ANSWER

B. f(x) = 3x - 8

EXPLANATION

We have the graph of a straight line given and we need to find the function that it represents.

A linear function is generally given as:

f(x) = mx + c

where m = slope

c = y intercept

So, we need to identify the slope and y intercept.

The y intercept is the point where the graph touches the y axis. From the graph, the y intercept is:

c = -8

Now, to find the slope, we use the formula:

m\text{ = }\frac{y2\text{ - y1}}{x2\text{ - x1}}

where (x1, y1) and (x2, y2) are two points that lie on the graph.

Let us use the given points:

(0, -8) and (1, -5)

Therefore:

\begin{gathered} m\text{ = }\frac{-5\text{ - (-8)}}{1\text{ - 0}}\text{ = }\frac{-5\text{ + 8}}{1} \\ m\text{ = 3} \end{gathered}

Therefore, the equation of the line is:

f(x) = 3x - 8

It is

24x - 30

The equation for area of a trapezoid is

\frac{1}{2} (a + b) \times h

Substituting our values in

\frac{1}{2} (3x + 7 + 5x - 3) \times 6

We can then simplify the expression

\frac{1}{2} (8x - 10) \times 6 \\ (4x - 5) \times 6 \\ 24x - 30

For what values of x is the inequality 2/3 + x/3 >1 true?
Travka [436]

Answer:

B

Step-by-step explanation:

\frac{2}{3} + \frac{x}{3} > 1 ( multiply through by 3 to clear the fractions )

2 + x > 3 ( subtract 2 from both sides )

x > 1

Customers enter the waiting line to pay for food as they leave a cafeteria on a first-come, first-served basis. The arrival rate
Elan Coil [88]

Answer:

The answer is B) 0.57.

Step-by-step explanation:

In this problem we have to apply queueing theory.

It is a single server queueing problem.

The arrival rate is  \lambda=4 and the service rate is \mu=7.

The proportion of time that the server is busy is now as the "server utilization"and can be calculated as:

p=\frac{\lambda}{c\mu} =\frac{4}{1*7}=0.57

where c is the number of server (in this case, one server).
