Answer:
She read 250 words per minute.
Step-by-step explanation:
Simply divide the words read by the time took to read that amount = (2000/8) words per minute = 250 words per minute.
Hope this helped!
9/27 and 30%
Step-by-step explanation:
16/ 54 then reduced to 9/27
to find percent divide 16/54 to get 0.296 then round that to 0.30 multiple by 100 to change to percent which is also just moving decimal over 2 places so 30%
Answer:
(-3, 5)
Step-by-step explanation:
plug y = 5 into the second equation
x(5) = -15
5x = -15
x = -3
(-3, 5)
As the fellow above said, the particle does make a U-turn at the vertex, and we can find that out by getting the derivative of s(t) and zeroing it out to get the point of the horizontal tangent.
Bearing in mind that ds/dt is really v(t) or the velocity equation, so when we zero out the ds/dt, is the same as saying the velocity went to 0, since it got zeroed out, and then the particle goes over the vertex and changes direction.

the negative acceleration value, simply means a decreasing rate of change, so, it means the particle is slowing down and possibly coming to a stop before changing direction again.
