Start (90,100). End (10,0). Waterfall (70,50). The X point is first Y is second. Hope this helps :)
40-30=10
52-40=12
66-52=14
82-66=16
Each time the difference between two consective weeks gains two minutes, so if the difference between weeks 5 and 4 is =16 minutes then we add two minutes
16+2=18
Then we add the previous time to 18
18+82=100
Week 6 = 100 minutes
So the answer is A. 100
Answer:
You will subtract these top 2
- 7 {a}^{2} + 3a - 9 - 7 {a}^{2} + 3a - 9
5 {a}^{2} - 6a - 45 {a}^{2} - 6a - 4
and this bottom one is your ANSWER
- 12 {a}^{2} - 110a - 22
Answer:
The final depth of Melissa is 14 meters below the surface
Step-by-step explanation:
In this kind of problems, involving directions, etc, usually one position is the positive direction and the other position is the negative direction.
In our problem, we suppose that the surface is the positivo zero, above the surface is the positive position(positive depth) and below the surface is the negative directions(negative depth).
The problem states that Melissa is 29 meters below the surface. So, her initial position is 29 meters in the negative direction, so it is equal to -29.
Then, the problem states that Melissa rises upward 15 meters. Upward is the positive direction, so she moved to the positive direction. It means that we are going to do -29+15 = -14 meters.
It means that the final depth of Melissa is 14 meters below the surface
I = PRT/100 = (14,300 x 7 x 4)/100 = $4,004
