Answer:
102.5 ft
Step-by-step explanation:
The area of a rectangle is length x width.
You need to do 20.5 x 5 = 102.5
Answer:
2n^2 + n + 4.
Step-by-step explanation:
7, 14, 25, 40, 59
The differences are 7, 11, 15, 19 which is arithmetic sequence so the given sequence is quadratic.
Compile a table:
n 1 2 3 4 5
term 7 14 25 40 59
Diff: 7 11 15 19
Diff: 4 4 4 - this indicates that first part is 2n^2.
2n^2 2 8 18 32 50
term-2n^2 5 6 7 8 9
- the nth term for the last sequence is 5+ (n - 1)d =
= 5 + (n - 1)* 1
= n + 4.
So nth term for the original sequence is 2n^2 + n + 4.
Answer:
B. Any integer greater than 0
Step-by-step explanation:
The domain of a function is the complete set of possible values of the independent variable. It is the set of all possible values of t which will make the function "work", and will give a result for the Air Pressure, P(t).
Since Time(t) is a continuous function, the domain could take on any positive real number. Since, we are looking for the best description of the domain, Option B (any integer greater than 0) would be suitable.
This is because choosing any real number in Option A will accept negative values and time cannot be negative.
Slope equals the change in y divided by the change in x.
To tell the change between two number, we subtract them.
So first, we have to find the cooirdinates of the number to subtract them. The first one is (-2, -1), and the second one is (2, -4)
Change in x is 2 - (-2) or 4, and change in y is -4 -(-1) or - 3
-3/4 is negative three fourths so the slope is
-3/4
