Mathematics
1 answer:
lawyer [7]3 years ago
6 0

Answer:

3

Step-by-step explanation:

Slope is given by

\frac{y2 - y1}{x2 - x1}

where y2 = -1, y1 = -7, x2 = -1, x2 = -3

\frac{ - 1 - ( - 7)}{ - 1 - ( - 3)}  =  \frac{ - 1 + 7}{ - 1 + 3}

=   \frac{6}{2}  = 3

I'm marking answers as brainliest ----- One of the vertices for this linear programming problem is __________. ----- (1,2) (3.5,
Travka [436]

Answer:

(0,2.3)    if only one choice expected.

(0,2.3) and (0,0)  if "all that apply" expected, since (0,0) is also a vertex of the green region.

Step-by-step explanation:

From the attached diagram, the given answer optsions are shown in brown.

The red line shows the optimal combinations of the two variables, hence a maximization problem.

Out of the four answer options, two coincide with a vertice of the valid region (shown in green), namely (0,0) and (0, 2.3).

Out of the two indicated options which correspond to a vertex, the origin (0,0) is usually ignored for a maximization problem, which leaves us with (0,2.3) as the answer.

A student drives 4.8-km trip to school and averages a speed of 22.6 m/s. on the return trip home, the student travels with an av
ArbitrLikvidat [17]

In this case, we cannot simply take the average speed by adding the two speeds and divide by two.

What we have to do is to calculate the time required going to school and the return trip home.

We know that to calculate time, we use the formula:

t = d / v

where,

d = distance = 4.8 km = 4800 m

v = velocity

 

Let us say that the variables related to the trip going to school is associated with 1, and the return trip home is 2. So,

 

t1 = 4800 m / (22.6 m / s)

t1 = 212.39 s

 

t2 = 4800 / (16.8 m / s)

t2 = 285.71 s

 

total time, t = t1 + t2

t = 498.1 s

 

Therefore the total average velocity is:

= (4800 m + 4800 m) / 498.1 s

= 19.27 m / s = 19.3 m / s

 

Answer:

19.3 m/s
