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

, observe that the limits of integration will change

≈ 4048
Answer:
A) -20
Step-by-step explanation:
distribute the 4y and the -4 to the parentheses
16y^2 -16y+16y-20-16y^2
combine like terms
16y^2-16y^2=0
-16y+16y=0
-20

Answer:
-4x^3 - 4y^2
Step-by-step explanation:
-5y^2 + 5 - 4 - 4y^2 + 5y^2 - 4x^3 - 1
= -4x^3 -4y^2
Answer:
22
Step-by-step explanation:
Missy has 156 cards in total. Since we know she has 4 times as many as them, we divide 156 by 4
156/4= 39
Ashe has 17 cards and we still don't know how many Caleb has. Since we know that they have 39 cards together, we need to subtract Ashe's cards to find how many Caleb has
39-17=22
Let's check our work
Caleb has 22 cards
Ashe has 17 cards
Together they have 39
Which is 4 times less than how many cards Missy has
Missy has 156 cards
We are correct!
