Answer:

Step-by-step explanation:

Potential energy=stored energy so say when the roller coaster stops somewhere they are storing energy.

In then when they just go down there would now be using kinetic energy.

Hope this helps have a great afternoon:)

Use the formula R = 6e12.77x, where x is the blood alcohol concentration and R, as a percent, is the risk of having a car accide

tester [92]

$R=6e^{12.77x}$
$50=6e^{12.77x}$
$\frac{50}{6}= e^{12.77x}$
$log \frac{50}{6}=log( e^{12.77x})$
$0.920818754=12.77x$
$x=0.07$

Answer:

C = 14 is the minimum value

Step-by-step explanation:

Sketch the inequalities using

2x + y = 20

with x- intercept = (10, 0) and y- intercept = (0, 20)

2x + 3y = 36

with x- intercept = (18, 0) and y- intercept = (0, 12)

Solve 2x + y = 20 and 2x + 3y = 36 simultaneously to find

The point of intersection at (6, 8))

The vertices of the feasible region are at

(0, 20), (6, 8), (18, 0)

Evaluate the objective function C = x + y at each of the vertices

(0, 20) → C = 0 + 20 = 20

(6, 8) → C = 6 + 8 = 14 ← minimum value

(18, 0) → C = 18 + 0 = 18

Minimum value is C = 14 when x = 6 and y = 8

Six increased by two times the difference of four

Mrrafil [7]

16x

Step-by-step explanation:

6 increased by 2 --> 6+2

difference of 4 and 2 --> 4-2

first part times the second part --> 6 + 2 (4-2)

times a number --> • x

put it all together --> (6+2)(4-2) • x or 16x

X-2y+z=5 <br>3x+3y-2z=-6 <br>2x-y+3z=11 <br>find x+y+z

BartSMP [9]

x - 2y + z = 5 | *2
⇒ 2x - 4y+ 2z=10
3x + 3y - 2z = - 6 } I sum up these relations
--------------------------------
2x+3x - 4y+3y+2z-2z=10-6
5x - y = 4 (1)

3x + 3y - 2z = - 6 | *3 ⇒ 9x + 9y - 6z = - 18
2x - y + 3z = 11 | *2 ⇒ 4x - 2y + 6z= 22 I sum up these
----------------------------------
⇒ 9x+4x+9y-2y-6z+6z= 4
13x+ 7y= 4 (2)
I write (1) and (2)
5x - y = 4 | *7
35x - 7y= 28
13x+7y=4
48x = 32
x= 32/48=4/6 ( 32:8=4, 48:8=6)
x= 2/3
5x-y=4,
5*2/3-y=4
y=10/3 -4=10/3-12/3=-2/3
⇒ y= - 2/3
x - 2y + z = 5
2/3 - 2*(-2/3)+z=5
2/3+4/3+z=5
6/3+z=5
2+z=5
z=3
x+y+z=2/3-2/3+3=3

x+y+z=3
