The Golden Years Senior Citizen Center uses a phone tree to announce when the center will be closed for poor weather. When each

person receives a phone call, that person has a list of three more people to call. The function c approximates the total number of calls made after m minutes since the start of the phone tree. c(m) = 3/2 * (3 ^ (m/10) - 1) Approximately how many minutes will it take for the number of calls to reach 363?

Answer:

50 Minutes.

Step-by-step explanation:

The function c approximates the total number of calls made after m minutes since the start of the phone tree.

c(m)=\frac{2}{3}\times (3^{\frac{m}{10}}-1)

We need to find the number of minutes after which the total number of calls will 363.

Substitute c(m)=363 in the given function.

363=\frac{2}{3}\times (3^{\frac{m}{10}}-1)

Multiply 3/2 both sides.

363\times \frac{3}{2}=(3^{\frac{m}{10}}-1)

242=3^{\frac{m}{10}}-1

Add 1 on both sides.

243=3^{\frac{m}{10}}

3^5=3^{\frac{m}{10}}

On comparing both sides we get

5=\frac{m}{10}

Multiply both sides by 10.

50=m

Therefore, the total number of calls will 363 after 50 minutes since the start of the phone tree.

What is the range of y=5(11)x
dem82 [27]

Answer:

Domain: ( − ∞ , ∞ ) ,  { x | x ∈ R}

Range: ( − ∞ , ∞ ) ,  { y | y ∈ R}

Step-by-step explanation:

We can simplify to understand how to answer the question better.

<em>5 * 11x = 55x</em>

<u>Function range definition:</u><u> </u>

The set of values of the dependent variable for which a function is defined.

  • The range of polynomials with odd degree is all real numbers.

<u>So the solution is.. </u>

-∞<x< ∞

<u>And the interval notation is..</u>

(- ∞. ∞)
