Please help me with this

Gnoma [55]

Given:

The equation is:

$3^x\times 9=3^{2n-1}$

To find:

The value of n in terms of x.

Solution:

We have,

$3^x\times 9=3^{2n-1}$

It can be written as

$3^x\times 3^2=3^{2n-1}$

$3^{x+2}=3^{2n-1}$ $[\because a^ma^n=a^{m+n}]$

On comparing the exponents, we get

$x+2=2n-1$

Add 1 on both sides.

$x+2+1=2n-1+1$

$x+3=2n$

Divide both sides by 2.

$\dfrac{x+3}{2}=n$

Therefore, the value of n is terms of x is $n=\dfrac{x+3}{2}$ .

Which of the following are identities? Check all that apply. A. cot2x + 1 = csc2x B. tan2x = 1 - sec2x C. sin2x = 1 + cos2x D. s

kirill115 [55]

I'll assume those are squares. We know D is an identity:

$\sin^2 x + \cos ^2 x = 1$

Dividing through by $\sin ^2 x$

$1 + \cot^2 x = \csc^2 x$

That's A.

Dividing the original through by $\cos ^2 x$

$\tan^2 x + 1 = \sec^2 x$

Not quite B, wrong sign on tangent.

C has the wrong sign on cosine squared as well.

Identities: A & D

kristy asks lonnie to think of a number, add 3 to it, multiply the sum by 2 and then subtract 6 . let n stand for lonnies starti

The expression that represents Lonnie's final number is 2(x + 3) - 6

<h3>Writing an expression</h3>

From the given information, we are to write the expression that represents Lonnie's final number

From the given information,

"<em>kristy asks lonnie to think of a number, add 3 to it</em>"

Let the number be x

Then,

The statement becomes

x + 3

<em>"multiply the sum by 2</em>" we get

2×(x +3)

= 2(x + 3)

"<em> subtract 6</em>",

The expression becomes

2(x + 3) - 6

This is the expression that represents Lonnie's final number

Hence, the expression that represents Lonnie's final number is 2(x + 3) - 6
