Answer:
Calculators from the beginning of the third week to the end of the fourth week = 4048.
Step-by-step explanation:
We know that the rate of production of these calculators after t weeks is given by
To find the number of calculators that have been produced in a period, we need to take the integral of the function above; the desired time is t=2 (beginning of third week) to t=4 (end of the fourth week). Therefore, the number of calculators produced in the given time is
Substitute 
and 
, observe that the limits of integration will change
≈ 4048
Answer:
48,96,192
Step-by-step explanation:
We see that each term is twice of the previous term. Using this principle, we get the next three terms, which are 48,96,192.

Answer: -2.8
Step-by-step explanation:
3t-(8/5) * 4-t < -7
(15t-8)/5 * 4-t < -7
((15t-8)(4-t))/5 < -7
(15t^2)-28t-32< -7
(15t^2)-28t-32-7< 0
(15t^2)-28t-39< 0
Using the quadratic/almighty formula
t= (-b +- ((b^2)-4ac)^(1/2)/2a)
a=15, b=-28, c=-39
t= (-(28) +- (((-28)^2)-4(15)(-39))^(1/2))/2(15))
t= -2.8 or t= 0.9
Since
t<0, then t= -2.8
