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.

Find a pair of polar coordinates for the point with rectangular coordinates (5, –5).
Elanso [62]

Answer:

(5*sqrt(2), 5pi/4)

Step-by-step explanation:

In Polar coordinates, tan(theta)=y/x and r=sqrt(x^2+y^2)

tan(theta)=-5/5=-1. Theta=5pi/4

r=sqrt(5^2+5^2)=5*sqrt(2)

Hence the Polar coordinate is (5*sqrt(2), 5pi/4)

PLS HELP A friend says that the recursive formula for the geometric sequence $1,-1,1,-1,1,is an+1x(-1)^n-1. Explain your friend'
Leno4ka [110]

Answer:

For a geometric sequence with recurrence of the form a(n)=ra(n-1) where r is constant, each term is r times the previous term. This implies that to get from the first term to the nth term, we need to multiply by n-1 factors of r.

Step-by-step explanation:

hii

you are looking so h*t and s**y..

As a fraction (all of the bellow) <br> 6.7<br> -0.92<br> -0.1<br> -5.05
iren2701 [21]

Answer:

6.7 = 6 \frac{7}{10}

-0.92= -\frac{23}{25}

-0.1= -\frac{1}{10}

-5.05=-5\frac{1}{20}

Step-by-step explanation:

:-)

First rewrite the decimal as a number with 1 in the denominator.

2nd multiply to remove 2 decimal places by (100/100)

3rd reduce the result of the multiplication

Then simplify the improper fraction
