Answer:
y = 6^x -3
Step-by-step explanation:
The graph is that of an exponential function that has been translated downward. We notice the horizontal asymptote is -3, and a couple of points on the graph are (0, -2) and (1, 3).
The shifted parent function will look like ...
y = a·b^x +c
where c is the horizontal asymptote. Using the two points we found, we have ...
-2 = a·b^0 -3 . . . . . using (x, y) = (0, -2)
1 = a . . . . . . . . . . add 3 and simplify
Then using (x, y) = (1, 3), we have ...
3 = b^1 -3
6 = b . . . . . . . . . add 3 and simplify
So, the equation is ...
y = 6^x -3
Answer:
Her average time was 8.1 minutes per mile.
Step-by-step explanation:
<span>A=1/2 h (b1 + b2 ) .. solve for b2
First, multiply both sides of the equation by 2.
</span><span> 2A=h(b1 + b2)
Now divide both sides by h.
2A/h = b1 + b2
Finally, subtract B from both sides.
(2A/h) - b1 = b2
This can be simplified to
b2 = 2A-hb1 / h
