The series is an arithmetic series with first term -10 and common difference (-2-(-10))=8. The general term a_n can be written as
a_n = -10 + 8(n-1)
or
a_n = -18+8n
The last term corresponds to
110 = -18+8n
128 = 8n
16 = n
So, the summation can be written as
Answer:
For part one 30000 and the slope for part two is -2000 and for part three it is y=30000=2000x.
Step-by-step explanation:
If it starts at 30,000 then that is on the 0 on the x-axis.
While the plane is descending by 2000 so that is the slope but because it is descending and not rising it is -2000. If it was rising it would be 2000.
And for part three because it starts and 30000 and it goes down 2000 by the x-axis.
Hope this helps.
Answer:
the quotient of 3 and 4 subtracted from 25.
Step-by-step explanation:
QUESTION 1
When the plane reaches an altitude of 360,000 feet, the temperature outside the plane is 65 degrees below zero Fahrenheit.
This means that the temperature will be:
The temperature is -65°F.
QUESTION 2
If the temperature gets warmer by 10 degrees, this means that the new temperature will be the sum of the original temperature and 10 degrees:
The temperature is -55°F.
Answer:
x = 24, y = 15
