If f(x)=2x and g(x)= 1/x, what is the domain of (f*g) (x)
postnew [5]

Answer:

The domain of (f*g) (x) is the set of all real numbers; ( -∞, ∞)

Step-by-step explanation:

(f*g) (x) simply means we obtain the product of f(x) and g(x). We are given that;

f(x)=2x

g(x)= 1/x

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

(f*g) (x) = 2x * 1/x = 2

This is a horizontal line defined everywhere on the real line. The domain of  (f*g) (x) is thus ( -∞, ∞)

−4+bx=2x+3(x+1) In the equation shown above, b is a constant. For what value of b does the equation have no solutions?
Likurg_2 [28]

Answer:

b=5

Step-by-step explanation:

−4+bx=2x+3(x+1)  (expand parenthesis first, i.e PEDMAS)

−4 + bx = 2x + 3x + 3

−4 + bx = 5x + 3   (move all x terms to one side and constants to another)

5x - bx = - 4 -3

5x - bx = - 7  (factor out x)

(5 - b)x = - 7

x = -7 / (5-b)

we can see that 5-b is in the denominator. Recall that for a fraction, the denominator cannot be zero otherwise the expression is undefined. (i.e no solutions)

hence the  expression is undefined if,

(5-b) = 0

or b = 5

Hello please help!!!!!!!
raketka [301]

<u>Answer:</u>

The length of VI = 4 cm

<u>Solution: </u>

The plot is like a quadrilateral and the fences are built on the diagonal

We know that for quadrilateral both the diagonals are in same height,  

So as per the picture, GH = FI

Now we know that GV = 6.55, FV = 5.84, VH = 3.27

Hence,

GH = FI

\Rightarrow GV + VH = VI + VF

\Rightarrow 6.55 + 3.27 = VI + 5.84

\Rightarrow VI = 6.55 + 3.27 - 5.84

\Rightarrow VI = 3.98

<u><em>Rounding off: </em></u>

  • If the number that we are rounding is<em> followed by 5 to 9</em>, then the number has to be <em>increased to the next successive number</em>.
  • If the number that we are rounding is <em>followed by 1 to 4</em>, then the number has to <em>remain the same</em>.

Here the number to be round off is 3.98, 9 belongs to the first category stated above. So, 3 is increased to 4.

Hence, the length of VI = 4 cm.
