Consider the possible cross sections of a square
pyramid, a rectangular pyramid, and a cube.
Tell whether each of the following statements
are True or False.
a. Both pyramids have the same-shaped cross section when
sliced parallel to the base. u True u False
b. Both pyramids have the same-shaped cross section when
sliced through the top vertex and perpendicular to the base. u True u False
c. The square pyramid and the cube have the same-shaped
cross section when sliced parallel to the base. u True u False
d. Only two of the figures could be sliced in a way that
would create a shape other than a triangle or square. u True u False

step-by-step explanation:

, and

for

step-by-step explanation:

we can analyze the pattern at which the terms increase. let us denote , , , so that we can call

note the following:

the pattern: to get the next term value, we just add the next term number (e.g. 1st, 2nd, to the previous term value (term values are the given numbers in the question, 1, 3, 6, 10, 15,

from , to get to , we add

from , to get to , we add

etc.

we need to form a recursive formula, a formula that has the next term as a function of the previous term. so a possible recursive formula can be

, and for

probably .5

i can on others if necessary.

answer is 33
