Demetrious returned five library books last week, returned three books this week, then checked out 8 more books. He now has 12 l
Zanzabum

Answer:The number of books that he had before last week is 28

Step-by-step explanation:

Let x represent the number of books that he had before last week.

Demetrious returned five library books last week. This means that the number of books left is x - 5

He returned three books this week. This means that the amount of books left is x - 5 - 3 = x - 8

He then checked out 8 more books. This means that the amount of books left is x-8-8 = x - 16

He now has 12 library books. This means that

x - 16 = 12

x = 12 + 16 = 28

Find line tangent to y=xcosx at point (pi, -pi)
slamgirl [31]
1) slope of the line = derivative of the of the function at the given point.

y' = cosx - x cosx

Evaluate for x = pi => y' = cos(pi) - pi*cos(pi) = -1 - (pi*cos(pi)) = -1 + pi

Then slope = -1 + pi

Given point: (pi, -pi)

Equation:

y - (-pi) = [-1+ pi] (x - pi)

y + pi = -x +pi + xpi -pi^2

y = (pi-1)x - pi^2      .... this is the answer

The school band director has a budget $4,428.00 to spend on the band room, instruments, music, and uniforms. There are four sect
galina1969 [7]

Answer:

The amount of money left for each section to spend from the budget in additional costs if they follow exact of the options is

Option 1 - $497.5

Option 2 - $494.5

Option 3 - $500.5

The image to show the amounts to match to isn't attagged to the question, but these are the answers and they should be matched accordingly.

Step-by-step explanation:

We first calculate the amount left per section after following each of the options.

Budget $4,428.00

Option 1.

Repair and replace uniforms at $564.00 per section and spend $182.00 on music.

There are 4 sections, hence, total amount spent in this option:

4(564) + 182 = $2438

Amount of money left from the budget after spending = 4428 - 2438 = $1990

Amount left per section = (1990/4) = $497.5

Option 2

Repair and replace uniforms at $593.00 per section and spend $78.00 on music.

There are 4 sections, hence, total amount spent in this option:

4(593) + 78 = $2450

Amount of money left from the budget after spending = 4428 - 2450 = $1978

Amount left per section = (1978/4) = $494.5

Option 3

Repair uniforms at $287.00 per section, spend $856.00 for improving the acoustics in the band room, and spend $422.00 on music and repairing instruments.

There are 4 sections, hence, total amount spent in this option:

4(287) + 856 + 422 = $2426

Amount of money left from the budget after spending = 4428 - 2426 = $2002

Amount left per section = (2002/4) = $500.5
