Jamie and Hudson took a road trip to the beach. Their total distance traveled after getting on the highway can be found using th

lukranit [14]

The total distance is an illustration of a linear function.

(1) Why the relationship is a function

The relationship is a function because all input values of h, have exactly one corresponding output value of d

(2) The function type

The function is a discrete function, because the number of hours is an integer, and it cannot take decimal values (in this case)

(3) The domain for a drive of 8 hours

The domain is the set of time the girls drive.

So, the domain is: [0,8]

(4) The range

The function is given as:

$d = 55h +10$

When h = 0,

$d = 55(0) +10 = 10$

When h = 8,

$d = 55(8) +10 = 450$

So, the range is: [10,450]

(5) The graph

See attachment

(6) The slope

A linear function is represented as:

$y = mx + c$

Where:

m represents the slope.

So, by comparison:

$Slope = 55$

The slope in this case represents the distance travelled per hour

(7) The y-intercept

In (6) above, c represents the y-intercept.

So, by comparison:

$c = 10$

The y-intercept in this case represents the initial distance

Find the dimensions of the open rectangular box of maximum volume that can be made from a sheet of cardboard 41 in. by 22 in. by

BlackZzzverrR [31]

Answer:

V(max) = 1872.42 in³

Step-by-step explanation:

Let call " x " the side of the cut square in each corner, then the sides of rectangular base ( L and W )will be

L = 41 - 2*x and

W = 22 - 2*x x = the height of the open box

Volume of the box is

V(b) = L*W*x

And volume of the box as a function of x is:

V(x) = ( 41 - 2*x ) * ( 22 - 2*x ) * x

V(x) = ( 902 -82*x - 44*x + 4*x² ) * x ⇒ V(x) = ( 902 -126*x + 4x²) * x

V(x) = 902*x - 126*x² + 4x³

Taking derivatives on both sides of the equation we get:

V´(x) = 902 - 252*x + 12 *x²

V´(x) = 12*x² - 252*x + 902

V´(x) = 0 ⇒ 12*x² - 252*x + 902 = 0

A second degree equation solving for x (dividing by 2 )

6*x² - 126* x + 451 = 0

x₁,₂ = ( 126 ± √ 15876 - 10824 ) / 12

x₁,₂ = ( 126 ± 71,08 ) / 12

x₁ = 16 in ( we dismiss this value since 2x > than 22 there is not feasible solution for the problem)

x₂ = 54.92/12 ⇒ x₂ = 4,58 in

Then maximum volume is:

V(max) = 31.84 * 12.84 * 4,58

V(max) = 1872.42 in³
