Answer:
y = -7.2x + 540
Step-by-step explanation:
to find the slope I used the x-and-y intercepts: (0, 540) and (75, 0)
slope = 540/-75 or -7.2
37.5 = initial rate
44.9 = slope/rate
In problems like these, just use y = initial rate + rate(variable)
In this case, the answer would be y = 37.5 + 44.9h
What are u suppose to do in this word problem ?
Answer:
The temperature at the start is 35F
The temperature of the room is 74F
<em></em>
Step-by-step explanation:
Given
Solving (a): The temperature at the start.
To do this, we set:
So, we have:
<em>Hence, the temperature at the start is 35F</em>
<em></em>
Solving (b): The room temperature
We have:
To get the temperature of the room, we simply remove the exponential function.
So, we have:
<em>Hence, the temperature of the room is 74F</em>
