Suppose there are 7 roads connecting town a to town b and 6 roads connecting town b to town

VikaD [51]

First, we should answer two simple questions.

1. How many ways can we travel from a-b?

2. How many ways can we travel from b-c?

This is given in the problem - because there are 7 roads connecting a to b, there are 7 ways to get from a-b. Because there are 6 roads from b-c, there are 6 ways to get from b-c.

Now that we understand this, we can use some logic to figure out the rest of the problem. Let's think about each case.

Let's go from a-b. We'll choose road 1 of 7. Now that we are in b, we have 6 more choices. This means that there are 6 ways to get to from a-c if we take road 1 when we go to b.

If we take any road going from a-b, there will be 6 options to get from b-c.

So, we can just add up the number of options because we know that there are 6 routes per road from a-b. This is simply 7*6 = 42. So, there are 42 ways to travel from a to c via b.

1) What is the shape of the graph of the following parametric equations?

yuradex [85]

Answer:

The shape of the graph of the parametric equations given is:

<u>B. ellipse</u>.

Step-by-step explanation:

By inserting each of the equations given in a graphing calculator (Annex 1), it can be identified that both the first and second equations have an elliptical or ellipse shape, which is characterized by being periodic in the two directions in which it runs. Thus, the equation x = 3 cos t runs with elliptical motion on the Y-axis of the Cartesian plane, while the equation y = 2 without t + 1 runs with elliptical motion on the X-axis.

Three consecutive integers have a sum of 48 find the integers?

zavuch27 [327]

The sum of three consecutive integers is three times the middle one: if we call the middle one $x$ , the three numbers are

$x-1,\ x,\ x+1$

So, their sum is $x-1+x+x+1 = 3x$

Which is three times the middle one.

So, if the sum of three consecutive intergers is 48, the middle one must be 48/3 = 16.

So, the three numbers are 15, 16 and 17

The length of rectangle is 5 cm greater than its width. The perimeter is 106cm. Find the dimensions of the rectangle.

antiseptic1488 [7]

Width-24 Length-29

Two sides of the rectangle are 5 cm bigger than the other two. So you would add the two 5 cm together (10cm). If you take the 10 cm off you (106-10) you will get a square. Then all you have to do is divide 96 by 4 (24), and add back on the two 5cm from the beginning to the length (29).
