Answer:
(-2,-1)
Step-by-step explanation:
If you look at the graph, you can see that the lines will extend upwards indefinitely, but the lines will stop going downwards at y = -1
When y = -1, x = -2
Therefore, the values of x for the given values of y when y<0 is (-2,-1)
Since the outside is 1.5 to 1, we take half of the value of the inside diameter and add it to itself to get the smallest value needed. 0.5+0.25=0.75
So the smallest diameter possible would be 0.75 inches.
We are adding 7 each time.
The formula for an arithmetic sequence is
first term+(n-1)d
Where n is the number of terms, and d is the common difference
In this case, n is 35 and d is 7
Plug the numbers into the formula and you get
-33+(35-1)7
Solve
-33+(238)= 205
10 x 15=150
150 is the answer
Answer:
3.2 km * 1 / 1.609 mi / km * 5280 ft / mi = 10,501 ft
Check: 3280.84 ft / km * 3.2 km = 10,499 ft
