Answer:
$9.52
Step-by-step explanation:
4.25 divided by 100 gets you 0.0425 then multiply that number by 224
Answer:
Step-by-step explanation:
midline: y = -2 (take the average of the min and max)
amplitude = 1.5 (distance from min or max to midline. Always a positive number)
period = 4pi
Current density of solution a/m2 is given below
Step-by-step explanation:
Current density is the measure of current generated per unit surface area of electrode.
Eg: In microbial fuel cell/fuel cells, if you are using electrode with size of 5cm x 2cm and current produced is 200mA, then current density will be,
CD= Current/(projected area of electrode)
area of rectangle= LxB= 5cm x 2cm =10cm2
CD= 200mA/10cm2
CD= 20mA/cm2
Your Current will be 200mA.
Current density will be 20mA/cm2.
Answer/Step-by-step explanation:
3. By substitution method, let's substitute
for y in the first equation.
Thus,
Solve for x

Add 4 to both sides




Multiply both sides by 3


Divide both sides by 5

Now, substitute 3 for x in the equation.




The solution of the equation is x = 3, y = -2
4. Solving by elimination, let's try to eliminate the x-variable by adding both equation together.


=> 
Divide both sides by -3 to solve for y


Substitute -5 for y in the first equation to find x


Subtract 10 from both sides


Divide both sides by 3


The solution is 
Find slope first
(2-1)/(8-4) = 1/4
Format: y = mx + b
y = 1/4x + b
Plug in one point
1 = 1/4(4) + b, b = 0
Solution y = 1/4x
