Answer:
the answer is B
Step-by-step explanation:
Let distance be s and velocity be v
s = 5t⁴ - 10t² + 6
We know velocity is the change in distance per unit time, so
v = ds/dt
v = 20t³ - 20t
Answer:
not necessarily
Step-by-step explanation:
Taking the square root of both sides, you have ...
±a = ±b
Those four cases resolve to two unique cases:
a = ±b
The given equation will be true if a = b or if a = -b. If a and b are constrained to have the same sign, then a=b is the only solution.
