Answer:

y=8x

Step-by-step explanation:

To find the slope, or m, pick 2 points.

I chose (0, 0) and (2, 16)

The use the slope formula

16-0/2-0

16/2

to find the y-intercept, or b, find the point where the line crosses the y-axis, which is (0, 0). Take the y-coordinate, which is 0.

So,

y=8x+0

or y=8x

You need to buy 8 packages of meat for a cookout. A package of hot dogs costs $2.19 and a package of hamburgers costs $5.89. You

Daniel [21]

Answer:

1.89x + 5.19y = 31.62.

Step-by-step explanation:

Let the pagke of hot dags be x

Let the pakage of hamburgers be y

Now they total up tp 8 packages.

xEliminate the cost

x+y=8

y=8-x

Cost of hotdogs = $1.89

Cost of hamburgers = $5.19

1.89x+5.19y=31.62

1.89x+5.19(8-x)=31.62

1.89x+41.52-5.19=31.62

-3.3x=--9.9

x=3

y=8-3

y=5

A cable that weighs 6 lb/ft is used to lift 500 lb of coal up a mine shaft 400 ft deep. Find the work done. Show how to approxim

stealth61 [152]

Answer:

8.2 *10^5 ft lb

Step-by-step explanation:

Wcoal = 800*500 = 400000 = 4*10^5 ft lb

$Wrope =\int\limits^{400}_0 {6(400-y)} \, dy$

Using a right Riemann sum

The width of the entire region to be estimated = 400 - 0 = 400

Considering 8 equal subdivisions, then the width of each rectangular division is 400/8 = 50

F(x) = 6(400-y)

$\left[\begin{array}{cccccccccc}x&0&50&100&150&200&250&300&350 &400\\f(x)&2400&2100&1800&1500&1200&900&600&300&0\end{array}\right]$

Wrope = 50(2100) + 50(1800) + 50(1500) + 50(1200) + 50(900) + 50(600)

+ 50(300) + 50(0) = 420000 = 4.2 * 10^5 ft lb

Note: Riemann sum is an approximation, so may not give a accurate value

work done = Wcoal + Wrope= 4*10^5+ 4.2 * 10^5 = 8.2 *10^5 ft lb

Jack jogs at an average speed of 40 m/min. How far does he<br> jog in 1.2 hours?<br> m

marusya05 [52]

So basically you would create an equation from y=mx+b, so you would put 40 in for m and to find x you convert 1.2 hours into minutes which is 72 minutes. so multiply 40 times 72 and that’s how far Jack will be i believe. Jack jogged 2,880m/min. Hope it’s correct.
