The conversion of ammonium cyanide to urea is a second-order reaction. This means that the concentration C of ammonium cyanide a

t time t is given by 1/C = kt + 1/C0, where C0 is the initial concentration and k is the rate constant. Assume the initial concentration is known to be 0.1 mol/L exactly. Assume that time can be measured with negligible uncertainty.
a. After 45 minutes, the concentration of ammonium cyanide is measured to be 0.0811 ? 0.0005 mol/L. Estimate the rat? constant k, and find the uncertainty in the estimate.

b. Use the result in part (a) to estimate the time when the concentration of ammonium cyanide will be 0.0750 mol/L, and find the uncertainty in this estimate.

The Supplemental Security Income (SSI) program, administered by the Social Security Administration (SSA), is the income source of last resort for thelow-income aged, blind, and disabled. As the nation's largest income-assistance program, it paid $38 billion in benefits in calendar year 2006 to roughly 7 million recipients per month. BecauseSSI is means tested, administering the program often requires month-to-month, recipient-by-recipient benefit recomputations. An increase in a recipient's income usually triggers a benefit recomputation. Or, an increase in the recipient's financial assets, which may render the recipient ineligible, would also prompt a recomputation. With this crush of ongoing recomputations, it is of little wonder that administrative simplification is a time-honored mantra for program administrators.

Consider the function. What is the y-intercept of f–1(x)? –16 –12
Mekhanik [1.2K]
<h2>Explanation:</h2><h2></h2>

Hello! Remember you have to write clear questions in order to get good and exact answers. Here, I'll assume the function as:

f(x)=x^2+2x-16

The y-intercept of a function is the point at which the graph of the function touches the y-axis. This occurs when we set x=0. In other words, we define the y-intercept (let's call it b as:

b=f(0)

Setting x=0 in our function we have:

b=f(0)=(0)^2+2(0)-16 \\ \\ \boxed{b=f(0)=-16}

So <em>in this context the y-intercept is -16</em>

What’s -2y+16=10 plz solve 2 step equation
konstantin123 [22]

Answer:

y=3

Step-by-step explanation:

To solve this 2 step equation, we need to get y alone. Lets write out the equation

-2y+16=10

Subtract 16 from both sides

-2y-16+16=10-16

Subtract

-2y=-6

divide both sides by -2

-2y/-2=-6/-2

divide

y=3
