D, it decreases by 6 every time while the others are multiplied by number
Answer:
Step-by-step explanation:
Given is a Differential equation as
To bring it to linear form we can divide the full equation by x
This is of the form
y'+p(x) *y = q(x)
p(x) = 1/x
So find
Solution is
Use the initial value as y(e) =1
So solution is
Answer:
4
Step-by-step explanation:
First, I'd like to say that this question is flawed because the diameter of the spool changes as you pull the line out. Some would argue it's negligible I suppose.
At any rate, assuming there's a magic spool where the diameter doesn't change, let's find the cicumference so we can find the length of one wrap around the spool.
circumference = 2*pi*r = 2 * pi * 4cm = about 25.133 cm
Now if it turns 16 times we'll have 16 times the circumference.
16 * (25.133 cm)
= 402.128 cm
(11,1) because if you plug in x and y this answer is the only one that gives you 18 in the end
