We can subtract the function that represents the cost in 2000 from the function that represents the cost in 1990.

Doing this gives us (-20t^{2}+1000)-(-10t^{2}+1500)=\boxed{-10t^{2}-500}

The late fees for a school library are represented by the function c=.25d where c is the total cost and d is the number of days
RideAnS [48]

Answer:

City library charges 35 cents every day a book is late

School library charges 25 cents every day a book is late

Step-by-step explanation:

The late fees for a school library are represented by the function c=.25d where c is the total cost and d is the number of days a book is late.

The fees charged by a city library are shown in the table. Table is attached below

For the given table y intercept is 0

1 \cdot 0.35= 0.35\\2 \cdot 0.35= 0.70\\\\3 \cdot 0.35= 1.05\\

slope of the city library is 0.35

slope of school library is 0.25

y interept of both city and school library is 0

So we can say that there is no  charge for both library if they are not late

City library charges 35 cents every day a book is late

School library charges 25 cents every day a book is late

Answer:

Step-by-step explanation:

14/3 would become 70/15 and 11/5 would become 33/15 and 70+33 is 103, so 103/5. 103/15 - 22/15 = 81/15.

Randy rented a rectangular storage shed with the volume of 357 ft does it sheds height is 8 and 1/2 ft and the width of is 6 ft
ollegr [7]

Answer:

7 feets

Step-by-step explanation:

Volume of shed, V = 357 feet³

Height of shed, H= 8 1/2 fts

Width of shed, W = 6 ft

Using the relation :

Volume = Length * width * height

357 = L * 6 ft * 17/2 feets

357 feets³ = L * 51 feets²

L = 357 feets³ / 51 feets²

Length, L = 7 feets

Trava [24]

Answer:

domain - (-infinity,infinity)

range - (-infinity, 2]

axis of sym - x=-1

y int - (0,-1)

at what value (row 1) - (-1,2)

Step-by-step explanation:

domain is side to side, it never ends bc of the arrows

range is top to bottom, there is no bottom bc of the arrow, but it has a top at 2 (the value on the y axis)

the axis of sym is basically the line that runs through the vertex, it's where you could fold it in half and it would still match up
