Graphs exercise 1: (a) a simple graph of 4 vertices has eigenvalues 3,-1,-1,-1}. how many edges must it have? draw the graph (b) a simple graph has a spectrum of 4 numbers, three of which are given below (the values are rounded). find that graph (i) {-1.5, -, 0.3 (ii) { 3/5

no because mercury has a density of 13.6 grams per centimeter squared while gold has 19.32 grams centimeter squared

step-by-step explanation:

the answer is:

the correct option is the option b.

to calculate the surface area of the right cylinder, we need to use the following formula:

from the picture we know that:

so, substituting and calculting we have:

hence, we have that the correct option is the option b.

have a nice day!
