1. you have a solid cube of dough. consider the cross sections that are formed when you slice into the cube as described. draw each slice and describe the resulting cross section. (a) a slice through the center, parallel to a side. (b) a slice that cuts through the left top edge and the right bottom edge. (c) a slice that cuts across a corner through three sides of the cube.

(a)

A square is formed.

(b)

A rectangle is obtained.

(c)

A triangle is formed.

Step-by-step explanation:

We have to tell different cross sections that are obtained on slicing a cube in different ways.

(a)

A slice through the center, parallel to a side.

( As the slicing is done parallel to the base and the cube is sliced from the center hence we will obtain the figure similar to it's base or top i.e. square)

Hence, a square is obtained.

( As the sides of a cube are squares)

(b)

A slice that cuts through the left top edge and the right bottom edge.

i.e. the slicing is done across the diagonal of a cube hence we will obtain the rectangle with dimension as one side which has measure same as the diagonal of a cube and the other side which has measure same as the measure of side of square.

Hence, a rectangle is obtained.

(c)

A slice that cuts across a corner through three sides of the cube.

This slicing will form a triangle whose three sides are the three sides of the cube through which slicing is done.

step-by-step explanation:

since the sequence is geometric there is a common ratio r between consecutive terms, that is

r = 4 ÷ - 2 = - 2

r = - 8 ÷ 4 = - 2

r = 16 ÷ 8 = - 2

the next term - 13 must be incorrect as it should be - 32 for the sequence to be geometric.

the first 4 terms are therefore geometric with common ratio r = - 2

answer:   b

step-by-step explanation:

x2 = 16

x can not be a negative number because 16 is positive

the only answer would be positive 8
