Answer:
It would take 10 days to completely empty the rain gauge.
Step-by-step explanation:
Initial reading of rain gauge = 10 inches
<u>Every day rain evaporated by 2 inches but 1 more inch of rain was added.</u>
<u>In effect, only one inch of rain water evaporated that is everyday level decreased with 1 inch.</u>
After the end of day 1 , the reading would show 9 inches and 8 inches at the end of day 2 and similarly reading decreases linearly.
Since the reading should decrease by 10 inches it would take 10 days to completely empty the rain gauge.
If we make the days and ounces be in the ordered pair, the points are: (2, 39), (4, 33), (6, 27), and (8, 21). We may use linear regression from the calculator using the equation,
y = Ax + B
where A is the slope. The value of A from the linear regression is equal to -3.
Answer:
B
Step-by-step explanation:
Given that the function h(x) = 2x-9 is translated up 5 united to become a new function, i(x)
To find: Equation of new function
The graph of a function can be moved up, down, left, or right by adding to or subtracting from the output or the input.
Adding to the output of a function moves the graph up
Therefore,
Given function is:
h(x) = 2x - 9
Translated up by 5 units
Therefore, new function is:
i(x) = h(x) + 5
i(x) = 2x - 9 + 5
i(x) = 2x - 4
Thus Option B is correct
