Answer:
V = 20.2969 mm^3 @ t = 10
r = 1.692 mm @ t = 10
Step-by-step explanation:
The solution to the first order ordinary differential equation:

Using Euler's method

Where initial droplet volume is:

Hence, the iterative solution will be as next:
- i = 1, ti = 0, Vi = 65.45

- i = 2, ti = 0.5, Vi = 63.88

- i = 3, ti = 1, Vi = 62.33

We compute the next iterations in MATLAB (see attachment)
Volume @ t = 10 is = 20.2969
The droplet radius at t=10 mins

The average change of droplet radius with time is:
Δr/Δt = 
The value of the evaporation rate is close the value of k = 0.08 mm/min
Hence, the results are accurate and consistent!
Answer:
x = 13°
Step-by-step explanation:
5x+15°=7x-11°
5x-7x = -11°-15°
-2x = -26° divide both sides by -2
x = 13°
5x+15° = 5×13°+15° = 80°
7x-11° = 7×13° -11°. = 80°
Answer:
Step-by-step explanation:one of all
Hehehehe
Hahaha
Eat eat eat ugly ah glad to help
I did the quiz
-4(-5) = -4*-5 = 20
6 - (-4) = 10
Quotient = 20 /10 = 2 answer
