Solve: log2(3x 8) = 5 which is an equivalent equation? 25 = 3x 8 52 = 3x 8 25 = [log2(3x 8)]2 52 = [log2(3x 8)]5

charle [14.2K]

The value of the equivalent equation will be 32=3x+8

<h3>What will be the value of x?</h3>

It is given in the question that

$\rm Log_2(3x+8)=5$

Now from the antilog property property

$\rm x=Log_by$ can be written as below

$b^x=y$

So the value of $\rm Log_2(3x+8)=5$ will be

$2^5=3x+8$

$3x+8=32$

Thus the value of the equivalent equation will be 32=3x+8

Determine the first five terms I. The sequence that has a recursive rule of f(n) = f(n-1) + 2 for n is greater than or equal to

eimsori [14]

Answer:

Okay let me explain this to you so you understand

So what does f(n) mean?

Well F(n) is saying the function, of n.

Basically we need to make n be any random number.

Well what number do we choose?

In your question, it says n is greater than or equal than 2.

lets start with 2

f(n-1)+2

f(2-1)+2

1+2

f(2) is 3

lets do this 4 more times

that leaves us with the first 5 terms

these 5 terms are

In circle P diameter QS measures 30 cm.

kow [346]

<u>Given</u>:

The diameter of the circle P is 30 cm.

The radius of the circle P is 15 cm.

The measure of ∠RPS is 125°

We need to determine the arc length of QR.

<u>Measure of ∠QPR:</u>

The angles QPR and RPS are linear pairs.

Thus, we have;

$\angle QPR + \angle RPS=180^{\circ}$

Substituting the values, we have;

$\angle QPR + 125^{\circ}=180^{\circ}$

$\angle QPR =55^{\circ}$

Thus, the measure of ∠QPR is 55°

<u>Arc length of QR:</u>

The arc length of QR can be determined using the formula,

$Arc \ length =(\frac{\theta}{360})2 \pi r$

Substituting $\theta=55$ and r =15, we get;

$Arc \ length =(\frac{55}{360})2 (3.14)(15)$

$Arc\ length = \frac{5181}{360}$

$Arc \ length =14.4 \ cm$

Thus, the arc length of QR is 14.4 cm.

Hence, Option d is the correct answer.
