Answer:

V = 4x^3-39x^2+93.5x

Domain: 0 < x < 4.25

Using the graph the maximum volume is about V = 66 inches ^3  at about x = 1.6  

Step-by-step explanation:

V = l*w*h

The length is 11 -2x

The width is 8.5 -2x

The height is x

V = ( 11 -2x) ( 8.5 -2x) x

FOIL ( first outer inner last)

V = (93.5 -22x - 17x +4x^2) x

Combine like terms

V =( 4x^2-39x+93.5)x

Distribute the x

V = 4x^3-39x^2+93.5x

The domain is the values that x can take

Looking at the picture

2x can be no largest than 8.5 or there will be no width

2x < 8.5

x < 4.25

If x ≤ 0 there is no height so x > 0

0 < x < 4.25

Using the graph the maximum volume is about V = 66 inches ^3  at about x = 1.6

The correct answer is 0.48 because as you can tell the probability of it landing on heads is just a little bit below the probability of getting tails. Hope I helped!

I NEED HELP PLEASE, THANKS! :) Use the graph to determine the domain and range of the relation, and state whether the relation i
Mandarinka [93]

Answer:

Domain: All numbers greater than or equal to 0. By definition, the domain of a graph, is the possible x values.

Range: All real numbers. By definition, the range is all possible x values.

Not a function. A function has y value for every x value.

Find X <br><br> Simplify answer type exact number or use radicals as needed
satela [25.4K]
On a right triangle, to find one missing side you can use this equation
a^2 + b^2 = c^2

a and b are the sides next to the right angle, and c is the hypotenuse (side not connected to right angle).

You first need to find the length of the dotted line before finding x. This is because to be able to use the above formula, you have to know the length of two out of three of the sides.

To solve the length of the dotted line, note that it also makes a triangle with the 5 unit line and the 5 √5 unit line. You can plug these numbers into the formula.
(5)^2+b^2=(5 √5)^2
25+b^2=125
b^2=100
b=10

Now that you know the length of the dotted line is 10 units, you can now solve for x

(20)^2+(10)^2=x^2
400+100=x^2
500=x^2
x= √500, which equals 22.361
