Answer:
They ordered about 52.
Step-by-step explanation:
Divide- 833÷16= 52.0625
It is estimated to only 52 pounds.
I believe that the answer is speed in this situation but I'm not 100% sure
Answer: -1/2
Step-by-step explanation:
The average rate of change is 
. Since a=-1 and b=1. We can plug them into the equation and solve.
![\frac{[1^2-1-1][(-1)^2-(-1)-1)]}{1-(-1)} =\frac{(-1)(1)}{2} =-\frac{1}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B%5B1%5E2-1-1%5D%5B%28-1%29%5E2-%28-1%29-1%29%5D%7D%7B1-%28-1%29%7D%20%3D%5Cfrac%7B%28-1%29%281%29%7D%7B2%7D%20%3D-%5Cfrac%7B1%7D%7B2%7D)
Answer:
20. y = 3·3^x
21. y = (1/3)^x
Step-by-step explanation:
These exponential functions can be written in the form ...
y = a·b^x
where a is the value of y when x=0, and b is the common ratio between terms that have x different by 1.
__
20. The ratio is 9/3 = 3; the multiplier is 3 (the value of y when x=0), so the function is ...
y = 3·3^x
__
21. The ratio is (1/3)/1 = 1/3; the multiplier is 1, so the function is ...
y = (1/3)^x
_____
<em>Alternate solution</em>
Each of these can be written in a more compact form:
20: y = 3^(x+1)
21: y = 3^(-x)
