Answer:
at 8 pm the temperature will be -9 degrees. and at midnight the temperature will be negitive twenty one(-21) degrees
Step-by-step explanation:
the start time is 12 pm and finish is 12 am and every hour your going to subtract 3 from the given degree so 15-3= 12 , 12-3=9 ect.
what do you need help for
The answer is the first one:
bc its not growing by a (-)1/2 and the 3rd one just doesnt make sense
Answer:

Step-by-step explanation:
We want to write an exponential function that goes through the points (0, 20) and (6, 1280).
The standard exponential function is given by:

The point (0, 20) tells us that <em>y</em> = 20 when <em>x</em> = 0. Hence:

Simplify:

So, our exponential function is now:

Next, the point (6, 1280) tells us that <em>y</em> = 1280 when <em>x</em> = 6. Thus:

Solve for <em>b</em>. Divide both sides by 20:

Therefore:
![b=\sqrt[6]{64}=2](https://tex.z-dn.net/?f=b%3D%5Csqrt%5B6%5D%7B64%7D%3D2)
Hence, our function is:

I say left because you have a straight line, i goes through 0,0 and every time it goes over 1 and up by 3.
