A sheet of cardboard 12 inches square is used to make an open box by cutting out squares of equal size from the four corners and
GrogVix [38]

Answer:

x=6+3\sqrt{2} is the size of the square

Step-by-step explanation:

Let the side of the square cut from the cardboard be “x”

Size of the square base = 12 -2x, height of the box = x

Volume of square box = Area * height = (12-2x)^2 * x

Differentiating the above equation and equating it to zero, we get –  

d/dx ((12-2x)^2 * x)

d/dx{(144 + 4x^2 -48x)*x}= d/dx (144x + 4x^3 -48x^2)

d/dx (144x + 4x^3 -48x^2) = 0

144+8x^2-96X= 0\\18 +X^2-12X = 0

On solving above equation, we get –  

x=6+3\sqrt{2}  \\ x=6-3\sqrt{2}

What is a possible volume for this cylinder if the diameter is 8 cm? Explain your reasoning.
lesantik [10]

Answer:

The formula for the volume of a cylinder is pi*r^2*h

r=radius= 1/2 diameter

h= the height

pi=3.14...

just get the height and plug it in

Sam is observing the velocity of a car at different times. After two hours, the velocity of the car is 50 km/h. After six hours,
kramer
For the acceleration to be uniform(gradient of equation constant), the car must have an existing velocity at time t = 0.
The acceleration (or gradient) = (54 - 50)/4
= 1 km/h
velocity = acceleration x time + initial velocity
50 = 1 x 2 + Vi
Vi = 48 km/h
The equation:
V(t) = t + 48
Where V(t) is the velocity at time t and t is the time.
The equation may be graphed by keeping time on the x axis and velocity on the y axis and starting the graph at the point (0 , 48)
