Volume:
Rectangular prism on top of the other rectangular prism:

Length • Height • Width

Substitute

2 • 1 • 6 = 12

Bottom rectangular prism:

Length • Width • Height

Substitute

8 • 4 • 6 = 192

Add

192 + 12 = 204 cm^3

Surface area:

Upside down T: 2((8 • 4)+(2•1)) = 68

Top down part 1: (2 • 6) = 12

Top down part 2: 2(3 • 6) = 36

Side part 1: 2(6 • 4) = 48

Side part 2: 2(6 • 1) = 12

Bottom: 8 • 6 = 48

Add: 68 + 12 + 36 + 48 + 12 + 48 = 224 cm^2

Volume: 204 cm^3

Surface area: 224 cm^2

Hi, can someone please help, and possibly explain the answer please.
mr_godi [17]

Answer:

x=\frac{-(-2)\±\sqrt{(-2)^2-4(3)(0)} }{2(3)}

Step-by-step explanation:

Quadratic formula: x=\frac{-b\±\sqrt{b^2-4ac} }{2a} when the equation is 0=ax^2+bx+c

The given equation is 1=-2x+3x^2+1. Let's first arrange this so its format looks like y=ax^2+bx+c:

1=-2x+3x^2+1

1=3x^2-2x+1

Subtract 1 from both sides of the equation

1-1=3x^2-2x+1-1\\0=3x^2-2x+0

Now, we can easily identify 3 as a, -2 as b and 0 as c. Plug these into the quadratic formula:

x=\frac{-b\±\sqrt{b^2-4ac} }{2a}\\x=\frac{-(-2)\±\sqrt{(-2)^2-4(3)(0)} }{2(3)}

I hope this helps!

State the domain of the rational function. f(x) = seventeen divided by quantity five minus x
alexandr1967 [171]

If we are going to write the equation in its mathematical form, we will see that it becomes,

<span>                                        f(x) = 17/(x – 5)</span>

The domain of the function is the number of x that would allow us to solve the equation and get a real value for f(x). In this equation, x can take any real numbers so long as it is not 5. This is because 5 – 5 in the denominator will lead to 0 which in turn makes the equation indefinite.

At an output level of 50 units per day, a firm has average total costs of $60 and average variable costs of $35. Its total fixed
e-lub [12.9K]

Answer:

$ 1250

Step-by-step explanation:

output = 50 units per day

average total cost = $ 60

total cost = output × average total cost =50 × 60 = $ 3000

total variable cost = output × average variable cost = 35 × 50 = $ 1750

total cost = total fixed cost + total variable cost

total fixed cost = total cost - total variable cost = $ 3000 - $ 1750 = $ 1250
