Which of the following is NOT written in correct scientific notation? (In each question, the number after the ^ is the power - there's no way to do superscripts in the answer options.) Please explain how you got your answer. WILL GIVE BRAINLIEST a. 2.48 x 10^7
b. 3.5 x 10^-3
c. 24.8 x 10^6

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

step-by-step explanation:

, and

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
