So, (n о v о s)(x) is |\sqrt{2^x}|+2

Option C is correct.

Step-by-step explanation:

We are given:

n(x)=2^x, \,\,s(x)=\sqrt{x}, \,\,v(x)=|x|+2

We need to find (n о v о s)(x)

(n о v о s)(x) is equal to: n(v(s(x)))

First we will find v(s(x))

Plugging s(x) into v

=|\sqrt{x}|+2

Now finding n(v(s(x)))

Putting v(s(x)) into n(x)

=|\sqrt{2^x}|+2

So, (n о v о s)(x) is |\sqrt{2^x}|+2

Option C is correct.

Whats the slope of a perpendicular line that passes through the lines (29,24) and (3,4)
kolbaska11 [484]
I believe the answer is 1.3
explanation: to find slope you do x’s over y’s so you would have

29-3
———
24-4

which gets you

26
——
20

and simplified its 1.3. Sorry if it is wrong :/.

What is an equation of the line that passes through (2,-3) and is perpendicular to y=x-5
Digiron [165]

y = -x - 1 is the equation of the line that passes through (2,-3) and is perpendicular to y = x - 5

<em><u>Solution:</u></em>

Given that we have to write the equation of the line that passes through (2,-3) and is perpendicular to y = x - 5

<em><u>The equation of line in slope intercept form is given as:</u></em>

y = mx + c ------ eqn 1

Where, "m" is the slope of line and "c" is the y intercept

<em><u>Given equation of line is:</u></em>

y = x - 5

On comparing the above equation with eqn 1,

m = 1

We know that,

Product of slope of line and slope of line perpendicular to given line is equal to -1

Therefore,

1 \times \text{ slope of line perpendicular to given line } = -1\\

Slope of line perpendicular to given line = -1

<em><u>Now we have to find the equation of line with slope -1 and passing through (2, -3)</u></em>

Substitute m = -1 and (x, y) = (2, -3) in eqn 1

-3 = -1(2) + c

-3 = -2 + c

c = -3 + 2

c = -1

<em><u>Substitute m = -1 and c = - 1 in eqn 1</u></em>

y = -x - 1

Thus the equation of line is found
