Dayle only got partial credit on her assessment for calling this figure a square. Mrs. Zuber told Dayle that the directions asked for her to include all the names for this figure based on its characteristics. What are all the names that Dayle should have included in her answer to have received full credit?

, 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

the answer is b

answer: yes, since the line has a steeper rate of change than the exponential the y-values will be greater and they will only intersect one time.

60

step-by-step explanation:

every triangle measures a total of 120 degrees. you have to find angle c. we know that isosceles triangles angles are equal. 60 degrees plus 60 degrees gives you 120.
