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 function is graphed below?
tester [92]
The answer for the exercise shown above is the first option, which is:
<span> f(x)=log(x-3) 
 The explanation is shown below:
 If you substitute the x in the function for values, you will obtain the graph attached above. As you can see on the mentioned graph, when the variable x has the value 4, the value y is 0. Therefore, you have:
 </span> f(x)=log(x-3) 
  f(x)=log(4-3) 
  f(x)=log(1)
  f(x)=0<span>
 </span>

The equation y=x^2-12x+45 models the number of books y sold in a bookstore x days after an award-winning author appeared at an a
romanna [79]
Answer: The first day the author reaches 100 days is on day 16.

To solve this problem, you could use a graphing calculator to graph the given equation. Then, determine when this line crosses 100. It crosses when x = 15.539. Therefore, we would have to round up to 16 so it is at least 100.

You could use the quadratic equation to solve: 100 = x^2 -12x + 45

Either you will get 16. If you use the quadratic formula, make sure to only use the positive answer.
