Maybe 6+4x??? Not sure though
Step-by-step explanation:
Answer=B
proving:
503,000 > 10
so we look for a number
less than 10
=5.03 ×10-5
the other three zeros are not
needed.
Thank you
It examines the knowledge of the basic calculation. According to the topic, parallelogram ABCD & AB//CD
so AB=CD
Since MAB=-5 so MCD = MAB=-5 then the answer might be “-5”
Answer:
1 m/s
Step-by-step explanation:
the area of the triangle = A = ¹/₂ab
where a is the distance covered by the first person and b is the distance covered by the second person. since they walk at the same speed, then a = b, so our formula can be changed to A = ¹/₂x²
now we find the derivative of both sides:
dA/dt = ¹/₂ ⋅ dx²/dt
dA/dt = ¹/₂ ⋅ 2x ⋅ dx/dt
dA/dt = x ⋅ dx/dt = x ⋅ velocity
we are told that x = 5 m, and dA/dt = 5 m²/s
velocity = dA/dt / x
velocity = 5 m²/s / 5 m = 1 m/s
