Answer:

Step-by-step explanation:

Start by multiplying everything by 320, so that the y gets a unit factor:

$\frac{320}{16}x + \frac{320}{320}y - 29\cdot320 = 0$

simplify

$20x + y - 9280 = 0$

Now isolate y on the left:

$y = 9280 - 20x$

Change the equation y= in to a function of x:

$f(x) = 9280 - 20x$

Max is stacking logs at his campground for firewood. After his first load of logs, he has 12 logs on the stack. After his sevent

Natasha2012 [34]

Answer:

Let L(n) be the function that gives the amount of logs stacked after n loads.

L(n) = 12 + 8(n-1)

Step-by-step explanation:

Let L(n) be the function that gives the amount of logs stacked after n loads.

Let's call for the moment the first load as L(0)

L(0)= 12

Let r be the number of logs carried in each load, then

L(n) = 12 + nr

Since L(6) (the seventh load) equals 60, we have

60 = 12 + 6r, and r = 8.

So a function for the number of loads starting from n=0 would be

L(n) = 12 + 8n

If we want to start with n=1, we simply change the variable

L(n) = 12 + 8(n-1) (n=1,2,3,...).

So L(1) = 12, L(2) = 20, L(3) = 28,...L(7) = 60 and so on.

Area of a Triangle

jek_recluse [69]

Answer:

3.51 (round to the nearest hundreds)

Step-by-step explanation:

PART A

slope of the line passing through AC : (6-1)/(1-2) = 5/-1 = -5

equation of the line passing through B and perpendicular to AC:

y-3 = 1/5(x-3)

y-3 = 1/5x -3/5

y = 1/5 x - 3/5 + 3

y = 1/5 x + (-3+15)/5

y = 1/5 x + 12/5

PART B

line that passes through the points A and C

y-1 = -5(x-2)

y = -5x+10 + 1

y = -5x + 11

Interception of the lines

y = 1/5x + 12/5

y = -5x + 11

-5x + 11 = 1/5x + 12/5

-25x +55 = x + 12

26x = 43

x = 43/26

y = -5(43/26) + 11

y= -215/26 + 11

y = (-215+286)/26 = 71/26

D (1.65, 2.73)

PART C

AC = $\sqrt{(1-2)^2 + (6-1)^2} = \sqrt{1 + 25} = \sqrt{26}$ = 5,09902

BD = $\sqrt{(3-1.65)^2 + (3-2.73)^2}$ = 1,376735

PART D

AREA = (5,09902 * 1.376735)/2 = 3,509999

a rectangle has an area of 7/8 square units if the width is 7/16 unit what is the length of the rectangle in units?

djyliett [7]

Answer:

$Length=2 units$

Step-by-step explanation:

Given :

Area of the rectangle = $\frac{7}{8}$ square units

Width of the rectangle= $\frac{7}{16}$ units

Area of the rectangle= Length* Width

$\frac{7}{8} =Length*\frac{7}{16}$

Multiplying $\frac{16}{7}$ both the sides

$\frac{7}{8} *\frac{16}{7} =Length$

$Length=\frac{16}{8}$

$Length=2 units$

The length of the rectangle is 2 units
