Let us revise the chain rule
If = a and = b, then
= ÷ =
∵ y = x² + 1
- Use the differentiation to find
∴ = 2x
∵ x = -1
- Substitute x by -1 in
∴ = 2(-1)
∴ = -2
∵ = ×
∵ = 2 cm/s
∴ = (-2) × (2)
∴ = - 4 cm/s
Answer:
Train got a raise of 16%
Step-by-step explanation:
To find this, start by taking the equation for percent change
(New - Old)/Old * 100 = % Change
Now plug in known values
(580 - 500)/(500) * 100 = % change
80/500 * 100 = % change
.16 * 100 = % change
16 = % change
