100 / (1 + 2%)⁵ = $90.57
  • $100 given to us in 300 days = $100 / (1 + 2%)¹⁰ = $82.03

as the interest rate increases, the present value decreases.

Hi guys, can anyone help me with this triple integral? Many thanks:)
Crank

Another triple integral.  We're integrating over the interior of the sphere

x^2+y^2+z^2=2^2

Let's do the outer integral over z.   z stays within the sphere so it goes from -2 to 2.

For the middle integral we have

y^2=4-x^2-z^2

x is the inner integral so at this point we conservatively say its zero.  That means y goes from -\sqrt{4-z^2} and +\sqrt{4-z^2}

Similarly the inner integral x goes between \pm-\sqrt{4-y^2-z^2}

So we rewrite the integral

\displaystyle \int_{-2}^{2} \int_{-\sqrt{4-z^2}}^{\sqrt{4-z^2}} \int_{-\sqrt{4-y^2-z^2}}^{\sqrt{4-y^2-z^2}} (x^2+xy+y^2)dx \; dy \; dz

Let's work on the inner one,

\displaystyle\int_{-\sqrt{4-y^2-z^2}}^{\sqrt{4-y^2-z^2}} (x^2+xy+y^2)dz

There's no z in the integrand, so we treat it as a constant.

=(x^2+xy+y^2)z \bigg|_{z=-\sqrt{4-y^2-z^2}}^{z=\sqrt{4-y^2-z^2}}

So the middle integral is

\displaystyle\int_{-\sqrt{4-z^2}}^{\sqrt{4-z^2}}2(x^2+xy+y^2)\sqrt{4-y^2-z^2} \ dy  

I gotta go so I'll stop here, sorry.
