The first question is (7)
velocity is the slope (which can be calculated after finding the derivative) → given function f(x), velocity = f'(x).
acceleration is the slope of the velocity (which can be calculated after finding the derivative of the velocity) → given function f(x), acceleration is f''(x)
**************************************************************************************************
1a) A → B
f(x) = 
f'(x) = 
1b) B → C
f(x) = 
f'(x) =
= -5
1c) C → D
f(x) = 20
f'(x) = 0
Hope this helps!
Answer:
=20s³+50s²+32s+6
Step-by-step explanation:
We multiply each of the term in the initial expression by the the second expression as follows:
4s(5s²+10s+3)+2(5s²+10s+3)
=20s³+40s²+12s+10s²+20s+6
Collect like terms together.
=20s³+50s²+32s+6
Answer: 106
Step-by-step explanation:
53-(-53)
= 53 + 53 [ the product of - and - gives +]
= 106
