C is the answer !!!!!!!!!
89 multiplied by .07 is 6.23 so add 6.23 to 89 aka
$95.23 is your answer
The sequence is " Algebraic, common difference = −10 " ⇒ 1st answer
Step-by-step explanation:
Let us revise the algebraic and geometric sequences
- The Algebraic sequence is the sequence that has a common difference between each two consecutive terms, like 2 , 5 , 8 , 11 , 14 , .......... the difference between the 5 and 2 is equal to the difference between 8 and 5, and the difference between 11 and 8 and the difference between 14 and 11
- The geometric sequences is the sequence that has a common ratio between each two consecutive terms, like 3 , -9 , 27 , -81 , ...... the ratio between -9 and 3 as the ratio between 27 and -9 as the ratio between -81 and 27
→ x : 1 : 2 : 3 : 4
→ f(x) : 5 : -5 : -15 : -25
x represents the positions of the terms
f(x) represents the value of each term
∵ 1st = 5 and 2nd = -5
∵ -5 - 5 = -10
∵ 2nd = -5 and 3rd = -15
∵ -15 - (-5) = -15 + 5 = -10
∵ 3rd = -15 and 4th = -25
∵ -25 - (-15) = -25 + 15 = -10
∴ There is a common difference -10 between each two
consecutive terms
∴ The sequence is algebraic with common difference -10
The sequence is " Algebraic, common difference = −10 "

Answer:
Time spend by Adelina at the tutoring session is 30 minutes.
Step-by-step explanation:
Given : In a tutoring session, 
of an hour was spent reviewing math problems and Adelina attended 
of the tutoring session.
We have to find the time Adelina spend at the tutoring session.
We know, 1 hour = 60 minutes.
Total time taken in tutoring session = 
minutes.
also, Adelina attended of the tutoring session that is of 40 minutes.
that is 
minutes.
Thus, time spend by Adelina at the tutoring session is 30 minutes.
Answer:
25
Step-by-step explanation:
g(-2) = -2(-2)+1 = 5
f(g(-2))=f(5) = 5(5) = 25
