Find the volume of the larger cuboid using given measurement in smaller one.(cu.cm=cubic centimeter
kompoz [17]

Answer:

  c.  12 cu. cm.

Step-by-step explanation:

The larger cuboid is an array of 4 × 3 = 12 of the smaller ones. The volume of the smaller cube is (1 cm)³ = 1 cu. cm. The volume of the larger cuboid is 12 times that value:

  12 × 1 cu. cm = 12 cu. cm.

If f(x)=3/x and g(x)=3x, which of the following statements is true?
bagirrra123 [75]

Answer:

d. (g*f)(-9)=-1

Step-by-step explanation:

In this problem, we have two functions:

f(x)=\frac{3}{x}

and

g(x)=3x

The notation:

(f*g)(x) represents the composite function of f and g; this can be calculated by using the output of g(x) as input for f(x), in other words:

(f*g)(x)=f(g(x))

Simiarly, the notation (g*f)(x) can be calculated by using the output of f(x) as input for g(x), mathematically:

(g*f)(x)=g(f(x))

Using the definitions of f(x) and g(x), we can derive an expression for the two composite functions here:

(f*g)(x)=f(g(x))=\frac{3}{g(x)}=\frac{3}{3x}=\frac{1}{x}

And

(g*f)(x)=3(f(x))=3(\frac{3}{x})=\frac{9}{x}

Now we can analyze the given statements:

a. (f*g)(2)=2  --> FALSE, because (f*g)(2)=\frac{1}{2}

b. (g*f)(2)=0  --> FALSE, because (g*f)(0)=\frac{9}{0}=\infty

c.(f*g)(9)=1  --> FALSE, because (f*g)(9)=\frac{1}{9}

d. (g*f)(-9)=-1 --> TRUE, because (g*f)(-9)=\frac{9}{-9}=-1
