Answer:
<em>The freezing point of water increases by 0.0001 degrees Fahrenheit when the altitude increases by 1 foot.</em>
Step-by-step explanation:
The model for the freezing point of water T at altitude a is:
T(a)= 0.0001a+32
The slope of this equation is the coefficient of the variable a. Since the slope is positive, it means the freezing point of water increases by 0.0001 degrees Fahrenheit when the altitude increases by 1 foot.
For example, when a=1000, the freezing point is:
T(1000)= 0.0001*1000+32 = 32.1°F
When a=1001, the freezing point is:
T(1001)= 0.0001*1001+32 = 32.1001°F
Note the increase of 1 foot in altitued meant an increase of 32.1001-32.1 = 0.0001°F
Answer:
3 or 1
Step-by-step explanation:
Answer:
The answer is D, 43 
Step-by-step explanation:
If the pile gets bigger by 8 
each week, and you want to find out how big the pile is after 3 weeks, then you have to multiply 8 
by 3 to find out how much the pile increased by.
8 × 3 = 25 
Now, you need to add this to your initial value to get the answer.
25 + 17 = 42 
Now simplify.
43
The parabola goes down(makes a sad face) because it is negative. The answer is 0,0
