Answer:
-x∧2+2x+3
Step-by-step explanation:
(2x+2)-(x2-1)
2x+2-x2+1
-x2+2x+3
In the graph above, the correct description of any location to the left of the zero is Negative position.
c. negative position
Year 1990, dolphins were 243,000
2.3% of 24300
= ( 2.3 / 100 ) * 243000
= ( 0.023 ) * 243000
= 5589
So every year, the population of dolphins decrease by 5589.
Now from 1990 to 2030 will be
= 2030 - 1990
= 40 years
Therefore, for a year = 5589 decrease
For forty years, it will be
= 40 * (5589)
= 223560 dolphins will be lost after forty years
The remaining ones
= 243000 - 223560
= 19440 dolphins will be left
Answer:
The total payment Janie have to make is $5466 .
Step-by-step explanation:
Given as :
The loan principal = $4850
The rate of interest applied = 13.8% compounded monthly
Let The time period of loan = t years
The monthly payment she make = $455.50 each month
I.e She make payment for t years = $455.50 × n
where n is the number of terms
<u>From Compound Interest</u>
Amount = Principal × 
Or, $455.50 × n = $4850 × 
Or, 
× n = 
Or, 0.0939 × n = 
Or, 0.0939 × n = 1.14707
∴ n = 
I.e n = 12.21 ≈ 12
So, The number of terms Janie she will pay = 12
So, The total payment she have to make = $455.50 × 12 = $5466
Hence The total payment Janie have to make is $5466 . Answer
Answer:
1. Term.
2. Common difference.
3. Arithmetic sequence.
4. Sequence.
Step-by-step explanation:
1. Term: an individual quantity or number in a sequence. For example, 1, 2, 3, 5, 6. The first term is 1 while 5 is the fourth term.
2. Common difference: the fixed amount added on to get to the next term in an arithmetic sequence. For example, 2, 4, 6, 8 have a common difference of 2 i.e (6 - 4 = 2).
3. Arithmetic sequence: a sequence in which a fixed amount such as two (2) is added on to get the next term. For example, 0, 2, 4, 6, 8, 10, 12.... is an arithmetic sequence.
4. Sequence: a set of numbers that follow a pattern, with a specific first number. For example, 1, 2, 3, 4, 5, 6 is a sequence.
