Answer: I don’t speak your languag ;-;
Step-by-step explanation:
81 is the perfect square because 9 * 9
Answer:
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 = 
, height of the box = x
Volume of square box = Area * height = 
Differentiating the above equation and equating it to zero, we get –
d/dx 
d/dx
= d/dx 
d/dx 
On solving above equation, we get –
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
Step-by-step explanation:
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)
