Recall that in order to start the scavenger hunt, Darnell needs to send an encoded message to Raya.
a) Based on the table, what is the number string that corresponds to the text “Hello Raya”? (1 point)
b) How many 2 x 1 matrices will be in the sequence? How do you know that? (2 points)
c) Write the sequence of 2 x 1 matrices that Darnell will use to encode. (1 point)
d) What is the enumerated matrix B? (2 points)

a net is a diagram that shows a “flattened” view of a solid. in a net, each face and base is shown with all of its dimensions. a net can also serve as a pattern to build a three-dimensional solid.

a pyramid is a three-dimensional object with a base that is a polygon and triangular faces that meet at one vertex.

" the net of a triangular pyramid consists of four triangles. the base here we are given of the pyramid is a equilateral   triangle, and the lateral faces are also triangles "

doubled

step-by-step explanation:

answer: 4  

the square root of 16 is 4. it is a very simple mathematic concept. a square root when a number multiplied by itself will result in a number. here, the number 16 comes when 4 is multiplied by 4. hence the square root of 16 is 4. you can always figure out a square root by the inverse operation of squaring.  

b

step-by-step explanation:

multiply terms on numerator/ denominator by (x - 1)

= ← distribute numerator/ denominator

= ← simplify

=

= → b
