Answer:
5.266 secs
Step-by-step explanation:
Lets assume ; p(t) = t^-3 + 2^2 + ( 3/2 ) is the particle position along x-axis
time interval [ 0, 4 ]
Average velocity = Displacement / time
= p( b ) - p( a ) / b - a -------- ( 1 )
where a = 0 , b = 4 ( time intervals )
Back to equation 1
Average velocity = [ ( 4^-3 + 4 + (3/2) ) - ( 0 + 4 + (3/2) ) ] / 4
= 3.9 * 10^-3 ----- ( 2 )
Instantaneous velocity = d/dx p(t)
= - 3/t^4 ------ ( 3 )
To determine the time that the instanteous velocity = average velocity
equate equations (2) and (3)
3.9*10^-3 = - 3 / t^4
t^4 = - 3 / ( 3.9 * 10^-3 ) = - 769.231
hence t = = 5.266 secs
we ignore the negative sign because time can not be in the negative
(x-7)(4x^2-x+3)
4x^3-x^2+3x-28x^2+7x-21
4x^3-29x^2+10x-21
Answer:
For a 9000 people, the approximate number of people for whom the medicine will be effect is 8432 people
Step-by-step explanation:
Here we have probability is given by
Probability = Where:
Number of success = 3982 and
Number of trials = 4250. therefore;
Therefore, when the medicine is used on 9000 people, the approximate number of people for whom the medicine will be effect is given by;
or ≈ 8432 people.
Answer:
since the graph is in the direction it is the only number choice it acctually passes through would be -2.
X= the number
.05=.1x Set up into an equation.
5/100= 1/10x Divide 5/100 by 1/10 to find x.
5/10=x You get x
x=1/2 Reduce into simplest form.
