Find the difference of functions s and r shown below. r(x) = -x² + 3x s(x) = 2x + 1 ( s-r)(x)=

Part 1)

Part 2)

Step-by-step explanation:

Part 1)

So we have the two functions:

And we want to find:

This is the same as:

Substitute:

So, our answer for Part A is:

Part 2)

Let's find our difference.

Distribute the -1:

Combine like terms:

Add:

And we're done!

c

step-by-step explanation:

a. 12.5 kg

step-by-step explanation:

f = ma

so

m = f/a = (2500 n)/(200 m/s²) = 12.5 kg

1 n = 1 kg·m/s²
