Answer:
y-intercept is 10
slope of line is 7
Explanation:
The general form of the linear equation is:
y = mx + c
where:
m is the slope
c is the y-intercept
Now, the given equation is:
y = 7x + 10
Comparing the given equation with the general form, we will find that:
m = 7 .............> This means that the slope of the line is 7
c = 10 ............> This means that the y-intercept is 10
Now, the y-intercept here means that the initial number of points at time = 0 (x=0) is 10 points.
The slope here means that the rate increases by 7 points each second
Hope this helps :)

Answer:
The value of the damping coefficient γ is (6/19)√29, which is approximately 1.70058.
Step-by-step explanation:
Given that a certain vibrating system satisfies the equation
u'' + γu' + u = 0
We wish to find the value of the damping coefficient γ for which the quasi period of the damped motion is 90% greater than the period of the corresponding undamped motion.
The period of the undamped motion T is 2π
The quasi period T_d is (4π)/√(4 - γ²)
Since the quasi period is 90% greater than the period of the undamped motion, we have
T_d = 1.9T
So that we can finally obtain
γ as 1.70058.

Some possibilities:
r = (9√d)/2, so f(d) = <span>(9√d)/2
r = 9d^2/16, so f(d) = </span><span>9d^2/16</span>
r = 9(2^d)/16, so f(d) = 9(2^d)/16
These are examples of non-linear functions of d which fit the description. I think that is what you are asking, but comment if I'm wrong?
