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

A photo 5 inches wide and 8 inches long is enlarged.
How wide is the new photo if it is (1)12 inches; (2)20 inches; (3)10 inches long?
Answers
Step-by-step explanation:
if the new photo is 12 inches long than the photo is enlarged
12/8=3/2
so the new photo is (3/2)*5 =15/2=7.5 inches wide.
Now,about the new photo 20 inches long it means that is enlarged 20/8=5/2 inches
so the new photo is wide 5*(5/2)=25/2=12,5 inches.
The photo 10 inches long is enlarged 10/8=5/4 inches.So the new photo is 5*(5/4)=25/4=6,25 inches wide.
the sum of two numbers is 30 and their difference is 20. What are the two numbers?
Answers
[tex]\huge\pink{Answer}[/tex]
Let's start by calling the two numbers we are looking for x and y.
The sum of x and y is 30. In other words, x plus y equals 30 and can be written as equation A:
x + y = 30
The difference between x and y is 20. In other words, x minus y equals 20 and can be written as equation B:
x - y = 20
Now solve equation B for x to get the revised equation B:
x - y = 20
x = 20 + y
Then substitute x in equation A from the revised equation B and then solve for y:
x + y = 30
20 + y + y = 30
20 + 2y = 30
2y = 10
y = 5
Now we know y is 5. Which means that we can substitute y for 5 in equation A and solve for x:
x + y = 30
x + 5 = 30
X = 25
Summary: The sum of two numbers is 30 and their difference is 20. What are the two numbers? Answer: 25 and 5 as proven here:
Sum: 25 + 5 = 30
Difference: 25 - 5 = 20

In the following diagram which is not drawn to scale, why can't both line AB and line AC be perpendicular to line BC?
Answers
Answer:
AC and AB both can't be perpendicular to line BC because if they were, then AB and AC would be parallel to each other and would never intersect. In this diagram, AB and AC intersect, so it it not possible.
Perpendicular lines meet at a right angle.
AB and AC cannot be perpendicular to BC because AB and AC are not parallel
From the diagram, we can see that line AB and line AC intersects at point A.
This means that both lines are not parallel
For any two lines to be perpendicular to a third line, the two lines must be parallel to each other.
So, we can conclude that:
Lines AB and AC cannot be perpendicular to line BC because both lines are not parallel.

8. A 20 degree caudal angle was used on a particular AP exam. If the patient had to be imaged with a PA projection, how would the angle change to produce the same image
Answers
Answer:
The answer is "5 or 35".
Step-by-step explanation:
It also is important to understand the difference in the AP and PA predictions, and we will talk regarding their difference, and maybe we'll take the circumstances.
It is called the PA view during the process of x-ray and as the x-ray passes from its body back to both the foreground.
Its direction was its reverse throughout the AP view. Now let's understand what critical it's really. So less the distance among object and display was also created, much clears the shadow, and according to physics concepts x-ray was its light source in this instance, but we're the target. In AP display's the rear side, which means good shadow, whereas the implications of alternative give better shadow in the PA view.
If talking around the same picture, the angle difference between both the AP and the PA visual is maximum of 15-20°.
Its situation indicates a caudal angle of 20° for the AP test. So, it must be for PA:

What is the effective annual rate for an APR of 10.60 percent compounded quarterly?
Answers
Answer:
The effective annual rate is 11.03%
Step-by-step explanation:
The effective interest rate is calculated through the formula:
[tex]r = (1 + i/n)^n - 1[/tex]
In this formula, r represents the effective interest rate, i represents the stated interest rate or APR, and n represents the number of compounding periods per year.
For a quarterly compounded interest, n=4. The APR i=10.60%=0.106
Given an APR r, the effective annual rate for a quarterly compound is:
[tex]r = (1 + 0.106/4)^4 - 1=1.0265^4-1[/tex]
[tex]r=1.11029-1=0.1103[/tex]
The effective annual rate is 11.03%
Evaluate h(x) = -2x +9

h(5)=
Answers
Answer:
[tex] f(-2) = 13 [/tex]
[tex] f(0) = 9 [/tex]
[tex] f(5) = -1 [/tex]
Step-by-step explanation:
Given:
[tex] f(x) = -2x + 9 [/tex]
Required:
Find,
h(-2); h(0), and h(5)
SOLUTION:
Plug in the value of x into [tex] f(x) = -2x + 9 [/tex] in each case as follows:
[tex] f(-2) = -2(-2) + 9 [/tex]
[tex] f(-2) = 4 + 9 [/tex]
[tex] f(-2) = 13 [/tex]
[tex] f(0) = -2(0) + 9 [/tex]
[tex] f(0) = 0 + 9 [/tex]
[tex] f(0) = 9 [/tex]
[tex] f(5) = -2(5) + 9 [/tex]
[tex] f(5) = -10 + 9 [/tex]
[tex] f(5) = -1 [/tex]
The value of h(x) when x= -2,0, and 5 is; 13, 9 and -1 respectively.
The function, h(x) given is; h(x) = -2x +9 .
As such, evaluation of h(x) when x = 2,0, and 5 is as follows;
For x = -2
h(-2) = -2(-2) +9 h(-2) = 4 +9h(-2) = 13For x = 0
h(0) = -2(0) +9 h(0) = 0 + 9h(0) = 9For x = 5
h(5) = -2(5) +9 h(5) = -10 +9h(5) = -1Read more;
