HELP! LOOK AT THE IMAGES BELOW

sineoko [7]

Answer:

(g+f)(x)=(2^x+x-3)^(1/2)

Step-by-step explanation:

Given

f(x)= 2^(x/2)

And

g(x)= √(x-3)

We have to find (g+f)(x)

In order to find (g+f)(x), both the functions are added and simplified.

So,

(g+f)(x)= √(x-3)+2^(x/2)

The power x/2 can be written as a product of x*(1/2)

(g+f)(x)= √(x-3)+(2)^(1/2*x)

We also know that square root dissolves into power ½

(g+f)(x)=(x-3)^(1/2)+(2)^(1/2*x)

We can see that power ½ is common in both functions so taking it out

(g+f)(x)=(x-3+2^x)^(1/2)

Arranging the terms

(g+f)(x)=(2^x+x-3)^(1/2) ..

Compute the norm of v when v = (-8,7,4)

dexar [7]

Answer:

the norm of V = =11.357816691601..

Step-by-step explanation:

$\left\vert \overrightarrow{V} \right\vert =\sqrt{\left( -8\right)^{2} +\left( 7\right)^{2} +\left( 4\right)^{2} }$

$=\sqrt{64+49+16}$

$=\sqrt{129}$

$=11.357816691601...$

Solve the following in-equations and graph the solution on the number line

OverLord2011 [107]

Answer:

Step-by-step explanation:

$\frac{x-4}{3}$ ≥ - 2

x - 4 ≥ - 6

x ≥ - 2

<em>x ∈ [ - 2 , ∞ )</em>

2 - 6x < 32

- 6x < 30

x > - 5

<em>x ∈ ( - 5 , ∞ )</em>
