Step-by-step explanation:

Cardboard needed to make tube =

Circumference of Circle base (remember the base is hollow therefore there is no area needed.) x Length of Tube

given r = 2.25cm

L = 24cm

Cardboard needed =

2\pi \: rl =  \\ 2\pi(2.25)(24) \\  = 2\pi(54) \\  = 108\pi {cm}^{2}  \\  = 339 {cm}^{2}

Line BC has an equation of a line Y equals 2X +3 and F has an equation of a line Y equals -1/2 x+4 these two equations represent
Masja [62]

Answer:

Lines BC and F represent perpendicular lines

Step-by-step explanation:

we have

<em>Line BC</em>

y=2x+3

the slope of the line BC is m=2

<em>Line F</em>

y=-(1/2)x+4

the slope of the line F is m=-1/2

we know that

If two lines are perpendicular, then the product of their slopes is equal to -1

so

m1*m2=-1

we have

m1=2 -----> slope line BC

m2=-1/2 -----> slope line F

Find the product of their slopes

(2)(-1/2)=-1

therefore

Lines BC and F represent perpendicular lines

Find the maximum and minimum values by evaluating the equation
dezoksy [38]

Answer:

min = -9

max =3

Step-by-step explanation:

C = x-3y

x ≥0

x≤3

y≥0

y≤3

The minimum will be be when x is smallest and y is at its max

x =0 and y = 3

C = 0 - 3(3)

C = 0-9 = -9

The minimum is -9

The maximum occurs when x is largest and y is smallest

x =3 and y = 0

C = 3 - 3(0)

C = 3-0 = 3

The max is 3
