Answer:
The answer is
Step-by-step explanation:
Assuming the snowball is a perfect sphere, then if A denotes the surface area and D the diameter then:
Differentiating wrt r we have:
We are told that and we want to find
By the chain rule we have:
∴
∴
When D=10 then
The sign (-) shows that the D is decreasing.
Use the following abbreviations:
y = year,
d = day,
h = hour,
min = minute,
s = second,
ms = millisecond.
Then
Therefore, the correct calculation is
1000 * 60 * 60 * 24 * 365
Answer: 1000 * 60 * 60 * 24 * 365
Answer:
Step-by-step explanation:
1) x² - 8x + 5 = 0
2) No subtract 5 from both sides
x² - 8x + 5 - 5 = 0 - 5
x² - 8x = -5
3) Now find (8/2) = 4. Add 4² = 16 to both sides
x² - 8x + 16 = -5 + 16
x² - 8x + 16 = 11
4) (x - 4)² = 11
5) Take square root both sides
x - 4 = ±√11
x = 4 ±√11

1 + 2
Add the terms.
= 3
You seem to already see that you need to multiple x with the other numbers. When you start off solving it you'd get.. x-6=x2(to the power of) + 6x . Then just move the equation over from the left to the right. and solve, I've got -6+x2(power of 2)+7x, that's it
