The option gpe is best when the contracted volume is below 3750037500 units ​(enter your response as a whole​ number).the option
frozen [14]

Answer:

Find attached missing part of the question:

The option gpe is best when the contracted volume is below 31250  units

The option fms is best when the contracted volume is between 31,250 and 230,000  units ​

The option DM is best when contracted volume is above 230,000 units

Step-by-step explanation:

let x represent the volume produced in each of the three options:

Total cost(TC) =fixed cost+(variable per unit*x)

for general purpose equipment:

TC=125,000+18x equation 1

for flexible manufacturing system

TC=250,000+14x equation 2

for dedicated machine

TC=480,000+13x equation 3

if we set equations 1 and 2 together

125,000+18x=250,000+14x

If we equate equations 2 and 3 together

250,000+14x=480,000+13x

14x-13x=480,000-250,000

x=230,000

18x-14x=250,000-125,000

4x=125,000

divide both sides y 4

x=125,000/4=31250

What is the equation of the circle with center (0, 0) that passes through the point (–4, –6)?
eimsori [14]

Answer:

Option 4: x^2+y^2 = 52

Step-by-step explanation:

Given

Centre at origin

Point on circle = (-4, -6)

The distance between origin and point on circle will be the radius of the circle

So,

r = \sqrt{(x_2-x_1)^{2}+(y_2-y_1)^{2}}\\r= \sqrt{(-4-0)^2+(-6-0)^2} \\r = \sqrt{(-4)^2+(-6)^2}\\r = \sqrt{16+36} \\r = \sqrt{52}

As the center is at origin the standard equation will be:

x^2+y^2 = r^2\\

Putting the value of r

x^2+y^2 = (\sqrt{52})^2\\x^2+y^2 = 52

Hence, last option i.e. Option 4 is correct ..

Snowcat [4.5K]
X = -7

3 • 7 = 21

-3 • (-7) = 21

If you multiply two negative numbers you’ll end up with a positive. Thus, - 3 (-7) = 21.
