Answer:

The sum of this geometric series is 720.

Step-by-step explanation:

The sum of a infinite geometric series is given by the following formula:

s = \frac{a_1}{1 - r}\\

Applying the data from the problem, we have:

s = \frac{180}{1 - \frac{3}{4}}\\\\s = \frac{180}{\frac{4 - 3}{4}}\\\\s = \frac{180}{\frac{1}{4}}\\\\s = 180*4 = 720

The sum of this geometric series is 720.

If f is a function, then f(3x)=3f(x)
Delvig [45]
This is false.
The f(3x) means you are multiplying the input 'x' by 3 before plugging into the equation.
3f(x) means you are going to multiply your answer (output) by 3 after you've plugged the input value in and gotten the output.

A conductor needs 5 cellists and 5 violinists to play at a diplomatic event. to do this, he ranks the orchestra's 10 cellists an
DaniilM [7]
Ranking is very critical in this problem. Therefore, the most applicable mathematical theory is permutations.

Ranking possible for the cellists:
Needed cellists = 5
Total available cellists = 10
Possible number of rankings = 10P5 = 10!/(10-5)! = 30240

Ranking possible for the violinists:
Needed violinists = 5
Total available = 16
Possible number of rankings = 16P5 = 16!/(16-5)! = 524160

Therefore,
Ratio of rankings (cellists to violinists) = 30240/524160 = 3/52

Find the value of x to the nearest degree. <br><br>A. 35 <br>B. 28 <br>C. 51 <br>D. 55
user100 [1]

Answer:

A

Step-by-step explanation:

First, we are already given the sides adjacent and opposite to ∠x. Therefore, we can use the tangent function. Recall that:

\tan(x)=opp/adj

The opposite side is 20 while the adjacent side is 14.

Plug in the numbers. Use a calculator:

\tan(x)=20/14=10/7\\x=\tan^{-1}(10/7)\\x\approx55.0080\textdegree\approx55\textdegree

Neko [114]
Salutations!

<span>A bag contains 56 marbles: 7 red, 8 green, 11 yellow, 17 brown, and 13 blue.

If a marble is chosen at random, what is the probability that the marble is green?

Probability means an occurrence of a chance

(Probability of getting green marble) = </span>8/56

Simplify tex]8/56[/tex]

The simplified answer would be 1/7

Hope I helped (:

Have a great day!
