A set of bookshelves rests on a hard floor surface on four legs, each having a cross-sectional dimension of 3.0×4.1cm in contact
tatiyna

Answer:

5.22\cdot 10^5 Pa

Step-by-step explanation:

The pressure exerted by an object is given by:

p=\frac{F}{A}

where

F is the magnitude of the force

A is the area of the surface perpendicular to the force

In this problem, the force is the weight of the books + the shelf, which is given by

F=mg

where

m = 262 kg is the total mass

g=9.8 m/s^2 is the acceleration of gravity

Substituting,

F=(262)(9.8)=2568 N

The area of the four legs is:

A=4(3.0 cm\cdot 4.1 cm)=4(12.3 cm^2)=49.2 cm^2 = 49.2\cdot 10^{-4} m^2

Therefore, the pressure exerted on them is:

p=\frac{F}{A}=\frac{2568}{49.2\cdot 10^{-4}}=5.22\cdot 10^5 Pa

The graph of f(x) = x2 is shifted 3 units to the left to obtain the graph of g(x). Which of the following equations best describ
ANTONII [103]

Answer:

g(x) = (x + 3)^2

Step-by-step explanation:

When a function is shifted to the left or right we can think of a change of units, like a new independent variable is used.

If we have a quadratic function

f(x)=x^2

and the graph is shifted 3 units to the left, then we can think of a new unit u that is:

g(x)=u^2

The vertix of this parabola, that happens for u=0, happens for x=-3, as the graph is shifted 3 units to the left.

Then, the relation between u and x is:

u-x=0-(-3)=3\\\\u=x+3

We can use this relation in the new graph and replace u as:

g(x)=(x+3)^2
