Video rental stores are being replaced by streaming subscriptions. In one area, there were 10 video rental locations in 1996, bu
1 answer:
Answer:
The unit rate is -1 store per year
Step-by-step explanation:
Let
x -----> the number of years since 1996
y ----> the number of video rental stores
we know that
The year 1996 represent x=0
so
2016 represent ----> x=2016-1996=10 years
we have the points
(0,10) and (10,1)
The unit rate is equal to the slope of the linear equation
<em>Find the slope m</em>
----> is negative because is a decreasing function
therefore
The unit rate is -1 store per year

The length of the diameter, in meters, of the circular area that gets watered by the sprinkler for this condition is given by: Option B: 8 m
<h3>What is the equation of the circle of radius r units, centered at (x,y) ?</h3>If a circle O has radius of r units length and that it has got its center positioned at (h, k) point of the coordinate plane, then, its equation is given as:
For this case, the equation of the circle that models tha circular area considered is:
Writing this in standard form and comparing it with the standard equation, we get:
(didn't took (-4)² = 16 since radius cannot be negative).
Thus, we get center's coordinate as (9,-11) and radius of 4
The diameter of that circular area = twice of radius of the circle which models it = 2 × 4 = 8 meters.
Thus, the length of the diameter, in meters, of the circular area that gets watered by the sprinkler for this condition is given by: Option B: 8 m

Answer:
The attached graph shows my answer.
Step-by-step explanation:
The graph has to start at the top because the number of carrots has to decrease and the graph slants down to the right because the time has to increase. Then the situation says that he eats one carrot at a time until <u>half</u> are eaten. The graph shows the line going down until approximately half. Then he doesn't eat any more, so the line is horizontal until the end of the graph to show no change.
