Answer:

1. isosceles

2. Right

Step-by-step explanation:

Here, we want to give the kind of triangle in each of the diagrams

1. From what we can see, we have two sides equal to each other using the given markings. More specifically, the base sides are equal and that makes the triangle an isosceles triangle

2. From what we can see here, we have an angle of 90 degrees on one of the sides of the triangle. In other words, we have a right angle on one of the sides.

This makes the triangle, a right triangle

Jack bought 50 lbs of clay for his art projects. He used 13.2 lbs to make a sculpture, and 0.72 lbs for each mug. How many mugs

KIM [24]

Given :

Jack bought 50 lbs of clay for his art projects. He used 13.2 lbs to make a sculpture, and 0.72 lbs for each mug.

To Find :

How many mugs did Jack make if he had 28.88 lbs of clay left over.

Solution :

Clay required to make 1 mug, r = 0.72 lbs.

Amount of clay left after making sculpture is, T = 28.88 lbs.

Now, number of clay mug Jack can make is :

$n = \dfrac{28.88}{0.72}\\\\n= 40.11$

Since, number of mug cannot be in decimal, so we take the floor value.

Therefore, number of mug that can be prepared is 40 .

What key features are unique to the graphs of sequences and series and how do you find the average rate of change using the grap

andrey2020 [161]

The key features that are unique to the the graphs of sequences and series is that they are discrete.

That means that the graph is not a continuos line or curve that join all the points. On the contrary, the graph is a set of separated dots, because the values are valid only for specific points.

Regarding the average rate of change, there is not difference to calculate it respect to other graphs.

The average rate of change between points is yet the slope of the line (in this case imaginary line) that joined the first and the last point, and that is:

                                                         rise              y2 - y1
average rate of change = slope = ------------ =   --------------
                                                        run               x2 - x1
