stira [4]

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 does a star mean after a number
Triss [41]
A star is written to show multiplication. It is a replacement for a dot or a x which is what you probably learned to be the "times" sign. In upper level maths, the "x" is replaced with a " * " to make it more legible and to avoid confusion with the variable "x".
