There's only one solution...the one you get when you divide both sides by 22 to solve for x. 902/22 = 41. That exponent on the x, the one you don't see, is a "1" which tells us that there is only 1 solution to this problem. If your x is squared, then you have 2 solutions; if it's cubed, you have 3, etc.

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:

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

Given that f(x) = 6x +1, find (f of)(-2).<br> (f of)(-2)<br> | (Simplify your answer.)

irakobra [83]

Answer:

(f of)(-2) = -65

Step-by-step explanation:

<u>Set up (f of)(-2)</u>

(f o f)(-2) = f(f(-2))

<u>Once you get (fof)(-2) you then have f(#)</u>

f(6(-2) + 1) = f(-11)

6(-11) + 1 = -66 + 1 = -65
